Effect of integrated phosphorus management on rice yield, grain quality and total uptake of nutrients

摘要

The investigation was carried out to study the effect of Jhabua rock phosphate (JRP) in combination with single super phosphate (SSP), farmyard manure (FYM) and phosphobacteria (PB) on quality parameters and total nutrient Uptake of rice crop (Co 43)in clay loam soil. Combined application of JRP and SSP in 1:1 ratio along with FYM (12.5 t ha~(-1)) and PB significantly increased the grain yield, quality parameter like crude protein content and total uptake of nitrogen, phosphorus and potassium over application of 100 per cent JRP alone but comparable with application of 100 per cent SSP alone.
