Abstract

This study was conducted during the two consecutive summer seasons of 2020 and 2021 at the farm of the Faculty Agriculture, Al-Azhar University, Assiut, Egypt to study the effect of some treatments on Thuraya and Princes tomato hybrids. These treatments are garlic at rates 5,10 ml/L and licorice extracts at rates 5,10 ml/L , as well as the concentrations of boron at 2,4 ml/L and calcium 4,8 ml/L beside the control (non-coefficient). All applications were added four times starting after 45 days transplanting at 10 days intervals. Measurements of plant height, number of leaves, number of branches, total chlorophyll content, total soluble solid, average fruit weight per plant, total yield of crop expressed in tons\fed were recorded in this investigation. The data was statistically analysed, and the result shows that there was a significant differentiation in the characteristics between the hybrids, as well as a significant difference between treatments and interaction between them in both seasons. The best treatments used were garlic extract concentration 5 cm per litre, and the average increase in the total yield was estimated at 24.4% compared to control.
