摘要

An experiment was initiated during 2004 at Regional Research Station (Red & Laterite Zone), Bidhan Chandra Krishi Viswavidyalaya, Jhargram, West Bengal to standardize fruit-based agroforestry model for rainfed upland under red &' laterite tract of humid & sub-humid zone. The experiment involves silvicultural species (Gmelina arborea), fruit crops (sweet orange and guava) and arable crops (cowpea, groundnut, blackgram and bottlegourd). Fruit plants were planted at a spacing of 10x10 m. Seedlings of tree species were planted in between two fruit crops. In this way, two hectares of uplands have been developed with fruit-based agroforestry system. Both tree species and fruit plants were planted in the 3rd week of June, 2004. Broad spacing of tree and fruit crops gives an opportunity to grow number of intercrops for first few years. Four arable crops viz., cowpea, groundnut, blackgram and bottlegourd were grown under both G. arborea+sweet orange and G. arborea+guava-based agroforestry system during kharif seasons of 2005, 2006 and 2007. Experimental results revealed that tree height, bole height, diameter at breast height and volume yield of G. arborea were increased with the increasing age of tree. On an average, yield (mean of three years) of cowpea, groundnut, blackgram and bottlegourd was 1.94 & 1.86, 0.84 & 0.80, 0.72 & 0.66 and 12.92 & 12.56 t/ha when intercropped under G. arborea+sweet orange and G. arborea+guava-based agroforestry system, respectively. All the four arable crops gave maximum net return under G. arborea+sweet orange-based agroforestry system. So far as different agroforestry systems are concerned, G. arborea+sweet orange+bottle gourd model gave maximum total outturn (Rs. 89,504.00) closely followed by G. arborea+guava+bottlegourd model (Rs. 87,446.00). Such sort of venture will be of multifarious utility to the farmers because it not only provides fuel wood, timber, fruits and crop produce but also increases cropping intensity, maximizes the combined income from the interrelated crop-tree-fruits-people complex over the year, enriches the soil health and last but not the least ensures ecological balance.
