Fifty genotypes of Soybean, including two checks (JS 20-98 and JS 20-34), were evaluated to assess the effect of various growth parameters on the seed yield of soybean cultivars and to determine their variability in protein and oil content as well as the correlation between both qualitative characters and yield parameters. The study was carried out during the Kharif season of 2019 at Seed Breeding Farm, Department of Plant Breeding and Genetics, College of Agriculture, JNKVV, Jabalpur, (MP). The experiment was laid out in a randomized complete block design (RCBD), having three replications. In the present studies, the data regarding Leaf area index (LAI), leaf area duration (LAD), Chlorophyll content index (CCI), oil, and protein percentage showed that there were significant differences among all varieties. The results from these data were analyzed using PCA and correlation analysis. There was a significantly positive correlation of LAI at 30, 45, and 60 DAS with seed yield. There was a significant positive correlation between LAD-1 (30-45DAS) and LAD-2 (45-60DAS) with seed yield and positive correlation between CCI to seed yield. Significantly negative correlation between oil and protein percent with the seed yield of the plant was observed. It was found that genotype EC 456615 had the highest protein content (41.62%), and genotype EC 389170 had the highest oil content (21.50%) among the studied genotypes.

“…The soybean varieties reached maturity in 85 days in a dry environment while in wet conditions the DM extended to 97 days (Weerasekara et al, 2021). The Leaf area (LA) among the varietal lines of soybean varied between 6.7 ± 0.31 cm2 (NIBGE 41) and 37.2 ± 0.31 cm2 (NIBGE 1).…”

Soybean (Glycine max), an economically significant legume originating from East Asia, serves as a valuable source of protein and oil globally. In Pakistan, soybean is considered a non-conventional oilseed crop, with successful cultivation possible during both the spring and summer seasons. The careful selection of appropriate varieties is a primary concern for soybean growers in the country. Therefore, experiments were conducted utilizing the newly developed varietal line in the agroecological zone of Tandojam to select the most suitable and adaptable varieties. A total of forty-six newly developed varietal lines, which have not yet been released, were evaluated alongside four released varieties (Ajmeri, Faisal, Jack, and Rawal) that are already being cultivated in various regions of the country. The field experiments were carried out at the experimental area of the Nuclear Institute of Agriculture (NIA) in Tando Jam during the spring and summer seasons of 2018. Agronomic traits were recorded for each variety, and weather data were obtained from the Pakistan Meteorological Department. All agricultural practices were followed. The results indicate significant variations among the genotypes for all evaluated characteristics. Based on grain production, NIBGE32 exhibited the highest performance, achieving a notable yield of 22g during the summer season, which was 30% higher than the yield of the top-performing control variety, Faisal. Other newly developed varietal lines, namely NIBGE 18, NIBGE 8, NIBGE 45, and NIBGE 41, also demonstrated promising high-yield potential. These varieties displayed comparatively superior growth and yield outcomes. Germination percentage significantly vary in the spring and summer season (Mann-Whitney U =7925, P<0.01); whereas days to maturity, plant height, leaf area, lowest pod height, 100-grain weight, biological yield, seed weight per plant, were not significantly different in two seasons. This suggests a potential for these varietal lines to be cultivated in both seasons. This research endeavours to offer valuable insights and recommendations to farmers and policymakers, aiming to augment soybean production and advance agricultural sustainability in the region of Sindh.

“…The amount of CAT and POD activities was highest (21.4 mmol/min/mg FW and 83.7 nmol/min/mg FW, respectively) at the time of harvest, which gradually declined with the increase in storage period, amounting to only 6.2 µmol/min/mg FW and 24.6 nmol/min/mg FW, respectively, for CAT and POD activities by the end of the 12 months storage. The weakening of antioxidant defense mechanism resulted in low seed and seedling quality performance [2,39]. Several studies suggested that priming triggers the ROS scavenging process by increasing antioxidant (SOD, CAT, POD and APX) activities and enhanced stress bearing ability of the seedling [11], [38,40].…”

“…De Vitis et al [1] reported that seed deterioration is an inevitable process, even under proper storage conditions. Thus, all seeds undergo deterioration during storage, differing in rate depending on initial seed quality [2] and storage environment [3,4]. In third world countries, tropical in nature, the deterioration is enhanced when seeds are stored under ambient conditions.…”

Soybean seed vigour declines with increase in storage duration, due to ageing, which can be alleviated through seed priming. The objective of this study was to investigate the effects of Humic acid (HA) priming on germination, vigour and seedling performance under laboratory and greenhouse conditions with two soil moisture level [50% and 80% field capacity (FC)]. Seeds stored for 12 months having 60% germination were primed either with 0.2 g/L HA solution or distilled water (hydro-primed) at 25 °C for 1, 3, 5 and 7 h. Non-primed dry seeds were used as control, giving nine treatment combinations. Various germination traits [mean germination time (MGT), final germination percentage (FG%), germination rate index (GRI), seedling emergence percentage (SEP)], mean emergence time (MET), seedling quality traits [seedling vigor index (SVI), shoot length, root length, root volume], antioxidant enzyme activities [catalase (CAT), peroxidase (POD)], lipid peroxidation [malondialdehyde (MDA)] and electrical conductivity (EC) were determined. A germination test in the laboratory was conducted as single factor (nine priming treatments), while the greenhouse experiment was conducted as two factors [2 soil moisture level (50 and 80% FC) and 9 priming treatments]. The results indicated that seeds primed with HA for 5 h was able to reinstate the CAT activities (25%), POD activities (50%) and reduced EC (51%) and MDA content (40%) compared with non-primed seeds, reduced the MET (from 4.3 to 3.5 days), increased FG% (from 62% to 71%), GRI (15.6–21.1) and SEP (from 35% to 54%) and (from 60% to 72%) at 50% FC level and 80% FC level, respectively. A strong negative correlation (r = −0.80 **) was found between MDA content and GRI, while CAT and POD activities had positive correlation with GRI r= 0.67 ** and r = 0.56 **, respectively. Thus, priming with 0.2 g/L HA for 5 h improved the vigour of minimally deteriorated soybean seeds resulting in increased emergence with more uniform field establishment.
