Not AvailableA field experiment was conducted from 2007-10 at CSWCRTI-RC Sunabeda,Distt. Koraput, Orissa with an objective to access the conservation potential of different Multitier cropping systems and their effect on soil nutrient avialablity. The experiment comprise of treatments such as boundary plantation of forest tree Gliricidia sepium, square plantation of two fruit trees Papaya and Drumstick and four intercrop combinations [Ginger + Pigeonpea (8:2), Runner bean + Pigeonpea (8:2), Ragi + Pigeonpea (6:2) and Ragi broadcasting (as farmers' practice)] on 2 sloping land. Results indicated a significant decrease of 50 (on average basis) both in runoff and soil loss in all the treatments in comparison to control. The comparative study shows Ginger cultivation with Pigeonpea had ameliorative effect to the soil by increase in the pH and available nitrogen of the soil. Among different crop combinations maximum percent increase in nutrients availability was found in Ginger + Pigeonpea (8:2) treatment in all the models to the tune of 12.23 for phosphorus and 17-59 for potassium.Not Availabl
