Item Influence of Long Term Cultural Operations on Physical and Water Retention Characters of a Red Sandy Loam Soil(1986-06) Joshi, O.P.; Varghese, P.T.; Nelliat, E.V.; Hameed Khan, H.The effects of long term manurial-cum-cultural practices, imposed since 1919 and modified in 1972, on physical and water retention properties of a red sandy loam soil planted to coconut, were studied. The treatments like forking basins after inorganic fertilization, no tillage and no manuring, and tillage with organic and inorganic fertilization, showed an improvement in water holding capacity, bulk density, estimated porosity and available water capacity over the treatment of tillage alone when tested for their cumulation effect during 1982. More or less a similar trend was observed for water retained at various tensions. However, the treatments like forking basins after inorganic fertilization, no tillage and no manuring and tillage with organic and inorganic fertilization had an edge over other treatments. The data revealed that minimum disturbance of soil by way of forking after inorganic fertilization helped in maintaining better physical environment in basins of coconut palms over other treatments.Item Recent Advances in the Management of Coconut-Based Ecosystems in India(1980) Nair, P.K.R.; Varghese, P.T.Coconut palm (Cocos nucifera L.), cultivated in about 1.1 million hectares, mainly in the southern parts of the west coast of India, is the mainstay of the economy of Kerala State and forms the-major visible component of the ecosystem of the area. Traditionally, it is cultivated in small homestead gardens of areas less than 1 ha. and scientific innovations have made little impact on its management by the small farmer. Experimental results have shown that cultivation operations for weed control and proper management of inputs such as nutrients and water can increase the yields of palms substantially. A major scientific initiative in recent years, aimed at increasing the productivity of the coconut areas, is the intensification of land use through combination of compatible crops (and sometimes animals) under or between the palms. Considerable progress has been achieved in identifying the crops that grow well with coconuts and perfecting the agrotechniques of such combination cultures, and the farmers are taking up the practice in a big way. Ecological implications of these new initiatives in the management of the coconut-based ecosystem are examined.Item Recent Advances in the Management of Coconut-Based Ecosystems in India(1980) Nair, P.K.R.; Varghese, P.T.Coconut palm (Cocos nucifera L.), cultivated in about 1.1 million hectares, mainly in the southern parts of the west coast of India, is the mainstay of the economy of Kerala State and forms the major visible component of the ecosystem of the area.
