Abstract
The experiment was carried out in one of the plastic houses of the research station belong to the Department of Horticulture and Landscaping/ College of Agriculture/ University of Diyala during the 2014-2015 season to study the effect of adding some of plant preparations containing free amino acids, Humic compounds and micronutrients on growth and yield traits of eggplant var. Sevilla F1" under protected cultivation conditions. The experiment included 7 treatments in addition to the control. A randomized complete block design was used with three replicates, the number of pilot unit were 24 and each one included 10 plants.The results showed that the treatment of adding amino acids + humic compounds + micronutrients was superior in most of vegetative growth such as plant height, leaf area, dry weight of shoot and the relative amount of chlorophyll present in plant leaves (57.52cm, 333cm2 plant-1,108.70 g and 57.33 SPAD unit) respectively, and also superior significantly in giving a highest percentage of N, P, K, Fe and Mn in leaves as reached (3.37%, 0.42%, 3.49%, 223.36 mg kg-1 and 107.52 kg-1) respectively. It was also affected significantly on fruit weight, yield per plant and total yield of plastic house, TSS percentage and content of fruit peel of anthocyanins pigment as recorded (198.60 g, 6.68 kg plant-1, 6.44 t house-1, 6.35% and 784.00 mg 100 g-1) respectively.
