Response of Tomato to Zinc and Zinc Solubilizing Microbial Cultures

Tomato (Lycopersicon eculentum L.) belonging to solanaceae family.Its chromosome number is 24. Fertilizer play important role in tomato yield and quality. Macro essential nutrient (N, P,K) and some Micro nutrients such as ( B, Cu, & Zn ) are very important for enzymatic reactions with a plants body such as the making of RNA & DNA, Protein formation , synthesis of cell wall, occurance of flowering and fruit formation, quality of plants. Zinc is an essential Micronutrient required for plants, animals and humans for their normal healthy growth and reproduction. In plants, zinc plays a key role as a structural constituent or regulatory co-factor which contains a wide range of different enzymes and protein in many important biochemical pathways are these are mainely concerned with carbohydrate metabolism, both in photosynthesis and in the conversion of sugars to starch and protein metabolism. Few zinc solubiizing bacterial genera viz. Bacillus spp., Pseudomanas spp., Thiobacillus spp., etc and facultative thermophilic iron oxidizers were reported as zinc solubilizers are used for study to check response.
