Abstract: The present experiment was conducted at the, Department of Horticulture, College of Agriculture, RVSKVV, Gwalior (M.P.) during the Rabi season of two consecutive years 2017-18 and 2018-19. The experiment was comprised of 18 treatment combinations of three levels of inorganic fertilizers viz., (100% NPK), (75%NPK) and (50% NPK), two levels of farm yard manure (FYM 20 t/ha) and (FYM10 t/ha), and three levels of biofertilizers (Azotobacter 5 kg/ha), (PSB 5kg/ha) and (Azotobacter 2.5 kg/ha + PSB 2.5kg/ha) tested on potato processing cultivar Kufri Chipsona-1, for yield and economic parameters. The experiment was laid out in Randomized Completely Block Design (RCBD) with three replications. The tubers of uniform size were sown in plots of size 3 x 3 m at a spacing distance of 60 x 20 cm. Observations for yield parameters were grade wise yield of tubers (kg/plot), processing grade tuber yield (T/ha), marketable tuber yield and total yield (T/ha) of potato tubers. The treatment combination I₃O₂B₃ (100%NPK+FYM 20 t/ha + PSB2.5kg/ha+ Azotobacter 2.5kg/ha) resulted in maximum number of tubers per plant (12.4), maximum ‘A’ grade tubers (8.2 kg/plot), maximum ‘B’ grade tubers (7.5 kg/plot) and maximum average weight of processing (Agrade) tuber per plant (97.0 g) during the pooled mean data, of the experiment.
