Abstract:

Field experiments were conducted during rabi seasons of 2015 and 2016 at Teaching Farm, College of Agriculture, Extended Campus of BCKV, Burdwan, West Bengalto find out the effect of different establishment techniques and weed management practices in sunflower. The experiment was laid out in split plot design with four replications. Main plot treatment consisted of two establishment methods, viz. E1: Conventional sowing and E2: Micro pot technique. Three weed management methods, viz. W1: pre-emergence application of pendimethalin @1.0 kg/ha followed by hand weeding on 21 days after sowing or transplanting (DAS/DAT), W2: pre-emergence application of butachlor @1.5 kg/ha followed by hand weeding on 21 DAS/DAT and W3: Farmer practice (hand weeding at 21 DAS/DAT) included in the sub plot treatments. Weed spectrum of the experimental field consisted of three groups of weeds like prominent weed species observed in experimental site were grasses: Cynodon dactylon, Dactyloctaneum aegyptium, Digitaria sanguinalis, Eleusine indica, Echinochloa colona etc. Sedge: Cyperus esculentus, Cyperus rotundus, Fimbristylis littoralis etc. Broadleaf: Alternantherasessilis, Commelina benghalensis, Digera arvensis, Eclipta alba etc. It was observed that micropot technique and pre-emergence application of pendimethalin 1.0 kg/ha followed by hand weeding at 21 DAS/DAT can keep the weed density and weed biomass below the economic threshold level and increase the productivity of sunflower.
