abstract infiltration is a significant process which controls the fate of water in the hydrologic cycle. the direct measurement of infiltration is time consuming, expensive and often impractical because of the large spatial and temporal variability. artificial neural networks (anns) are used as an indirect method to predict the hydrological processes. the objective of this study was to develop ...

The impact of global climate change is a challenge to the sustainability many ecosystems, including soil systems. However, performance properties under future was rarely assessed. Therefore, this study carried out evaluate selected processes using an agri-environmental modeling approach Sri Lanka. Agricultural Production Systems Simulator (APSIM) model used simulate and plant-related recent pas...

Thirty lactating Holstein Friesian cows were used in a three treatment randomised block design experiment to investigate the influence of degree of grass wilting prior to ensiling on animal performance and energy utilisation. The three forage treatments were produced from perennial ryegrass swards either ensiled directly or mown, conditioned, spread and tedded to ensure rapid wilting, and ensil...

The effects of wilting on the fate of proline and on the rates of nonprotein proline formation and utilization have been determined in excised bean leaves. Wilting did not alter the fate of exogenously added (14)C-l-proline (2 mm) in either non-starved leaves (from plants previously in the light) or starved leaves (from plants previously in the dark). The fate of proline in nonstarved leaves wa...

the aim of this study was to investigate relationships between soil properties and plant species to determine the most effective factors separating vegetation communities in rineh rangeland. three stratifying variables were selected including slop, aspect and elevation. the study area was partitioned by combining these classes to generate homogenous units. 1m2 quadrates were located at sampling...

To ensure the selection of wheat genotypes that are resilient to future climatic conditions, with drought already being most significant and acute problem in many areas, twenty winter cultivars were tested for stress tolerance from beginning stem elongation (DC 30; Zadoks decimal codes) 49 days (until stage grain development, DC 73–75) within an automatic phenotyping platform. The control plant...

This research examines the effects of two irrigation strategies on water use efficiency and fruit yield components ‘Royal Gala’ ‘Brookfield apple orchards in south-central Chile. The study was carried out during 2008–2009 2009–2010 growing seasons at sites. A randomized block experimental design established with application treatments: theoretical volume required by plant (T1) farm protocol (T2...
