Coal Char Affects Soil Ph To Reduce Ammonia Volatilization From Sandy Loam Soil, Dinesh Panday, Maysoon M. Mikha, Bijesh Maharjan
Coal Char Affects Soil Ph To Reduce Ammonia Volatilization From Sandy Loam Soil, Dinesh Panday, Maysoon M. Mikha, Bijesh Maharjan
Department of Agronomy and Horticulture: Faculty Publications
Ammonia (NH3) volatilization loss adversely affects N availability in soil-plant systems, reduces crop yield, and negatively impacts environment. Char (coal combustion residue), which contains up to 293 g kg−1 total C by weight, has been shown to reduce NH3 volatilization due to its considerably high surface area and cation exchange capacity. The NH3 loss can be greatly affected by a shift in soil pH or urea hydrolysis. A 21-d laboratory study was conducted to evaluate the effects of char on soil pH, N transformations, and subsequent NH3 volatilization in sandy loam soil. Two …

Department of Agronomy and Horticulture: Faculty Publications
Despite widespread adoption of dicamba/glyphosate-resistant (DGR) soybean [Glycine max (L.) Merr.] in Nebraska and across the United States in recent years, economic information comparing herbicide programs with glufosinate-resistant (GLU-R) and conventional soybean is not available. The objectives of this study were to evaluate weed control efficacy, crop safety, gross profit margin, and benefit/cost ratios of herbicide programs with multiple sites of action in DGR, GLUR, and conventional soybean. Field experiments were conducted in 2018 and 2019 at three irrigated and two rain-fed locations across Nebraska, for a total of 10 site-years. Herbicides applied pre-emergence (PRE) that included herbicides with …

Climbing beans play a central role in food security of rural households in the densely populated highlands of East and Central Africa. Soil fertility degradation and the lack of nutrient inputsare major limitations to yield of beans and other crops. We conducted field trials in Northern Rwanda in Kinoni and Muko villages to evaluate the effect of mineral N, P, and K fertilizers (both alone and in combination) and farmyard manure on nitrogen fixation and grain yields of climbing bean insmallholder farmers' fields. The trials were laid down in a randomized complete block design with seven replicate blocks in each …

Push-Pull Technology Improves Maize Grain Yield And Total Aboveground Biomass In Maize-Based Systems In Western Kenya, Pierre Celestin Ndayisaba, Shem Kuyah, Charles Aura Odhiambo Midega, Peter Njoroge Mwangi, Zeyaur Rahman Khan
All Peer-Reviewed Publications
Push-pull is one of the sustainable intensification technologies for the control of stem-borers, striga weed and fall armyworm. Even though the effectiveness of push-pull in addressing these constraints has been evaluated under different agro-ecological conditions and on research stations, performance of the technology relative to other common maize-based cropping systems in farmers’ fields and the impact of the push-pull age is not yet understood. We hypothesized that, a) maize grain yield and aboveground biomass from push-pull system is higher than other common maize farming systems; b) duration of use of push-pull, and climatic conditions have an influence on its efficacy; …

Growth, Physiological And Biochemical Responses Of Winged Bean (Psophocarpus Tetragonolobus) Towards Different Shade Levels, Murthazar Naim Raai
Growth, Physiological And Biochemical Responses Of Winged Bean (Psophocarpus Tetragonolobus) Towards Different Shade Levels, Murthazar Naim Raai
Student Works (2020-2029)
Ambiguous evidence suggests that shade could regulate the indeterminate growth habit of winged bean (Psophocarpus tetragonolobus), an underutilized protein-rich legume from the tropics. This study was conducted to examine the effects of three different shade levels, including 60% (heavy shade), 30% (moderate shade), and 0% (as control) on 25 traits associated with morphological features, photosynthetic and agronomic characteristics of winged bean. The shade-house experiment was conducted using a completely randomized design. Collectively, approximately 80% of the studied variables displayed significant differences (P< 0.05) between at least two shade treatments. Shading generally showed the most pronounced effect on the physiological traits of the legume, whereby the stomatal conductance, photosynthetic and transpiration rates differed significantly (P< 0.05) among plants for all treatments. Overall, non-shaded plants were observed to have superior growth and physiological responses than the shaded plants, especially being significantly taller with higher stomatal conductance, photosynthetic and transpiration rates. Interestingly, the moderately shaded plants exhibited the highest yield per plant (28.9 g �} 1.47), which significantly differed from the non-shaded (23.8 g �} 1.06) and heavily shaded (21.4 g �} 1.48) plants. These findings suggested that winged bean plants can adapt to partial shaded conditions or canopy cover, making it a potential nitrogen-fixing cash crop which can be planted together with fruit and oil trees in commercial plantations. Given that there were no significant differences between the moderately shaded and heavily plants with respect to their seed protein content (P>0.05), this project also demonstrates that winged bean can grow and yield well while maintaining its protein content …
