In order to estimate yield, you must also integrate kernel weight into the calculation. The problem with this method or any other variant for estimating corn yield prior to harvest, is that you aren’t collecting any physical data which measures kernel weight – limiting the accuracy. Accordingly...
A crop yield forecasting formula calculation unit (30) generates a crop yield forecasting formula on the basis of the correlation between SAR backscattering intensity of widely-scattered sample agricultural fields during the first half growth period and growth features of the paddy rice, such as the...
The calculation formula is shown in Supplementary Section 2. Amongst the various inputs of crop production, we assume that seed consumption is entirely derived from local production, so that the WF of seed consumption is equal to the WF of crop production in 2015. The CF of seed consumption ...
The calculation of NDVI requires the multispectral image from the satellite. The multispectral images contain more than 3 bands which are red, green, blue. The NDVI can be calculated by the simple formula that requires the values of 2 bands red and near infrared. The NDVI value ranges from ...
Conservation tillage can improve soil physical structure and water storage, protect moisture, and increase crop yield. However, the long-term adoption of a single tillage method may have some adverse effects on soil and ecological environment, although crop yields have increased. Through informed alloc...
By using this crop yield forecasting formula, a crop yield calculation unit (34) determines an estimated value for a growth feature of the paddy rice in a target paddy rice field on the basis of the backscattering intensity of the paddy rice field as obtained from an SAR image thereof ...
Studies have shown that precise irrigation based on the growth stage and real-time water stress level in a plant (e.g., soybeans in the case of26) leads to a maximized yield. Due to the indirect measurement, soil moisture sensors are unable to guide the irrigation system to precisely ...
It is calculated as the ratio between the crop water requirement and the actual crop yield (D’Odorico et al., 2019; Mekonnen & Hoekstra, 2011). The crop water requirement (CWR) quantifies the amount of water required by crops along the cropping season, namely the amount of water lost...
the substrate treatment B fits the growth of tomato.There is no significant difference between treatment B and CK on plant height,stem diameter,biomass and yield of tomato.Therefore treatment B is thought to be the best substitute organic substrate formula to CK which is mainly made up of peat...
The crop yield estimate using the standard formula would be 30 x 24 x 35 x 0.04356 = 1,097 kg/acre if a wheat producer counted 30 heads per foot squared and each head contained 24 seeds, assuming a 1,000-kernel weight of 35 grams. The estimated yield would be 40 bu/acre (1097/27....
