The
higher grain and straw yields were obtained organic manure plus inorganic fertilizers than full dose of
chemical fertilizer and manure. The highest grain (5.93 kg/plot) and straw yields (6.42 kg/plot) were
recorded from I0T5 (Alternate wetting and drying + 50% RDCF plus 4 ton poultry manure/ha) and the
lowest was found in I1T0 (Continuous flooding + control treatment) treatment combination. The
highest concentrations of grain and straw N, P, K, S were recorded in T5 treatment. The levels of
organic matter and nutrient concentration were increased in the post harvest soils due to added manure
plus inorganic fertilizer.
