Modeling irrigation management strategies to maximize cotton lint yield and water use efficiency
Increasing pumping costs and declining well capacities in the Southern High Plains compel producers to seek irrigation strategies to maximize yield and water use efficiency (WUE), which is the ratio of yield to evapotranspiration (ET). Cotton (Gossypium hirsutum L.) is suited to deficit irrigation using wells ranging from 0.29 to 0.93 L s–1 ha–1 capacity to supply limited, 2.5 mm d–1, to ...

Does skip-row planting configuration improve cotton net return?
Cotton (Gossypium hirsutum L.) growers want information about alternative planting configurations to reduce seed, technology, and other production costs. We evaluated the impact of solid and 2 x 1 skip-row configurations on net returns for cotton grown in 25-, 76-, and 102-cm rows based on yield and fiber quality data from an experiment in adjacent nonirrigated and irrigated fields at Milan, TN. ...

Solid and skip-row spacings for irrigated and nonirrigated upland cotton
Producers of upland cotton (Gossypium hirsutum L.) are interested in alternative row spacings and planting patterns to improve productivity. We conducted factorial experiments for 3 yr in adjacent irrigated and nonirrigated fields at Milan, TN, of cotton grown in 25-, 76- and 102-cm rows, each planted in a solid and 2 x 1 skip-row pattern. Narrower rows and solid plantings tended to close canopy ...

Parameterization and evaluation of the aquacrop model for full and deficit irrigated cotton
Predicting yield is increasingly important to optimize irrigation under limited available water for enhanced sustainability and profitable production. Food and Agriculture Organization (FAO) of the United Nations addresses this need by providing a yield response to water simulation model (AquaCrop) with limited sophistication. In this study, AquaCrop was parameterized and tested for cotton ...
