Performance of chickpea (Cicer arietinum L.) under varied seed rate, geometry and weed management conditions

An experiment was conducted during winter (rabi) seasons of 2005-06 and 2006-07 to study the performance of weeds on chickpea (Cicer arietinum L.) to various seed rate (75,100 and 125 kg ha¹) row spacing (30 and 45 cm) and weed management practices (weed check, two hand weeding at 30 and 45 DAS. Per-emergence application of pendimethalin @ 0.5 kg a.i ha¹ within hand weeding at 30 DAS and application row spacing 45 cm and pendimethalin @ 250gm a.i. ha¹ with one hand weeding at 30 DAS). The combination of seed rate @ 100 kg ha¹ row spacing 45 cm and pendimethalin @ 0.5 kg a.i. ha¹+ one hand weeding at 30 DAS reduced total weed provide the higher grain yield with higher net income and B:C ratio.
