Effects of location and planting time on physicochemical and nutritional characteristics of soybean seed

Abstract

In the present study, twenty soybean genotypes were grown at two different growing locations <italic>viz.</italic> Ludhiana and Gurdaspur in Punjab, India and planting times <italic>viz.</italic> June and July in the year 2010 with the objective to study the effect of growing environments on physical and biochemical characteristics of soybean genotypes. All the genotypes exhibited higher protein, total sugars and sucrose content while significantly lower mean seed weight, volume, swelling and hydration capacities in July planting than in June planting both at Ludhiana and Gurdaspur. Genotypic (G), Locational (L), Planting time (T), GxL and GxT variations were highly significant for these characteristics. The results reported here show that physical and nutritional characteristics of soybean seeds can be altered by different environmental conditions and this information can be useful to select soybean genotypes for large scale cultivation in Punjab state of northwestern India.

Effect of genotype and contrasting climate conditions on physical and chemical characteristics of soybean (Glycine max L. Merrill)

“…Hydration capacity varied between genotypes from 0.207 to 0.267 g•seed -1 with an average of 0.24 g•seed -1 , while swelling capacity 0.193 to 0.287 ml•seed -1 (Table 2). Our results related to hydration capacity, and swelling capacity are within the range reported by Sridhara et al (1997) and higher than that Goyal et al (2015) as a result of much lower TSW of soybean varieties used in their studies. Accessions with higher seed weight had higher hydration and swelling capacity.…”

“…The relatively high oligosaccharide content of soybeans may play an important role in this effect. Seed yield and seed chemical composition are genetically controlled, however, they are known to be influenced by biotic and abiotic factors, such as fungal and viral infections, insect pests and weeds, maturity, growing season, geographic location, and agronomic practices (Vollmann et al 2000;Medic et al 2014;Bellaloui et al 2015;Goyal et al 2015;Assefa et al 2019;Li et al 2020). The seed chemical composition changes during soybean seed development (Saldivar et al 2011), moreover depends on the seed node position along the main stem of plant (Huber et al 2016).…”

Relationship between seed traits and pasting and cooking behaviour in a pulse germplasm collection

“…In addition, seed traits such as seed weight, hydration capacity and cooking time vary with chickpea genotype (Tripathi et al 2012). However, significant effects of growing environment and storage conditions on physical and biochemical characteristics of grain legumes have also been reported (Sharma et al 2014;Goyal et al 2015).…”
