Akshay S Magar, Pragati Misra, Narwade GS, Pradeep Kumar Shukla and PW Ramteke Abstract A pot experiment was conducted during Rabi session to study the effect of different concentration of Vanadium (0, 20, 40, 60, 80, 100 ppm) on morphological and biochemical character of two varieties of sweet corn (Zea mays L.) Madhuri & Phule Madhu. Vanadium was applied at 30 DAS & at flowering time. Results showed that the maximum improvement in morphological and biochemical characters was observed in variety Madhuri at 20 ppm Vanadium as compared to control and the Minimum effect was observed in variety Phule Madhu at 100 ppm. Vanadium applied to plant in low concentration (20 ppm) resulted in improvement of morphological, biochemical character of sweet corn. Keywords: vanadium, sweet corn, growth, biochemical characters Introduction Corn (Zea mays L.) is a versatile crop, also known as queen of cereals. It has found an important place in the human diet, animal feed as well as fodder including industrial raw material like starch and oil. Being C4 plant maize has high yielding potential because this crop has greater ability to convert solar energy into food. Its grain contains about 10 % protein, 4 % oil, 70 % carbohydrate, 2.3 % crude fibre, 10.4 % albuminoids, and 1-4 % ash. It also contains vitamin A, nicotine acid and riboflavin, vitamin E. Maize is important crop in the world grown in more than 150 countries having 600 million ha area with 600 million ton of production. Special corn viz., sweet corn ( Zea mays var. saccarata), popcorn (Zea mays var. everta), baby corn (Zea mays L.), high-oil corn etc. These corns especially sweet corn with their high market value are perfectly suitable to peri-urban agriculture as they promise higher income to maize growers. Sustainability of sweet corn scientific cultivation practices must be ensured to attain the goal of agricultural sustainability. Sweet corn is picked at milk stage and eaten as a vegetable, rather than a grain. Its consumption at immature stage as roasted and boiled ears is a popular practice as the kernels are sweet. Maize is an exhaustive crop and requires high quantities of nitrogen and phosphorus. Low soil fertility is one of the bottlenecks to sustain agricultural production and productivity in India (Khan and Singh. 2017) [6] . Micronutrients play an active role in the plant metabolism process starting from cell wall development to respiration, photosynthesis, chlorophyll formation, enzyme activity nitrogen fixation and reduction (Adhikary et al., 2010) [1] . Vanadium (V) is a transition element widely distributed in nature and biological systems, as well as a part of fossil fuels, and agricultural supplies, such as chemical fertilizers which contain ammonium metavanadate (NH4VO3) (Hector et al., 2017) [3] . V is the 5 th most abundant element among the transitional metals in the earth crust. V is extensively dispersed in the environment by different ways like leaching, combustion, use of fertilizers, and waste material from industries, resultantly, V contaminates the soil, water and atmosphere. The most common form of vanadium is Vanadium pentaoxide (V2O5), followed by ammonium metavanadate (NH4VO3) and sodium orthovanadate (NaH2PO4) (Imtiaz et al., 2014). Vanadium is also essential for several species of fungi and nitrogen-fixing microorganisms but there is little evidence whether it is essential for higher plants (Saco et al., 2013) [12] . Vanadium is a ubiquitous trace metal in the environment, which is an essential trace element for living organisms. With scientific and technological developments, vanadium is clearly poised to become one of the most important elements for the twenty-first century (Teng et al., 2011) [15] . The role of vanadium in plants is very important during proper growth and development of plants on the other hand there are many recent reports,
