Intermittent Irrigation Effects on Barnyardgrass Weed Control and Rice Yield

Discovery and small RNA profile of Pecan mosaic-associated virus, a novel potyvirus of pecan trees

A novel potyvirus was discovered in pecan (Carya illinoensis) showing leaf mosaic symptom through the use of deep sequencing of small RNAs. The complete genome of this virus was determined to comprise of 9,310 nucleotides (nt), and shared 24.0% to 58.9% nucleotide similarities with that of other Potyviridae viruses. The genome was deduced to encode a single open reading frame (polyprotein) on t...

Recovery and Partitioning of Nitrogen from Early Spring and Midsummer Applications to Pecan Trees

Effective nitrogen (N) management promotes consistent and abundant pecan [Carya illinoinensis (Wangenh.) C. Koch] production while minimizing waste. Recovery and partitioning characteristics of N potentially affects N management decisions; for this reason, we report certain N characteristics exhibited by trees in a bearing ‘Pawnee’ orchard. Nitrogen was applied prebudbreak (PBB) as a single 10 ...

Increasing Returns and Economic Efficiency

This paper argues that, from the viewpoint of Pareto optimality, the industries with increasing returns are under-expanded relative to those without increasing returns and those with higher degrees of increasing returns are under-expanded relative to those with lower degrees. Ignoring administrative and indirect (such as rent-seeking) costs, subsidies on goods produced under conditions of (high...
