After harvesting, soybean seed must be thermally treated because of the increased moisture content. The most common thermal treatment of soybean is roasting, with three indicators that are critical for the process itself: seed moisture content, roasting period and process temperature. Following the above-mentioned, the aim of this paper was to determine nutritional and energy changes in three soybean varieties (‘Gordana’, ‘Sivka’ and ‘Slavonka’). After collecting the samples, the nutrient structure of the core and energy components of seed hull for each variety were determined before and after the heat treatment by roasting. The roasted soybean seeds of the specified varieties were dried by exposure to temperatures of 125°C and 135°C in the duration of 10, 20 and 30 minutes. The results show that significant changes occurred in nutritional properties of soybean seed core in relation to temperature and time of roasting, as well as to assortment. There are also significant differences in elements, which affects the energy properties of soy seed hulls depending on temperature and duration of the procedure.

Seed treatment (ST) is an important practice for soybean crop. This research had the objective to evaluate the influence of seed moisture content in the response to different spray volumes (SV) used for seed treatment in soybean, considering effects on seed physiological quality. Three seed lots with distinct moistures were used: 7.2%, 10.1% and 13.0%. Untreated seeds (control) and three SV were tested: 8, 13 and 18 mL kg-1. All lots received the same treatment combination, containing insecticide, fungicide, fertilizer and biostimulant. This combination represented 8 mL kg-1 of SV; the doses of 13 and 18 mL kg-1 were obtained by adding 5 and 10 mL kg-1 of water, respectively. Evaluations of seed physiological quality consisted of electrical conductivity, seed respiration, germination and vigor tests. Results of all tests demonstrates that low-moisture soybean seeds (7.2%) are negatively affected by seed treatment within an SV range of 8 to 18 mL kg-1, while untreated seeds with equal moisture are not affected. Oppositely, high-moisture seeds (13.0%) are not affected by the SV tested, while intermediate-moisture seeds (10.1%) are affected by the higher SV. This result highlights seed moisture as a key parameter to be managed before soybean ST, aiming to maintain a high physiological quality.

Soybean (Glycine max) seed loses its viability in the storage which causes shortage in supply of quality seed and consequently hinders the expansion of soybean cultivation in Bangladesh.Losses of seed viability of soybean (Glycine max) in traditional storage is very common in the tropical environment. An experiment was conducted at the Seed Laboratory, Regional Agricultural Research Station, Bangladesh Agricultural Research Institute (BARI), Jamalpur in 2011 and 2012 to find out the effect of seed moisture content and types of storage container on soybean seed germination and seedling vigour. In 2011, soybean seed having 94% initial germination was stored at 8, 10 and 12% moisture levels but in 2012 seeds having 96% initial germination was stored at 6, 8, 10 and 12% initial moisture levels in four different types of storage containers viz., polythene bag, plastic pot, tin can and glass jar. weredays after storage ().The experiment was arranged in a factorial completely randomized design with three replications. In 2011, high germination of soybean seed (77-85%) was retained at 200 DAS for those stored at 8% initial seed moisture content (SMC) in any of the containers. Germination index and seedling dry matter decreased with increased initial seed moisture content irrespective of storage containers used. Tin preserved higher seed moisture contents of 9.93, 11.71 and 14.15% for seed stored at 8%, 10% and 12% initial seed moisture content, respectively. In 2012, 80-94% seed germination was retained at 200 DAS for those stored at 6% initial SMC in any of the containers. The germination declined to a range between 75.0 and 91.3% within 200 DAS at 8% initial SMC while those stored at 12% SMC showed rapid germination loss and the value showed down to between 9.3 and 22.0%. Vigour index and seedling dry matter decreased with increased initial seed moisture content irrespective of storage containers used. Tin also Seeds stored in tin container showed the higher final seed moisture contents irrespective of initial seed moisture content. Bangladesh Agron. J. 2018, 21(1): 131-141

One of the obstacles in providing high quality soybean (Glycine max) seed is the infection of seed-borne fungal pathogens. Micro wave treatment is one of the alternative methods to control the seed-borne pathogens effectively but it needs to be further developed. This research consisted of two stages. The first stage was aimed to determine the best soybean seed moisture content in maintaining seed physiological quality after exposing to micro wave. The second stage was aimed to determine the most effective duration of micro wave exposure to reduce the rate of infection of seed-borne fungal pathogens using the best moisture content resulted from the first stage. The experiment  on seed moisture indicated that 9.20% was the best seed moisture content in maintaining the physiological quality when the seed was exposed to micro wave.  Furthermore, micro wave exposure of 60 seconds was able to control Aspergillus flavus, while the exposure of  80 seconds was able to control Fusarium sp., Curvularia sp., and A. niger.

<p>Soybean seed viability declines during seed storage. Soybean seed deteriorates rapidly, affected by its high protein content and often high humidity in the tropical environment. This research was aimed to develop dynamic model of soybean seed viability in an open storage. The study was conducted in three stages, namely: 1) desk study, 2) seed storage experiment, 3) development of seed storage model, simulation and verification of the model. The second stage of the experiment consisted of soybean seed storing and germination testing using completely randomized design. Treatments were three initial moisture content (7-8%, 9-10% and 11-12%) and four varieties of soybean (Anjasmoro, Wilis, Detam-1 and Detam-2). The results showed that the seed behaviour during storage period were affected by initial seed moisture content, initial viability, varieties and environmental condition. Therefore, seed moisture content, initial viability and varieties may be used as input model. Moisture content, integreting seed respiration, electric conductivity and seed storability vigor (VDSDB) were as model output. Simulation of Seed Storability Vigor Prediction Model with Model Construction Layer-Stella (MCLS) using relative humidity (RH), temperature, seed permeability, initial moisture content and initial viability as input model could logically predict the seed moisture content and seed storability vigor (VDSDB).</p>

Deterioration of seeds during storage may reduce the supply of high-quality seeds which become the limiting ‎factor of soybean production in tropical countries. Controlled Deterioration Test (CDT) is one of the ‎fastest vigor testing methods. The objective of this study was to achieve the suitable moisture content and ‎duration of CDT treatment in soybean seed, then establish a model that associated with the seed vigor in ‎the field after a certain time of storage. Split-plot with 2 factors, namely seed varieties and the combination of ‎moisture content and heat exposure duration were used to determine the influence of CDT treatment. ‎Another split-plot for 2 factors, namely storage period and seed varieties were used to determine the effect ‎of shelf life. Viability parameters were observed by germination strength (GS) and seedling vigor index (VI), ‎using a rolled paper towel method. The results showed that there was an interaction between soybean seed ‎varieties and the combination of seed moisture content treatment with duration of CDT exposure. Sindoro ‎and Tanggamus varieties had higher viability and storability than other varieties. Combinations of 28% seed ‎moisture content for 24 hours CDT duration were sensitive enough to evaluate the physiological potential of ‎soybean seeds, providing information that was closely related to seed germination after stored for 1 month. ‎

It is common to see in any soybean plant that seeds reach maturity at different times. Thus the objective of the present study was to determine the magnitude of the seed moisture range at different stages of maturation in a soybean plant. The field study was conducted in a tropical region in the state of Mato Grosso - Brazil, established with foundation seeds of the MTBR-45 cultivar, and at flowering, 100 plants were marked at the same maturity stage. Harvesting began when seeds still were at high moisture content (MC). At each of eight harvesting times, during 16 days, all pods from two plants were harvested and the seeds from each pod were hand threshed individually and determined the moisture content . The results revealed that there is a great distribution of seed MC in a soybean plant, where at physiological maturity, the magnitude can reach more than 30 percentage points. Also, even with an average MC below 12%, there were more than 20 % of the seeds with MC above 13% and some seeds at this point had been waiting to be harvested for more than a week. The following conclusions and/or recommendations can be taken: 1- The great seed MC range in a soybean seed lot harvested at field maturity leads to the presence of seeds susceptible to mechanical damage and with MC unsafe for adequate storage; 2 - It is recommended that harvesting be accomplished when the seeds are in the 15-18% MC range, in order to minimize field deterioration and the percentage of seeds with high MC; 3- Drying is recommended, even when soybean seeds are in their average MC safe for storage.

An experiment was conducted at the Seed Laboratory of Regional Agricultural Research Station (RARS), Jamalpur during the period from May to November 2010 to study the effect of thickness of polythene bags on quality of soybean seed during storage. Seven levels of thickness of polythene bags viz. i) 0.02mm, ii) 0.03mm, iii) 0.04mm, iv) 0.05mm, v) 0.06mm, vi) 0.07mm and vii) 0.08mm were include as treatment in the trial. Seed moisture content, germination percentage, vigor and seedling dry matter weight were taken during May to November 2010 at two month intervals. Results showed that during the storage period the lowest seed moisture content and highest germination percentage, vigor index, seedling dry matter weight and field emergence were found for seed stored in 0.08mm thickness polythene bags. The germination of seed at two months after storage ranged between 76% to 95.3% and that was between 0% and 90.7% after six months of storage under ambient room condition. Soybean seed could be stored safely at ambient condition with more than 80% germination for six months by keeping them in polythene bags having thickness between 0.03mm to 0.08mm with 8% seed moisture content.

To find out the effect of storage relative humidity, seed moisture content and type of storage container on soybean seed quality, an experiment was conducted at the Seed Laboratory, Department of Agronomy, Bangladesh Agricultural University Mymensingh in 2008 and 2009. In 2008, soybean seed has 96% initial germination and in 2009 seed having 98% initial germination was stored at 8% and 12% initial moisture levels in two types of storage containers viz., cloth bag and polythene bag (0.06mm thickness). The final seed moisture content, germination percentage, germination index, and seedling dry matter of the seed under different treatments were measured at 60,120, and 180 days after storage (DAS). The experiment was arranged in a completely randomized design with three replications. In 2008, highest germination percentage (89.33%) of soybean seed was retained at 180 days after storage (DAS) for those stored at 8% initial seed moisture content (SMC) in polythene bag at 50% relative humidity. Germination index and seedling dry matter decreased with increased initial seed moisture content irrespective of storage containers used. In 2009, highest germination percentage (92.67%) of soybean seed was retained at 180 DAS for those stored in polythene bag at 8% initial SMC at 50% of the relative humidity. Those stored in cloth bag at 12% SMC showed rapid germination loss and the value went down to 0.00 in both the years. Vigour index and seedling dry matter decreased with increased initial seed moisture content irrespective of storage containers used. DOI: http://dx.doi.org/10.3329/bjar.v39i3.21989 Bangladesh J.
