| Summary: | Water scarcity and global food requirements are two major issues currently that need to be dealt with as soon as possible. Aerobic rice, grown without submergence and requiring occasional irrigation, offers a sustainable solution to water scarcity, contributing to sustainable agriculture. In the present study, nine experimental treatments, consisting of application methods of gel-biofertilizers (seed treatment, soil treatment, and seed + soil treatment) and split application of potassium (at basal, 30DAS, and 50DAS), along with one control, were replicated thrice. Results revealed that application of gel-biofertilizers as seed and soil treatment along with 3 equal splits of potassium recorded significantly higher plant height (97.65 cm), dry weight (27.08 g), panicles/m² (267.20), grain yield (3.35 t/ha), and stover yield (7.47 t/ha). Maximum gross returns (1,80,311.47 INR/ha), net returns (1,10,126.61 INR/ha), and benefit:cost ratio (1.57) were also recorded with the same treatment. Hence it is concluded that application of gel-biofertilizers as seed and soil treatment along with 75% recommended dose of fertilizers with 3 split applications of potassium gives a higher benefit:cost ratio over control (100% RDF).
