Book Description
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.

Book Description
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.

Book Description
Plant breeders continue to make significant advances in developing high yield ing, adaptable, disease-free crops. These advances, however, are not realized until an efficient seed production system is in place that rapidly increases geneti cally superior crops and makes them available to the consumer in large quantities at a reasonable cost. Successful seed production requires seed to be genetically pure, free of admixtures, and able to establish rapidly a uniform stand. Seed production is a complex process. Rigorous production criteria are followed by both seed producer and seed companies to ensure that high-quality seed is produced and marketed. These criteria become even more stringent in hybrid seed production. This volume identifies the factors most critical in a successful seed production operation. The fundamental considerations common to all seed crops are established in Part I, Principles of Seed Production. From this founda tion, the practices of seed production are provided in detail in Part II, Seed Production of Specific Crops.
