Characterization of chemical composition, milling properties and carbon dioxide diffusivity resulting from early harvest corn and corn stover
… storage. Corn plants were harvested at different maturity stages in 2009 and 2010 and were quantitatively evaluated in terms of moisture contents, dry matter yields, compositions and processing characteristics of corn and corn stover. The dry matter yield of corn increased rapidly until reaching …

Within-row spacing effect on individual corn plant yield
… spacing. Individual ears were hand-harvested at physiological maturity after recording the distance of each plant to its nearest within-row neighbors. In 2011, there was no significant correlation between each plant’s individual space in the row and grain weight per plant (r = 0.0007 p = 0.60). …

The Ontogeny of Thermoregulatory Abilities in Neonatal Cotton Rats and Montane Voles
Physiological maturity play a vital role in determining thermoregulatory ability in newborn (neonatal) eutherians. Oxygen consumption (stp mlO₂/h*g⁰·⁶⁷) was measured in open chambers at temperatures 20, 25, 30 and 35°C for cotton rat (Sigmodon hispidus) neonates and at temperatures 25, 30 and 35°C …

Light Effect on Seed Chlorophyll Content and Germination Performance of Tomato and Muskmelon Seeds
The stage of maturity of seeds at harvest is an important factor that determines seed vigor. Separating seeds from a seed lot composed of many different stages of development can be difficult especially after maximum dry mass is attained. Separating seeds based on their physiological maturity is …

Effect of Harvest date on seed quality and potential longevity of two Soyabeans(Glycine max(L.)Merr) Varieties
… were measured. Seeds of both varieties attained physiological maturity differed significantly between the two varieties. Onset of germination in fresh seeds was observed at 7 days after podding and in dried seeds at 14 days after podding for both varieties. Seed germination and vigour improved …

Effects of simulated drift of glyphosate, imazethapyr, glufosinate, and imazamox to non-transgenic rice
… panicle differentiation (PD), boot, and physiological maturity growth stages. Spray volume varied proportionally to herbicide dosage and was 15 L/ha for the 6.3% rate and 29 L/ha for the 12.5% rate using 234 L/ha as the target spray volume and were applied with a tractor-mounted …

Effects of maturity and seed size on seed vigor and plant growth in snap bean (Phaseolus vulgaris L.)
Stage of maturity at harvest and relative seed size can affect seed vigor. Greenhouse and field studies were conducted to determine the effect of seed maturity on seed vigor, storability, and subsequent plant growth of four cultivars of snap bean (Topcrop, Provider Black, Provider White, and …

Effects of Corn (Zea mays L.) Stover Removal and Leaching on Soil Test and Whole Plant K Levels in Corn and K Fertilization/High-Input Treatments on Soybean Using Site-Specific Management to Increase Soybean (Glycine max) Production in South Dakota
… may occur following precipitation after corn physiological maturity, presumably through leaching off of corn biomass material. Whole corn plant portions were collected and tested for K+ following rainfall event. The portion of K+ leached relative to total plant K+ concentration indicated that …

Physiological Traits and Quantitative Trait Loci Associated with Nitrogen Use Efficiency in Soft Red Winter Wheat
… NUE was associated with above-ground biomass at physiological maturity were found to be both highly heritable across multiple N supplies. In the second study, two bi-parental mapping populations having a common low ('Yorktown') and two high (VA05W-151 and VA09W-52) NUE parents were characterized …
