ABSTRACT

A field experiment was conducted during Rabi season 2018-2019 at Doon (P.G.) College of Agriculture Science and Technology, Selaqui, Dehradun (Uttarakhand) using four herbicides, with Hand Weeding applied for effectively controlling of weeds, their effect on yield and production economics on Chickpea (Cicer arietinum L.) variety used ‘Pant Gram-186’. The dominant weed species were among monocot weeds were Phalaris minor, Cynodon dactylon, Brachiaria mutica, and Cyperus rotundus, and the dicot weed species Parthenium hysterophorus, Medicago denticulate, Convolvulus arvensis, Melilotus indica, Chenopodium album, were observed during the growing season. Weed dry weight of monocot and dicot weed was the lowest observed in hand weeding carried out 30 and 60 days after sowing. Higher Weed control efficiency up to (93.11 %) was recorded by Hand weeding at 30 and 60 days after sowing.  This treatment too recorded greater yield attributes and seed and Stover yield (1811 kg/ha and 2247 kg/ha) and maximum net monetary return (Rs 35016) and Benefit: Cost ratio and 1.88.
