Item Coconut(Naya Udyog, Kolkata., 2006-01) Rajagopal, V.; Parthasarathy, V.A.; Naresh Kumar, S.; Reddy, D.V.S.; Rohini IyerItem Effect of fertilizer application through micro-irrigation technique on nutrient availability and coconut productivity(2012-12) Subramanian, P.; Dhanapal, R.; Mathew, A.C.; Palaniswami, C.; Upadhyaya, A.K.; Naresh Kumar, S.; Reddy, D.V.S.An investigation was conducted to study the response of drip fertigation in West Coast Tall variety of coconut for growth, nutrition, physiological parameters and yield at Central Plantation Crops Research Institute, Kasaragod during 1996-2008. The application of fertilizers either through drip fertigation or soil application resulted in significantly higher trunk height and girth at base than control (no fertilizer). However, no significant difference was observed among different dose of fertigation and soil application treatments. The number of leaves on the crown was significantly higher(32.6) under 75 per cent of NPK through drip fertigation which was on par with 50 per cent and 100 per cent NPK through drip fertigation and 100 per cent NPK through soil application and significantly differed from 25 per cent NPK through drip fertigation and control. Fertigation to coconut resulted in a marked increase in available nitrogen, phosphorus and potassium status in soil. Different levels of fertigation did influence significantly physiological parameters like net photosynthesis (PN), transpiration (E) and stomatal conductance (gs). The treatment, 100 per cent NPK applied through fertigation resulted significantly higher PN, E and gs and which was on par with 50 per cent and 75 per cent through drip fertigation and significantly differed from 100 per cent NPK though soil application and control. Among the fertigation levels, coconut yield was significantly higher in 100 per cent NPK fertigation (131nuts/palm/year) which was on par with 75 and 50 per cent NPK applied through drip irrigation and significantly differed from 100 per cent NPK through soil application, 25 per cent NPK through fertigation and control. The study indicated that adoption of fertigation increases the productivity with 50 per cent saving of chemical fertilizers which ensure the higher efficiency of nutrients in crop production.Item Foliar traits of jasmine plants intercropped in coconut(2007) Arunachalam, V.; Reddy, D.V.S.Shade is one of the important limiting factors in intercropped agro-ecosystems. Objective of this work is to analyze the role of eight foliar traits of juvenile plants of five different species of Jasminum grown under coconut shade. The results reveal the shade tolerant J. pubescence to produce more number of nodes and longer shoots in all the three seasons studied. J. grandiflorum produced longer leaves and internodal distance than other species tested. Winter season shoots were longer with more number of nodes and longer internodal distances than rainy season. Results are discussed in relation to the adaptive behavior of plants to shade.Item Homestead farms in Northern Kerala - Their basic characteristics and socio-economic status(Indian Society for Plantation Crops, 2007-08) Krishnakumar, V.; Reddy, D.V.S.A study on the crop diversity, farming practices followed, availability of credit and marketing facilities, constraints faced and economics of cultivation in homestead farms was undertaken in 815 homestead farms of four northern districts of Kerala (Kasaragod, Kannur, Kozhikkode and Malappuram) during August-October, 2002, using an interview schedule and Participatory Rural Appraisal techniques. The results indicated that the size of homestead fanns ranged from 0.04 ha to 2.40 ha with an average of 0.54 ha and coconut based cropping system was the most predominant system followed by majority of farmers (98.0 per cent). In general, only a small percentage of farmers (6.5) were found to adopt various package of practices for crop production. Family labour alone was used in 56.0 per cent of the homestead farms, whereas in around 17.0 per cent of farms, only hired labour was used to carry out some kind of cultural operation. The sale of farm commodities was mostly through middlemen (68.4 per cent) thus making the marketing system most unprofitable. As the size of homestead farms increases, there is an increase in the investment made and the profit obtained on account of cultivation of more inter crops and inclusion of other enterprises. The net profit of small and medium sized homestead farms (< 0.5 ha and 0.51 to 1.0 ha) ranged fmm Rs. 4,815 to Rs. 8,050 and from Rs. 8,650 to Rs. 11,500 in the case of Malappuram and Kozhikkode dishicts, respectively. The trend in the case of large homestead farms p1.0 ha) was different, wherein the net profit ranged from Rs. 14,650 in b u rdi strict to Rs. 18,975 in Malappuram district. High cost of cultivation, low availability of labour, lack of credit facility and availability of technical information, non-availabilityof inputs in time as well as storage and marketing facilities for commodities, non-availability of quality planting materials etc are the major constraints experienced by the fanners for successful maintenance of homestead farms.Item Production of polybag seedlings in coconut(2006) Krishnakumar, V.K.; Reddy, D.V.S.Item Restructuring of homestead farms for sustainable income and employment opportunities(2007) Krishnakumar, V.; Reddy, D.V.S.; Thamban, C.; Sairam, C.V.Item Restructuring of homestead farms for sustainable income and employment opportunities(2008-09) Krishnakumar, V.; Reddy, D.V.S.; Thamban, C.; Sairam, C.V.
