“…The mechanical threshing and processing operations caused significant mechanical damage in both the varieties with significantly higher damage in JS 335 compared to Basara indicating that Basara offered better resistance to mechanical operations than JS 335. These results corroborate to similar results obtained by Delouche [13], Gagare et al [14] and Rodrigo Albaneze et al [15] in soybean.…”

The influence of threshing, cleaning and processing operations on seed quality in two varieties of soybean was studied with an objective to identify the best post-harvest operation to maintain seed viability and vigour. The two varieties viz. Basara and JS 335 were subjected to five different post-harvest operations and two sieve sizes of 3.75 and 4.00 mm. The mechanical damage (%), seed recovery (%), physical purity (%), germination (%), seedling vigour Index II (SVI II), field emergence, electrical conductivity, amino acids and total soluble sugars in seed leachates of processed seed were determined. Among the two varieties Basara recorded lowest mechanical damage and higher germination and field emergence compared to JS 335. The highest seed quality with lowest mechanical damage was reported in seed threshed and cleaned manually. Electrical conductivity showed a non-significant variation in all the treatments while amino acids and total soluble sugars in seed leachates were lowest in Basara. The character association studies revealed a positive association of germination and field emergence and negative association of germination and mechanical damage, amino acids and total soluble sugars in seed leachates.

“…The soybean varieties JS-335, JS-9305 and JS-9560 undergo harvesting and threshing processes employing stick beating, multicrop thresher, and combine harvester. Subsequently, the varieties were subjected to ferric chloride detection and analysis which results indicated that JS-9305 exhibited the lowest mechanical damage (6%) when subjected to stick beating, attributed to its smaller seed size [58].…”

The moisture content during harvesting significantly influences post-harvest losses, encompassing factors that collectively diminish both the quantity and quality of agricultural produce. These factors involve pre-harvest sprouting, mechanical damages and susceptibility to diseases at post-harvest. To mitigate the risks associated with excessive moisture, farmers have to employ proper harvesting techniques such as using a combine harvester. The combine harvester proves invaluable by efficient harvesting, threshing and winnowing various crops like rice, corn, wheat, sunflower and pulses directly in the field. This streamlined process not only saves time and reduces the need for human labour but also lowers overall work costs for farmers. Additionally, the utilization of these machines enhances agricultural productivity, ensuring a more efficient harvesting process and contributing to greater profitability in farming practices. Consequently, effective moisture content management becomes essential for minimizing losses and preserving seed quality. A multipurpose nature of a combine harvester minimizes the need for manual labour in harvesting, leading to a reduction in workforce requirements, time expenditure and effort. Consequently, this enhances overall productivity. The objective of the present review is to describe the effect of moisture content on crop, machine and operational parameters on seed quality of combine harvested crops and discussed the effect of moisture content on mechanical damage of combine harvested seed crop and its germination potential and seedling vigour.

“…Harvesting of soybean between yellow and brown-pod stages followed by drying within pods at low temperatures are optimal conditions for maintaining high seed quality (Ennen, 2011). During mechanical threshing soybean with weak structure is subjected to thrust leading to seed deterioration (Gagare et al, 2014;Kuchlan et al, 2018). High quality soybean seed with minimal damage is obtained at 14.3% moisture content in an axial flow thresher with a feed rate and cylinder speed of 600 to 700 rpm (13.2 to 15.4 m/s) and 720 kg (plant)/h respectively (Vejasit and Salokhe, 2004).…”

Insights into mechanisms of seed longevity in soybean: a review

et al. 2023

Soybean, a crop of international importance, is challenged with the problem of seed longevity mainly due to its genetic composition and associated environmental cues. Soybean’s fragile seed coat coupled with poor DNA integrity, ribosomal dysfunction, lipid peroxidation and poor antioxidant system constitute the rationale for fast deterioration. Variability among the genotypes for sensitivity to field weathering contributed to their differential seed longevity. Proportion and density of seed coat, glassy state of cells, calcium and lignin content, pore number, space between seed coat and cotyledon are some seed related traits that are strongly correlated to longevity. Further, efficient antioxidant system, surplus protective proteins, effective nucleotide and protein repair systems and free radical scavenging mechanisms also contributed to the storage potential of soybean seeds. Identification of molecular markers and QTLs associated with these mechanisms will pave way for enhanced selection efficiency for seed longevity in soybean breeding programs. This review reflects on the morphological, biochemical and molecular bases of seed longevity along with pointers on harvest, processing and storage strategies for extending vigour and viability in soybean.
