Effect of Nutrients and Plant Growth Regulator on Yield and Biochemical Parameter of Tomato (Lycopersicum esculentum L.)

The experiment was carried out during Rabi season 2013-14, Department of Biological Sciences, SHIATS, Allahabad (U.P.) the influence of organic, inorganic nutrients forms and plant growth regulators on various morphological growth, biochemical traits, and yield components in tomato (Lycopersicum esculetium.L.) The experiment was consisting of two organic i.e., FYM and vermicompost at two different concentrations, one P-solubilizer nutrients viz., KNO 3 and FeSO 4 and plant growth regulators viz., salicylic acid and GA 3 with three replications.Significant differences were observed for various morphological, biochemical and yield attributes due to the application of organic, nutrients and plant growth regulators.The plant height increased significantly due to the application of salicylic acid (50 ppm) and P-solubilizer (2.5 kg/ha).The morphological traits viz., number of branches, in leaf increased significantly due to application of organic, nutrients and plant growth regulators.Among various treatments the application of GA 3 (20 ppm), P-solubilizer (2.5 kg/ha) and vermicompost (2 t/ha) were effective in increase plant height, leaves, fruit diameter, & number of fruit.The biochemical parameters tested, like chlorophyll content was significantly higher with GA 3 (20 ppm) followed by vermicompost (2 and 1t/ha).
