Horticulture Research and Extension Station, Arsikere

Genesis of the station

            The Horticulture Research and Extension Station, Arsikere was established in the year 1958 by the Department of Agriculture as Regional Coconut Research Station. Later, it was handed over to the Department of Horticulture in 1963. During 1965, research station was handed over to the University of Agricultural Sciences, Bangalore and renamed as Agriculture Research Station. In 2009, research station was transferred to University of Horticultural Sciences, Bagalkot and renamed as Horticulture Research and Extension Station.

·         Planting of seed nuts: Planting of seed nuts in horizontal position at 30 cm apart is ideal to get good stand of robust seedling compared to vertical planting.

 

·         Planting of coconut seedlings: Planting of coconut seedlings at 60 cm deep in 90 cm pits is ideal for good growth of plants.

 

·         Spacing for coconut: Planting of tall coconut at 9 m x 9 m spacing is ideal for better growth and yield.

 

·         Use of coir pith compost as source of nitrogen to coconut: Raw coir pith can be made into compost of good manurial value by using ligno-cellulolytic fungi, Pleurotus sajorcaju and used as a source of nutrients to coconut. The composted coir pith (CCP) can be applied to coconut palm to supplement 50-100% of the recommended dose of N (25-50 kg CCP).

 

·         Drip irrigation requirement of coconutDrip irrigation at 100% Eo is ideal for coconut in maidan tract of Karnataka as it produces higher nut and copra yield and results in higher WUE, net returns and B:C ratio compared to basin irrigation. The water to be applied during summer months (February-May) is 65-75 litres per palm per day while for winter and rainy months (June-January) is 40-50 litres/palm/day.

 

 

·         Fertigation requirement of coconut: Fertigation of 75% RDF is recommended for coconut. Application of 75% of recommended NPK through drip irrigation produced nut and copra yield on par with the application of 100% of recommended NPK and also with the soil application of 100% of recommended NPK indicating the possibility of saving 25% of recommended NPK through fertigation.

·        Fertilizer recommendation for hybrid coconut: A fertilizer level of 1000:250:1000 g N, P2O5, K2O per palm per year is optimum for hybrid coconut (COD x WCT) in the maidan tract of Karnataka as it produces higher nut and copra yield and results in higher net returns and B:C ratio.

 

·         Suitable intercrops in coconut: Intercropping of banana, drumstick, french bean-ladies finger and red gram with adult coconut palms is productive and remunerative. The crops are to be selected depending on the availability of irrigation water. When there is a good source of irrigation water, high water requirement crop like banana or medium water requirement crops like drumstick, french bean and ladies finger can be grown. Under limited source of irrigation water, red gram can be grown as a rain fed crop with need based protective irrigation.

·         Suitable medicinal and aromatic crops for coconut gardens: Lemon grass (Cymbopogon flexuosus), garden rue (Ruta graveolens), tulsi (Ocimum sanctum), Kalmegh (Andrographis paniculata), arrow root (Maranta arundinaceae) and makoi (Solanum nigrum) are the promising medicinal and aromatic plants for intercropping in coconut gardens of maidan tract of Karnataka.

  • Coconut based cropping system: The coconut based cropping system of coconut + cocoa + lime + drumstick under integrated nutrient management developed at Arsikere Centre of AICRP on Palms showed higher productivity and income than monocrop of coconut. The net returns were higher under fully organic nutrient management (Rs. 294810/ha) followed by 50% of recommended NPK + organic recycling with vermicompost + vermiwash application + biofertilizer application and in situ green manuring (Rs. 284410/ha) and 75% of recommended NPK + organic recycling with vermicompost (Rs. 274590/ha).

 

  • Flower crops as intercrops with coconut: Growing of flower crops as intercrop in coconut is remunerative than monocrop of coconut. The cropping system of Coconut + Chrysanthemum recorded significantly higher net income (Rs. 256400//ha) followed by Coconut + Crossandra (Rs. 163300/ha), Coconut + Jasmine (149000), Coconut + China aster (Rs. 144350/ha) and Coconut + Marigold (Rs. 104150/ha). The monocrop of coconut recorded significantly lowest net income of Rs. 53400 per ha.

 

·         Management of basal stem rot disease of coconut: The combined application of Hexaconazole (1%-100 ml) root feeding at quarterly interval along with soil application of neem cake @ 5 kg/palm/year + Trichoderma viride @ 50g/palm/half year is effective in the management of basal stem rot disease of coconut.
