A field trial was taken up during wet season 1989 with different sources of phosphate. viz., superphosphate (SSP), Mussoorie rock phosphate (MRP). partially acidulated rock phosphate (ARP) and Mussoorie rock phosphate with fungi (MRPF). Grain yield of rice was highest with MRPF in conjunction with either green manure or farmyard manure. The fertilizer use efficiency (FUE) was highestfor the combination of MRPF plus green manure.
Super phosphate, Mussoorie rock phosphate, partially acidulated rock phosphate, Mussoorie rock phosphate with fungi, fertilizer use efficiency
