Two field experiments were conducted in a private farm at Kafr Saad district, Damietta Governorate, Egypt, during 2018/2019 and 2019/2020 seasons to study the effect of three sulfur rates (0, 125 and 250 kg/fed.) and some foliar application treatments (sulfur, selenium, chitosan) in addition tap water as a control and their interaction on broccoli growth, yield and quality. Obtained results revealed that sulfur fertilization at 125 kg/fed. gave the maximum values of No. of leaves, head diameter, total yield and head quality (chlorophyll a+b, vitamin C and total carbohydrates). Foliar application with selenium gave the highest means of No. of leaves, fresh weight of leaves, plant height, leaves area, head diameter, head compactness rate and chlorophyll a+b of head, while foliar application with sulfur gave the maximum values of leaves, head dry matter, total yield and vitamin C content, as well foliar application with chitosan gave the maximum content of total carbohydrates. Thus, it could be recommended that the combined application of 125 kg/fed. of sulfur with the foliar applications with sulfur (4ooo mg/l) or selenium (50 mg/l) or chitosan (3000 mg/l) in broccoli fields can be recommended to enhance productivity of broccoli plants and quality.
Keywords: broccoli, chitosan, selenium and sulfur.
