Abstract

The vigour and growth of seedlings of CRIC60 cultivar of coconut were studied
in different irrigation treatments during the drought period, in a sandy soil in the dry
zone. Nine irrigation treatments including a control with no watering were tested.
Larger number of casualties were observed in the control while none in the irrigated
plots. The best irrigation treatments in order of response were 40 litres applied twice
a week, two earthenware pots buried on either side of the seedlings and filling them
twice a week (27 litres per week) and 20 litres applied twice a week. However, the
relative efficiency between 40 litres and 20 litres suggest that application of 20 litres
twice a week could be preferred considering the savings on cost and the use of water.
If finances are not limiting burying of two earthenware pots on either side of the plant
and filling twice a week could be preferred.
