Abstract:
A field experiment was conducted during Rabi 2021-22 at Potato and temperate fruit research station Mainpat (C.G.) on Effect of integrated nutrient management on growth, yield and quality of potato (Solanum Tuberosum L.) in northern hill zone of Chhattisgarh. The experiment was laid out in randomized block design (RBD) and replicated thrice, and the potato crop variety Kufri Badshah was sown on 17 November, 2021-22. Where treatments were assigned with seven integrated nutrient management viz, FYM 5 t ha^-1 (T₁), 100% RDF (150:100:100 kg ha^-1 NPK) (T₂), 100% RDF + Azotobactor (T₃), 100% RDF + PSB (T₄), 100% RDF + KSB (T₅), 100% RDF + Azotobactor + PSB (T6), 100% RDF + Azotobactor + PSB + KSB (T₇). Seed rate of 20 q ha^-1 was taken for sowing having a spacing of 60 cm x 20 cm. Result revealed that among all the treatments significantly maximum fresh weight of tuber plant^-1, number of tuber plant^-1, Tuberization efficiency recorded under (T₇) 100% RDF + Azotobactor + PSB + KSB. Application of 100% RDF + Azotobactor + PSB + KSB (T₇) also resulted in to highest total tuber yield t ha^-1. Next superior amongst the all-different nutrient management practices was the application of 100% RDF + Azotobactor + PSB (T₆) caused significantly fresh weight of tuber plant^-1, Number of tuber plant-1 and Tuberization efficiency. Next highest total tuber yield t ha^-1 recorded under the application of 100% RDF + Azotobactor + PSB (T₆).
