Influence of integrated weed management practices on weed dynamics, growth and yield of chickpea (Cicer arietinum L.)

Abstract

A field experiment was conducted during Rabi season of 2017-18 at the Campus for Agricultural Research and Advanced Studies Dhablan of the G.S.S.D.G.S. Khalsa College Patiala, Punjab. To find out most suitable integrated weed management practices for control of weeds in chickpea under irrigated condition of Punjab. Integrated weed management significantly influenced the weed dynamics, growth and yield of chickpea crop. Weed parameter like total weed population (m-2) and weed dry weight (g) m-2, except weed control efficiency (%) was recorded significantly minimum in treatment T2 (Weed free) which was followed by treatment T4 (Two hand weeding at 25 and 45 DAS) and T6 (Pendimethalin @ 750g ha-1 fb one hand weeding at 25 DAS). All the growth parameters (plant height (cm), number of branches plant-1 and dry weight (g) plant-1) and yield attributes (number of pods plant-1, number of seeds pod-1, test weight (g) and seed yield (q ha-1 were significantly higher in treatment T2 (Weed free) which was followed by treatment T4 (Two hand weeding at 25 and 45 DAS) and T6 (Pendimethalin @ 750g ha-1 fb one hand weeding at 25 DAS).
