Effect of biofertilizer and seaweed extract on growth parameters, fruit quality and yield of strawberry plant

Abstract

This experiment was carried out in the green house of Al-Adawi area of the Damascus Governorate, and in the laboratories of Agriculture, Faculty of Agriculture, Damascus University during the growing season 2020-2021, in order to study the effect of bio fertilizer, Azotobacter Chroococcum (0, 5, 10 ml/l) and seaweed extract, Alga 600 (0, 1, 2 g/l) and their interactions on growth parameters, fruit quality and yield of strawberry plant (cv. Festival). Results observed were that the treatment with biofertilizer (Azotobacter Chroococcum) at a concentration of 10 ml/l supplemented with seaweed extract (Alga 600) at a concentration of 2 g/l were superior to the other treatments and to the control in improving the vegetative growth parameters (24.14 cm, 28.73, 145.81 cm² for plant height, leaf number and leaf area respectively), Fruit quality parameters (3.50 cm, 3.08 cm, 14.96 g, 10.233 %, 59.048 mg/100 g wet weight, 0.953 % for fruit length, fruit diameter, fruit weight, and the content of the fruits of total soluble solids, vitamin C, titrated acidity respectively) and productive parameters (19.80 flowers/plant, 15.87 fruits/plant, 232.36 g/plant for flowers and fruits number/plant and plant

yield respectively).
