Abstract:: ... Models provide a quantitative means to evaluate yield response of forage grasses to applied N and water availability. The objective of this analysis was to estimate model parameters (A, b, c) for bermu. dagrasses and bunchgrasses grown at the same location and during the same time period. The logistic equation was used to relate annual dry matter production to applied N for three bermudagrasses [C ...

Abstract:: ... Radiation-use efficiency (RUE, g MJ−¹) has often been used in many crop model equations to estimate total biomass and yield based on cumulative absorbed photosynthetically active radiation. Management practice effects on radiation-use efficiency have not been well documented for grain sorghum [Sorghum bicolor (L.) Moench]. A field study was conducted near Temple, TX to determine plant density and ...

Abstract:: ... Exposure of roots to dry soil may reduce their ability to absorb water when the soil is rewet. We sought to quantify the effects of the duration of exposure to dry soil and the availability of water in deeper soil layers on resumption of water uptake by roots of Sorghum bicolor (L.) Moench following rewetting of the soil. Plants were grown in a greenhouse in pots, half of which were fitted with a ...

Abstract:: ... Fine-textured soils of the Southern High Plains, of which Pullman (fine, mixed, thermic Torrertic Paleustolls) is the dominant series,/ have inherently low water infiltration rates. Pullman soils have a moderately permeable surface horizon overlying and slowly-permeable Bt horizon, which limits deep water penetration, thus hampering water conservation efforts and reducing water-use efficiencies Ib ...
