Vegetable crops comprise a major part in Indian agriculture in terms of providing food and nutritional security. Recommended per day consumption of vegetables is 300 g. In recent past, Indian agriculture has witnessed a tremendous progress in vegetable production, due to the advent of high yielding varieties and new technologies. Vegetables are important sources of vitamins, minerals and other nutrients of medicinal and therapeutic value. Due to the percent of low germination rate and seedling emergence yield of the crops decreasing day by day. Poor seed germinations and inappropriate crop stand are the main constraints in the production of vegetable crops. Farmers are not having sufficient resources for seedbed preparation for sowing and they are at more risk as compared to progressive farmers. On the other hand good establishment increases competitiveness against weeds, increases tolerance to drought period, increase yield and avoids the time consuming need for re-sowing that is costly too. Seed priming increase the percent of germination and reduce the time of seedling emergence side by side improve the crop stand. A method to improve the rate and uniformity of germination is the priming or physiological advancement of the seed lot. Seed priming is the method of improve germinations and uniform emergence of seedlings in field conditions. Although it will improve the vigour and crop establishment and finally enhance the yield. It is a very low cost hydration technique in which seeds are treated with various chemicals or sometimes with normal water also. After treating the seeds are re-dried and show in the field. Seed priming is generally adopted for better crop stand, germination and yield of various vegetable crops.
