Abstract

Seedling emergence in different crops was studied in the soil temperature range of 5°C to 45°C. In peas and turnips seedling emergence stopped at a soil temperature of 35°C and in other crops at 45°C. The minimum temperature for seedling emergence was above 10°C in case of cotton, sorghum, rice, maize and musk melon and above 15°C in case of squash, bottle gourd and okra. Winter crops like wheat, gram, peas, and turnips emerged at 5°C but the percent emergence was low. The optimum range for seedling emergence was narrower for vegetable crops as compared with cereals.
