Weed Dynamics, Growth and Yield of Wheat Crop as Influenced by Different Tillage and Herbicide Management under Rice-Wheat Cropping System
Abstract
A field experiment on sandy loam was conducted during rabi 2004-05 and 2005-06 at the Research Farm of the Janta Vedic (P.G.) College, Baraut, District–Baghpat (U.P.) to ascertain the relationship among the seed-bed preparation, nutrient and weed management of wheat (Triticum aestivum L.) under six tillage practices (Strip till-drill (STD), Zero tillage (ZT), Surface seeding (SS), Reduced tillage (RT), Conventional line sowing (CLS) and Furrow irrigated raised bed planting system (FIRBS) in main plots and three weed control measures (Metribuzin (Sencor) @ 250 g/ha, Sulfosulfuron (Leader) @ 33.3 g/ha, Weedy check) in sub plots with three replicates. Herbicides was applied at 30-35 days after sowing as a post, emergence. The amount of each herbicides per plot was measured and diluted to desired concentration. Furrow irrigated raised bed planting recorded taller plant, higher dry matter accumulation while, maximum leaf area index was recorded under reduced tillage followed by conventional line sowing and FIRBS. In respect of CGR and NAR furrow irrigated raised bed system estimated highest value of these indices followed by conventional line sowing at 30-60 and 60-90 DAS. Furrow irrigated raised bed planting system (FIRBS) recorded higher grain and straw yield significantly higher over the other tillage management. Conventional line sowing (CLS) also recorded significantly higher yield and yield attributes as compared to other tillage practices. The herbicide application significantly increased the grain and biomass yield due to reduction in weed density and weed dry weight. The highest yield and yield attributes was obtained with the application of Sulfosulfuron @ 33.3 g/ha followed by Metribuzin @ 250 g/ha in present investigation.
