| Abstract | ||||
| Two field experiments were carried out at the Experimental Farm of the Faculty of Agriculture, Suez Canal University, Ismailia Governorate during the two successive seasons of 2001/2002 and 2002/2003. The aim of this study was to investigate the influence of seeds inoculation with phosphorein and phophorus fertilization levels (16, 24 and 32 kg P205 /fed) on the vegetative growth parameters, mineral contents, yield of seedless green pods/ plant, total yield of green pods/ fed. number and weight of green seeds/pod and weight of 100 seeds in plants of three cultivars of sugar pea (sugar pearl, snow wind and sugar gem) under sandy soil conditions. Data indicated that all vegetative growth parameters i.e. number of leaves/plant, plant height, shoot fresh and dry weights and leaves area of plants obtained from seeds inoculated with phosphorein were significantly higher than those of un inoculated ones.AII the previous growth parameters increased with increasing the rates of applied phosphorus. Some differences were observed between the three cultivars in this respect. N, P and K were higher in plants treated with phosphorein or with phosphorus than their control and the increments were corresponding with the increase in the rate of applied phosphorus. Best results were obtained from the combination of phosphorein and 32 kg P205/fed. Plants of snow wind cv. had higher N,P ,K than the other two cvs. Yield chracteristics such as number of seedless green pods/plant, pods weight ,length and diameter, yield of pods/ plant and total yield/ fed. significantly increased with phosphorein and with increasing the rate of applied phosphorus as well as with combination of phosphorein and the highest rate of P. Number and weight of seeds/pod and weight of 100 green seeds followed a similar trend and the snow wind cv. gave the best recoroed parameters. The obtained results revealed that under sandy soil conditions, the snow wind cv treated with phosphorein before sowing and fertilized with 32 kg P20sl fed is the recommended cv for producing the highest yield with good quality. | ||||
