Abstract

An experiment was laid out in randomized complete block design (factorial experiment) during the winter (rabi) seasons of 2020–21 and 2021–22 at Instructional Farm, Rajasthan College of Agriculture, MPUAT, Udaipur (Rajasthan) to study the effect of P (30, 40 and 50 kg P2 O5 /ha), S (15, 20 and 25 kg S/ha) and zinc (control and foliar spray of 0.5% ZnSO4 ) on yield nutrient content and nutrients uptake in lentil. Seed yield increased to a maximum of 9.35% following P application, 9.38% after S application and 4.71% after Zn application. Corresponding increase in haulm yield was 12.90%, 10.64% and 7.30% respectively. Application of P, S and Zn improved protein content in seed as well as in haulms and increasing application level of both P and S maintained the increasing trend in protein content. Application of P, S and Zn increased both the content and the uptake of N, P, K, S and Zn both in seeds and in haulms. In most instances these changes were statistically significant.
