Abstract:
A field experiment was conducted at the research field of Odisha University of Agriculture and Technology, Bhubaneswar during rabi, 2021- 22 to study the effect of integrated nutrient management practices on potato (Solanum tuberosum L.) cv Kufri Jyoti. The recommended dose of fertilizer was at 150:80:100 kg N: P₂O₅: K₂O/ha, 25 kg/ha of ZnSO₄ and 15 kg/ha of Borax were applied during the experiment. The maximum growth and yield attributing characters were observed at the application of 125% RDN through chemical fertilizer along with Zn and B which recorded the plant height (52.01 cm), number of shoots per plant (5.27), tuber length (5.71 cm), tuber circumference (14.45 cm), average tuber weight per plant (62.93 g), number of tubers per plant (10.87), harvest index (76.8%) and significantly higher yield (24.73 t/ha). From the perusal of the data with 16 different nutrient management practices, it was found that the application of 125% RDN along with Zinc and Boron significantly recorded the highest net return (Rs. 1,96,200) and B: C ratio of 2.31.
