摘要
Cultivating broccoli in the newly reclaimed soils faces various problems, such as cultivars, fertilization, low amounts of available nutrients. Phosphorus fertilization can influence the curd initiation and development of broccoli. Phosphorus deficiency causes important nutritional problems; therefore, the heavy application of phosphate fertilizers is a routine work necessary to supply the plant with the required amount of phosphorus.A field experiment was conducted in two successive seasons of (2014/2015 and 2015/2016) at Nubaria (Behira Governorate) Egypt, to study the response of vegetative growth, yield and quality of seven broccoli varieties (Centauro, Southern star, Decathlon H, Calabrais, Green sprouting, Condi and BRπ) to three levels of super phosphate fertilizer (15.5% P2O5) (50, 75 and 100 Kg P2O5 /fed). Results indicated that, the highest vegetative growth of broccoli plants was recorded by Calabrais variety which was supplied by 75 Kg P2O5 /fed. Furthermore, the highest total yield and quality of broccoli were recorded by Decathlon H variety supplied by 75 Kg P2O5 /fed in the two seasons.
