Sulfur (S) is an important macronutrient needed for the normal crop performance. As S in an essential constituent of protein, S deficiency results in a limitation in protein synthesis. Sulfur deficiencies are becoming more common because of the cultivation of high yielding crop cultivars, intensive cultivation, application of fertilisers with little S or no S, cleaner atmospheres as well as reduction in retention of crop residues

The aims of the study were to identify the virus belong to Begomovirus genus which infect yellow leaf curl disease on tomato in Lam Dong province.

Phytate, myo-inositol 1,2,3,4,5,6-hexakisphosphate, is the primary source of inositol and the major storage form phosphorus in agricultural feedstuffs, such as cereals, legumes, and oilseeds. Phytase, myo-inositol hexakisphosphate hydrolase (EC 3.1.3.8 for 3-phytase and 3.1.8.26 for 6-phytase), catalyzes the hydrolysis of phytate into myo-inositol and inorganic phosphates
