Abstract Timely and quality planting of soybean is important to achieve maximum yield potential. Wet spring soil conditions rain frequently shorten the time for farmers plant crops within optimal conditions. New planter technology has been introduced that enables their fields faster more precisely than with traditional planters. Large plot field studies were conducted in Indiana from 2015 2017 ...

Decreased agricultural diversity from extensive use of the corn (Zea mays L.)- soybean (Glycine max (L.) Merr.) rotation and occasional inclusion spring wheat (Triticum aestivum L.), has threatened cropping system sustainability. Using specialty oilseeds crops to extend corn-soybean might improve yields promote We tested whether corn, soybean, would be improved in a following oilseed versus or ...

Management Contributions to Recent Trends in U.S. Agricultural Yields” According to Lobell and Asner (1), the atypical summer cooling trend from 1982 to 1998 increased U.S. yields of corn and soybeans during the same period. However, three potential problems with their analysis bring their results and conclusion into question. The first concern relates to selective use of data in (1). To estima...

Soybean (Glycine max L.) is considered as one of the major sources of oil and protein. In this study, the effects of vermicompost (VC) and sulfur (S) on soybean photosynthesis responses, yield, and grain quality were studied. To this end, a split-plot design field experiment based on randomized complete blocks with nine treatments and three replications was conducted in Aligudarz city Lorestan ...

Timing, intensity, and frequency of biomass removal PREDICTING YIELD LOSS IN affects soybean yield. Yield reduction is less sensitive INDETERMINATE SOYBEAN FROM to biomass removal during vegetative growth because soybean can develop new leaf area that can compensate POD DENSITY USING SIMULATED for temporarily reduced assimilatory capacity. Singer DAMAGE STUDIES (2001) reported that yield reduct...

The problems of low soil fertility resulting from continuous monocropping, crop residue removal and limited fertilizer use represent key challenges to produce surplus food for the ever increasing population of Ethiopia. However, the practices of crop rotation and integrated sources of fertilizer uses could potentially improve soil fertility and productivity. In 2012 and 2014, soybean with diffe...

The study was aimed to determine the effect of soil ameliorant and inorganic fertilizers on nodulation and yield of some soybean varieties. Study was conducted under greenhouse condition in acid soils. Results revealed that all the tested varieties were compatible with native rhizobium at both study areas and showing the formation of nodules. A positive correlation was reported between the numb...
