    Consumptive use and irrigation requirement of arecanut palm (Areca catechu)
    (2007-02-08) Mahesha, A.; Abdul Khader, K.B.; Ranganna, G.
    The water requirements of arecanut palm {Areca catechu L.) in the coastal tracts of Karnataka were estimated based on the evaporative demand of the crop. The crop-water demand was evaluated by using the crop-coefficient and the potential evapo-transpiration values. The potential evapo- transpiration values for the region were computed by modified Penman method using a computer programme on monthly and weekly basis for 1971-85. The depth and quantity of water, the frequency of irrigation and the total number of irrigations required varied from month to month. The requirement of water was more during March-May in arecanut than during other months.

    Influence of Weather on Arecanut And Cocoa Yield
    (2007-02) Vijayakumar, B.G.; Veerappa Devaru, G.; Balasimha, D.; Abdul Khader, K.B.; Ranganna, G.
    Regression analysis of weather variables suggested that yield was influenced by relative humidity, pan evaporation and rainfall in arecanut while temperature influenced cocoa yields. In case of arecanut the regression equation explains eighty four per cent of variations in yield. The equation is not a good fit in case of cocoa for predicting yield.
