520 _aRubber growers in South East Asian countries are facing acute crisis due to the price volatility, sharp increase in cost of cultivation, increasing drought and declining soil fertility. With an objective to generate additional income and improve smallholder welafare by integrating diverse crops in rubber ecosystem, three experiments were conducted in Rubber Research Institute of India during 2001-2014 period. In one experiment, coffee, vanilla on Glyricidia standards, Garcinia and nutmeg were cultivated along with rubber without altering the planting design and density of rubber trees. Growth of rubber was significantly higher under mixed planting and yield was not influenced. Soil moisture status during summer and microbial population were higher in mixed planting system and soil nutrient status was maintained. Yield of all the intercrops was good during initial years. As the shade from rubber canopy intensified, Garcinia perished but vanilla and coffee continued to yield reasonably well. In another experiment, nine shade tolerant medicinal plants were evaluated in mature rubber plantation. All the medicinal plants established well and produced reasonable biomass, but the performance of Strobilanthes cuspida and Alpinia calcarata were comparatively better. In another study, it was observed that short duration vegetables like amaranthus and salad cucumber can be cultivated during the annual leaf shedding period in mature rubber plantations to meet part of the household requirement. The results showed that diverse crops can be integrated with rubber without any adverse effect on growth and yield of rubber. Crop diversification generated additional income, mitigated drought and sustained soil fertility.
