Effect of inorganic fertilizers and biofertilizers on growth, yield and quality of potato

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, to study the response of growth and yield parameters potato processing cultivar Kufri chipsona-1 under different levels of inorganic fertilizers and biofertilizers. The experiment was laid out in Randomized Completely Block Design (RCBD) with three replications. Growth parameters under study were plant height, shoots per plant, leaf area (cm2), diameter of stem (cm), fresh weight of shoots and roots per plant. The findings of present study revealed that due to the effect of inorganic fertilizers good response of growth and yield parameters was observed with the advancement in levels of NPK from 50% upto 100% NPK. Highest marketable yield (19.9 t/ha) and total yield of (21.1 t/ha) was recorded under treatment 100%NPK. Whereas due to the effect of biofertilizer treatments, highest total yield (18.8t/ha), highest starch% (25.1%), dry matter% (23.1%) was obtained with treatment dose (Azotobacter 2.5 kg/ha + PSB 2.5kg/ha).
