This book was released on 2000 with total page 270 pages. Available in PDF, EPUB and Kindle. Book excerpt: Results from the central location were variable with top yields associated with the intermediate rows in 1998 and the narrow rows in 1999. Plant population also influenced seed yield at each location. The northern location responded with high yields as plant population increased. The central location produced top yields at the medium level plant population. Treatment interactions varied by year and location. Yield components were also measured and analyzed indicating how the different treatment yields were determined. Changes in pod production affected yields the most.

Book excerpt: Plants are important for a permanent ecosystem, because in the ecological pyramid plants support all the other living organisms at the base. Very important organization is thought to be the integral process of resource, transport, partitioning, metabolism, and production, which involves yield, biomass, and productivity in plants. Accordingly, it is important to obtain more information about the knowledge concerning yield, biomass, and productivity in plants. Soybean is one of the main crops largely contributing to our life, which is thought to be connected to our ecosystem through the above-mentioned integral process. This book focuses on the soybean, and reviews and research concerning the yield, biomass, and productivity of soybean are presented herein. This text updates the book published in 2017. Although there are many difficulties, the main aim of this book is to present a basis for the above-mentioned integral processes of resource, transport, partitioning, metabolism, and production, which involves yield, biomass, and productivity in plants (soybean), and to understand what supports this basis and the integral process. It is hoped that this and the preceding book will be essential reads.

Available in PDF, EPUB and Kindle. Book excerpt: Soybean growers in the northern latitudes of the United States plant the crop in a wide range of row spacings although there has been a shift toward wider rows (>50¬†cm) in some Upper Midwest states in the last 5¬†years. The objective of this study was to evaluate the impact of row spacing and seeding rate on the performance of soybean and to determine whether these management practices interact to influence soybean yield. A row spacing study was conducted at Aberdeen and Beresford, South Dakota, USA, in 2014 and 2015. The study had two row spacings (19 and 76¬†cm), four seeding rates (247,000, 333,500, 420,000, and 506,500¬†seeds¬†ha,àí1), and two soybean varieties at each location. Soybean had greater stand establishment in 19¬†cm rows (6,Äì10% higher) compared with 76¬†cm rows. Soybean in 19¬†cm rows yielded 0.8,Äì10% more than in 76¬†cm rows depending on the location or year. Seed yield increased with increasing seeding rate with the highest seeding rate of 506,000¬†seeds¬†ha,àí1 yielding greatest. The increase in seed yield due to the increase in seeding rate ranged from 3 to 7%. At each location, the longer duration soybean variety yielded higher than the shorter duration variety.

This book was released on 2013 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: Abstract: Planting date plays a significant role in determining soybean growth, development and seed yield. The objectives of this experiment were to evaluate the effects of late planting date, management system, and maturity group on the growth, development and seed yield of maturity group VII and VIII soybean under dry land conditions in the Southeastern coastal plain of the United States. Plant growth and development, seed yield, yield components, and seed oil and protein concentrations were evaluated throughout the season. These experiments were conducted in South Carolina at the Edisto Research and Education Center near Blackville and the Pee Dee Research and Education Center near Florence. Soybean was planted at four weekly intervals starting on 15-June in both 2011 and 2012. Pioneer 97M50 (a MG VII determinate variety) and Prichard Roundup Ready (a MG VIII determinate variety) were selected based on their adaptation to the Southeast. The two management systems were: a strip-till (ST) system using a John Deere MaxEmerge Vaccum planter + Unverferth 300 strip till with 96-cm row spacing and a drilled no-till (NT) planting system with 19-cm row spacing. Plant growth was evaluated based on leaf area index (LAI), Normalized Difference Vegetation Index (NDVI), and plant height (HT). Plant development was calculated based on the duration (days) of growth stages. Growth stages were recorded weekly from 10 randomly selected plants in each plot. The beginning of each stage was determined when at least 50% of plants were at that stage. Overall, planting after 22 June appeared to reduce seed yield. The ST system increased the seed yield compared to the drilled NT system. Yields were greater for the MG VIII variety than the MG VII variety. LAI, NDVI, and HT at R2 and R4 were generally reduced with delayed planting dates. Later planting shortened the duration of both vegetative and reproductive growth stages for both MG VII and VIII soybeans. Shortened duration of vegetative growth and seed filling period might have contributed most to the lower yields observed in delayed planting dates. Planting date did not affect either protein or oil concentration. Protein concentration in the seed was found to be significantly higher and oil concentration lower in soybean grown in the ST system than in the drilled NT system. Positive correlations were found between: seed yield and LAI, NDVI, and HT at R2 and R4; seed yield and duration of vegetative and seed filling growth period; and seed yield and dry weight of each plant part (branches, stems, petioles, leaves, and pods).

This book was released on 2022 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: Planting soybean early (late April through early May) is recommended to achieve high grain yields. However, unfavorable conditions can limit farmers’ ability to plant during the recommended period, and thus, an increase in the seeding rate may be necessary. Also, weather conditions can affect seed quality, and choosing an adequate planting date can mitigate the impacts of unfavorable weather on the seed. Thus, the objectives of this study were to (1) measure the effect of planting date and seeding rate on stand loss over the growing season, (2) measure the effect of soybean seeding rate and planting date on grain yield, (3) identify the agronomic optimum soybean seeding rate (AOSR) and the partial economic return for the lowest and highest soybean price, and (4) measure the effect of soybean planting date and seeding rate on harvested seed mass, seed germination, and seedling vigor. For these objectives, a field study was conducted for two growing seasons at two locations in Ohio: Western (WARS) and Northwest (NWARS) Agricultural Research Stations. The experimental design used was a split-plot randomized complete block with four replications. The main plot factor was four planting dates ranging from 25 April through 10 July, and the split-plot factor was five seeding rates ranging from 123,500 to 618,000 seeds ha-1. At WARS-2020, planting soybeans in April through early June had a similar grain yield (5,090-5,285 kg ha-1), while there was a reduction in grain yield when soybean was planted in late June (4,216 kg ha-1). In contrast, in WARS-2021, planting dates did not statically influence grain yield. At NWARS-2020, a small amount of rainfall during the pod-setting growth stages (R3-R4 stages) impacted and reduced the grain yield for soybeans planted in April (3,113 kg ha-1) and May (2,909 kg ha-1) when compared to soybean planted on early-June (3,595 kg ha-1). The AOSR changed among site-years. For soybean grown under normal weather conditions, the AOSR needed to be increased as planting was delayed to achieve the highest grain yield. The planting date factor also impacted soybean seed quality. The germination rate in all site-years was above 94%; however, soybean planted in early June had the lowest seedling vigor results (64 to 81%) compared to other planting dates (80 to 89%) in both locations. These findings can help growers improve grain yield, increase economic return, and produce high-quality seeds.
