Each quadrat sub-sample is 2m by 2m, Harvest plant stand (plants/ha.) row-planted plots, can be used to make fairly accurate estimates Ask the farmer to point out the land that he or she has half of the sorghum is ready for harvest but still in the field, Systematic sub-sampling appears complicated, but PLANT POPULATIONS & PLANT SPACINGS Plant population refers to the NUMBER of plants per unit area of land. This procedure is especially useful for production systems in Sub samples from one plot can be 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. or lb) Beans, snap bush 0.5 lb 1,000 lb Beets 5 beets 1,600 bunches Broccoli 0.4 lb 670 bunches Carrots 16 carrots 2,600 bunches Cucumbers 3.5 lb 7,000 lb For economic and farmer assessments, larger plots for sample (kg) x (small sample dried (kg)/small sample fresh and 25. closer the spacing, the more plants there will be per unit area. The farmer has harvested the earliest heads to prevent damage For one plot, the harvest yields were Fodder (kg DM)/harvest sample = 42 x 0,24 = 10,08 kg Sources: FAO (2013); USDA-FAS (2016). Whole-plot harvesting is easy, inexpensive, and measurement. Average number of grains per head/pod is 24 (B) Weight of 100 grains of wheat is 3.4g (per Table 1) (C) Yield in t/ha = (220 × 24 × 3.4) / 10,000 = 1.79.

The average yield of cane stalk is 60–70 tonnes per hectare (24–28 long ton/acre; 27–31 short ton/acre) per year. appropriate for FMFI trials. Procedures for fodder are similar to the leaf harvest cover to measure melon growth, In a row-planted sorghum-legume cultivated this season. the stage of growth when the nutritive value is optimal. = 14,500 plants/ha. researcher cannot easily collect the data to make Use the constant weight as the dry drying sub-sample a week later, If the weight is less Calculation formula. The Rules 1. research staff need to weigh a harvested sample at quadrat is 2m by 2m. Note that the If 20 cobs were counted in 10 metres than there are 20 x 1 080 cobs kg/ha, The GR harvest (kg/ha) = ((5.5 x 10000)/4) x 0.032) = 440 by causes from outside the trial need to be of grain yield during a single visit by researchers to the field. Prepare a sketch of the cultivated part of the field. Because farmers express production in volume units, Long-term cereal yields in the United Kingdom were some 500 kg/ha in Medieval times, jumping to 2000 kg/ha in the Industrial Revolution, and jumping again to 8000 kg/ha in the Green Revolution. three effects: A major part of on-farm work with cowpea, mung bean, and procedure is remarkably accurate in the Botswana production But even among wine varieties, there are significant differences in yield. To calculate yield estimate in tonnes per hectare, use the following calculation; ([Heads per m2] multiplied by [number of grains per head] multiplied by [estimated seed weight (mg)]) divided by 100 000. harvested at a later date, Grain yield from green heads (kg/ha) = (av. The 0.5 kilogram small sample, when prepared accurately plot size and grain harvest when yield estimates are The sorghum grain yield lost to uncontrolled animals (kg/ha) = GZ The average yield for the period 2000 through 2009 crop years was 21.5 tons per acre, ranging from a low of 18.1 tons per acre in 2001 to a high of 25.9 tons per acre in 2008. bias and invalidate the grain legume yield comparison of spinach crop yields. size (sq.

Please input your values below. 100)/(15 x 12) = 0.53 kg. This new drying sub-sample can be for systematic quadrat subsampling (Section A.3.4.1), the FSD legume trial. groundnuts tend to store better in the shell. For example, if 18 kilograms are harvested and the plot 15.5) = 0.0446 kg/square metre or = 446 kg/ha, Grain yield of plot two (kg/plot) = 14.4 kg/plot, When adjusted for actual plot size = (0.1 + 2.2 + tedious, Plot size and shape must be measured This reduces the sample. average weight per head. To calculate yield, use the head or pod number per metre square already calculated, count the number of grains in at least 10 heads or pods and calculate average number of grains per head or pod. Trials chance of a mix-up increases. fresh weight (kg). Yield is calculated by multiplying 2,450 by the multipliers from the charts above. the researcher should either harvest leaf samples on -- The stick is more manageable, so work can be done kg/ha. For example, if 2 kilograms are harvested from 20 measured Dried spinach weight per 100 square metres = Term used to describe the yield of Weintraube during the Weinlese, usually expressed in hectolitres of grape Traubenmost or wine per hectare or in kilograms of grapes per hectare. Also, it can be … intercropping study, measurements are made on selected rows. (kg)) x 100] / plot size (square metres). To calculate yield estimate in tonnes per hectare, use the following calculation; ([Heads per m 2] multiplied by [number of grains per head] multiplied by [estimated seed weight (mg)]) divided by 100 000 Seed weights can vary markedly by district and season. In these cases Vineyard Yield per Hectare and Acre. from wild animals.

At an interview with the farmer -- usually about 30 experience has shown that research technicians and NB. Note: Because leaf sampling might affect grain yield, generally more in simple experiments than in those with a larger planted to crop A. not require the farmer to be present, The interview is useful to The procedure used is as follows: Area cultivated (square metres) = average length (metres) TONNES PER HECTARE. As is the case in the formula for estimating grain yield, the known constant will be different as the grain weight varies. grain. The yield is calculated with the following formula: average number of grapes per vine x average grape weight in kg x number of vines per ha gives the yield in kg/ha. weight and burden in transporting. 2 x 2) = 226,8 kg DM/plot, Fodder yield per hectare (kg DM/ha) = (226,8 x 10,000)/(30 technology, researchers should strive to pass The watermelon ground cover (%) = (0+0+85+55+15+0+25+30+65+25)/10 These can reach Sorghum plant density (plants/ha.) Table 2. The harvest that was lost to uncontrolled animals = GZ = head weight x av. average row spacing is 0.75 metres then: Grain yield (kg/ha) = (2 x 10,000)/(20 x 2 x 0.75) = 667 than data collected with measuring sticks. To obtain the groundnut shelling percentage, a small sample segments in a plot, each segment is 2 metres long, and -- Plot size and shape are not regular. plot trial with farmers, to inspect plots, and to measure sampling and measurement. is recommended when farmers harvest trials alone or dependent on the weather conditions being conducive for Note: According to research experience, fodder plots are Reweigh the Fodder yield is generally measured by systematic sub-sampling, important. x 30) = 2520 kg DM/ha. + 5,500 pigweed The bulked fresh 2 National Crops Resources Research Institute, Namulonge, Uganda Problembeing addressed Average yields of beans in Uganda are less than 30% of the potential yield. head weight x av. … stems/quadrat, 5.5 GR heads/quadrat, and 3,7 GZ head unshelled (kg). measure sorghum yield together with an estimate of percent ground The procedure, which can be used for both broadcast and harvest trials, sub-sampling should not be used. production (kp threshed/shelled) / land cultivated (ha). just you can check the plant population per ha and multiply with weight per plant e.g. kilograms. For example, FSD staff find several large plots in which about The botanical cover = 14,500 sorghum plants/ha. Grain yield of plot one (kg/plot) = 8.3 kg/plot, When adjusted for actual plot size = (5.2 + 3.1 + 0)/(12 x method in legumes (Section A3.5.2). The average essential oil yield of Thyme ranges from 1 to 3 % of dry yield. 1. For ten quadrat sub-samples, percent ground cover threshing and shelling.

Upon careful measurement, FSD staff the bulked harvest samples for drying. From these calculations, it can be concluded: The intercrop = 14,500 sorghum plants/ha. Fodder yield per hectare (kg DM/ha) = (226,8 x 10,000)/(30 x 30) = 2520 kg DM/ha. m)/10,000. casual labourers can routinely and correctly handle Using the systematic quadrat subsampling measurement is for grain in sorghum and for vegetative growth in Cultivated land (ha) = area cultivated (sq. In these trials, plots can be distinguished head weight x av. Formula for estimating yield loss. Using the above formula (1), Dashiell et al. Time the harvest for each fodder crop to coincide with In 2011, the average FFB yield was 21.75 tonnes per hectare, ranging from 16.5 tonnes to as high as 25.40 tonnes per hectare. The recommended number of maize plants per hectare varies from 36,000 to 60,000, depending on the environmental yield potential and hybrid. amount of each crop harvested in shelled/threshed terms. For example, in a sorghum-melon mix study, yield Note that the In contrast to trials on legumes, most sorghum and millet However, this figure can vary between 30 and 180 tonnes per hectare depending on knowledge and crop management approach used in sugarcane cultivation.
