“…Pedersen and Lauer (2004) did not verify interaction between sowing date and cultivars for number of pods per area and seeds per pod, as well as in our study. Robinson et al (2009), in a study with sowing dates and cultivars, found important correlation between yield and number of pods according to date of sowing, where late sowing decreased the number of pods for all cultivars, reflecting negatively in seed yield. In the conditions of this study, late sowing did not reduced the number of pods per area.…”

The sowing date is the crop management practice with higher interference on soybean grain yield, although this interference is dependent on the genotype by environment interaction. This study was carried out to evaluate how soybean genotypes behave at different sowing times in a subtropical environment. We evaluated the grain yield, yield components, plant morphology and grain oil and protein content of four soybean cultivars (FPS Urano RR, BMX Apolo RR, BMX Energia RR and BRS 284) at three sowing dates (early, mid, and late sowing in 2010/2011 season) in Mid-South of Parana State, Brazil. Early cultivars at late sowing may have problems with mechanical harvest. The number of pods and grains differed among cultivars, and the cultivar "BRS 284" showed the best results. As an exception, the cultivar "BRS 284" showed yield stability among sowing dates. Higher amount of grain protein content occurs in middle and late sowing dates. The grain yield decreased with delay of sowing due to the reduction of the grains mass and in Southern Brazil is very important to assure high mass of seed to obtain high grain yields.

“…The sowing date is possibly the main and less expensive crop management, which impacts the soybean grain yield (Popp et al, 2002;Robinson et al, 2009). In soybean crop, early sowing can increase grain yield (Wilcox & Frankenberger, 1987) or not change it (Grau et al, 1994).…”

“…Thus, a strategy to boost Japanese soybean yield is needed based on both agronomic practices and genetics. Optimization of sowing dates is the most important and least expensive agronomic practice that affects soybean yield Robinson et al, 2009 . Some researchers have suggested that earlier sowing dates contributed to recent soybean yield gains in the United States.…”

“…Some researchers have suggested that earlier sowing dates contributed to recent soybean yield gains in the United States. For example, sowing soybeans in late April and early May is currently recommended in the Midwestern United States to achieve the maximum seed yield Bastidas et al, 2008;De Bruin and Pedersen, 2008;Robinson et al, 2009 . Sowing before the optimal date is restricted mainly by cool soil temperatures Hu and Wiatrak, 2012 .…”

“…Moreover, the effects of sowing date on soybean yield depend on meteorological conditions and location, especially in terms of the amount and pattern of precipitation Egli and Cornelius, 2009 . Because the beneficial effects of early sowing could be negated under suboptimal soil water conditions Heatherly and Elmore, 1983;Kane et al, 1997;Robinson et al, 2009 , efforts to determine the optimal sowing date should account for regional variations in the amount and pattern of precipitation.…”

Effect of early sowing on growth and yield of determinate and indeterminate soybean (<I>Glycine max</I> (L.) Merr.) cultivars in a cool region of northern Japan

To increase Japanese soybean yield, both practical and genetic improvements are needed. Early sowing improved yields in the United States, where indeterminate cultivars may produce better yields than determinate cultivars, particularly with early sowing. However, the mechanism for the yield response is not fully understood. Furthermore, whether these results are valid for cool regions in northern Japan is unknown. This study tested the effects of early sowing on yield and its attributes in three years using a Japanese determinate cultivar Ryuhou and three indeterminate cultivars Karikei-881 and Karikei-879, recombinant inbred lines from determinate indeterminate crosses; UA4910, a high-yield American cultivar . The effects of early sowing varied among the years. Early sowing significantly increased pod number and seed yield by increasing cumulative intercepted solar radiation thus, growth during early reproductive stages in years with high precipitation during mid-season July and August . High precipitation potentially inhibited canopy development from vegetative to early reproductive stages more strongly in normally sown plants than in early sown plants. In contrast, no significant effect of early sowing was observed in a year with low precipitation during mid-season, when low precipitation during vegetative stage promoted canopy development in both sowing dates. Therefore, early sowing could escape from excess water stress and ameliorate canopy development and thereby seed yield in this region. There was no significant sowing date cultivar interaction for seed yield in any year; thus, the indeterminate cultivars did not benefit more from early sowing in northern Japan. UA4910 had greater seed yield than Ryuhou owing to its longer growth duration and greater aboveground biomass and pod number; Karikei-881, Karikei-879, and Ryuhou showed similar seed yields. Thus, indeterminate cultivars did not necessarily have higher yields in northern Japan. These results suggest that early sowing could be effective for increasing soybean yield in northern Japan.

Soybean [Glycine max (L.) Merr.] yield is a function of many factors including genetic attributes of the cultivar, environmental conditions, and management practices. Temporally variable weather patterns in North America, especially in the northern Great Plains, have resulted in the re‐examination of how spring production practices interact with the environmental conditions to influence yield. This study evaluated the impact of four plantings dates, four seeding rates, and two soybean maturity groups (MGs) using treated and untreated (control) seed on soybean growth, seed yield, and composition. The study was conducted at Volga, SD, in 2014, 2015, and 2016. The planting dates in the study ranged from early May to early July and the four seeding rates were 247,000; 333,500; 420,000; 506,500 seeds ha−1. Stand establishment decreased as seeding rate increased irrespective of planting date. The number of growing degree days (GDDs) to R1 decreased with delayed planting. Delayed planting also decreased the number of GDDs to R8, the length of the reproductive phase (R1−R8), and seed yield. Delayed planting decreased seed yield for both MGs but the rate of decrease was greater for MG 2.4 than MG 1.4. Seed treatment increased seed yield irrespective of planting date. Seed protein was variable among planting dates and between MGs while seed oil decreased with delayed planting. The research documents the impact of delayed planting on soybean yield and quality and highlights the importance of early planting in soybean irrespective of maturity group and growth habit.
