An experiment was conducted at the Experimental Station of the Indian Institute of Horticultural Research Hessaraghatta, Bangalore during the winter season of 1969, to study the suitability and response of four different varieties to foliar nutrition with urea. Four varieties, three indeterminate namely; Pusa Ruby, Sioux and Roi-humbert and one determinate early and dwarf variety viz; CO1 were taken for the present study. It was observed that urea sprays are effective only when they are supplemented with soil application. Urea alone in the form of spray did not give good yield but when it was applied half soil and half as foliar sprays increased yields were obtained. The highest yield of tomatoes was recorded with 50 kg N/ha applied in soil followed by spray with 25 kg/N/ha of urea. Among the four varieties Pusa Ruby gave the best performance followed by Roi-humbert, Sioux and CO1 respectively.
