Effect of seed rate and weed-management practice on nodulation and yield of chickpea (Cicer anetinum)

Abstract

A field trial was conducted during .the kgka of available N, P and K respectively, winter season of 1987-88 at Faizabad, to with pH 8.1. Chickpea Type 3 was sown in study the effect of 3 seed rates (75, 100 and rows, 45 cm apart. A uniform basal dose of 125 kglha) and 4 weed-management prac- 100 kglha as diammonium phosphate was tices (unweeded check, hand-weeding twice applied in furrows. The irrigation was given at .25 and 45 days after sowing, fluchloralin at 60 days after sowing.
