There is a need for an accurate method to calculate and to measure crop water use on real‐time.
We implemented a system that combines knowledge of crop water use and available …

Pre‐plant soil NO − 3 –N tests and petiole NO − 3 –N analysis are bases for Upland cotton (Gossypium
hirsutum L.) N management in the western USA. Alternative approaches include …

It is estimated that 20% of cotton producers in the Texas High Plains use the strip tillage
practice of planting cotton (Gossypium hirsutum L.) in residues of chemically terminated winter …

Radiometric data can be useful to determine the impact of field heterogeneity, irrigation, and
fertilization on plant water and N use. A 2‐yr (1998–1999) study was conducted on the …

Crop irrigation with subsurface drip (SDI) is increasing in the semiarid Texas High Plains (THP).
Information on drip-tubing positioning, irrigation strategies, and wetted soil area is …

Pearl millet [Pennisetum glaucum (L.) R. Br.] production in the West African Sahel is constrained
by low, erratic rainfall and low soil nutrient (particularly P) availability. Outdoor pot and …

Measurement of leaf area index (LAI) is useful for understanding cotton (Gossypium hirsutum
L.) growth, water use, and canopy light interception. Destructive measurement is time …

Landscape variability associated with topographic features affects the spatial pattern of soil
water and N redistribution, and thus N uptake and crop yield. A landscape-scale study was …

Nitrogen recommendations for Upland cotton (Gossypium hirsutum L.) in the western USA
are based on spring soil NO − 3 –N tests. In‐season monitoring of plant N status is another …

Field heterogeneity in soil texture and site elevation (SE) may affect crop water and N use. A
2‐yr (1998–1999) study was conducted on the Texas High Plains to determine the …
