Impact of biofertilizers, FYM and inorganic fertilizers on growth yield and quality attributes of potato c.v Kufri Chipsona-1

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 consisting of and three levels of biofertilizers (Azotobacter 5 kg/ha), (PSB 5kg/ha) and (Azotobacter 2.5kg/ha + PSB 2.5kg/ha) and three levels of inorganic fertilizers viz., (100% NPK), (75%NPK) (50% NPK), two levels of farm yard manure (FYM 20 t/ha) and (FYM10 t/ha), applied on potato processing cultivar Kufri Chipsona-1, growth, yield and quality parameters. The experiment was laid out in Randomized Block Design (RBD) with three replications. The tubers were sown in plots of size 3 x 3 m at a spacing of 60 x 20 cm. Observations for yield parameters were processing grade tuber yield (T/ha) 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 total yield (22.6 t/ha). Whereas minimum total yield (15.6 t/ha) was obtained in treatment I1O1B2, during the pooled mean data, of the experiment.
