Soybean genotypes grown in sub-tropical climate may exhibit lodging. The plant lodging is influenced by soil type and fertility level, sowing date, latitude and altitude of the location, plant population and conditions of crop development. Plant regulators and herbicides are able to avoid or reduce plant lodging. This study aimed to verify the effects of the growth regulators TIBA and daminozide on vegetative growth and yield of soybean cultivar CD 214 RR. The experiment was carried out at a field in randomized block design with four replications in a factorial scheme. The A factor was represented by the combination of regulators TIBA and daminozide and its concentrations, and the Factor B was seven times of evaluation of injury and plant height or eight times of evaluation of lodging. In the range of doses used, the application of daminozide resulted in greater injury to soybean plants than TIBA. The smaller plant height was achieved by the application of 6 g ha-1 of TIBA and 1200 g ha-¹ of daminozide. Treatments with daminozide (100 g ha-¹) and TIBA (10 g ha-1) stood out due to the reduced lodging of soybean plants. Grain weight increased linearly when the levels of TIBA increased. There was a negative correlation between lodging and grain yield and a positive correlation between plant height and lodging. There was also a negative correlation between injury caused by the application of plant regulators and lodging.

The aim of this investigation was to estimate the effects of different amounts of nitrogen on the grain yield and nutritive value in two soybean genotypes (Laura and Lana). Studied varieties belong to different maturity groups (Laura is in the group I, while Lana is in the group II) and they both have reduced content of Kunitz trypsin inhibitor (KTI). Four treatments of fertilization were tested: 0 kg N ha-1, 30 kg N ha-1, 60 kg N ha-1 and 90 kg N ha-1. Field trials were carried out in dry land farming, at location Putinci, during the years 2008 and 2009. In both research years, variety Lana had higher grain yield and oil content then variety Laura. Method of nitrogen fertilization has been proved as an effective tool for increasing of grain yield and protein content in both varieties. The results of the study showed that application of 90 kg N ha-1 increased the grain yield and protein content of soybean more than application of other treatments (0, 30 and 60 kg N ha- 1). All nitrogen fertilization levels decreased the oil content.

Lower sunlight caused by overcast skies from June to July in Southern China is one of the main environmental stresses that frequently occur and affect the post-silking growth and grain development of spring maize. In this study, a field trial involving four maize hybrids as materials was conducted to investigate the effects of post-silking shading stress (30% and 50% light deprivation) on leaf nitrogen metabolism and biomass accumulation during maize growing seasons in 2016 and 2017. Results indicated that 30% and 50% shading stress caused the grain yield to decrease by 47.3% and 69.6%, respectively. Plant post-silking biomass accumulation was decreased by shading, whereas the translocation from pre-silking assimilates in the vegetative organs was increased by shading. This change was sharply observed when the plants were deprived of more sunlight intensity. The leaf relative chlorophyll (soil and plant analyzer development (SPAD) value) and soluble protein contents were considerably decreased by shading under 50% light deprivation condition. The activities of nitrate reductase, glutamine synthetase and glutamate synthase that are involved in nitrogen metabolism were downregulated by shading stresses. In conclusion, nitrogen metabolism was disturbed by shading, which induced the decrease in post-silking dry matter accumulation, ultimately resulting in grain yield loss.

The Relationship

The yield and protein performance in a soybean genotype result from its interaction with the prevailing environmental conditions. This makes selecting the best genotypes under varied target production environments more complex. This study’s objectives were to determine protein content and protein stability of 30 elite soybean genotypes in major soybean-growing areas of Uganda, assess the yield performance and stability in soybeans and determine the relationship between the protein content and grain yield in soybeans. The genotypes were planted in a randomized complete block design of three replications for six seasons across eight locations in Uganda. Genotype and genotype-by-environment (GGE) biplot analyses classified the test locations into three mega-environments for soybean protein and grain yields. Genotype NII X GC 20.3 had the highest mean protein content of 43.0%, and BSPS 48A-9-2 and BSPS 48A-28 were superior for the mean grain yield (1207 kg ha−1). Bulindi was the most discriminating and representative test environment for soybean yield. A weak and negative correlation (r = −0.1**, d.f. = 29) was detected between the protein content (%) and yield (kg ha−1). The highest-yielding genotypes BSPS 48A-9-2, BSPS 48A-31, and Nam II × GC 44.2 are recommended for further evaluation under farmers’ production conditions for selection and release as new soybean varieties in Uganda.

Glycine Max L

<p>Soybean (Glycine max L. Merril) has been cultivated in regions of lowland soils in crop rotation with irrigated rice in order to reduce the infestation of red rice and due to the attractive soybean value in the world market. Soybean cultivation under this condition is subject to possible soil flooding, requiring recommendations of genotypes adapted to this environment. The aim of this study was to evaluate the grain yield of soybean genotypes grown in floodplain environment at three different sowing times. Cultivars used were A 6411 RG, A 7321 RG, BMX Apolo RR, BMX Ativa RR, BMX Energia RR, BMX Potência RR, BMX Turbo RR, IGRA RA 518 RR, IGRA RA 626 RR, IGRA RA 628 RR, NA 5909 RG , NS 6262 RR, NS 7100 RR, RA 728 RR and VMax RR; sown in October, November and December. The experimental design was 15 (cultivars) x 3 (times) factorial with 4 replicates. Significant differences were observed for sowing times and cultivars, as well as for the interaction between the two factors. Cultivars sown in November and December provided higher yields than those sown in October. BMX Turbo RR cultivar showed higher consistency for soybean yield in lowland, considering the sowing times evaluated. For early sowing (October and November), A 6411 RG cultivar presented higher grain yield compared to the other cultivars.</p>

Location Interaction

In the present study, performance of five promising soybean genotypes over 4 locations during kharif 2013, 2014 and 2015 were investigated using GGE biplot analysis. Location attributed the highest proportion of the variation for all the traits except 100 seed weight ranging from 26.97-86.81% whereas, genotype contributed only 3.01-60.51% and genotype x location interaction contributed 6.01-31.42% of total variation. For 100 seed weight genotype has contributed major proportion of variation (66.26%) than location (31.08%) and genotype x location interaction (2.65%). Superior genotypes for key traits viz., grain yield (VLS 86) and 100 seed weight (Himso 1685) were effectively identified using GGE biplot graphical approach. It may be stated from present study that, VLS 86 was the closest to ideal genotype with stability for high grain yield as well as earliness. ‘Which-won-where’ study partitioned the testing locations into two mega-environments: first with three locations with VLS 86 as the winning genotype; second mega environment encompassed only one location with Himso 1685 as the winning genotype. Existence mega environments was found correlated with the rainfall pattern and clearly suggested that different entries need to be selected and deployed for realising maximum grain yield in hill zone.
