Abstract: The present investigation was taken up with 17 years old agrisilviculture system (Dalbergia sissoo + wheat) during Rabi season 2015-16 under AICRP on Agroforestry, Department of Forestry, JNKVV, Jabalpur (M.P.). Planting space of Dalbergia sissoo was 5×5 m. The treatment combination involved four pruning treatments and one open (without tree) in main plot and three levels of fertilizer and seed rate of wheat variety GW-173 in sub plot in split plot design.
Wheat under open condition recorded significantly higher fresh wt., dry wt., fixed carbon and carbon sequestration as compared to no pruning which recorded the lowest values. Fresh wt, dry wt., fixed carbon and carbon sequestration was significantly higher under T2 (T1 + 25% more nitrogen than recommended dose) as compared to T1 treatment.25% pruning recorded higher DBH, tree volume, above ground biomass, carbon sequestration, carbon-di-oxide sequestrated by tree and carbon-di-oxide sequestrated by the tree per year and it was minimum in 75% pruned trees.
Combination of Dalbergia sissoo + wheat sown under 25% pruning recorded significantly higher carbon sequestration potential as compared to other pruning treatments.
