This book was released on 2006 with total page 218 pages. Available in PDF, EPUB and Kindle. Book excerpt: The study investigates interaction effects between water availability and planting density on the grain yield of soya beans (soy beans) for the purpose of refining the existing planting density recommendations for local use. The experiments show that the increase in grain yield obtained by raising planting density was due to an increase in the number of pods per unit area and the number of seeds per unit area. The interaction effect between soil water availability and planting density is also highly significant.

This book was released on 2017 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: Soybean (Glycine max L. Merr.) planting date and plant density are agronomic decisions made simultaneously at the beginning of the growing season that can be used to maximize yield and economic return. Research on these basic soybean agronomic decisions must be conducted to support the expansion of soybean production in northern growing regions of the Northern Great Plains (NGP). The objectives of this study were to evaluate the effects of planting dates based on soil temperature on soybean emergence, maturity, and yield for short and long season varieties in Manitoba, and to determine optimum soybean plant density for early to very late planting dates in northern growing regions of the NGP. In the first experiment, calendar date had a greater influence than soil temperature at planting on soybean yield. Soybean yield declined with later planting rather than increasing soil temperature at planting. The earliest planting dates resulted in the greatest soybean yields. In the second experiment, soybean yield-density relationships were responsive to planting date. Yield-density relationships formed early/mid (May 4 to 26) and late/very late (June 2 to 23) planting date groups for combined site years. Early/mid planting dates resulted in greater maximum yields. According to the yield-density model, true yield maximization did not occur for any planting dates and site years within the range of plant densities tested in this field study. Soybean economic optimum seed densities (EOSDs) were much lower than predicted plant densities that maximized yield. Soybean EOSDs were identified as 492,000 and 314,000 seeds ha-1 by marginal cost analysis for early/mid and late/very late planting, respectfully. These values were sensitive to changes in soybean grain price and seed cost. Thus, growers need to adjust EOSDs for changes in price and cost. A combined analysis of soybean yields from both experiments using similar target plant densities determined that a significant negative linear relationship existed between soybean yield and planting date. The greatest soybean yields resulted from early planting and declined by 16 kg ha-1 for each one-day delay in planting from Apr 27 to June 16. However, yield responses varied among site years. The overall recommendation from this study would be to plant soybeans during the month of May at a profit-maximizing seed density, accounting for fluctuating grain price and seed cost.

This book was released on 1979 with total page 180 pages. Available in PDF, EPUB and Kindle. Book excerpt: Two experiments were conducted in the field to study the effects of soil moisture and atmospheric conditions on the water status of soybeans. Leaf diffusive resistance at midday, and leaf water potential early in the morning and at midday correlated with soil moisture and atmospheric parameters. The atmospheric parameters studied were: solar radiation, potential evapotranspiration, pan evaporation and maximum air temperature. In addition leaf temperatures were correlated with leaf diffusive resistance. Atmospheric conditions explained the variations of non-stressed plants better than in the stressed plants in 1977 were explained better than in 1978. Probably factors associated with limited volume of soil, and different soil structure inside the soil containers used in 1978 were the reason for those variations of results. The highest yields were obtained from plants not stressed during the entire season. Treatments A (water stress initiated during the flowering), B (water stress initiated during early pod formation), and C (water stress initiated during later pod filling) reduced A and the control were the same. However, the seeds on plants of treatments B and C were significantly smaller. Stress applied during the late pod filling stage produced the smallest seeds. Information obtained from this experiment illustrated two points: (1) the importance of studying plant water status under natural environmental conditions, and (2) water stress during late pod filling is more deleterious on soybean yield than water stress imposed at any other stage.
