Boron is an essential nutrient element for growth of all higher plants nitrogen-fixing cyanobacteria. Its deficiency and toxicity can lead many anatomical, physiological and biochemical changes. Present study was conducted to evaluate the effect of boron on seed germination and plant growth of brinjal (Solanum melongena L.). Brinjal (egg plant) is an important vegetable crop of Gujarat. The soil of Gujarat is drought prone, so boron availability might get affected by soil moisture. So it is important to check the effect of nutrient applied by foliar application, which can lead a way for improve plant quality.

Most of the biochemical and metabolic activities have been studied in land plants and also work has been done in the case of aquatic plants especially submerged hydrophytes, hence it was considered as interest to study Hydrilla with the objectives such as physico- chemical parameters of water, growth pattern and biochemical changes of Hydrilla plant and Correlation between physico-chemical parameters of water and biological parameter of Hydrilla

Hamisar is central to the social and cultural consciousness of Bhuj city. This heritage lakes speaks of the suffering of the drought years, and the joy of the good years.Lake studies are conducted to meet specific purposes like Protection of present water quality, Water Quality Impacts associated with Eutrophication and Restoration of former water quality.After complete investigation the result of physical and chemical parameters were compared with WHO (1971) and BIS (1991) standard. After comparing the 98 result it was found that many number of parameters were above desirable limit, which indicate that water of Hamisar lake show some level of pollution
