Effects of desprouting and sprout length shortening on growth and yield of physiologically old seed tubers of potato variety Kufri Giriraj

Desprouting and sprout length shortening of physiologically old (lanky sprouts) seed tubers followed by immediate and delayed planting in potato variety Kufri Giriraj, revealed that immediate planting after desprouting as well as sprout length shortening was equally effective and better over delayed planting, but was not superior to seed tubers with intact sprouts. Desprouting and sprout shortening upon planting, resulted in delayed emergence but in better plant vigour and more number and yield of total and seed sized tubers than delayed planting of such desprouted/ sprout shortened tubers.
