Coconut Based Farming Systems For Increasing Productivity And Profitability Of Smallholder Coconut Plantation In Sri Lanka
Coconut is commercially cultivated in Asia and Pacific countries predominantly as a small holder crop, which is associated with lives of millions of coconut growers. Income and productivity of coconut directly affect on livelihood of these people. Generally, coconut lands are maintained as monoculture farming and recognized as an inefficient land use system. Coconut palms are generally spaced 8 m x 8 m apart, thereby 75% of the area remains below its production potential from the age of 20 years or so. Unlike other crops such as tea, and rubber, opportunities to grow inter crops in coconut plantations are enormous. Coconut based farming systems (CBFS) are well established and attractive to maximize land use efficiency, increase productivity and to optimize profitability over to monoculture coconut farming. Hence, monoculture to crop diversification is a must for income generation for all levels of coconut growers. Intercropping, multiple cropping, mixed cropping, alley cropping and mixed farm ing are the main systems in CBFS. Any one of these intensive well designed farm ing systems under good management practices would not affected coconut yield. Many coconut + intercrops + animal systems have shown complimentary effects and benefits on coconut. Increase soil fertility, improvement of coconut palm nutrients, creation of favourable micro-climate and increase productivity of coconut lands are discussed in detail. Coconut lands offer ample opportunities to grow large number of crops, rearing animals and combination of those including agroforestry systems. In CBFS, differences within a country, region to region are observed. Hence, a common approach is important to promote CBFS as a viable farming system to increase productivity of coconut cultivation.
