Calibration and validation of a soil water simulation model (WaSim) for field grown Amaranthus cruentus
A water simulation model (WaSim) to simulate the growth and development of Amaranthus cruentus as well as the components of water balance for a typical sandy-clay-loam soil of Akure has been described. Dry season experiments were carried between January and March of 2005 and 2006. Amaranthus seeds were established on the field and three irrigation water managements were imposed on the crop to d...
متن کاملInteraction of different irrigation strategies and soil textures on the nitrogen uptake of field grown potatoes
Nitrogen (N) uptake (kg ha-1) of field-grown potatoes was measured in 4.32 m2 lysimeters that were filled with coarse sand, loamy sand, and sandy loam and subjected to full (FI), deficit (DI), and partial root-zone drying (PRD) irrigation strategies. PRD and DI as water-saving irrigation treatments received 65% of FI after tuber bulking and lasted for six weeks until final harvest. Results show...
متن کاملChlorophyll a Fluorescence in Evaluation of the Effect of Heavy Metal Soil Contamination on Perennial Grasses
Chlorophyll a fluorescence gives information about the plant physiological status due to its coupling to the photosynthetic electron transfer chain and to the further biochemical processes. Environmental stresses, which acts synergistically, disturbs the photosynthesis. The OJIP test, elaborated by Strasser and co-workers, enables comparison of the physiological status of plants grown on pollut...
متن کاملA field evaluation of five on-site drug-testing devices.
A field study was performed at two police agencies to evaluate the utility and accuracy of five on-site urine analysis drug-testing devices when used to test driving under the influence (DUI) arrestees. The devices evaluated were AccuSign, Rapid Drug Screen, TesTcup-5, TesTstik, and Triage. Standard workplace screening cut-off concentrations were used and samples were tested for marijuana, coca...
