The Effect of Plant Density, Zinc Added to Phosphorus Fertilizer Sources and Location on Selected Yield Parameters of Soybean

Background: Soybean [Glycine max (L.) Merrill] is an annual herbaceous leguminous grain crop which cultivated mainly for its oil and protein. The objective of the study was to determine effects plant density zinc added phosphorus fertilizer sources on soybean yield performance under different environmental conditions. Methods: A field trial executed in two sites during 2018/19 2019/20 summer planting seasons. experimental design involved a 2 × 5 factorial fitted into randomized complete block (RCBD) with four replications. experiment consisted densities, lower 66 666 plants/ha higher 111 plants/ha. five types treatments were single superphosphate, monoammonium phosphate, sulphate phosphate control. Result: results showed that has significant effect (P less than 0.05) number pods per biomass yield. planted conditions produced significantly larger both seasons, whereas resulted season. It observed treated had seed mass.
