Abstract:
In the year 2020-21, an experiment was conducted at JNKVV, Jabalpur, Madhya Pradesh, to evaluate the influence of pruning and weed control measures on wheat production and yield contributing characteristics when cultivated under a 22-year-old Dalbergia sissoo-based Agrisilviculture model. The performance of wheat in an agroforestry system with various pruning regimes such as light, moderate, heavy, and no pruning was compared to that of wheat grown in open settings. Maximum plant height (92.57 cm), number of effective tillers per metre row length (89.48), length of ear head (8.21 cm), grain production (2812.07 kg ha^-1), and straw yield (4449.55 kg ha^-1) were observed under heavy, significantly at par with moderate pruning, while lowest under light and no pruning in the agroforestry system. Heavy, moderate, light, and no pruning treatments reduced wheat grain production by 19 percent, 25 percent, 36 percent, and 39 percent, respectively, as compared to the open condition or solitary wheat cropping. Weed management measures considerably increased wheat production and yield contributing factors compared to control plots where no weed management practises were used.
