Abstract

Wheat crop cv WH 147 was grown under twelve important MPTs (Acacia nilotica, Acacia cupressiformis, Casuarina equisetifolia, Madhuca latifolia, Melia azedarach, Leucaena leucocephala, Dalbergia sissoo, Albizia lebbeck, Syzygium cumini, Eucalyptus tereticornis, Emblica officinalis and Hardwickia binata) to know the effect of transmitted Photosynthetic Active Radiation (PAR) through the tree canopies on the grain yield of wheat. The highest light transmission of 58.7% were observed on M. latifolia followed by 58.1, 55.3 and 51.7% respectively in S. cumini, H. binata and E. officinalis and least light transmission of 34.2% was observed in A. nilotica under agroforestry situation. The light transmission ratio after pruning were much higher than those of the before pruning both under agroforestry as well as under control system. Light transmission ratio in general were higher under wider tree spacing in all the MPTs compared to lower tree spacing in association with crops as well as under control. There was no significant difference in wheat yield under the different MPT canopies in first year, however, in the second year onwards the production of wheat grain was drastically reduced under the tree canopies with a highest grain yield of 26.84 q/ha under Madhuca latifolia. The status of PAR transmitted was also correlated with the grain yield of wheat.
