Abstract:
Agroforestry is a collective name for land-use systems and technologies where woody perennials (trees, shrubs, palms, bamboos, etc.) are deliberately used on the same land-management units as agricultural crops and/or animals, in some form of spatial arrangement or temporal sequence. A field experiment was conducted at Agricultural Research Farm, BHU, Barkachha, Mirzapur, (U.P.). The experiment consisting of six intercultural techniques treatments was laid out in Randomized Block Design with four replications on sandy loam soil during Kharif season 2019. The treatments were Control (No interculture) (T₁), Rice straw mulch (2 tonnes ha^-1) (T₂), {T₂ + Pre-mergence herbicide (Pendimethalin @ 1.0 kg ha^-1)} (T₃), Hoeing at 15 DAS (T₄), Hoeing at 30 DAS (T₅), Hand weeding @ 20 & 40 DAS (T₆). The Result revealed that the maximum N, P & K content (%) in grain noted with the treatment T₆ (weeding at 20 & 40 DAS). Two hand weeding (T₆) also remarked significantly higher N, P & K uptake by grain over other treatments. The significantly higher nutrient content (%) and uptake (kg ha^-1) in grain & stover, grain yield (920.75 kg ha^-1) and stover yield (1860 kg ha^-1) were also recorded under T₆ treatment.
