Abstract
The potential of different organic sources like coir dust, coconut sheddings, forest leaves and cattle manure blended with NPK straight fertilisers in establishment and growth of coconut seedlings were assessed at Central Plantation Crops Research Institute, Kasaragod. The data collected for a period of 10 years from 1971 revealed that the addition of blended organic sources, particularly forest leaves and cattle manure markedly enhanced the growth and vigour of coconut palms as compared to palms treated with NPK fertilisers alone (control). The application of these organic sources also efficiently reduced the average mortality of seedlings than those under control treatment. Even the flowering, an index of production, got enhanced in palms treated with blended organic matter. Considerable build up in organic carbon status of coastal sands after 10 years and improvement in related properties like water holding capacity and bulk density were noticed in plots receiving the blended organic treatments. The organic matter blending with NPK significantly increased the available soil N over control after sixth year.
