Effect of phosphorus and zinc on yield of lentil

Abstract

Fertilization of lentil (Lens culinaris) is one of the most crucial management technique which affects growth and yield. Therefore the present research was designed to investigate the response of lentil to various phosphorus and zinc levels at Agronomy Research Farm the University of Agriculture, Peshawar during rabi season 2015. The experiment was laid out in randomized complete block design (RCBD) having three replications.Five doses of phosphorus (40, 60, 80,100, and 120 kg ha^-1) and four levels of zinc (3, 6, 9, and 12 kg ha^-1) along with one control (No P and Zn) was used in the experiment. Number of pods plant^-1, thousand grains weight, grain yield and seed recovery percentage was significantly influenced by different doses of both phosphorus and zinc. More pods plant^-1(118) and (122), thousand grain weight (30 g) and (29.6 g), grain yield (2021.3 kg ha^-1) and (2047.5 kg ha^-1) and maximum seed recovery of 69 % were noted from the plots received 100 and 120 kg P ha^-1 respectively. Similarly the application of zinc at 9 kg ha^-1produced morepods plant^-1 (117) and grain yield (1846 kg ha^-1). Statistically similar results were found in plots received 9 and 12 kg Zn ha^-1regarding thousand grain weights (30.6 g and 29.4 g) and seeds recovery percentage (68 %). The above all experimental results concluded that phosphorus and zinc should be used at the rates of 100 kg ha^-1 and 9 kg ha^-1 for the growth and yield of lentil.
