    Experiences in coconut based farming systems in India
    (2007-02) Gopalasundaram, P.; Thomas Varghese, P.; Hegde, M.R.; Nair, M.G.K.; Das, P.K.
    A sole crop of coconut, at the recommended spacing of 7S x 7S m does not fully utilise the available soil and air space and incident solar radiation. Crops identified as compatible ones with coconut include many tuber crops (cassava, elephant foot yam, yams, colocasia), rhizome-spices (ginger, turmeric), pulses (cowpea), oilseeds (groundnut, soybean), upland rice, fruit crops (banana, pineapple) and vegetables among the annuals and cocoa, black pepper, clove and nutmeg among perennials. Many intensive crop combinations which involve different annuals and perennials over a period of time such as multistoreyed cropping system and high density multispecies crop models have also been developed. Mixed farming systems, which integrate other enterprises like dairying and sericulture provide higher employment generation and enhanced net income. Among the annua! crops, elephant foot yam and ginger are the most profitable. The additional employment generated ranged from 76 to 900 mandays/ha/year in different systems.

    Performance of four Varieties of Black Pepper (Piper Nigrum L.) as Mixed Crop with Arecanut (Areca Catechu L.) Under Different Planting Densities
    (2007-02) Abdul Khader, K.B.; Nair, M.G.K.; Yadukumar, N.
    A study was conducted to Investigate the performance of four varieties of pepper as a mixed crop in arecanut garden with six planting densities. The results revealed that in arecanut garden with a recommended spacing of 2.7 x 2.7 m, 43 per cent of sunlight is available to other component crops. Pepper as a mixed crop did not influence the yield of arecanut and Karimunda followed by Panniyur-I were found to be suitable pepper varieties in arecanut garden. The highest yield of pepperwas observed with a spacing of 1.8 x 2.7m with Karimunda variety. The results also indicated that pepper is a profitable mixed crop in arecanut garden.
