UTILIZATION OF SOME CHEMICALS FOR STIMULATING WINTER SEASON CROP OF GUAVA.
Selected Guava (Psidium guajava L.) clone of 11 years old, cultivated in clay soil were sprayed with potassium nitrate at 2 & 4 and 6% or ammonium sulphate at 5&10 and 15% at bloom stage. Floral abscission, after two weeks after spraying was enhanced by the two chemical application. Moreover, maximum floral abscission was recorded when trees received to 6% potassium nitrate followed by sprayed with 15% ammonium sulphate. Whereas, the lowest fruit retention of summer crop was caused by 6% potassium nitrate, followed by the ammonium sulphate at 15%, while the control trees recorded the maximum fruit retention. The yield of winter crop was significantly increased by application of potassium nitrate at 6% followed by ammonium sulphate at 5%. Yet, the winter fruits produced from potassium nitrate at 6% or ammonium sulphate at 15% exhibited the highest weight and diameter as well as produced higher T.S.S with low acidity.
