บทคัดย่อ (EN): Traditional small holdings are characterized by relatively stable but low yields. Intercropping mature rubber with suitable crops will provide the small farmers with a diversity of enterprise and a degree of stability in income when large price fluctuations occur. A field experiment was conducted in a mature rubber plantation of clone RRII 105 aged 10 years in a small holding representing the central rubber growing tract of India to evaluate the performance of coffee and cocoa as inercrops and to find out the nutrient requirement of the system. The treatments comprised of two varieties of coffee viz., robusta and C x R and cocoa inter planted in rubber in combination with two doses of fertilizers viz., 100 and 50 per cent of the recommended dose for coffee and cocoa. Coffee and cocoa were established well and started yielding by third year. The growth and yield of rubber did not vary significantly among the treatments indicating that intercropping of perennial crops like coffee and cocoa did not adversely affect the performance of rubber. There was not much variation in the total yield between different varieties of coffee. However, the per plant yield of coffee was only 36 per cent of that under monoculture whereas the intercrop yield of cocoa was around 60 per cent of that of monoculture. Though competition existed between the component crops for above ground resources, mainly radiation capture, there was no dearth of below ground resources and the soil fertility was improved under the intercropped situation compared to monoculture rubber. As there was no response to additional fertilizer dose either in terms of growth or yield, the data suggested that the nutrient requirement of the intercropping system was less compared to sole crop and the fertilizer dose for intercrops could be reduced to half without affecting the soil and leaf nutrient status. It is evident from present study that cocoa can be successfully cultivated as an intercrop in mature rubber. Therefore, the overall productivity and profitability of rubber plantations can be increased with minimal investment by raising cocoa as intercrop.
