Comparative study of organic, inorganic and biofertilizers on growth performance and yield of potato (Solanum tuberosum L.)

A field experiment was carried out at the Vegetable Research Farm, ANDUA&T, Kumarganj, Ayodhya (U.P.), under the AICRP on Potato during the Rabi seasons of 2023-24. The study was conducted using a Randomized Block Design (RBD) comprising 7 treatment combinations, each replicated three times. The results indicated the highest Plant emergence % at 30 DAP (97.74%), Plant height (22.42 cm at 30 DAP and 52.10 cm at 60 DAP), Number of leaves plant^-1 (17.25 at 30 DAP and 54.21 at 60 DAP), tuber yield (25.07 t ha^-1), haulm yield (12.52 t ha^-1), were observed in treatment T₂. In contrast, the lowest plant emergence % at 30 DAP (93.06%), plant height (13.05 cm at 30 DAP and 30.54 cm at 60 DAP), number of leaves plant^-1 (13.68 at 30 DAP and 42.24 at 60 DAP), tuber yield (17.39 t ha^-1), haulm yield (9.80 t ha^-1), was recorded in treatment T₁ (Control). An organic and inorganic source of nutrient management helps assess soil nutrient status, improve soil health and nutrient availability.
