This work presents the field implementation of an intelligent irrigation controller, applied to grapevine crops. The proposed irrigation system includes the moisture measurements and the development of an intelligent control system, in order to maintain the moisture level around a set value. Moisture reference value for different irrigation treatments, such as water stress or field capacity, is...

Sweet corn (Zea mays L.) producers desire high yields and high sugar content in the endosperm. High irrigation levels result in high yield, but their effect on sugar content is unclear. The effects of two irrigation levels, standard and stressed on endosperm sugar content were evaluated using three sugary1 hybrids over 2 years. No significant differences were found among the treatments when ave...

Shortage and salinity of irrigation water are two major constraints that influence rapeseed production in arid and semi-arid regions of central and southern Iran. In this study, effects of deficit irrigation with different salinity levels and planting methods (in-furrow and on-ridge) as strategies for coping with water and salinity stresses on yield and yield quality of rapeseed were invest...

A comparison of decision rules has been made for case studies of corn production using subsurface drip irrigation under three agricultural management practices (no irrigation, uniform irrigation, and variable rate irrigation). The uniform irrigation strategy appeared to perform the best than the other two management practices under different risk scenarios.

To improve the management of irrigation district is a key to develop water-saving agriculture. Based on the basic principles of water-saving irrigation, and using the method of Modified Penman Monteith and water balance equation, The system of irrigation management and decision support based on WEBGIS was developed,which is according to the soil moisture, crop growth status, meteorology change ...

BACKGROUND The established treatment for bacterial arthritis of the knee joint is arthroscopic surgery with irrigation and debridement. The aim of this article is to summarize the relevant data in treating bacterial arthritis of the knee joint, and based on these findings to present a novel irrigation suction system, tested in a cadaver study, as an additional tool in the postoperative treatmen...

An experiment was performed at the Miyandoab Agricultural Research Station to study yield and water use efficiency of furrow and tape irrigation systems in one-row and two-row planting patterns, and to investigate density of grain corn SC704. The experimental design was a completely randomized block arranged in Strip Split Plots with three replications in 2010. Irrigation treatments were applie...

A simulation model was developed to estimate the effect of deficit irrigation upon crop yield. The model was designed to provide relative yield estimates for numerous combinations of irrigation system, crop growth and irrigation management parameters. A daily soil moisture balance was used to predict evaporation and transpiration from which crop yields were estimated. Gross irrigation water req...

BACKGROUND: Deficit irrigation strategies were effective in saving volume of water. Potassium is an essential nutrient that affects most of the biochemical and physiological processes are involved in plant resistance to biotic and a biotic stresses. OBJECTIVES: This study was conducted to assess effect of different pattern of irrigation and several source...

Although rainfall in the United States Mid-South is sufficient to produce corn (Zea mays L.) without irrigation in most years, timely irrigation has been shown to increase yields. The recent interest in ethanol fuels is expected to lead to increases in US corn production, and subsurface drip irrigation (SDI) is one possible way to increase application efficiency and thereby reduce water use. Th...
