Center pivot sprinkler systems can apply chemicals as well as water to crops. This study was conducted to determine the horizontal and vertical distribution of an insecticide applied with a center pivot irrigation system to a corn crop. The experimen

Summer squash (Cucurbita pepo L. cv. Dixie hybrid) were grown in drainage lysimeters under closely controlled and monitored soil water regimes. Variables included three irrigation treatments, three growing seasons, and two soil types. Marketable frui

Florunner peanuts (Arachis hypogaea L.) were subjected to 35 and 70-day drought periods during several growth stages (days after planting). Drought conditions were maintained by the use of automatic rainout shelters covering groups of drainage lysime

Tracking the nutrient element content of peanut leaves over the entire fruiting season revealed significant changes in certain essential elements during short periods. These short‐term changes may be more influential on yield than the general chang

Droughty conditions are implicated in causing low yields, poor grades and germination, and an increased incidence of aflatoxin in the peanut (Arachis hypogaea L.). However, very little is known as to when in the growth cycle drought is most critical.

Two snap bean cultivars, ‘Galagreen’ and ‘Eagle’, were grown in rainfall sheltered irrigation plots as spring and fall crops. Pod yield of snap beans irrigated when the soil water tension reached 25 kPa (0.25 bar) averaged 11.9 MT/ha. Applica

PRE-CAST concrete flushing gang slats with tubes (6.9 cm diameter) formed in the concrete immediately below each slot were tested under laboratory and field conditions. Water velocity through the slats increased from 0.76 m/s at 1% slope to 0.90 m/s

Three peanut (Arachis hypogaea) varieties were maintained at soil water levels ranging from moderately wet to very dry. Pod yield and quality were significantly reduced in treatments receiving less than about 30 cm of water during the growing season.

Seed of 11 cultivars of snap bean, Phaseolus vulgaris L., were separated by aerodynamic properties in a vertical air column. Seed physical characteristics associated with air column separation were weight, density, volume, diameter, and length. The s
