Abstract

During the winter (Rabi) season of 2022-2023 and 2023-2024, a field experiment on potatoes was carried out at the vegetable research farm ANDUA&T, Kumarganj, Ayodhya (U.P.), AICRP on potato in Middle Gangetic Plains. Ten treatment combinations with three replications were used in the Randomized Block Design trial. The clay-loam soil used in the experiment had an EC of 0.27 (dS m-1) and a pH of 7.81. According to the soil’s nutrient study, it has available potassium (275.12 kg ha-1), available phosphorus (18.01 kg ha-1) and available nitrogen (175.51 kg ha-1). Maximum plant emergence (96.22 %), number of haulm (7.48 hill-1), plant height at 30 days after planting (DAP) (28.83 cm), 60 DAP (56.20 cm) and harvest stage (60.54 cm), number of leaves per plant at 30 DAP (32.42), 60 DAP (48.72) and harvesting stage (56.25) were noted in T6, while the lowest plant emergence (90.96 %), number of haulm (4.16 hill-1), plant height at 30 DAP (22.04 cm), 60 DAP (45.99 cm), harvesting stage (48.99 cm), number of leaves per plant at 30 DAP (24.18), 60 DAP (40.18) and harvesting stage (45.20) was noted in T10. Compared to the control, the grade-wise tuber was significant in T6.
