KUSLU, Y., U. SAHIN, T. TUNC and F. M. KIZILOGLU, 2010. Determining water-yield relationship, water use efficiency, seasonal crop and pan coefficients for alfalfa in a semiarid region with high altitude. Bulg. J. Agric. Sci., 16: 482-492 A field study was conducted to determine effects of seasonal deficit irrigation on plant dry forage yield and water use efficiency of alfalfa for a 2-year peri...

Gary A. Clark Research Agricultural Engineer Subsurface drip irrigation (SDI) systems deliver water to the root zone of crops using polyethylene drip tubing that is permanently buried below the soil surface. In properly designed and operated systems, little or no wetting of the soil surface occurs, nor is there visual evidence of the system performance. Because SDI systems apply water different...

A fire in an enclosed space, such as a room in a building, is generally called a compartment fire. To prevent the compartment fire, a sprinkler for first-aid fire-fighting is installed in rooms. However, it is difficult to determine the degree to which smoke generation and the fire spreading will be inhibited when sprinklers are on. In particular, demonstrating evacuation behavior assuming an a...

Heat stress is the main challenge for buffaloes as animals. The wallow in water to abate heat load. use of sprayed from sprinklers/soakers or misters has been most common method cooling dairy animals during summer. This study aimed evaluate effects a strategy on milk yield, physiological, behavioral and biochemical activities buffaloes. Thirty aged (4-7) years old were used. divided into two gr...

Agricultural development with horticultural crops on dry land is one of the government's efforts to increase productivity so that new paddy fields are created in Bayan area. Noting infiltration capability and its classification important factors needed irrigation planning support agriculture, it necessary conduct field research this matter. This study aims determine characteristics trend can be...

The success of Ilex paraguariensis cutting can be affected by the population origin, as well genotype and rooting environment. Therefore, objective this search was to test vegetative propagation I. cuttings from two populations their genotypes inserted in environments. tested were Três Barras (TB) Urupema (UR), both Santa Catarina state, selecting seven each. After collecting cutting, evenly di...

Water availability is the major limiting factor of the functioning of deserts and grasslands and is going to be severely modified by climate change. Field manipulative experiments of precipitation represent the best way to explore cause-effect relationships between water availability and ecosystem functioning. However, there is a limited number of that type of studies because of logistic and co...

Irrigation has become commonplace for residential homeowners desiring high quality landscapes in Florida. The goal of this project was to document irrigation system uniformity in Central Florida and to quantify distribution uniformity of residential sprinkler equipment under controlled conditions. The catch-can testing procedure used was a modified version of both the American Society of Agricu...

Wave lensing produces the highest level of transient solar irradiances found in nature, ranging in intensity over several orders of magnitude in just a few tens of milliseconds. Shallow coral reefs can be exposed to wave lensing during light-wind, clear-sky conditions, which have been implicated as a secondary cause of mass coral bleaching through light stress. Management strategies to protect ...
