Evaluating the Response of Modern Soybean Cultivars to Commercial Foliar and Soil-applied Nitrogen Fertilizers
Author: John Clayton Craft
Publisher:
ISBN:
Category : Nitrogen fertilizers
Languages : en
Pages : 99
Book Description
Increasing soybean [Glycine max (L.) Merr.] seed yield has been a major objective for producers, and supplementing soybean nodulation with synthetic nitrogen (N) has been suggested as a possible management strategy to maintain or improve yield in environments with high yield potential (>4500 kg ha-1). However, there is limited information available for the use of commercial foliar N products in soybeans in Ohio. The objectives of this research were to (i) examine the effect of foliar and soil applied N on soybean growth and development for several soybean cultivars; and (ii) quantify the seed yield and quality response to various soil and foliar N treatments across soybean cultivars with different maturity groups. Two studies were conducted with six experiments at two Ohio locations across the 2016 and 2017 growing seasons. Soybean growth, nodulation, and maturation rates were evaluated throughout the season, and seed yield and quality were measured after physiological maturity. Data was analyzed using SAS 9.4, and means were separated using Fisher’s protected LSD. Single DF contrasts were conducted to compare soybean relative maturity groups across cultivars. Within each experiment (site-year), maturity date, yield, and seed quality varied among cultivars. The maturity group II cultivars produced to have lower seed protein and matured more quickly than the maturity group III cultivars across site-years and studies. The application of N treatments did not increase maturity date, yield, nor seed quality across all the site-years (experiments), or maturity groups. This research suggested that soil and foliar N at low application rates has minimal effect on soybean growth and development, and may not be an advisable practice for Ohio producers with similar environments as used in these studies.

Reaction of Soybean Cultivars to Waterlogged Soil

Book Description
Irrigating soybean prior to an extensive rain can result in waterlogged soil that may cause root damage and plant death. Some soybean cultivars tolerate waterlogged soils. The objective of this study was to evaluate tolerance of soybean cultivars to waterlogged soils at different soybean growth stages and flood durations. A selection of maturity group IV soybean cultivars was screened for flood tolerance in the field. Five cultivars were selected for variations in tolerance to waterlogged soil conditions. An experiment was conducted to determine the response of these cultivars to waterlogged soil for 192 h at thee growth stages (V5, R1, and R5). A second experiment was conducted to determine the response of these cultivars to flood for 0, 48, 96, 144, and 192 h at the R1 stage of growth. A significant interaction was found between cultivars and growth stage flooding when exposed to waterlogged soil. The greatest yield suppression from waterlogged soil occurred at the R5 growth stage compared to V5 and R1. Soybean yield suppression due to waterlogged soil was least when flood was applied at V5 compared with the R1 and R5 stages of growth. Flood duration had a significant negative effect on soybean yield (P = 0.0012). When averaged across years and cultivars, soybean yields declined 310 kg ha-1 after being flooded for 192 hours at bloom compared to non-flooded checks. Significant interactions between cultivar and duration were not found.
