Abstract
ABSTRACT
A field experiment designed in the splitt plot design with three replicates was conducted at a private farm in Abou-Homos distract, El-Behiera Governorate during 2019 and 2020 summer seasons to examined the role of the three soil application with some safety compounds seaweed (2g/l), yeast (2g/l) and garlic extracts (2g/l) as well as the control (zero addition) and the three foliar spraying with some safety compounds Lithovit (2g/l), potassium citrate (2g/l) and mono ammonium phosphate (2g/l) in addition to control (distillated water) on vegetative growth, fruit yield and quality of tomato hybrid ”Soltana”. The results confirmed that Tomato plants that treated with seaweed extract (2g/l) as Soil application had the highest plant height, number of branches and leaves /plant, plant fresh and dry weight, leaves content of total chlorophyll, nitrogen, phosphorus and potassium as well as average fruit weight, fruit yield/plant and fad, fruit length, diameter and firmness in addition to fruit content of TSS, acidity, ascorbic acid, total sugars and total carbohydrates in both growing seasons. Tomato plants that sprayed by mono ammonium phosphate (2g/l) showed the highest plant height, number of branches and leaves /plant, plant fresh and dry weight, leaves content of total chlorophyll, nitrogen and phosphorus in addition to the highest fruit yield /plant and fad in both seasons. Tomato plants that sprayed potassium citrate (2g/l) gave the highest fruit length and diameter as well as TSS, acidity, fruit content of ascorbic acid, total sugars in both seasons. Tomato plants that treated with seaweed extract (2g/l) as soil application and mono ammonium phosphate (2g/l) as foliar spraying had
