This study was conducted during the kharif, 2020 at ICAR-Perunthalaivar Kamaraj Krishi Vigyan Kendra, Puducherry, India aimed to examine the effect of fortified in situ rice residue compost, zinc nano fertilizer on the growth and yield of rice under rice cultivation methods. The experiment was conducted in a split plot design; 3mainplots (TPR, DSR and AR) and eight subplots (fortified manures and nano zinc particles) with three replications. The results revealed that the TPRsignificantly improved tillers, LAI, productive tillers, panicle weight, grain and straw yield, zinc content and uptake and it was statistically on par with DSRand superior over AR. Nutrient management, fortified manure + ZnO NPs (SP+FS) significantly registered higher growth and yield attributes, Zn content and uptake of rice over to ZnO seed priming alone, ZnSO4 and control. The PGPM, humic acid and seaweed extract fortified organic manures either FYM or rice residue compost, nano zinc as seed priming and foliar spray under TPR or DSR have the potential to maximize rice production without foregoing soil sustainability
