摘要

The influence of sowing time and potato propagules on yield and quality of potato was carried out at Agricultural Research Institute, Tarnab, Peshawar during the year 2005-06. Potato tuberlets were developed from Hybrid TPS, OP-TPS and Tissue culture and evaluated against seed tubers for plant growth, yield and tuber quality. The tuberlets from hybrid TPS had significantly higher percent sprouting (92.767%), plant height (65.783 cm), soil cover (91.250 cm2), number of leaves per hill (35.67) and yield (39.126 ton ha-1) with the minimum disease incidence (0.15%), followed by mini-tubers and OP-TPS. The seed tubers had significantly high disease incidence (23.17%) and lower yield (11.414 ton ha-1) but had high tuber quality high TDS (6.242%), dry matter (23.176%) and specific gravity (1.393). Most of the parameters were none significantly affected by sowing on September 15thor September 22ndbut plant height, soil cover, leaves per hill and yield declined with delaying sowing to October 8th.
