    Areca based high density multispecies cropping system in coastal Karnataka
    (2007-02-08) Ravi Bhat; Reddy, V.M.; Khader, K.B.A.
    The studies on areca based high density multi species cropping system (HDMSCS) were conducted at Central Plantation Crops Research Institute, Regional Station, Vittal for 10 years from 1983-84 to 1992-93.The results revealed that in a HDMSCS, intercropping did not affect the arecanut yield negatively. Banana is economical in the initial years. Pepper is good inter-crop during the early years and needs replanting after 5 to 6 years in disease prone areas. Cocoa grows well with areca and gives good returns.

    Arecanut (Areca catechu L.) based high density multispecies cropping system in West Bengal
    (2007-02-08) Reddy, V.M.; Baranwal, V.K.; Singh, R.K.
    A study on the high density multispqcies cropping models was taken up in an arecanut garden at Mohitnagar Research Centre during 1983. Nine different crops including annuals, biennials and perennials were tested for their suitability to grow in arecanut gardens, both under irrigated and rainfed conditions. Results of seven years study showed that all the crops can be grown satisfactorily in the interspaces of arecanut. Black pepper was found to be one of the most productive crops, while pineapple and turmeric were least productive. Arecanut, banana, black pepper and cocoa or acid lime can be a most profitable combination for the region. Due to high water table existing in the Research Centre all the crops including arecanut were found to perform well under rainfed condition except shallow rooted crops like betelvine and black pepper.

    Cropping system in arecanut
    (2007-02-08) Reddy, V.M.; Ravi Bhat
    Studies on high density midtbpecies cropping; system in arecanut garden in diflerenX. agro climatic regions of India are remunerative.. While 60 per cent, of the sunlight alone is intercepted by arecamtt palms, by growing intercrops the sunlight utilisation can be increased to about 95 per cent. The interspace of arecanut garden can profitably exploited by raising crops like barurna, lemon, elephant foot yam. cocoa, tapioca, pepper and betcivines

    Effect of weather parameters on arecanut (Areca catechu L.) yield in West Bengal
    (2007-02-08) Reddy, V.M.; Vijayakumar, K.
    The effect of weather parameters oh arecanut yield was studied using correlation analysis. The highly correlated weather parameters werse used in regression analysis to predict arecanut yield. The analysis revealed that 97 percent of yield variation could be explained by minimum temperatures of April, two years earlier, and relative humidity of November and minimum temperatures of December of previous year.

    Photosynthetic and Growth Characteristics of High Yielding Varieties of Arecanut (Areca Catechu L)
    (2007-02) Reddy, V.M.; Ravi Bhat; Balasimha, D.; Khader, K.B.A.
    Photosynthesis, growth and development of three high yielding varieties namely Mangala, Sumangala and Sreemangala were studied during early years of crop growth. Mangala had significantly less set volume and maximum yield compared to all other varieties, without any difference in other growth or photosynthetic characteristics. Mangalas early bearing and high yield seemed to have resulted in less stem volume due to partitioning of more photosynthates to flowering and fruiting during the early years of growth.

    Response of high yielding varieties of arecanut to fertilizer levels in coastal Karnataka
    (1999) Sujatha, S.; Ravi Bhat; Reddy, V.M.; Abdul Haris, A.
    A field study (1985-1997) was conducted at Central Plantation Crops Research Institute, Regional Station, Vittal to determine the nutritional requirement of high yielding varieties of arecanut. Four varieites, viz. Mangala, Sumangala, Sreemangala and South Kanara Local as main plot treatments and five fertilizer levels, viz. 0:0:0; 50:20:70; 100:40:140; 150:60:210 and 200:80:280 g of N:P205:K20 per palm per year, respectively as sub plot treatments were tried in a split-plot design. Both height and girth increments between first and ninth year of experimentation were found non-significant due to fertilizer levels indicating that application of higher dose of fertilizers would have no impact on growth. Yield (dried dehusked nut) varied significantly in different years. Pooled data (1993-97) revealed that both varieties and fertilizer levels significantly influenced the number of nuts and yield. Interaction effect of varieties and fertilizer levels was also found significant. The fertilizer level of 200 g N: 80g P2O5:280 g K20 per palm per year was found to be optimum for Mangala. Application of lOOg N: 40g P205: 140g K20 per palm per year was found to be ideal for Sumangala and Sreemangala. Economic analysis indicated an appreciable increase in net income and benefit-cost ratio with increase in fertilizer dose. Maximum net income (Rs. 2,31,627/ha) and benefit-cost ratio (4.25) were obtained with a fertilizer level of 200g N: 80g P205: 280g K20 per palm per year.
