Abstract
An open field experiment was carried out during the two successive seasons of 2018/2019 and 2019/2020 respectivly, at Badr City, El-Beheira, Egypt to study the effect of saline irrigation water on grwoth, yield and quality of broccoli (Brassica oleraceae L var. Italica) cultivar “Marathon” grown in sand soil. During soil preparation, soil was supplied with 2 ton of gypsum and 7.8 ton of compost/fed., in combination with 2 levels of potassium feldspar (141- 424 kg/fed.), to supplement sand soil with 100 and 130 unites of K2O. Three levels of humic acid (2, 4 and 6 L humic acid/fed.) were foliar sprayed after two weeks post transplanting at 10 days intervals. Plants were arranged in three replicates using randomized complete blocks design. Control was supplied with full NPK mineral fertilizers, as recommended, and irrigated with saline irrigation water. Our results show that saline water decreased growth, yield and quality of control broccoli plants in the two growing seasons. On the other hand, application of humic acid and organic soil amendments enhanced performance of broccoli plants grown under saline water.
