RESPONSE OF SORGHUM-WHEAT ROTATION TO DIFFERENT SOURCES OF ZINC IN VERTISOL

Abstract

A field experiment was conducted to study the efficiency of different sources of zinc in sorghum-wheat crop rotation on calcareous vertisol of Parbhani. Zinc application 4kg Zn/ha through zincated superphosphate proved its superiority over other zine sources in producing grain and fodder yield of sorghum. Among the zine snurces, the residual effect of zincated superphosphate was significantly higher in producing grain and straw yield of wheat followed by farm yard manure and zinc sulphate. Zinc application @ 4kg Za/ha through different Zinc sources significantly increased uptake of Zn.N and P by wheat crop. Highest uptake of nutrients was recorded with zincated superphosphate in both the crop.
