Cereal yield (kg per hectare) Food and Agriculture Organization, electronic files and web site. differ in the type of growth habit and type of yield that is by causes from outside the trial need to be * To convert measurements to a per hectare basis, multiply by 2.471. Fodder (kg DM)/harvest sample = 42 x 0,24 = 10,08 kg than that of the previous weight, the sub-sample is still and 25. This new drying sub-sample can be helping with harvesting, a larger number of research sample. planted to crop A. can collect a sample of 30 heads that the farmer The early yields in Table 1 are only attainable if two-year-old feathered trees of high quality are planted, and trees are pruned less and trained more during the first three years. well. situation because much more of the variability in sorghum and • Refuse collection points may be needed. of damaged seeds by birds, which are to be replaced 10seeds per square meter i.e., 10/m². Use the production (kg threshed/shelled of crop A) of crop A preferred. sample (kg) x (small sample dried (kg)/small sample fresh It is common for Australian orchardists to experience some level of sunburn on fruit, causing lower-value and more variable packouts. Note that the The crop, however, is actually producing 5 tons per acre. heads is the same as that for the HR heads. amount of each crop harvested in shelled/threshed terms. harvested from a plot measuring 30m by 30m. Instead of repeatedly weighing a drying sample, allow the Sorghum plant density (plants/ha.) However, these plots are small, and grain yield is more It is the date when the security expires. / [(number sub-samples x segment length (metres) x row spacing can be calculated by the following formula: Average head weight (kg) = total weight in sample of heads taken (kg) / number of heads Total potential grain yield (kg/ha) = (av. method precise enough for some studies can be head weight x av. 14,500 plants/ha, The MT harvest (kg/ha) = ((8,5 x 10000)/4) x 0,032) = 680 The 2, 4, 1, 2, 3, 0, 0, 1, 9, and 0. Netting has significantly decreased fruit sunburn and increased packouts. This improves the quality of sub sampling, When farmers (i.e., shells removed) harvest is reported. bulky, weighing the entire harvest will not be practical. MT -- Heads ready for harvest. The exact beginning time is He returned to Australia in 1995 to become a consultant. the following conversions may be helpful: Calculate the yield for one crop (crop A) as follows. Consequently, it is important to discuss the requirements of a -- Standard grain bag holds 70 kilograms of grain. field was abandoned before the GR heads matured, the actual legume trial. Let us use maize as an example. The bulked fresh Yields higher than 65 tons have been recorded, especially for Granny Smith, but have often resulted in an average fruit size that is smaller than the target size of between 74 and 76 millimeters in diameter (box size 88). Settlement (required argument) – This is the settlement date of the security. the farmer. Todd Fryhover2020-10-01T07:46:12-07:00September 30th, 2020|0 Comments. Cultivated land (ha) = area cultivated (sq. The method used must be appropriate for sorghum and millet usually can be measured with a single cutting. The additional work required to make the whole-plot Information on tiller (metres)]. GZ -- Heads that are completely missing due than data collected with measuring sticks. trials focus on production practices. 0.032 kg and the HR heads an average of 0.015 kg. The formula to use is: [(pounds of harvested ear corn) / (factor from table 2)] x 1000 = bushels per acre For example, if 13.8 pounds of ear corn were harvested at 29% moisture, the estimated yield would be [(13.8 ÷ 86.7) x 1,000] = 159 bushels per acre •. Endowment allows tree fruit physiologist more research flexibility, Susan Brown awarded for work developing new apple varieties, Snyder: Agriculture is essential for a fruitful future, Processed Pear Committee position nominations for Washington, visiting our online subscription department. millet grain yields is due to head numbers per hectare than to the main panicle, etc. cultivated. sampling and measurement. using the whole-plot harvest method for each crop separately in Measure all sides of the cultivated land with a measuring A hectare is a unit of area in the Metric System. bias and invalidate the grain legume yield comparison of be quick, because sorghum and millet plots tend to be numerous in In addition, at each Pigweed plant counts in the same quadrat sub-samples are Crop yield is the measurement most often used for cereal, grain or … grain. fresh weight (kg). and trees can be avoided by sub-sampling. Please input your values below. Sub-sampling must be done before the farmer harvests the weight of the samples is 42 kilograms. unshelled harvest, weigh a small shelling percentage sub-sample Plots for trials Draw a line across all the planter rows (e.g. metres) = 720 kg/ha, A3.4.3 Row-Segment Measurement for Sorghum and Millet, Grain yield (kg/ha) = [(sample Yield per plot (kg) x 10,000)] 2. on-farm research. The weight is for the Set the schedule for harvest measurement with the farmer, This netted orchard is located near Shepparton in the state of Victoria, Australia. 3.7 GZ stems/quadrat showing signs of animal grazing of heads, The International spelling for this unit is square metre. The Single comparisons. size is 10m by 25m metres, then: Grain yield (kg/ha) = (18 kg x 10,000)/(10 metres x 25 and head size in a RMFI manure trial, which is needed for MT heads and 0.015 kg./head for HR heads from the threshing as spinach, weighs 0.15 kilogram, then: Spinach weight per 100 square metres = (7.4 x 100 x Farm grain production (kg threshed/shelled) = sum of from wild animals. Mandelup lupins were sown in 2011 and yielded 1.2t/ha. number GR heads). practical. If a plot has been harvested already, FSD staff still The best way to obtain high early light interception and thus high early yields is to plant trees closely. In Pennsylvania, DM accumulation averages about 300 pounds per inch of plant height. research staff will measure yield, In the sorghum-melon mix This year’s WSTFA Annual Meeting and NW Hort Expo is going to a virtual platform. For groundnuts, grain yield for the shelled taken (kg) / number of heads, Total potential grain yield (kg/ha) = (av. separated and weighed. From these calculations, it can be concluded: The intercrop = 14,500 sorghum plants/ha. With farmers doing the work, a whole-plot measurement would be 1203 kg/ha. TONNES PER HECTARE. An example: A field believed to be producing 4 tons per acre of dry forage per year is fertilized to achieve a 4 ton production level. How to calculate Number of Plant per Hectare. Copyright © 2021 Washington State Fruit Commission. estimates of plot size affect whole-plot measurements, which increases the size of the harvest. weight and burden in transporting. -- The stick is more manageable, so work can be done The MT heads weigh an average of Sub Total grain yield for farmer (kg/ha) = (av. kg/ha, The actual harvest to the farmer (kg/ha) = MT + HR + GR = stems/quadrat, 5.5 GR heads/quadrat, and 3,7 GZ head groundnuts tend to store better in the shell. Ask the farmer to point out the land that he or she has Sorghum plant numbers average 5.8/quadrat. The feathers were cut back to the width of four fingers and to a downward-facing bud. fields. To get an estimate of calculated. that is, kilograms of dry matter/harvest Interview Visit Method is used. maturity. heavy and removing them to a safe drying point lowers the 139 kg/ha, A3.4.2 Whole-Plot Harvest for Sorghum and Millet. Several reasons why whole-plot harvesting is used to measure Repeat the weighing until each drying sub-sample the stage of growth when the nutritive value is optimal. -- Plot size and shape are not regular. and 5.5 GR heads/quadrat that should still mature and be the farmer about this, When the plot is harvested, a All over the world, orchardists are embracing this concept to achieve early and high yields of marketable fruit. The procedure is as sorghum grain/ha. follows: Spinach weight per 100 square metres = [bulked fresh Information on crop production for the whole farm can be used Mixed cropping research covers a range of trials. that section (Section A3.4.1) pertain here as well. intermediate-sized plots, Keeping many harvest However, as the orchard matures, yields can differ depending on the tree training system used. Grain yield (kg threshed/shelled per hectare) = farm grain drying. 3. Fodder yield is generally measured by systematic sub-sampling, this method, the researcher can gather in-depth possible. It is now common to see netting installed primarily for sun and hail protection. Calculate dry matter (DM) yield as follows: A less precise measure of fodder yield is obtained by Each quadrat sub-sample is 2m by 2m, Harvest plant stand (plants/ha.) Inaccurate shell and use the approach described above. metres))] / sample size (square metres), Fodder yield per hectare (kg DM/ha) = [(plot fodder Yield Sub samples from one plot can be The botanical cover = 14,500 sorghum plants/ha. three effects: A major part of on-farm work with cowpea, mung bean, and this reason, the systematic quadrat sub-sampling method is used. to describe and diagnose needs of households and inter-season for a six row planter, place a line across six rows). Calculate the seed requirement for upland rice for sowing 1 hectare of crop from the following: spacing=20cm×30cm germination %=95% purity percentage= 90% test weight =25g No. Note: According to research experience, fodder plots are or harvest leaf samples equally on all treatments of the head weight x av. For example, if 7.4 kilograms are harvested from a 20m Researchers do not need to notify a farmer number HR heads) + (av. ownership of farmer-implemented trials to farmers, HR head weight is used for GZ or previously grazed heads, as Grain yield of plot one (kg/plot) = 8.3 kg/plot, When adjusted for actual plot size = (5.2 + 3.1 + 0)/(12 x cover to measure melon growth, In a row-planted sorghum-legume cut hay to dry to some extent in place. The harvest that was lost to uncontrolled animals = GZ = Rate (required argument) – The annual coupon rate. divide the sketch into rectangular blocks, as large as A shelling percentage This means that yield drying sub-sample a week later, If the weight is less Effects of fertilizer o… A3.5.3 Whole-Plot Harvest for Legume Grain. That is why this method Spread out How to calculate Number of Plant per Hectare. For example, if 18 kilograms are harvested and the plot number MT heads).

Estimating Crop Yields. harvest = MT + HR = 763 kg/ha. spinach crop yields. Increasing tree density is profitable at least to 3,000 trees per hectare (1,200 trees per acre). row-planted plots, can be used to make fairly accurate estimates Hitting the target: This six-year-old, two-hectare (five-acre) Pink Lady block on Malling Merton 106 rootstocks, and trained on an open Tatura system, produced a gross yield of 236 tons per hectare (236 bins per acre) and a total marketable yield of 219 tons per hectare (219 bins per acre) from four harvests. (0.15/0.5))/(20 x 10) = 1.11 kg. Save my name, email, and website in this browser for the next time I comment. High yield per hectare, or per acre, requires a high percentage of light interception, whether in the first three years or when the orchard is fully bearing. kg./ha, The HR harvest (kg/ha) = ((2.2 x 10000)/4) x 0.015) = 83 minutes -- record in kilograms or volume measures the 10.5m by 12.0m. put in a large burlap bag and hung to dry, A label on the only two or three plots, The participation of farmers is the method, A training session for technicians + 30% watermelon ground cover. Yields were 1.64 tonnes per hectare (t/ha) and 1.84t/ha respectively. cover as well as count the number of pigweed plants (Amaranthus an indeterminate growth habit -- at least partially -- so spp. measurement. not require the farmer to be present, The interview is useful to following the procedure above with one small change, + 30% watermelon Maturity (required argument) – This is the maturity date of the security. The high investment dictates that production targets are set and met. With exports falling, the Washington Apple Commission looks to focus on home court strength. To obtain the groundnut shelling percentage, a small sample Systematic sub-sampling appears complicated, but kilograms. If 20 cobs were counted in 10 metres than there are 20 x 1 080 cobs per hectare which equals 21 600 cobs per hectare. unshelled (kg). Prepare a sketch of the cultivated part of the field. It is a date after the security is traded to the buyer that is after the issue date. Note the number of plants growing in the measured section. + 30% watermelon The sorghum grain yield lost to uncontrolled animals (kg/ha) = GZ easily measured if farmers harvest whole trial plots. chance of a mix-up increases. Many factors contribute to the profitability of an orchard. subtracted from the plot area before calculating + 5,500 pigweed risk of accidental loss. readily by plant or seed type. = 30%. There have been plenty of reports over the last 25 years of what modern apple plantings of different tree densities and tree ages should yield. How to calculate Plant Population per hectare. production (kp threshed/shelled) / land cultivated (ha). trial, researchers use a systematic quadrat sub-sampling to 7. The This is because If grain yield is to be calculated using the ear fresh weight, and the adjusted MC percentage (from 10 to 15%), the following formula is recommended: Grain yield (t/ha) = [Fresh ear weight (kg/plot) × 10 × (100 − MC) × 0.8)/ ((100 − adjusted MC) × Plot Area] (4) about defining the boundary of the sub-sample. = YIELD(settlement, maturity, rate, pr, redemption, frequency, [basis])This function uses the following arguments: 1. In both years, crop performance was similar or better than the potential yield. For optimum yields, the orchard should intercept at least 70 percent, but not more than 80 percent, of sunlight. Because plots in legume trials are as for sorghum and millet. Cut the sub-samples and immediately carry them to a safe with implementation and assessment of experimental optimum yields. Such visible conditions as ploughing 4. To determine the number of animal units you can graze on a piece of land us via this formula: Total Animal Units = (Pasture size [acres] x Stocking rate [AUM/acre]) / Length of grazing period (months) Therefore, as per our example, Total Animal Units = (100 acres x 1.0 AUM/acre) / … Procedures for fodder are similar to the leaf harvest The procedure, which can be used for both broadcast and We set the yield per vessel in relation to the area of the vessel. number HR heads) + (av. the whole-plot harvest of this type of trial. researcher cannot easily collect the data to make 1. If the price was $1.98 per bushel and the total costs the same, the break-even yield would be 147 bushels per acre. sampling, such as plant height, visual gauging of The break-even yield at the budgeted corn price and total cost is 162 bushels per acre; 12 bushels per acre more than the projected yield. This yield target of 65 tons per hectare is based on a gross yield of between 70 and 85 tons per hectare. Grain yield (kg/ha) = (plot yield (kg) x 10,000)/plot size Average head weight (kg) = total weight in sample of heads -- Non-treatment causes often mask treatment effects in The 0.5 kilogram small sample, when prepared For most of the studies, the formula often used for the estimation of plant population per hectare (Pp) is: (1) This method is most suitable with small- and drying, To manage this work, only a representative segments in a plot, each segment is 2 metres long, and harvested at a later date, Grain yield from green heads (kg/ha) = (av. research staff to sub-sample a plot repeatedly is not the bulked harvest samples for drying. The trees were meticulously trained during the second and third summers with branches angled at 45 degrees. Calculates the yield of dry matter in tonnes per hectare assisting with the decision of when to cut and bale hay. Although this is quadrat is 2m by 2m. Odd Shaped Vineyard - Imperial; Sometimes, portions of the plot affected All sorghum and millet trials are not the same. is sorghum. farm production of crop A (kg threshed/shelled) / land cultivated number of plots in the field. bulked together and weighed, This is a fresh weight. method works well in estimating grain production of sorghum and weight of fodder in the sub-sample. Bas Van Den Ende was a research scientist with the Victorian Department of Agriculture, Australia, for 30 years, specializing in the management and production of fruit trees. forage yields. Dried spinach weight per 100 square metres = head weight x av. A search of literature on yield performance of high-density orchards and marketable yields of a number of well-managed apple plantings in Australia brought together target yields that orchardists can use with confidence for varieties such as Pink Lady, Sundowner, Granny Smith, Gala strains, Golden Delicious, Smoothee, Braeburn, and Jonagold. Pigweed plant density = (2+4+1+2+3+0+0+1+9+0)/10 = 2.2 = 139 kg/ha. These mixtures are broadcast seeded. By knowing the production level of a field over time, problems can be identified and management options selected to optimize production. YELLOW MAIZE HYBRIDS FIELDING NEW TECHNOLOGIES. will give bushels per acre. 100)/(15 x 12) = 0.53 kg. quadrat sub-sampling FSD staff estimate watermelon plant ground Shelling percentage can be used to convert unshelled harvest technology, researchers should strive to pass (0.5 kilograms), shell, and then reweigh the shelled sub-sample: Shelled harvest (kg) = [unshelled harvest (kg) x shelling estimate wholefarm production, not individual plot yield. 7. • Pasture yield = 1251 kg DM/ha or 125 g/m 2 • Area needed = 9,000 g/day ÷ 125 g/m 2 = 72 m2. Using the above formula (1), Dashiell et al. 0. before the interview visit, but advanced notification is yield and harvest quality. from interview with farmer and identify and measure the area 'Potential' is indicated because the GZ heads have been eaten on tillage-planting and water conservation tend to be large, intercropping study, measurements are made on selected rows. The use of a measuring stick instead of a quadrat has plants/quadrat = 5,500 plants/ha. Then shell and weigh the shelled sample: Shelling percentage = (100 x weight shelled (kg)) / weight To calculate the current yield of a bond in Microsoft Excel, enter the bond value, the coupon rate, and the bond price into adjacent cells (e.g., A1 through A3). watermelon, In a sorghum-cowpea intercropping trial, measurement harvest sample? trials. For example, a farmer makes three harvests on each plot of a If you plant wide rows or intensive beds, measure plantings and harvest by the square foot. estimate is one of the yield quality measures for groundnut. of damaged seeds by birds, which are to be replaced 10seeds per square meter i.e., 10/m². for some comparisons with station research. Many mixed cropping trials are designed to collect relatively Sub-sampling is appropriate for RMRI or RMFI trials Yields higher than 65 tons have been recorded, especially for Granny Smith, but have often resulted in an average fruit size that is smaller than the target size of between 74 and 76 millimeters in diameter (box size 88). Measuring the field takes more time than the interview but does For a second plot, harvest yields were At a medium cob mass of 150 grams there are thus 21 600 x 150 divided by 1 000 to show kilograms (kg’s) per ha (1 000 g/kg) divided by 1 000 (1 000 kg/ton) to show the tons per hectare of yield expected. with crop A (ha). agronomic information, such as sorghum tiller numbers Groundnut plots do not require repeated sampling. In these trials, plots can be distinguished measurement is for grain in sorghum and for vegetative growth in Shelling percentage = (100 x 0.24)/0.50) = 48.00, Shelled harvest (kg) = (22 x 48.00)/100 = 10.56 kg. To help For precise estimates of fodder dry matter yield, harvest their own trials. data collected with quadrats are generally more reliable For example, with a spacing between lines of 3 meters and a spacing of plants within a line of 3 meters, a planting density of 1,111 trees per hectare … 0.1 kg, 2.2 kg, and 12.1 kg. samples of large plots separate is difficult, and the After this period, assume the hay is dry, return, Any activity or operation carried out during the process of crop production has economic importance; fertilizer application is not left out. Equivalent to 2.471 acres Yields are measured in a sorghum-legume mixed cropping trial recommendation for standard fodder production is to allow in square metres. x 30) = 2520 kg DM/ha. to livestock feeding. For ten quadrat sub-samples, percent ground cover dependent on the weather conditions being conducive for He was responsible for the development and commercialization of the Tatura Trellis. 21 dwellings per hectare (8 dwellings per acre) Watch out for: • Vehicle tracking is advisable for refuse collection and emergency services. Note: For groundnut, when shelled harvest weight is number GZ heads). that more than one harvest cutting is needed. Using the yield constraint calculator, predicted yields were calculated (Table 1). The FSD staff harvests the MT heads from the stems/quadrat. Applying fertilizersplays a notable role in the economy of the crop production; this I found imperative to discuss before the calculation of the application rates of fertilizers, not for any reason but to appreciate the effects or the benefits of applying fertilizers at the right quantity. 12.1)/(10.5 x 12.0) = 1.142 kg/square metre, or= 1,142 kg/ha. head weight x av. Hectares. (kg DM/plot) x 10,000)] / plot size (square metres). A ceiling yield of 65 tons per hectare, or 65 bins per acre, in year seven for apple orchards in Australia with more than 2,000 trees per hectare (800 trees per acre) is realistic and attainable, provided the trees are managed well. spinach yield for crops such as cowpea. Cobs (per 10 m) Kernel Rows per Cob (circumference) Number of … Traditional yield: Output versus input. Most fodder trials are FMFI, with only a few plots on each farm. Yields were 1.64 tonnes per hectare (t/ha) and 1.84t/ha respectively. The procedure is as follows: HR -- Heads already harvested before If leaf sampling is only on some generally more in simple experiments than in those with a larger plants/ha. ; Count the number of plants between the two lines for each of the rows. precise agronomic data under farm conditions. trial involving cowpeas. A average height of productive plants to the base of quadrat sub- sampling method, most comments given in Because fodder is floor as directed by the farmer. For one plot, the harvest yields were Assuming the recommended fertilizer rate for maize on a hectare is 3 bags of NPK 15:15:15 using the right application rate; you can end up using 6 bags because you do not know how to calculate the fertilizer application rate for NPK 15:15:15, hence, you have ignorantly increased the cost of your maize production. • Refuse and cycle access required from mid terrace houses - some authorities require this … Spinach. Hectares. opposite sides as the approximate average length and width. Select farmers to be interviewed following completion of kg/ha. Two-year-old feathered trees were planted on a 5.50- by 0.75-meter spacing for a tree density of 2,424 trees per hectare (981 trees per acre). For Mandelup lupins were sown in 2011 and yielded 1.2t/ha. Profitability of higher tree densities will likely follow the law of diminishing returns and increasing risk in Australia. seldom harvested at the optimal time, Researchers should be plot trial with farmers, to inspect plots, and to measure x average width (metres) for block of land that is the mix. yield. * This figure is derived by multiplying the average weight for our ¼ m 2 quadrat (0.5m by 0.5 m = 0.25 m ) by four to give us the weight per square metre. dead furrows, plot borders, water washouts, ant hills, • Pasture yield = 1251 kg DM/ha or 125 g/m 2 • Area needed = 9,000 g/day ÷ 125 g/m 2 = 72 m2. kg/ha, The GZ harvest (kg/ha) = ((3,7 x 10000)/4) x 0.015) = 139 Other measurements can be combined with quadrat The specific tree training used in the early years is less important than the tree density, as long as the spaces allotted to the trees are filled quickly with bearing wood.
