dc.description.abstractThe experiment on drip irrigation was conducted at Agricultural Research Station, Arsikere, Karnataka during 2000-05 in a 25 year-old coconut garden of local cultivar-Tiptur Tall. The quantity of water given through drip system was based on the 10 years average of mean monthly evaporation. Irrigation either through drip or basin system significantly increased the nut yield of coconut over rainfed control. Drip irrigation at 100 per cent Eo recorded significantly higher nut yield compared to drip irrigation @ 33 per cent Eo and 66 per cent Eo and was on par with basin irrigation at IW/CPE equal to 1.0 at 3 cm depth The rainfed control recorded significantly lower nut yield compared to treatments of providing drip or basin irrigation. The increase in nut yield in irrigation treatments over rainfed control was due to more number of functional leaves, production of more number of flowering bunches and female flowers. The leaf nutrient status was also increased with irrigation. The net returns and B : C ratio were highest with drip irrigation at 100 per cent Eo followed by basin irrigation and drip irrigation at 66 per cent Eo. Hence, drip irrigation at 100 per cent Eo is found suitable for coconut in the maidan tract of Karnataka. The water to be applied during summer months (February-May) is 65-75 litres/palm/day while for winter and rainy months (June-January) is 40-50 litres/palm/day.en_US
