PHOSPHORUS FERTILIZER AND CORN YIELD
Keywords:
corn, fertilizer, phosphorus, orthophosphate, crop, yield.Abstract
The increase in corn yield is directly related to mineral fertilizers, including phosphorus. Increasing the rates of phosphorus fertilizers in the absence of phosphorus soils leads to an increase in the amount of feed due to an increase in feed units. An increase in the phosphorus norm to 100 kg/ha P2O5 ensured an increase in the indicated norms of indicators by 6.4-8.5 and 3.3-3.0%, respectively, when applying 140 kg/ha P2O5 - by 10.6-12.1 and 5.4-5.2%, and when applying 180 kg/ha P2O5 - by 12.8-16.1 and 6.5-6.3%.
