| Abstract | ||
| An experiment was conducted during winter growing season of 2010 /2011 in unheated plastic house conditions belonging to tomato development project in Khor Al-Zubair / Agriculture Directorate of Basrah. The aim was to study the effect of foliar spraying of biostimulators (Terra-sorb and Kelpak ) at different concentrations and the number of times of spraying on some vegetative growth, flowering and yield of eggplant Solanum melongena L. cultivar" Kareem F1". The study included fifteen treatments which were the combinations of five treatments [i.e Terra-sorb 2 and 3 ml/l and Kelpak 3 and 5 ml/l in addition to the control treatment (used water only)] applied with spraying (two, three and four times) at 15-day intervals after month of transplanting . Results showed that spraying with Terra-sorb and Kelpak caused significant increase in all vegetative growth, flowering, Yield and its quality, but reduced in percentage of phenols in comparison with the control treatment. Spraying four times was more effective as compared to two or three times of spraying in most characteristics . The highest early yield and total yield came from foliar spray with 5ml/l Kelpak for four times 1.700, 3.750 kg, respectively . Spraying two times with water only gave the lowest values in early and total yield 0.927,2.100 kg , respectively. | ||
