Changes in gene expression under water stress in the flag leaf and seed head during the grain-filling stage of two spring wheat cultivars
(2018-05)
Drought poses severe limitations on crop production. Therefore, drought tolerance mechanisms need to be better understood to select, modify and recommend certain cultivars of wheat. The grain filling stage of wheat development ...
Remote sensing application in biomass crop production systems in Oklahoma
(2013-12)
This study was conducted to evaluate the combined effects of nitrogen and cropping systems on biomass yield and quality and to describe the spatial variation of biomass yield, soil carbon and nitrogen within a switchgrass ...
Evaluating capabilities of novel warm-season crops to fill forage deficit periods in the Southern Great Plains
(2019-12)
Low nutritive value of perennial grasses during mid-late summer limits stocker cattle production in the Southern Great Plains (SGP). Our objectives were to explore annual crop species that might fit as a summer forage, and ...
Limits to winter wheat (Triticum aestivum L.) productivity and resource-use efficiency in the southern Great Plains
(2015-07)
Wheat yields have been stagnant at ~2 Mg ha-1 for 30-yr in the southern Great Plains and evidences suggest yields are below the potential (Yw). Our objectives were to quantify the wheat Yw and determine its meteorological ...
Study of the diversity, inbreeding potential, and sward heritability of switchgrass
(2011-12)
Scope and Method of Study: Study the diversity of 56 genotypes of switchgrass from different regions of the US using AFLP. Study the heritability of two populations of Switchgrass (SL-93 C2 and NL-94 C2 ) in swards. ...
Genetic analysis of inheritance and linkage of molecular markers, and variability of adaptive, morphological and reproductive traits in common bermudagrass [Cynodon dactylon (L.) Pers.]
(2015-12)
Common bermudagrass [Cynodon dactylon (L.) Pers.] is economically and environmentally the most important member among Cynodon species because of its extensive use for turf, forage and soil erosion control in the world. ...
Genetic basis of nitrogen use efficiency and its application in wheat breeding
(2018-07)
Nitrogen is the major limiting factor in crop production worldwide, and N is now the single largest input cost for many crops including wheat. Nitrogen use efficiency (NUE) is a complex trait, and as many as 25 genes have ...
Increasing yield of late-planted soybean through management practices in the Southern Great Plains
(2014-08)
Increased soybean commodity prices and high-yielding cultivars have instigated producers to expand soybean production outside traditional regions. Introduction of soybean to relatively new areas such as the Southern Great ...
AFLP genetic variation, inbreds development, and QTL localization for plant height in lowland switchgrass
(2014-12)
Switchgrass (Panicum virgatum L.) has gained wider attention due to its recognition as a model herbaceous crop species for bioenergy production. The objectives of this research were to analyze genetic variation among and ...
Genetic diversity among hard red winter wheat cultivars and experimental lines and their association with water limitation
(2017-12)
The effect of water limitations on Hard Red Winter Wheat (HRWW) production is a major concern for the wheat industry throughout the Southern Great Plains. Average HRWW yield was compared between irrigated and rainfed ...
