Abstract
The good quality seed act as a catalyst for recognizing the potential of other inputs. The quality seed is the most important input for any crop establishment and contribute a lot for production & productivity. Seed treatment is used to control seed-borne pathogens, insects, pests and inoculants which result in direct seed yield loss through its impact on quality of a seed, germination of seed, and vigor of the crop plants. The availability of viable and vigorous seed at the time of planting is essential to achieve the target of agricultural production. Keeping in view the present study was conducted during 2018-2020 in the laboratories and research farm of the Department of Seed Science and Technology, Chaudhary Charan Singh Haryana Agricultural University, Hisar. To study the Impact of seed treatments and their combinations on seed quality and the association of various seed quality parameters along with field emergence of wheat (Triticum aestivum L.). It was found that seed treated with Azotobacter+Phosphate solubilizing bacteria enhanced the better seed quality in terms of all parameters of fresh and old seed lot of wheat, and Chlorpyrifos showed negative effect on seed quality in various combinations. It is also concluded that enzymatic activities of the catalase, POX, DHA and SOD is enhanced by biofertilizers in wheat seedlings and the performance of old seed lot was low with various seed treatments. So we can say always use fresh seed for sowing purpose to maintain the better plant stand in the field and biofertlizers were seed quality enhancer whereas, insecticides and fungicides retard the seedling growth.
