Field experiment was conducted to study the suitability of targeted yield equations evolved for MTU-1010 to other similar rice cultivars during kharif season, 2019 at the research farm of Inidira Gandhi Krishi Vishwavidyalaya, Raipur, C.G. Experiment was laid out in strip plot design having five treatments in each strip replicated thrice. The treatments consisted of eight rice varieties as strip and five treatments T1- Fertilizer application for Yield Target (YT) of 60 t/ha; T2- YT 50 t/ha; T3 – Control (No NPK application), T4- FYM (5 t/ha) and T5-GRD (120:60:40 kg ha-1 NPK). The results revealed that IGKV-R2, Karma Masuri, Mahamaya and IR-64 varieties have successfully achieved the yield targets from the fertilizer prescription equation evolved for MTU-1010. The efficiencies of fertilizer N, P and K were higher with targeted yield-based treatments followed by GRD and FYM application. However, higher benefit cost ratio (BCR) was observed in GRD (120:60:40 kg of fertilizer N P K kg/ha) due to application of inorganic fertilizer N, P and K without FYM as compared to STCR yield target of 60 and 50 q/ha which received fertilizer application with 5 t/ha FYM and high cost of FYM applied was also included with cost of inorganic fertilizers contributed higher BCR. It can be concluded from the study that the STCR based fertilizer prescription evolved for MTU 1010 variety of rice can be used for four varieties of rice under study i.e. IGKV-R2, Karma Masuri, Mahamaya and IR-64.
