Abstract:
A field experiment was conducted during the summer season of 2018 at Agricultural farm of Palli Siksha Bhavana (Institute of Agriculture), Visva Bharati, Sriniketan, Birbhum, West Bengal to the “Studies on Efficacy of Flumioxazin in summer Groundnut (Arachis hypogaea L.)”. The experiment comprising of eight treatments was laid out in a randomized block design with three replications. From the experimental findings it was revealed that Groundnut was infested with three categories of weeds viz. grass, sedge and broadleaf. Digitaria sanguinalis, Cynodon dactylon among the grasses Cyperus rotundus among the sedges and Alternanthera philloxeroides among the broadleaved weeds were present as predominant weeds. Among the herbicides tested, lower values of weed index, weed density, weed dry weight and highest weed control efficiency was found with the pre-emergence application of Flumioxazin 50% SL 150 g a.i ha-1 at 1 DAS which show better performed than Imazethapyr 10 SL 100 g a.i ha-1 at 1 DAS and Pendimethalin 30% EC 750 g a.i ha-1 1 DAS in case of grasses, sedges and broadleaves but was at par with Flumioxazin 50% SL 125 g a.i ha-1 at 1 DAS. Application of Flumioxazin 50% SL 150 g a.i ha-1 at 1 DAS and Flumioxazin 50% SL 125 g a.i ha-1 at 1 DAS were equally efficient in increasing the grain yield, straw yield and gross returns than untreated control but net returns (₹ 109161 ha-1) and benefit-cost ratio (3.22) was obtained maximum only with Flumioxazin 50% SL 125 g a.i ha-1 at 1 DAS. Thus, Flumioxazin 50% SL 125 g a.i ha-1 at 1 DAS appeared as promising for managing broad-spectrum weeds and higher productivity of summer Groundnut in red and lateritic soils of West Bengal.
