Abstract

A field study was conducted during Rabi 2023–24 and 2024–25 at ICAR–CPRI, Regional Station, Gwalior, to assess the postharvest behavior of potato tubers as affected by sowing time, variety and propagation method under ambient conditions. The experiment, laid out in a split-plot design, comprised three sowing times (7th, 17th and 27th November), two varieties (Kufri Kiran and Kufri Sangam) and three propagation methods (apical root cutting, sprout cutting and aeroponics minituber). Early sowing (7th November) recorded the longest dormancy (71.52 days) and delayed rottage (67.89 days), whereas mid-November sowing (17th November) produced the highest sprout number (1.77 tuber⁻¹). Aeroponics minitubers showed the greatest storage resistance (67.26 days to rottage) and sprout cutting enhanced sprouting (2.03 sprouts tuber⁻¹). Varietal differences were negligible. Overall, early to mid-November planting with aeroponic or sprout-cutting propagation improved tuber dormancy, sprouting and storability under ambient storage.
