| Abstract | ||
| A study was conducted at college of Agriculture University of Baghdad during the growing season of 2000 on Bashecka cultivar to investigate the effect of girdling, urea and potassium spray on fruiting characteristics. Branches have one year old and 2-3 cm diameter were girdled on 1st February – 2000.Three levels of urea (0, 2000, 4000 mg/l) and potassium sulphate (0, 500, 1000 mg/l) were sprayed on 15/2/2000 and 21/2/2000 respectively. A factorial in RCBD design with three replicats for each treatment was used. The results showed that percentage of fruit set significantly increased due to the interaction between girdling and urea and Potassium spray at the highest concentration of either nutrient.Such it is 4.103 % while it was 2.426 % at control . Also showed significant increase in the average fruit weight and the ratio of pulp seed due to the foliar spray of the concentration of urea and potassium.The increase were postively corelated with the concentration of these nutrients.Girdling showed a significant increase in the average of fruit wieght only. Foliar sprays of 4000 mg/L urea and 1000 mg/L potassium or girdling significantly increased fruit dry matter to 24.826 % compard with 22.506 % at control. | ||
