Monitoring water stress in specialty crops to increase water use efficiency (WUE) is becoming more necessary when faced with the reality of depleting water resources. Leaf temperature (TL) of almond [prunus dulcis] and walnut [juglans regia] trees has been shown to...

A unique yield monitoring system has been successfully developed for studying the yield behavior of pistachio trees in two commercial orchards for the last seven years. Two systems are retrofitted onto two sets of pistachio catch-frame harvesters. Two orchards in Southern California have been har...

Almond and walnut are two major crops grown in the Central Valley of California. With virtually no rainfall in this area during summer, these crops need to be irrigated throughout the season. There is a demand for using irrigation scheduling tools for effective use of very limited supply o...

The goal of this research was to develop a mobile sensor suite to determine plant water status in almonds and walnuts. The sensor suite consisted of an infrared thermometer to measure leaf temperature and additional sensors to measure relevant ambient conditions such as light intensity, air...

Precision farming is the need of the hour for increasing the food production by providing innovative techniques to address spatial variability prevalent in agricultural fields.  Laser leveling is such a technique that can assist in reducing spatial variability in soil moisture content acr...

Agricultural land leveling is of high importance in modern and intensive agriculture, especially under drought prone conditions where water resources are limited. The technology of laser leveling is very much effective in tackling these issues. A study using the technique of laser leveling was...

  Rhodes grass is cultivated extensively in Saudi Arabia under center pivot sprinkler irrigation system. The research work was carried out to optimize irrigation water and fertilizer nitrogen levels for the crop. The objectives of the study were: (1) to delineate the field into ...
