- Abstract:
- ... Two experiments were conducted to evaluate the growth and flowering responses of greenhouse-grown French marigold (Tagetes patula L. ‘Janie Deep Orange’) to two non-composted broiler chicken litter-based organic fertilizers, 4-2-2 and 3-3-3, and one commonly used synthetic controlled-release fertilizer, 14-14-14. In both experiments, fertilizer 4-2-2 was applied at four rates of 1%, 2%, 4%, and 6% ...

- Abstract:
- ... A 2-yr field study was conducted during 2007 and 2008 at Stoneville, MS, to determine the effect of twin-row (two rows 38 cm apart on 102-cm beds) and single-row (on 102-cm beds) patterns and glyphosate POST applications with and without fluometuron ++ S-metolachlor PRE on cotton canopy closure, weed control, and lint yield in two cultivars (‘‘DP117B2RF’’, early maturity, hairy leaf; ‘‘DP164B2RF’’ ...

- Abstract:
- ... A field experiment was conducted to evaluate the effect of harvest time and drying on Japanese cornmint (Mentha canadensis L.) cultivars Arvensis 2 and Arvensis 3 to optimize technology. Biomass yields were comparable to those reported in the literature. Arvensis 2 had greater oil content (0.78%) than Arvensis 3 (0.59%), while Arvensis 3 had higher concentrations of (-)-menthol (71.9%) and (-)-men ...

- Abstract:
- ... The fatty acids (FA) composition of sunflower (Helianthus annuus L.) determines its uses and health effects on humans, while oil content determines the price paid to producers. The hypothesis of this study was that agronomic factors (genotype, planting date, and N rate) will affect total saturated fatty acid (TSFA) concentration and oil content of sunflower. Additionally, Mississippi-grown sunflow ...

- Abstract:
- ... The last effective boll population (LEBP) is the basis for many cotton (Gossypium hirsutum L.) management decisions such as defoliation timing. The objective of this research was to determine the last effective boll population based on first position bolls for both ultranarrow row cotton (UNRC), grown in rows spaced 25 cm or less, and conventional cotton (CONC) grown in rows spaced 96 to 102 cm. E ...

- Abstract:
- ... An inverse relationship between soybean [Glycine max (L.) Merr.] seed protein and oil concentration is well documented in the literature. A negative correlation between protein and yield is also often reported. The objective of this study was to determine the effect of high rates of N applied at planting on seed protein and oil. Nitrogen was surface-applied at soybean emergence at rates of 290 kg ...

- Abstract:

Field studies were conducted at Stoneville, MS (33°26′ N lat) to determine effect of weed management on yield and net return from maturity group (MG) IV and MG V cultivars grown in the ESPS in narrow rows (NRs; 50-cm width) a ...

- Abstract:
- ... Sediment and its associated pollutants entering a water body can be very destructive to the health of that system. Best Management Practices (BMPs) can be used to reduce these pollutants, but understanding the most effective practices is very difficult. Watershed models are the most cost-effective tools to aid in the decision-making process of selecting the BMP that is most effective in reducing t ...
