RESPONSE OF NITROGEN AND PHOSPHORUS FERTILIZERS EFFICIENCY ON GROWTH AND YIELD ATTRIBUTES OF SOYBEAN (Glycine max L. Merill.)

Abstract

A study was conducted to study the response of inorganic fertilizers, nitrogen, and phosphorus on morphophysiological and yield parameter of soybean, the experiment was laid out in a Randomized Complete Block Design (RCBD) by three replications at Sher-e-Bangla Agricultural University, Dhaka, Bangladesh in 2019. Three levels (0, 25, and 40 kg N ha-1 ) of nitrogen and four levels (0, 18, 36, and 54 kg P ha-1 ) of phosphorus fertilizer used as a treatment for this experiment. Soybean plants responded to the nitrogen and phosphorus fertilizer for the crop growing, and improving yield contributing characters were significantly influenced. Significant effect on plant height, number of branches, seeds plant-1 , number of filled pods plant-1 , the weight of seeds plant-1 , dry weight of the plant, stover weight plant-1 , 1000-seed weight, seeds, and stover yield were observed from the collective application of 25 kg N with 54 kg P ha-1 . Therefore, the combined application of 25 kg nitrogen ha-1 and 54 kg phosphorus ha-1 might have suggested the best possible options to acquire soybean seed yield from a field experiment.
