Effect of Haulm Cutting, Size of Seed Tubers/Seed Pieces and Intra-Row Spacings on Tuber Yield and Economics of Potato Production

The field experiments were conducted during two consecutive rabi seasons (October – February) 2019–20 and 2020–21 at ICAR-Central Potato Research Institute Regional Station, Gwalior, Madhya Pradesh, India located in west central plains of India. Highest emergence potato plants was recorded with the planting 40 g whole tubers. Growth attributes viz. plant height (58.6 cm) number compound leaves (56.7) highest seed piece/whole tuber.
