Abstract/Description: | A field experiment was conducted during rabi season of 2014- 15 at Jabalpur, to study the effect of sowing date on weed infestation and yield of wheat varieties under different irrigation schedules. The results indicated that the crop sown on 27th November exhibit significantly highest grain (4.85 t/ ha) and straw (6.99 t/ha) yield as compared to delayed sowing. Similarly wheat cv. GW 366 under four irrigations at critical stages i.e. CRI, flowering, late jointing and milking recorded highest grain and straw yield over rest of the treatments under study. The lowest total weed density (29.11/ m2) and biomass (3.46 g/m2) was obtained in delayed sowing (27th December). Among varieties MP 1202 recorded lowest total weed density (41.10/m2) and biomass (8.57 g/m2) as compared to GW 366. While low frequency of irrigation i.e. two irrigation at CRI and flowering produced lowest weed density and biomass. Amongst the different weed species Melilotus indica and Chenopodium album are the predominant broad leaved weed species observed through out the crop growth of wheat crop. Weed density and biomass did not reveal any significant difference irrespective of varieties and irrigations schedules indicating sowing dates had prime importance in respect of density and biomass. |
