Tamil Nadu Agricultural University, Coimbatore: The objective is to maximize production of rice-green gram in black clay loam typical Haplustalf at Coimbatore. The treatments consisted of combinations of plant population (5.0×105 and 8.0×105 hills/ha), fertilizer levels (150-50-50, 200-50-67, 250-50-83 kg N-P2O5-K2O/ha) and splits in fertilizer application (3, 4 and 5 splits) to rice. The residual effect of these treatments is being tested on green gram. Another MYR experiment on rice-rice-green manure has been planned at Aliyarnagar involving factors of plant population, fertilizer levels and their splits.
