Effect of Phosphorus and Zinc on Growth and Yield of Lentil (Lens culinaris L.)

Abstract

A field experiment was conducted during Winter season of 2022 at Crop Research Farm (CRF). Department of Agronomy, SHUATS, Prayagraj (UP) to investigate the effect of phosphorus and zinc levels on growth and yield of lentil. The treatments consist of three phosphorus doses viz., 20, 30, 50 kg/ha and three foliar zinc doses i.e., 0.25%, 0.5%, 0.75% whose effect is observed on Lentil (var. PL 406). The experiment was laid out in RBD with Ten treatments replicated thrice. The treatment with application of Phosphorous 50 Kg/ha + Zinc 0.75% recorded significantly higher plant height (45.28 cm) and plant dry weight (12.15 g), number of pods per plant (123.67), number of seeds per pod (1.80), test weight (24.77 g), seed yield (1.72 t/ha) and straw yield (3.36 t/ha) compared to other treatment combinations. It is concluded that Phosphorous 50 Kg/ha + Zinc 0.75% execute better growth parameters, yield attributes and higher seed yield in lentil crop under eastern Uttar Pradesh conditions.
