Nutrient Management

In S.R.I. method, encourage application of organic manures as it enhances the macro and micro nutrients in the soil in an eco-friendly way, helps in optimum utilization of some of the chemical fertilizers and protects the soil from degradation and other hazardous effects. Apply well decomposed farm yard manure or compost @10-12 t/ha before ploughing and incorporate them uniformly. Use different sources of organic manures such as azolla, pre-kharif green manures, crop rotations with legumes and crop residues, etc. rather than single source.

Apply and incorporate 50 per cent recommended fertilizers (NPK) through inorganics depending on soil test values. Though complete organic manuring is recommended for S.R.I., in case of short supply or organic manure this supplementation may adopted for better yield. Apply 50 per cent of the recommended nitrogen and 75 per cent of potassium as basal dose before last puddling and incorporate. Apply second dose (25 %) of nitrogen at the time of second weeding (20 DAT) and final dose of 25 per cent nitrogen and remaining 25 per cent potassium a week before panicle initiation stage.
