Abstract

The study titled “Influence of NPK on Growth, Yield and Nutrient Content in Potato (Solanum tuberosum L.)” was conducted during the Rabi season of 2021-2022 at the Research cum Demonstrational Farm, College of Agriculture, Indira Gandhi Krishi Vishwavidyalaya, Raipur (C.G.). The experiment followed a Randomized Block Design with three replications. It consists of twelve nutrient (NPK) treatments included absolute control viz., (T0) 0:0:0 NPK kg/ha, (T1)-0:80:150 NPK kg/ha, (T2) 120:80:150 NPK kg/ha, (T3) 180:80:150 NPK kg/ha, (T4) 240:80:150 NPK kg/ha, (T5)-300:80:15 NPK kg/ha, (T6)-240:0:150 NPK kg/ha, (T7)-240:40:150 NPK kg/ha, (T8) 240:120:150 NPK kg/ha, (T9) 240:80:0 NPK kg/ha, (T10) 240:80:50 NPK kg/ ha, (T11) 240:80:100 NPK kg/ha and (T12) 150:100:100 NPK kg/ha. The growth, yield and Nutrient content attributes of Potato including the, number of leaves per plant(449), number of compound leaves per plant (79.3), total weight of tuber (11.94 kg/plot), total tuber yield (35.80 kg/plot), fresh haulm weight (336.33g), Dry haulm weight (39.00g), nitrogen content (2.96%), phosphorus content(0.227%) and potassium content (0.573%) was recorded highest in T5; 300:80:150 NPK kg/ha which, was statistically at par with T8;240:120:150 NPK kg/ha but unmarketable yield (kg/plot) was found highest in T12; 150:100:100 kg/ha (4.90 kg) which was noted statistically at par with T2; 120:80:150 NPK kg/ha (4.67 kg).
