A field study conducted over five growing seasons (2013-2017) assessed the effect of long-term fertilization history and crop rotation on growing season nitrous oxide (N2O) and carbon dioxide (CO2) emissions, wheat yield, wheat N uptake, N2O emission inten...
The objective of this research was to compare the performance of conventional urea to enhanced efficiency fertilizers (ESN, eNtrench-treated urea and SuperU), banded in the fall or sping, with respect to wheat yields (at 0, 0.5, 1.0 and 1.5 times the recom...
We initiated experiments in 2015 and 2016 at different locations in Indiana to generate field data to test the hypothesis that increase in NRE will lead to significant reduction of N2O during corn production. Our specific objectives were to assess the rel...

Sorghum is an important food crop for millions of people in Africa and Asia. Whole genome re-sequencing of sorghum EMS mutants exhibiting an alkali spreading value (ASV) phenotype revealed candidate SNPs in Sobic.004G163700 and Sobic.010G093400. Comparativ...
There is an urgent need to accelerate energy crop development for the production of renewable transportation fuels from biomass. Greater knowledge of factors that influence crop growth and development is required to improve the breeding development pipelin...
The Uniform Soybean Tests, Northern Region, have been in place since 1941. The tests evaluate yield, disease resistance, and quality traits of public breeding lines from northern states of the U.S. and Canadian provinces. The purpose of The Uniform Soybean...
Open-path Fourier transform infrared spectroscopy (OP-FTIR) has often been used to measure hazardous or trace gases from ‘hot’ point sources (e.g., volcano, industrial or agricultural facilities) but seldom used to measure greenhouse gases (GHGs) from fiel...
Subirrigation is the application of irrigation water below the ground surface to raise the water table to within or near the root zone. In areas with subsurface tile drainage, the same drains that remove excess water during wet periods can be used to provi...
The soil landscape rule-based model was used to disaggregate the soil map units by exploiting information in the Busia soil map legend and the map unit descriptions. These descriptions were used to generate rules that were applied to a fuzzy soil class map...

To determine specific crop suitability ratings for Busia area, decision matrices developed by Rachilo and Michieka (1991) were used to generate crop suitability classes for each soil map unit. Land suitability is the fitness of a given tract of land for a...
