Effect of Sowing Methods and Weed Management Practiced on Growth, Yield, Weed Flora and Nutrient Uptake on Late Sown Chickpea

Abstract

Chickpea is highly sensitive crop to weed competition as early stage of growth. In the light of fragmental information available on the response of application of sequential application of herbicides under different sowing methods, a field experiment was conducted during winter season of 2013–14 to 2015–16. Results revealed that chickpea sowing in reduced tillage performed better and produced higher number of pods per plant, seed yield, protein yield and nutrient uptake over conventional tillage. In weed management treatment, sequential application of pendimethalin@0.75 kg a.i./ha pre-emergence followed by imezethapyr @40g a.i./ha post-emergence improve the crop growth and produced higher seed yield (1515 kg/ha), protein yield and nutrient uptake. Weed density and weed dry weight of different species were recorded minimum under reduced tillage at both 30 and 60 days after sowing. Application of pendimethalin @0.75kg a.i./ha pre-emergence followed by imezethapyr @40g a.i./ha post-emergence reduced theweed density and weed dry weight over other treatments and recorded minimum. Weed control efficiency recorded higher with conventional tillage (70.04%) and closely followed by reduced tillage (70.81%). Pendimethalin@0.75kg a.i./ha pre emergence fbimazethapyr @ 40g a.i./ha post-emergence recorded highest weed control efficiency (92.93%).
