The experiment was carried out at Akshayvat farm, Village- Arai, Block- Karchana, Allahabad during the year 2016- 2017. In agrisilviculture system, canopy management like pruning is an essential silvicultural management practice for reducing both above and below ground competition with associated crop. The experiment consists of five pruning intensities viz: no pruning, 20% pruning, 40% pruning, 60% pruning, 80% pruning and one open condition (no tree crop only) in main plot and three levels of fertilizer doses and seed rate viz; F1- recommended dose of fertilizer and seed rate, F2- 25% more nitrogen then recommended dose of fertilizer and F3- 25 % more seed rate than recommended dose of seed in sub plot under three replications. The results revealed that wheat under open condition recorded significantly higher germination percentage (), plant height (),number of tillers (), fresh wt. (), dry wt.( gm), grain yield ( q ha-1 ), fixed carbon () and carbon sequestration ( t ha-1 ) as compared to no pruning. In different levels of fertilizer doses and seed rate maximum plant height (), number of tillers (), fresh wt. (), dry wt.( gm), grain yield ( q ha-1 ) and carbon sequestration ( t ha-1 ) was significantly higher under F2 (more nitrogen than recommended dose) as compared to F1 treatment. At age of 11 years, Dalbergia sissoo in 20% pruning gave higher tree height ( m), basal area ( m2 ), volume ( m3 tree-1 ), and carbon sequestration ( kg tree-1 ) as compared to other treatments. In agronomical management practices, 25% more nitrogen then recommended dose (F2) recorded significantly higher stand biomass ( kg tree-1 ) over other treatments. | Growth performance, productivity and Carbon sequestration of wheat (Triticum assstivum)- Shisham (Dalbergia sissoo) based agri-silviculture system with especial reference to tree pruning intensities and agronomic practices
