ABSTRACT
Walnut trees infested with plant parasitic nematodes were treated with different organic amendments pigeon manure, horse dung, cow dung, duck manure and castor oil cakes at the rate of 8 Kg/tree and saw dust at the rate of 10kg/tree, respectively. Untreated trees were kept for the comparison. Soil samples and sub samples of both treated and untreated trees after 3, 6 and 12 month from Abbottabad and Mansehra by using Bearmann funnel technique. After Quantitative analysis of both treated and untreated trees, it was observed that treated trees samples showed decline in nematode number as compared to untreated trees. Organic amendments effectively controlled the nematode population. Among all applied organic amendments castor oil cakes and cow dung were found more effective and saw dust was least effective. The studies showed that organic amendments were significantly effective against nematodes.
