Abstract:

The optimum water requirements for trees are important to ideal growth and the manures are important sources of nutrients for sustainable crop production. This experiment was conducted by using irrigation frequency (3, 5, 7, 10 days, irrigation intervals) as main factor and chicken manure rates (0, 0.5, 0.7, 1.0 and 1.2 kg/tree) as minor factor in a split plot experiment based on randomized complete block design with three replications on apple trees of cv. Golden delicious. The results indicated that the frequency of irrigation and chicken manure rates altered vegetative growth characteristics of apple trees significantly. Seven days intervals of irrigation resulted in the best growth characteristics. Application of chicken manure at 0.5 kg /tree can be recommended as a suitable rate.
