Impact of different doses of phosphorus application on various attributes and Seed yield of Pea (Pisum sativum L.)

Abstract

This investigation was undertaken with prime objective to find out the effect of various doses of phosphorus application on seed yield of three varieties i.e Rachna, Aparna and Pant Pea-5 of Pea during rabi season 2015-16. Phosphorus fertilizer doses 0, 30, 60, and 90 kg/ha was used. The field experiments were carried out, wherein the influence of the different fertilizer doses was also determined on the plant morphological and growth characters and their ultimate impact on the seed yield. It was found that seed yield is dependent significantly and positively on number of seeds per pod and harvest index in all the three varieties i.e. Rachna, Aparna and Pant Pea-5. Seed yield was also dependent positively and weakly on biological yield (4100 kg/ha). As phosphorus doses have been found to be effective in increasing seed yield (2250 kg/ha) and hence, these fertilizer doses which are cheaper and easily available could be used to achieve better seed yield in Pea.
