Abstract

The experiment was conducted at the research station of the College of Agriculture/University of Kufa for the 2022 growing season. The aim of this experiment was to evaluate the eggplant plant response in terms of growth and yield to foliar spray with vermicompost at three concentrations (0. 25 and 50mL L-1) and/or amino acids (Tecamin Max) at three levels (0, 1.5 and 2 mL L-1). The experiment was a factorial, completely randomized block design with three replications. The results showed that the 50 mL L-1 of vermicompost or 2 ml L-1 of amino acids were the best treatments and led to the highest values of plant height (61.00 and 56.44 cm), number of leaves (129.8 and 123.1 leaf plant-1), number of branches (7.33 and 6.89 branch plant-1), fruit length (11.60 and 11.78 cm), fruit weight (228.00 and 238.33 g) and leaf content of carbohydrates (5.93 and 7.10 mg 100 gm-1). Except for plant height, all indicators under study increased significantly in the combination treatments between the two experimental factors compared to the individual treatments and the control treatment.
