    Cash flow analysis of coconut based high density multi-species cropping system – A case study
    (2007-02-08) Sairam, C.V.; Gopalasundaram, P.; Srinivasa Reddy, D.V.; Subramanian, P.; Umamaheswari, L.; Hegde, M.R.
    The cash flow analysis was performed for the coconut based intercropping systems under optimum management conditions for the period 1983-84 to 1996-97, involving banana, clove and pineapple as the inter/mixed crops. The variable capital requirements for adoption of the system ranged between Rs. 8,200/ha during 1984-85 to Rs. 40, 570/ha during 1996-97 for full dose of recommended fertilizers. This was mainly due to the increase in labour cost which alone contributed to 46-72% of the annual maintenance cost. The gross margin realized from the system ranged between Rs. -1,750/ha during 1983-84 to Rs. 92,230/ha during 1996-97. The capital requirement was marginally less when 2/3rd of the recommended fertilizers were applied. The Benefit Cost Ratio of the system was more than three for full as well as two-third level of fertilizers doses.

    Dry-matter production and accumulation in different parts of galangal (Kaempferia galanga) as influenced by agronomic practices when grown as an intercrop in coconut garden
    (2007-02-08) Maheswarappa, H.P.; Nanjappa, H.V.; Hegde, M.R.
    A field experiment was conducted to study the response of galangal (Kaempferia galanga L), grown as intercrop, to agronomic practices in coconut garden during 1995-98. The chlorophyll and carotenoid content did not differ significantly when mother rhizome and finger rhizome used as planting material. Plant population levels of 333,000 and 500,000/ha had the same effect with respect to chlorophyll and carotenoid contents. Organic manures like farmyard manure (FYM), vermicompost (VC) and combination of FYM + NPK and NPK applied alone had significantly higher chlorophyll and carotenoid content. The total dry-matter production increased significantly when mother rhizome, with 333,000/ha population, was used as planting material. Among organic manure treatments, FYM, VC and FYM+NPK significantly contributed to the increase in dry matter compared to composted coir pith (CCP) and NPK treatments. Fresh-rhizome yield was significantly superior with mother rhizome and with 500,000 population level. FYM + NPK combination recorded significantly higher fresh-rhizome yield. The harvest index improved significantly with mother rhizome treatment and at 333,000/ha population. Among organic manures, FYM, VC, FYM+NPK and NPK improved harvest indices compared to CCP and control treatments.

    Effect of long term fertiliser application and cultural practices on soil chemical properties and yield of coconut
    (2007-02-08) Hameed Khan, H.; Gopalasundaram, P.; Mohd. Yusuf; Hegde, M.R.
    Management of coconut groves through cultural practices alone, like cultivation of interspaces twice a year and weed control using herbicides only produced poor yields ranging from 10.7 to 32.3 nuts/palm as compared to fertiliser treatments coupled with cultural practices which produced yields ranging from 83 - 107.9 nuts/palm/year, indicating that cultural practices alone could not sustain higher productivity. However, long term studies have indicated that cultural practices alone are superior to no cultivation and no manuring. For judging the nitrogen status of coconut groves plant analysis may be a reliable index than soil analysis. The plant N levels obtained are much lower even in palms which receive regular fertiliser application on a long term basis indicating that the critical levels established by IRHO may be lowered for Kerala conditions. The palms under cultural treatment have an imbalanced nutrition compared to palms which are regularly fertilized.

    Effect of Sett size, plant population and organic manures on growth components of arrowroot (Maranta arundinacea L.) grown as intercrop in coconut garden
    (1998) Maheswarappa, H.P.; Nanjappa, H.V.; Hegde, M.R.
    Field experiments were conducted during 1995-96 and 1996-97 at CPCRI, Kasaragod to find out the effect of agronomic practices on growth of arrowroot grown as intercrop in coconut garden. Sett sizes (15-20 g and 25-30 g) did not show significant difference with respect to different growth characters, whereas, lower plant population (111 thousand/ha) showed superiority in plant height, number of leaves, leaf area, LAI and LAD over higher density treatment (166 thousand/ha). Among organic manures, Farm Yard Manure, Vermicompost applied alone and FYM + NPK treatments showed significantly superior growth attributes compared to Composted Coir Pith applied alone and NPK alone. Control had significantly lower growth characters.

    Experiences in coconut based farming systems in India
    (2007-02) Gopalasundaram, P.; Thomas Varghese, P.; Hegde, M.R.; Nair, M.G.K.; Das, P.K.
    A sole crop of coconut, at the recommended spacing of 7S x 7S m does not fully utilise the available soil and air space and incident solar radiation. Crops identified as compatible ones with coconut include many tuber crops (cassava, elephant foot yam, yams, colocasia), rhizome-spices (ginger, turmeric), pulses (cowpea), oilseeds (groundnut, soybean), upland rice, fruit crops (banana, pineapple) and vegetables among the annuals and cocoa, black pepper, clove and nutmeg among perennials. Many intensive crop combinations which involve different annuals and perennials over a period of time such as multistoreyed cropping system and high density multispecies crop models have also been developed. Mixed farming systems, which integrate other enterprises like dairying and sericulture provide higher employment generation and enhanced net income. Among the annua! crops, elephant foot yam and ginger are the most profitable. The additional employment generated ranged from 76 to 900 mandays/ha/year in different systems.

    Influence of Agronomic Practices on Growth,Productivity and Quality of Galangal (Kaempferia Galanga L.) Grown as Intercrop in Coconut Garden
    (2007-02) Maheswarappa, H.P.; Nanjappa, H.V.; Hegde, M.R.
    A field experiment was conducted to study the response of agronomic practices on galangal grown as intercrop in coconut garden during 1995 to 1998. Growth, yield characters and yield were superior when mother rhizome was used as planting material, whereas quality characters like oil and oleoresin contents did not differ significantly among mother rhizome and finger rhizome. Per cent reduction in yield under finger rhizome treatment was 2.1 per cent compared to mother rhizome treatment. Plant population level of 500000 per hectare (20 x 10 cm) recorded significantly superior rhizome yield as compared to 333000 population level, whereas quality characters were on par in both the population levels. The per cent reduction in the yield due to lower density population was 6.7 per cent. Growth, yield characters and yield were superior with farm yard manure + NPK combination followed by farm yard manure, vermicompost applied alone. Oil and oleoresin contents were significantly higher with farm yard manure + NPK, farm yard manure and vermicompost applied alone compared to composted coir pith application and control.

    Influence of Organic Manures on Yield of Arrowroot, Soil Physico-Chemical and Biological Properties when Grown as Intercrop in Coconut Garden
    (1999) Maheswarappa, H.P.; Nanjappa, H.V.; Hegde, M.R.
    A field experiment was conducted to study the effect of organic manures on certain physico-chemical and biological properties of soil and crop yield of arrowroot when grown as intercrop in coconut garden. Organic manures like. FYM and vermicompost (VC) application alone and FYM+NPK application decreased the bulk density, improved soil porosity and maximum water holding capacity (MWHC) to a greater extent, whereas composted coir pith (CCP) had its effect on these characters in lesser extent except MWHC. Organic carbon and pH of the soil was increased to a greater extent under FYM and VC treated plots compared to CCP. There was no change in above physico-chemical properties under NPK alone and control treatments. The microbial population and dehydrogenase activity was also higher under FYM and VC treatments compared to CCP treatments, whereas under NPK alone and control there was decrease in the microbial count and their activity. Among organic manures. FYM+NPK combination recorded significantly higher yield componments and fresh rhizome yield (17.1 t/ha) compared to FYM. VC. CCP and NPK applied alone.
