Eleven typical pedons representing major landforms in semiarid ecosystems of Jammalamadugu - Proddutur tract of Pennar river basin in YSR Kadapa district viz., summits, backslopes and foot slopes developed from lower Gandikota formation with Quartzite (conglomerate, quartzite and rippled siltstone) and upper Tadipatri formation with purple shale, (siltstone and carbonate complex) under varying land uses were evaluated for actual and potential productivity. The actual productivity of P1 (21.54) and P2 (20.41) situated on summits was average and the potential productivity was good. Similarly, the actual productivity of P3 to P11 located on back slopes and foot slopes was poor and the potential productivity was good. However, actual and potential productivity are increased from summits to foot slopes. The coefficient of improvement ranged from (Ci) from 1.78 (Pedons1 and2) to 4.57 (Pedons 3, 7, 8, 10 and 11). The study revealed that, implementation of judicious soil management practices such as application of green manure/ FYM/crop residues/, contour farming and contour bunding and mixing of soil with tank silt helps not only to achieve sustainable yields but also sustains the soil productivity.
