Abstract

Two field trials were conducted during two consecutivesummer seasons of 2022and 2023at the Experimental Farm, Faculty of Technology and Development, Zagazig University at Ghazala Region, Sharkia Governorate, Egypt to elucidate the effect of nitrogen fertilizer rates as soil application and foliar spray with seaweed and dry yeast extracts on growth and fruit yield of tomato hybrid (Master R.S.)Treatments included three rates of nitrogen applications (0, 50 and 100 kg/fed) and foliar spray with seaweed extract (2 g/L) and yeast extract (4 g/L).The experiment was laid out in split plot design with three replicates, where the main plot was nitrogen fertilizer rates and the sub- plot was foliar spray with seaweed and dry yeast extracts. The results indicated that nitrogen at the rate of 100 kg/feddan, seaweed extracts (2 g/L) and their interaction effect between them caused an increases in growth characters; plant height, number of leaves, plant dry weight and fruit yield; fruit length, number of fruit/plant, and fruit yield/plant. Consequently: It can be concluded that nitrogen at the rate of 100 kg/feddan and foliar spray with seaweed extracts at 2 g/L and dry yeast extract (4 g/L) increased plant growth characters and fruit yield of tomato cv. hybrid Master R.
