Determination of
Optimal Doses of Fertilizer and Farm Yard Manure for Coconut Production A trial
of NPK fertilizers and farmyard manure was conducted for two years to find out
their effect on the production of nut. Determination of economical dose of
fertilizer and farmyard manure on the yield of coconut was initiated in July
2001 and is still in process. The first year results revealed that the highest
yield (507 nuts) was obtained with 700 urea: 270 DAP 1600 MOP g/plant while in
second year the maximum yield of 658 nuts was obtained under same treatment.

Evaluation of Various
Procedures for Protection of Coconut Plants from Insects and Rodents
Studies
on the evaluation of various procedures for the control of foliar pests
indicated that the injection of systemic insecticides on trunk of palm and
drenching the crown were the most effective techniques for pest control.
Preliminary observation on the control of the Red Weevil indicated that
drenching the affected crown of palms with diluted systemic insecticides
(monocrotophos and methamidophos) could kill the larvae inside the trunk. The
Red Weevil activity was mostly noticed during August and September 2003. Rodent
population and their control measures were studied in the coconut. The rodent
activity and damage was noticed during April and November 2003. The rat species
Rattus rattus 81 was found causing damage to coconut. The damage by rats in
coconut was 12.5%. To control the rats acute rodenticide (zinc phosphide),
chronic (brodifacoum) and rat band of iron galvanized sheet on trunk were used.
Results showed that brodifacoum baits was the most effective and it showed 94%
reduction in rodent activity, while zinc phosphide baits and rat band of iron
galvanized sheets were less effective and showed 84% and 65% reduction in
rodent activity, respectively.
Effect of Different
Irrigation Intervals on Physical Quality and Yield of Custard Apple
The
results revealed that there was significant correlation between yield and
irrigation frequency. The conclusion could be drawn on the basis that
irrigation at six days interval produced highest number of fruits of greater
weight (215g each) and size (22.60cm). It was followed by 8 days interval in
irrigation and 9 days interval, respectively.
