Abstract:
Department of Forestry, Jawaharlal Nehru Krishi Vishwa Vidyalaya, Jabalpur, Madhya Pradesh to evaluate the effect of different agroforestry systems on productivity of wheat with respect to insect pest. Result revealed that the performance of wheat varieties under different agroforestry system such as Jatropha+wheat, Guava+wheat, Acacia nilotica+wheat was compared to that of wheat grown in open condition (sole wheat crop). The highest number of plant population per m row length (41.08), Height of plant (97.64 cm), number of tillers per m row length (65.26) and highest length of spike (10.41 cm), Grain yield (3795 kg ha^-1), Straw yield (4759 kg ha^-1) and Biological yield (8554 kg ha^-1) was recorded under open condition (sole wheat) and significantly higher than that under Jatropha+wheat, Guava+wheat, and Acacia nilotica+wheat. However among the agroforestry system maximum plant population per m row length (38.20), Height of plant (96.44 cm), number of tillers per m row length (63.99) and highest length of spike (9.04 cm), Grain yield (3579 kg ha^-1), Straw yield (4546 kg ha^-1) and Biological yield (8125 kg ha^-1) recorded under Jatropha+wheat based system followed by Guava+wheat and Acacia nilotica+wheat based agroforestry system. In which wheat variety JW-3382 response maximum plant population per m row length (38.91), Height of plant (92.93 cm), number of tillers per m row length 64.02. and length of spike (9.50 cm), Grain yield (3451 kg ha^-1), Straw yield (4428 kg ha^-1) and Biological yield (7879 kg ha^-1) under Jatropha based agroforestry system followed by JW-3288, JW-3211 and GW-322 wheat variety.
