Performance of Various Chemicals Weed Management in Chickpea an Irrigated Environment

Abstract

Chickpea is additional sensitive to weed competition than other crops. During early stages of crop growth competition is more severe because of slow growth rate and leaf area development. Weeds have been blamed for losses in India that range from 40 to 90 percent. Thus, adopting an effective weed management strategy is the only way to significantly increase chickpea yield. The experiment was conducted during Rabi season of 2011-12 at Agronomy Research Farm of NDUA&T, Kumarganj, Ayodhya, Uttar Pradesh. The experiment was laid out in randomized block design with fourteen weed management treatments and replicated in thrice. According to the findings, weed management methods significantly affect the number of nodules, nutrient (N, P, K) uptake, yields, and economics of chickpea over weedy check at growth stage.  Maximum yield (1.72 t ha-1) and nutrient uptake (N- 63.60, P- 9.09 and K- 74.39 kg ha -1) by chickpea were recorded in weed free treatment but maximum nitrogen, phosphorous and potassium (23.22, 2.68 and 50.42 kg ha -1) uptake by weed were obtained in weedy check treatment and lowest in weed free treatment.
