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.

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.

This book was released on 2018 with total page 46 pages. Available in PDF, EPUB and Kindle. Book excerpt: Soybean seed is one of the most costly inputs for soybean producers. Research was conducted in 2016 and 2017 in Mississippi to evaluate the impact of row spacing, planting date and seeding rate on soybean yield. Additional research was conducted to determine the optimal replant seeding rate, following a sub-optimal stand of soybean, to maximize soybean yield. These data suggest an early planting date, mid-April, at a seeding rate of 296,400 seeds ha−1 , no matter the row spacing, resulted in the greatest soybean yield. No yield differences were observed for a replant seeding rate of 160,500 seeds ha−1 added to a 50% reduced stand when compared to the optimum stand treatment. Soybean yield was greater for the optimum stand treatment when compared to complete removal followed by full replant treatment, or 321,000 seeds ha−1 .

This book was released on 2014 with total page 117 pages. Available in PDF, EPUB and Kindle. Book excerpt: Increased soybean commodity prices and high-yielding cultivars have instigated producers to expand soybean production outside traditional regions. Introduction of soybean to relatively new areas such as the Southern Great Plains, has created the need for management practices unique to the region to exploit full yield potential in these environments. Oklahoma soybean production, for instance, frequently results in low yields due its adverse environmental conditions, along with common late-plantings, as a double crop following wheat harvest. Due to soybean photoperiod sensitivity, delayed planting leads to a shortened vegetative growth period, which potentially reduces seed yield. The influence of management practices, such as seeding rate, row spacing, maturity group selection, starter and foliar fertilization, irrigation, and the use of long juvenile soybean lines, on late-planted soybean yields has not yet been evaluated in the Southern Great Plains. The objectives of this study are to evaluate the effect of these specific management strategies on late-planted soybean yields and their potential adoption in the Southern Great Plains to minimize yield losses in these late production systems. Four different field studies were established on late plantings in Oklahoma as followed by numbers 1, 2, 3, and 4: 1) Four seeding rates ranging from 198,000 to 383,000 seeds ha-1, three row spacings (19, 38, and 76 cm) and two maturity groups (4.8 and 5.6) under rainfed conditions. Seed yield, plant population, canopy cover, and partial economic return were analyzed. Seed yield was not affected by seeding density, but yield results for 38 and 76 cm row spacings showed slight advantage to 19 cm rows. Partial economic return of 38 and 76 cm rows ranged from 13 to 25% greater than 19 cm row spacing, with the greatest returns at the lowest seeding densities. 2) Three soybean lines from maturity group (MG) 6, 7, and 8 carrying the long juvenile trait (LJ) were compared to three high-yielding varieties from MG 3, 4, and 5, in four planting dates from late-May to late-June. Vegetative growth period, canopy cover, seed yield, and seed quality were evaluated. Long juvenile soybean lines had greater growth but similar yields compared to non LJ varieties, due to the extended growth period overlapping early reproductive stages diminishing seed production potential. 3) Fertilization strategies including two starter and four foliar treatments were compared to a control treatment with no fertilizer applied. Starter or foliar treatments resulted in no seed yield differences compared to control treatment. 4) Soybean from MGs 4.8 and 5.6 were sown in 19 and 76 cm row spacings at three seeding rates (247,000, 346,000, and 445,000 seeds ha-1 were tested under irrigated conditions and seed yield evaluated. Seed yield of late-planted soybean under irrigation was affected only by MG. Seeding rate and row spacing had no effect on yield. Average yield of MG 4.8, across row spacings and years was 2620 kg ha−1, which was 25 % greater than MG 5.6 yield (1980 kg ha−1).

This book was released on 2012 with total page 42 pages. Available in PDF, EPUB and Kindle. Book excerpt: Growers can plant soybean [Glycine max(L.) Merr.] with a grain drill or row crop planter, which can affect seed and weed control costs and yield. Farmers planted soybean with a grain drill in 0.19 m rows and a row crop planter in 0.38 and 0.76 m rows at recommended (420,000 seeds ha1) and reduced (321,000 seeds ha-1) seeding rates in two field-scale studies in New York to obtain agronomic information and conduct partial budget analyses to aid growers in future planter purchase decisions. Soybean intercepted more light in 0.19 (65-70%) compared with 0.76 m rows (50-55%) at flowering, despite lower early plant establishment (~70 and ~85%, respectively) at both locations. At the no-till location, soybean in 0.76 m rows compared with narrower rows had greater weed density at full pod stage (19.7 vs. 6.3 and 5.1 plants m-2) and biomass at harvest (13.7 vs. 6.6 and 7.3 g m-2), but similar yield (~3.30 Mg ha-1). At the chisel tillage location, soybean in 0.19 m rows at 420,000 seeds ha-1 yielded more (4.27 Mg ha-1) than other row spacing by seeding rate combinations (4.15 to 4.01 Mg ha-1). Partial budget analyses indicated that soybean in 0.19 m rows at 420,000 seeds ha-1 had ~$30 ha-1 increased profit compared with 0.76 m rows at 321,000 seeds ha-1. Partial budget analyses indicated that for farms without a grain drill the 4% yield advantage offsets costs of purchasing and owning a grain drill and added seed costs at present market and seed price.
