Abstract:
Water is essential for all living beings but in the present context water availability is decrease in rapid way. Along with this per capita land availability is also decreasing due to varies developmental activities. Now it is the time to switch on to the research that increases more biomass per unit drop of water. Our study was carried out during 2015-16 in combination of Dalbergia sissoo and wheat agroforestry system in rabi season. It is expressed in terms in terms of equivalent grain production kg per m³ or kg per cm depth of water used. Wheat equivalent water productivity (WEWP) of 17 year Dalbergia sissoo-wheat agrisilviculture system under four pruning treatment was evaluated in central India. Four treatments viz. no pruning 0% (P₀), light pruning 25% (P₂₅), moderate pruning 50% (P₅₀) and high pruning 75% (P₇₅) were taken. Our study reveals that Wheat grain yield was significantly superior in P₇₅ (3066 kg ha^-1) to the other treatments. Grain yield of P₅₀ (2654 kg ha^-1) was significantly superior to P₂₅ (2136 kg ha^-1) and P₀ (1826 kg ha^-1). The water productivity (kg ha^-1 cm^-1) of agroforestry system in rabi season in response to different pruning intensities (P₀, P₂₅, P₅₀ and P₇₅) shows that among the different pruning intensities, the water productivity of P₂₅ is highest (255 kg ha^-1 cm^-1) followed by P₅₀ (249 kg ha^-1 cm^-1), P₇₅ (189 kg ha^-1 cm^-1) and P₀ (196 kg ha^-1 cm^-1).
