Evaluating Physiological Responses Of Ten Alfalfa (Medicago Sativa Subsp. Falcata) Germplasm To Drought Treatments, Austin Hanson
Evaluating Physiological Responses Of Ten Alfalfa (Medicago Sativa Subsp. Falcata) Germplasm To Drought Treatments, Austin Hanson
The Journal of Undergraduate Research
Alfalfa is the most widely produced perennial forage legume in North America. However, its use in the semiarid northern Great Plains is limited due to poor stand establishment and persistence under drought condition. The development of drought-tolerant alfalfa cultivars is of great need. Some Medicago sativa subsp. falcata populations have demonstrated promising drought resistance when compared to M. sativa. Morphological and physiological mechanisms play a critical role in drought tolerance by influencing seedling survival, stand establishment and drought recovery. Assessment of variability in physiological responses to drought among germplasm lines to drought is necessary for developing cultivars with improved drought …

Kansas Agricultural Experiment Station Research Reports
Corn hybrid development with a focus on drought tolerance has emerged in recent years, and producers have questions about their yield performance across a range of plant populations. A two-year study was conducted to determine the yield of corn hybrids across several plant populations. Corn hybrids responded differently in 2013 and 2014. In 2013, a lower yield environment occurred. The hybrid with drought tolerance had the greatest yield of 95 bu/a at a plant population of 21,500 plants/a, whereas the non-drought-tolerant hybrid’s greatest yield was 90 bu/a at a plant population of 13,500 plants/a. In 2014, the yield environment was …

Drought-tolerant technologies have become popular in hybrids for low-yielding corn environments across central and western Kansas and are marketed for their ability to produce higher grain yields with less water. The objective of this study was to compare water use, yield, and water use efficiency (WUE) of two types of drought-tolerant (DT) corn hybrids and a high-yielding non-DT hybrid. Water use and yield of two DT and one non-DT, high-yielding hybrid were compared in both dryland and irrigated situations. The average yield for the irrigated corn was 217 bu/a, and the average was 127 bu/a in dryland, representing a yield …
