- Abstract:
- ... A 2-yr study was conducted to assess the effects of early and late planting on six soft red winter wheat (Triticum aestivum L.) cultivars. The purpose was to determine if increased flexibility in planting date is possible for modern wheat cultivars grown in the Middle Atlantic states. Wheat was planted 2 wk prior to, on, and 2 wk after the recommended fly-free planting date at Clarksville (Piedmon ...

- Abstract:
- ... There is increasing interest in growing determinate soybean [Glycine max (L.) Merr.] in the northern USA because of their yielding ability and lodging resistance. These cultivars are approximately half as tall as indeterminate cultivars. The objectives of this study were to estimate the heritabilities of days to R1 and R8, and plant heights at R1 and R8; and to evaluate the relationships among the ...

- Abstract:
- ... No-tillage (NT) crop production practices have been continuously maintained at four sites in Ohio for more than 25 yr. The original experiments involving NT were designed to determine how much tillage was required to produce crops with satisfactory yields and how tillage and rotation interact to effect crop yields, especially corn (Zen mays L.). Long-term effects of NT on crop yields and soil prop ...

- Abstract:
- ... Productivity of nonlegume crops depends partly on nitrate uptake and reduction. To study the nitrate assimilation pathway of plants, the herbicide chlorate has been exploited as an analog of nitrate. Marked variations in visible leaf chlorosis among 15 soft red winter wheat (Triticum aestivum L.) seedlings exposed to 120 μM chlorate were reported by others. From their study, we selected three chlo ...

- Abstract:
- ... Sweetpotato virus disease (SPVD) is a disease syndrome due to the dual infection and synergistic interaction of sweetpotato chlorotic stunt crinivirus (SPCSV) and sweetpotato feathery mottle potyvirus (SPFMV). SPVD causes up to 98% yield loss in East Africa. Uganda’s sweetpotato breeding program released six sweetpotato cultivars with moderate to high levels of field SPVD resistance in 1995. A mul ...

- Abstract:
- ... Vast areas of semiarid rangelands in western USA are severely degraded and infested with troublesome weeds such as cheatgrass (Bromus tectorum) and medusahead rye (Taeniatherum asperum). Reseeding with appropriate plant materials that are adapted to the site and competitive enough to replace existing undesirable vegetation is often the most plausible way to reclaim such sites. Unfortunately, many ...

- Abstract:
- ... Rhizomania, caused by Beet necrotic yellow vein virus (BNYVV) and vectored by the soilborne fungus Polymyxa betae Keskin, is one of the most economically damaging diseases affecting sugar beet (Beta vulgaris L.). The virus likely originated in Europe and was first identified in California in 1983 (1). It has since spread among American sugar beet production regions in spite of vigorous sanitation ...

- Abstract:
- ... Seed color of flax (Linum usitatissimum L.) is used in Canada to identify the two main market types. Traditional, high linolenic acid flax must have brown seed, while solin or zero linolenic acid flax must be yellow-seeded. The objective of this study was to determine the allelic–gene relationship of the dominant yellow gene, the variegated recessive gene, and various spontaneous and unknown reces ...
