Effect of Sowing Dates and Weed Management on Growth and Yield of Chickpea in Indo-Gangetic Plains

Effect of Sowing Dates and Weed Management on Growth and Yield of Chickpea in Indo-Gangetic Plains A field experiment was conducted during rabi season of 2009–2010 to find out the suitable date of sowing and weed control systems for getting maximum chickpea grain yield, at the Agricultural Research Farm of the Institute of Agricultural Sciences, Banaras Hindu University, Varanasi, UP. The treatments consisted of three dates of sowing viz. November 10 (S1), November 25 (S2) and December 5 (S3) with eight weed management system viz. Weedy check (W1), Weed free check at 30 and 60 DAS (W2), Pendimethalin @ 1 kg/ha as pre-emergence (W3), Quizalofop @ 50 g/ha as post-emergence (W4), Imazethapyr @ 37.5 g/ha as post-emergence (W5), Pendimethalin fb Quizalofop (W6), Pendimethalin fb Imazethapyr (W7) and Pendimethalin + Mechanical (W8). The results showed that the chickpea sowing on November 25 (S2) produced taller plants with higher number of root nodules, root length, dry matter, pods/plant, seeds/pod, seed index which resulted in higher grain and straw yield. Sowing S2 produced higher grain and straw yield (1,475 and 3,354 kg/ha) than early (S1) and delay sowing (S3) (1,307 and 1,114 kg/ha) which was increased by 12.85 and 32.40 % more, over the S1 and S3 sowing dates. Among weed control systems, W8 gave better control of weeds and increased grain yield of chickpea by 62.81 % over the control (W1) and proved significantly superior on rest of the treatments followed by W6 (59.03 %). http://www.deepdyve.com/assets/images/DeepDyve-Logo-lg.png Proceedings of the National Academy of Sciences, India Section B: Biological Sciences Springer Journals

Abstract

A field experiment was conducted during rabi season of 2009–2010 to find out the suitable date of sowing and weed control systems for getting maximum chickpea grain yield, at the Agricultural Research Farm of the Institute of Agricultural Sciences, Banaras Hindu University, Varanasi, UP. The treatments consisted of three dates of sowing viz. November 10 (S1), November 25 (S2) and December 5 (S3) with eight weed management system viz. Weedy check (W1), Weed free check at 30 and 60 DAS (W2), Pendimethalin @ 1 kg/ha as pre-emergence (W3), Quizalofop @ 50 g/ha as post-emergence (W4), Imazethapyr @ 37.5 g/ha as post-emergence (W5), Pendimethalin fb Quizalofop (W6), Pendimethalin fb Imazethapyr (W7) and Pendimethalin + Mechanical (W8). The results showed that the chickpea sowing on November 25 (S2) produced taller plants with higher number of root nodules, root length, dry matter, pods/plant, seeds/pod, seed index which resulted in higher grain and straw yield. Sowing S2 produced higher grain and straw yield (1,475 and 3,354 kg/ha) than early (S1) and delay sowing (S3) (1,307 and 1,114 kg/ha) which was increased by 12.85 and 32.40 % more, over the S1 and S3 sowing dates. Among weed control systems, W8 gave better control of weeds and increased grain yield of chickpea by 62.81 % over the control (W1) and proved significantly superior on rest of the treatments followed by W6 (59.03 %).
