Abstract

Glyphosate (0.694 kg ha -1 ) was given as a single pre-harvest foliar spray at 50, 55, 60, 65, 70, 75 or 80 days after planting (DAP) and its effect on sprout growth was studied in two potato cultivars differing in dormancy duration. Glyphosate treatment was effective in suppressing sprout growth during storage at 18°C and the reduction in sprout length varied from 49 to 83% in Kufri Bahar (short dormancy) and 40 to 58% in Kufri Jyoti (medium dormancy). Glyphosate application generally did not affect tuber yield but increased the incidence of tuber cracking in Kufri Jyoti from 15% (control) to 20-39%. Single treatment of glyphosate at 60 DAP was most effective and double treatment did not enhance the sprout inhibiting effect of glyphosate. get maximum sprout suppression with no adverse effect on yield.
