    Feasibility of ramie intercropping in coconut
    (2010) Manjunath, B.L.; Ramesh, R.; Korikanthimath, V.S.
    Field experiments were conducted at ICAR Research Complex for Goa for three years during 2005 to 2008 to study the feasibility of growing ramie (Boehmeria nivea (L.) Gaud) as intercrop in coconut. Three treatments that included comparison of sole ramie grown under open conditions, sole coconut and coconut + ramie intercropping system were studied in a Randomized Block Design with six replications. Although sole ramie grown under open conditions recorded significantly higher green (7,843 kg / ha / harvest) and fibre yield (243 kg / ha / harvest) over intercropping with coconut (6,747 kg / ha/ harvest and 210 kg / ha / harvest, respectively), the per unit productivity of green yield was still higher under intercropped situations (0.90 kg / m2/ harvest) over sole cropping (0.78 kg / m2 / harvest) indicating the potential of ramie for intercropping in coconut. An improvement in coconut productivity was observed during the experimental period over the pre-experimental period with an additional 11 nuts / palm / year indicating that the ramie intercropping has a positive influence on coconut yield. It was found that sole cropping of coconut is not much remunerative (Rs.14,830 / ha net returns) while pure cropping of ramie could lead to a net return of Rs. 57,120 / ha / year. However, intercropping of ramie in the interspaces of coconut could fetch a total net return of Rs.81,607 /ha, showing the prospects for intercropping of ramie in coconut in the agro-climatic condition of Goa

    Integrated nutrient management of coconut-based farming system for sustained productivity
    (2004) Singh, S.P.; Manjunath, B.L.; Hameed Khan, H.; Bhanu Shalini
    Among the horticultural crops, coconut stands second in area after cashew in the state of Goa. A field experiment on integrated nutrient management of coconut-based farming system was conducted between 1999-2002 at ICAR Research Complex for Goa in Old Goa. Three manurial treatments viz; T, (100% organics), T, (50% organics+50% inorganics) and T, (100% inorganics were imposed in both coconut and hybrid napier forage grasses NB-21 and PBN-16 intercropped in coconut garden for three year. The results revealed that yield of forage grass NB-21 was same both in treatment T, (127 t/ha) and T, (126.97 t/ha), the difference being non-significant. However, the highest yield of PBN-16 (106 t/ha/year) was recorded in treatment T2 followed by T, (104.9 t/ha/year), the differences being non-significant. Yield of coconut in NB-21 grass plot increased from 42 nutslpalml year (1998-99) to 67 nutslpalmlyear (2001-2002) whereas in PBN-16 grass plot it was from 80 nutslpalmlyear to 78 nutslpalml year for the period although the differences were non-significant. Soil feyility status of plots receiving only organic manures depicted nearly the same pH over three years while plots receiving inorgariic fertilizers showed a lower pH. There was slight increase in the organic carbon content in the manure applied plots especially in coconut basins. Nitrogen content at a depth of 30-60 cm in the coconut basins was found to be high in the plots receiving only inorganic fertilizers. However, the results obtained were non-significant.
