Résumé partiel
The present study was carried out duirng 1992 and 1993 seasons at the nursery of Horticultural Research Institute, Giza - Egypt. Uniform and healthy one-year old transplants, of El-Sultani, Gizi and Kadota Fig cultivrs were the plant material of this study, plastic pots of 30 cm. diameter that had been fined with constant weight of nons aline sandy loame soil taken from a depth of 0-30 em, from the surface soil layer of El-Kassasine, Egypt. This area is located about 40 Km. west of Ismailia city. Soil wer chemically and mechanically analyzed before period of equilibration. The pots were filled with about 10 Kg of soil, then the three fig cultivar transplants were planted 111 early February. Irrigation was done at the rate of750 mL/pot at two days intervals till 1st March when the treatments were stared and continued until October in two successive seasons. Thus, we had a three factorial experiments, each one arranged in a complete randomized design to study the following items : 1- The effect of different available soil water levels (100%, 75% ,50% and 250/0)on fig transplants, 2- Effect of some growth retardants (ccc, B9 and PP333 at 250 ppm or 500 ppm) foliar application on fig transplants grown under 25% available soil water at three time i.e., IHMay, 15th June and 1st August.3- Effect of (P, K and Mo) foliar spray on fig transplants grown under 25% available soil water at three time i.e., 1.st May, 15th. June and 1.s1 August.
