EFFECT OF WEED MANAGEMENT AND FERTILIZER LEVELS IN RAINFED COTTON

A field experiment was conducted at the College Farm College of Agriculture Navsari Agricultural University Bharuch Gujarat to evaluate the Effect of weed management and fertilizer levels in rainfed cotton (Gossypium hirsutum L.) Under South Gujarat condition during kharif seasons of 2020-21 and 2021-22.The experiment was designed in a factorial randomized block design encompassing two factors with total ten treatment combinations and three replications. The factors included: Five weed management treatments i.e. Two hand weeding and interculturing at 30 and 60 DAS (W1) Pendimethalin 1.00 kg/ha PE fb hand weeding and interculturing at 60 DAS (W2) Pendimethalin 1.00 kg/ha as PE+ Dhaincha as smother crop harvested and mulched at 50 DAS (W3) Soil solarization with transparent plastic sheet (LDPE 50 μm) for 6 weeks in the month of April and May + one hand weeding at 60 DAS (W4) Unweeded control (W5) and two fertilizer levels i.e. F1: 75% RDF and F2:100% RDF. The experiment was conducted for two consecutive years with same randomization.
