In the southeastern U.S. Coastal Plains, supplemental irrigation is required to reduce the impact of short‐term droughts and yield‐reducing plant water stress that can occur at least biennially. Sprinkler irrigation is commonly used to water agronomic crops in the region. Microirrigation is typically used for high value fruit and vegetable crops. In recent years and at some locations, microirri...

Optimizing row spacing can potentially improve yields when resources such as light and water are limited. Sugarcane in Louisiana is principally grown on rows spaced 1.8 m apart, but interest planting 2.4 increasing. In this study, we hypothesized that wider would have greater availability. Soil moisture sensors were placed at 15, 30, 45 cm depths treatments: spacings, two varieties (L 01-299 Ho...

Slurry injection below maize seeds is a rather new application technique developed to improve the nitrogen use efficiency of liquid organic manure. To enable the characterization of the spatial and temporal soil mineral nitrogen (SMN) dynamics after slurry injection the present study aims to develop an appropriate soil sampling strategy. Three consecutive experiments were conducted. The first t...

Photovoltaic and solar thermal projects require accurate irradiance data models for the design, assessment, forecasting of power output. For panels collectors installed in arrays, view toward sky ground is restricted by surrounding rows. This paper analyzes impact obstructions on diffuse distribution fixed-tilt addressing insufficient research coverage to date. Irradiance was measured using hig...

The intercisternal spacings between cisternae of dictyosomes of higher plants differ from those of mammalian dictyosomes. In plants, the spacings increase from an average of about 8.0 nm at the forming face to about 14.0 nm at the maturing face. The increase in spacing coincides with the appearance within the intercisternal space of parallel filaments called intercisternal elements. In mammals,...
