Abstract:
Objectives: This investigation was aimed to study the effect of foliar spraying with mono potassium phosphate (MKP) to maximize fruit and oil productivity and quality of Jatropha curcas trees grown under low quality of soil and water (Suez conditions). Methodology: Jatropha curcas trees received three different concentrations (0.5, 1.0 and 1.5%) of MKP at full bloom (once) and after fruit set (twice). Changes in leaf mineral content, flowering, fruit yield and seed oil content and their chemical characteristics of Jatropha curcas trees were determined. Results: The obtained results showed that all mono potassium phosphate spraying induced a remarked promotion in leaf mineral status. Also, enhanced yield and seed physical and chemical characteristics compared with control trees. The best results with regards to foliar application were obtained by spraying MKP at 1% once which superior to increase the number of flowers, fruits per inflorescences, fruit yield per tree and seed weight. A higher proportion of oil and less acidity recorded by mono potassium phosphate at 1.0% spraying once. The lowest peroxide value attained by spraying mono potassium phosphate at 0.5% twice. Conclusion: Foliar spraying of mono potassium phosphate at 1% once gave the best results in increasing the number of flowers, fruits per inflorescences, seed weight and a higher oil content with less acidity.
