A field experiment was conducted for five kharif seasons (2006–2011) in an Alfisol
to study the effect of integrated use of lime, mycorrhiza, and inorganic and organics
on soil fertility, yield, and proximate composition of sweet potato. Application of
graded doses of nitrogen, phosphorus, and potassium (NPK) significantly increased
the mean tuber yield of sweet potato by 44, 106, and 130 percent over control. Green
manuring along with 1/2 NPK showed greater yield response over that of 1/2 NPK. The
greatest mean tuber yield was recorded due to integrated application of lime, farmyard
manure (FYM), NPK, and MgSO4 (13.69 t ha−1) over the other treatments. Inoculation
of mycorrhiza combined with lime, FYM, and NPK showed a significant yield response
of 10 percent over FYM + NPK. Conjunctive use of lime, inorganics, and organics
not only produces sustainable crop yields but also improve soil fertility, nutrient-use
efficiency, and apparent nutrient recovery in comparison to NPK and organic manures.
