Effect of sources and levels of phosphorus and FYM on yield attributes, yield and nutrient uptake of maize (Zea mays L.).

摘要

The effects of phosphorus source (single super phosphate (SSP)), Udaipur rock phosphate (URP), SSP + URP and URP phosphate solubilizing bacteria (PSB) and rates (40, 60 and 80 kg/ha), as well as farmyard manure (FYM; 0 and 10 t/ha) on the yield and nutrient uptake of maize plants were determined in a field experiment conducted in Rajasthan, India during the rainy seasons of 2001-02. The number of cobs per plant, number of grains per cob, 100-grain weight, grain and seed yield, and N and P uptake increased with increasing rates of P and FYM. Among the P sources used, SSP gave the highest values of the parameters measured..
