Abstract

A pot culture experiment was conducted to study the response of rice to various levels of Zn and Fe with and without FYM in black calcareous soil of Palghar (Thane). Application of Zn at 5 ppm and Fe at 10 ppm with NPK and FYM significantly increased the grain and straw yield of rice over recommended dose of NPK alone. the uptake of N, P and K by grain and straw also increased due to application of Zn at 5 ppm with NPK and FYM and application of Fe at 10 ppm with NPK and FYM as compared to NPK alone." The uptake of Fe significatly increased due to application of Fe with and without FYM as compared to NPK alone. However, Zn application did not show significant effect on Fe uptake. While the uptake of Zn significantly increased due to application of both the levels i.e.. 5 ppm of Zn with NPK and FYM as compared to NPK alone. However. Fe application did not increase the Zn uptake indicating and antagonistic relationship between these two elements.
