Weed-suppressive rice cultivars have the potential to reduce heavy reliance on synthetic herbicides in rice production. However, the economics of using weed-suppressive rice cultivars in conventional rice systems have not been fully evaluated. This s

Weed control in rice is challenging, particularly in light of increased resistance to herbicides in weed populations and diminishing availability of irrigation water. Certain indica rice cultivars can produce high yields and suppress weeds in convent

Pediatric L-HLTx recipients are at risk for developing PTLD with the lung being a primary site of disease. We hypothesized that BALF is a better sample than peripheral blood for measuring EBV DNA load in this high-risk population. Archived BALF speci

Rice production in Arkansas usually involves intensive tillage. No-till rice has been studied, but the focus has been limited to impacts on yields and per acre returns. This study uses mixed integer programming to model optimal machinery selection an

No-tillage systems are used to control soil erosion and water runoff on sloping cropland, but these systems, which rely heavily on herbicides and commercial fertilizers, may contribute to nutrient and herbicide contamination of water, air, and other

Cover crops are important components of sustainable agricultural systems. They increase surface residue and aid in the reduction of soil erosion. They improve the structure and water-holding capacity of the soil and thus increase the effectiveness of
