    Influence of drip irrigation on growth and yield of coconut (Cocos nucifera L.) in laterite soil
    (2007-02) Dhanapal, R.; Ajay Kumar Upadhyay; Subramanian, P.; Sairam, C.V.; Maheswarappa, H.P.
    A field experiment on drip irrigation for West Coast Tall (WCT) coconut was conducted in laterite soil at Central Plantation Crops Research Institute, Kasaragod (Kerala, India) to study the drip irrigation requirement and its influence on growth and yield. The treatments included were three levels of drip irrigation (at 33, 66 and 100% E0 daily), basin irrigation (100% E0) and rainfed control. The experimental results revealed that annual leaf production and leaf nutrient status (N and K) of coconut palm was significantly higher in the irrigated treatments compared to the rainfed control. The female flower production and nut yield with 66 per cent of Eo was on par with 100 per cent of Eo through drip and 100 per cent of Eo through basin irrigation. Drip irrigation equalto66percentof open pan evaporation (Eo) proved to be economically efficient method of irrigation with water saving of 34 .per cent compared to 100 per cent of Eo through basin and drip methods.
