The Effect of Organic and Inorganic Sulphur Fertilizers on Growth, Pigments and Carbohydrates of Broccoli (Brassica Oleracea L. Varitalica) Plants

The research was undertaken to study the effect of application of different types of organic and inorganic sulfur fertilizers on broccoli. There were three treatments in total consisting of inorganic, organic fertilizers and industrial waste water( WW) .The organic treatment included compost tea( CT) , chicken manure( CKM) and K2SO4 applied with three different concentrations (2.5 , 12 and 50 mg/pot ) as well as blank control. Using different types of soil (100 %clay, 1:2, 1:4 clay : sand and 100 % sand ) .The use of both organic and inorganic fertilizers and irrigation with industrial waste water led to an increase in height, fresh and dry weights and thickness of stem, number of leaves per plant, also have led to an increase in length , fresh and dry weights of the root system compared with untreated samples (control). The use of WW recorded the highest responses than the other treatments with a special regards at 1:4 soil type .The addition of various fertilizers led to a significant increase in photosynthetic pigments compared to untreated samples. The addition of various fertilizers led to significant changes in carbohydrate content in both shoot and root of treated plants. It has been found that these changes depend on the type of fertilizers and the stage of plant growth.
