Abstract
The leaf extract of Aonla and Ber showed allelopathc influence over the test crops- Cluster Bean, Moth Bean, Brinjal and Mustard. Cluster Bean and Moth Bean showed significant reduction in germination and seedling growth characters treated with aqueous leaf extract of Karonda. While Brinjal and Mustard recorded a significant increase in these characters following use of leaf extract of Karonda as compared to control. Significant differences in soil nutrient status with respect to N, P, K, Ca, Mg, Mn and Fe content between tree-crop agric system and sole cropping were recorded while non-significant differences were obtained in zinc content among different treatments during initiation and termination of experiment. The nutrient status was recorded to be more in the soils under tree-crop agric system as compared to the soils under sole cropping. A decreasing trend in the nutrient status was observed with increasing depth of soil profile.
