A long-term rice-wheat experiment was conducted at Parwanipur, Nepal, to study the effects of organic and mineral sources of nutrients on yield and nutrient status of the soil. Twelve treatments comprising different combinations of inorganic N, P, and K; farmyard manure (FYM); and wheat chopped straw (WCS) were included. On average during a 20-year period, the control plot with an indigenous nutrient supply supported 2.06 Mg rice ha–1 and 0.69 Mg wheat ha–1. The application of 100 kg N ha–1… CONTINUE READING
