Abstract:
Effect of “Integrated Weed Management in rabi pop corn (Zea mays L. var. everta) under South Gujarat condition” were evaluated in College Farm, Navsari Agricultural University, Navsari (Gujarat) on species wise weed count (per m2), dry weight of weed at harvest (kg ha-1), Weed Control Efficiency (%), Weed Index (%), grain and stover yield (kg ha-1) in rabi pop corn during 2017-18. The experimental soil was clayey in texture, low in available nitrogen (164 kg ha-1), medium in available phosphorus (42 kg ha-1) and high in available potash (315 kg ha-1). Results revealed that the significantly minimum number of monocot (Cynodon dactylon L., Sorghum helepense L., Dactyloctenium aegyptium, Echinochloa colona L. and Brachiaria ramose L.), dicot (Euphorbia hirta L., Chenopodium album L., Digera arvensis Forsk, Physalis minima L., Phyllanthus niruri L., Amaranthus viridis L., Alternanthera sessilis L. and Portulaca oleracea L.), sedge weed (Cyperus rotundus L.), dry weight (148.52 kg ha-1) of weeds at harvest, weed index (1.57%) and highest weed control efficiency (36.30%) were observed under the weed control through treatment T6 fb treatment T5 While, significantly the maximum monocot, dicot, sedge weeds, dry weight (233.17 kg ha-1) of weeds at harvest, weed index (58.17%) and lowest weed control efficiency (0) were recorded under the treatment T10 (control), at 30 DAS, 60 DAS and harvest. Significantly greater grain yield and stover yield (3748 and 7898 kg ha-1, respectively) were registered with treatment T9 but it is statistically at par with treatments of T6, T5 and T4.
