Abstract:
Resarch aimed to study the effect of foliar spray with different concentrations of Alar (500, 1000, 1500 ppm) and two planting distances (15 ×15), (30×30) cm and both of them together in vegetative growth and flowering of the plant. The results showed the positive effect of the growth regulator on the development of the vegetative parameter (number of leaves, leaf area, freshweight, dryeeight, percentage of dry matter and the amount of total chlorophyll), as well as the formation and evolution of flowering (early flowering, number of flower stem, total of flowers, number of flower on flower stem and floral diameter) especially when use the medium concentration of growth regulator (1000 ppm) with (30×30) cm planting distances. The results showed the remarkable effect of highest concentration of Alar and highest planting distances on commercial pick flower stem The results also showed the treatment with GA3 concentration of 75 ppm in the indicators of pods production, where the best values and the highest results were recorded in the number of total pods (90.5 pod), fruit weight (11.8 g / pod), production per plant (1067.9 g / plant) and in efficiency. Productivity (60.5%) compared to control plants, which recorded (72.1 pod, 7.1 g/pod, 421.7 g/plant ), respectively. The results also showed the effect of spraying at a concentration of 75 ppm on pods quantity, and recorded (15.60%, 2.63%, 0.9%)on dry matter,protein and ash, respectively, and the lowest in the percentage of fibers with a value (1.12%). .
