Abstract


To assess the effect of amendments and Zn individually and in combinations" on the availability and uptake of N and P.in alkali soil, a pot study was conducted with rice as test crop. Gypsum at 50 per cent requirement in combination with prossmud (12.5 t/ha) or deincha (25 t/ha) resulted in higher available N. Addition of FYM (25 t/ha). registered the highest available P. Zinc application had the favourable influence ovar." available N, while the availability of P was in the revers? trend. Amendments and Zo significently influenced the content and uptake of N in the grain, while the effect was) not significant in straw. Zinc addition had an antogonistic effect on the content of Pin grain and straw.
