| dc.description.abstract | Root (wilt) disease, which is debilitative in nature, is one of the major constraints affecting coconut productivity in Kerala. Adoption of integrated management practices especially effective utilization of inter space in the coconut garden by inclusion of various crops shall constitute an ideal approach to improve the health and productivity of coconut palms. An experiment was undertaken at the Regional Station of Central Plantation Crops Research Institute, Kayamkulam, Kerala from 2004 to 2008 to evaluate the economics of high density multispecies cropping system (HDMSCS) model with different annual and perennial crops in an existing 39 year old West Coconut Tall (Cocos nucifera) garden affected by root (wilt) disease. Various crops such as elephant foot yam, pineapple, banana, black pepper and nutmeg were raised as component crops with coconut in the HDMSCS. The overall coconut yield under the system improved by around 17 % during the fourth year of experiment when compared to the initial yield of 53 nuts/palm due to the management practices including recycling of organic biomass produced through vermicomposting and basin raising and incorporation of green manure crop. In the total cost of cultivation incurred, cost of labour was the highest, ranging from 50 to 75 % during 2007-08 and 2005-06, respectively. The net return varied from Rs.15,064 to Rs.25,687 during 2005-06 and 2006-07, respectively. In the absolute monetary terms, the contribution of inter/mixed crops in the HDMSCS varied from 30 (2005-06) to 51 % (2006-06). Analysis of coconut equivalent yield showed that the overall contribution of inter/mixed crops was about 40 %, indicating the beneficial effects of the cropping system in coconut gardens, especially in areas where root(wilt) disease is a problem causing reduction in farm family income. The economic advantage of HDMSCS over mono cropping was 61 % with a BC ratio of 1.59 indicating that the coconut based high density cropping system is economically viable in root (wilt)disease affected areas provided the disease incidence is well managed by adopting integrated practices and other production and price related risks are at normal level. Analysis of root (wilt) disease incidence from the experimental field indicated significant decrease in the disease incidence due to adoption of HDMDCS in disease affected gardens. | en_US |
