Evaluation of different herbicides on growth and yield of chickpea (Cicer arietinum L.) under Uttarakhand conditions.

Abstract

A field experiment was conducted during rabi season of 2017-2018 at Dehradun (Uttarakhand) with four herbicides, integrated with HW to evaluate the effectiveness of the herbicides on controlling weeds, their impacts on return and production economics on chickpea (Cicer arietinum L.) variety 'Pant Gram-186'. The dominant weed species among monocot weeds were Phalaris minor, Cynodon dactylon, Brachiaria mutica and Cyperus rotundus and among the dicot weed species Chenopodium album, Medicago denticulate, Convolvulas arvensis, Melilotus indica, Parthenium hysterophorus were detected during growing season. Weed dry weight of moncot and dicot weed was the lowest by hand weeding carried out 25 and 45 DAS. Extreme weed control efficiency was noticed with interculturing HW on 25 and 45 DAS. This treatment also recorded advanced yield attributes and seed and stover yield (1761 kg ha-1 and 2245 kg ha-1) and maximum net monetary returns and benefit: cost ratio (' 34076 and 1.88, respectively).
