(Unpublished).http://krishikosh.egranth.ac.in/handle/1/5810061904Soybean is one of the important oil seed crop and the seeds are stored after harvest till the next sowing or until further use. Therefore the effective seed storage techniques prevent loss during storage and enhance seed quality and seed yield. Keeping in view of these factors, laboratory and field experiment were carried out to study the effect of different seed storage technique on storability and field performance of soybean during 2014-15 and 2015-16 at the laboratory and field of Seed Technology Research Unit, Dr. PDKV, Akola. The result of the experiments is summarized in this chapter. The freshly harvested soybean seeds var. JS-335 was stored in different storage container like polythene bag, cloth bag and airtight container along with silica gel and desiccant beads under ambient condition up to next sowing season.The bimonthly observations on seed quality parameters were recorded in laboratory experiment till the next sowing i.e. up to 8 to 9 months storage. Then the same seed sowed during kharif 2015 to identify the field performance. The observations on the morphological and yield attributing characters were recorded for evaluating the effect of different techniques. The Seed quality parameters differed significantly due to seed storage technique during storage. Significantly maximum seed germination, seedling length, seedling dry weight and vigour index was recorded in seed stored in airtight container by using silica gel. The seed quality of soybean reduces during storage period. Germination percentage was significantly influenced by different seed storage techniques. Germination percentage was found maximum (89.33%) in seed stored in airtight container by using silica gel. The seedling length (28.14cm), seedling dry weight (0.33g), vigour index-I (2513.83) and vigour index-II (29.16) were significantly highest in seed stored in airtight container by using silica gel at the end of 8th month of storage. The effects of seed storage techniques on seed moisture were significant the seed moisture was rapidly decreased in airtight container by using desiccant beads. At the end of 8th months of storages the moisture content ranges from 6.1 to 8.8. Seed infection showed increasing trend with increasing storage period and minimum seed infection (0.67%) was observed in seed stored in airtight container by using silica gel and desiccant beads at the end of 8th month of storage. Maximum seed infection was observed in seed stored in cloth bag (6.41%). Among the all the treatments, maximum initial plant stand (115), plant height (44.87cm)and maximum number of pods per plant (31) .was recorded in the plot in which the seed stored in airtight container by using silica gel. Effect of different seed storage techniques on 100 seed weight (g) was found to be not significant. Significant differences in seed yield were observed due to different seed storage techniques. The maximum seed yield per hector (20.35q) was recorded due to effect of seed stored in airtight container by using silica gel.Soybean is an important crop in India but the lack of availability of quality seed at proper time is one of the important reasons for low productivity in soybean. Seed can store satisfactorily under control condition with low temperature and low moisture .Therefore, rapid loss of seed viability and vigour takes place during storage at ambient temperature. Among the several factors affecting seed storability, seed moisture is also responsible for reduction of germination and vigour. The efforts were made to identify the proper seed storage technique with safe seed storage moisture at Seed Technology Research Unit, Dr.PDKV, Akola (MS).A present study on entitled “Effect of Seed Storage Techniques on Seed Quality and Field Performance of Soybean (Glycine Max (L.) Merrill)”was conducted during 2014-2015 at laboratory and kharif season of 2015-2016 at experimental field. The freshly harvested seed of soybean var. JS-335 were stored in different storage container like polythene bag, cloth bag and airtight container along with silica gel and desiccant beads under ambient condition up to next sowing season. The bimonthly observations were recorded on seed quality parameters in laboratory during storage. The same seed sample was used for sowing in field to assess the field performance. The experimental results exhibited that seed quality parameters differed significantly due to different packing material during storage. Among the treatments the seed stored in airtight container along with silica gel showed significant i.e.heigher seed germination and vigour index during storage. The same treatment performed better in field also significantly maximum plant stand, number pods per plant and height seed yield was recorded in this treatment. However the effect of different storage technique on 100 seed weight was found to be non-significant. Hence the seeds stored in airtight container along with silica gel showed significant result in maintaining seed quality during storage and enhanced the seed yield of soybean.ennullThesis
