Hourly evapotranspiration (ET) crop coefficients (Kc) are needed to optimize the effectiveness and efficiency of high-frequency microand sprinkler irrigation practices involving the application of water multiple times a day. However, not much is known about the daily and seasonal patterns and magnitudes in hourly Kc values for soybean. In addition, locally developed Kc values are necessary for ...

Corn was an important crop for people who lived in the area that became Illinois before the Europeans first set foot here; it was the staple food crop of the people who lived in the Cahokia area some 1,000 years ago. It was a crop of choice when Europeans settled and started to farm in Illinois, and acreage in the state first reached 10 million acres in 1895. Acreage over the past 100 years has...

abstract introduction: septicemia is an important and common cause of neonatal mortality and morbidity. several factors such as genetic, social, hygienic and nutritional factors are effective on the frequency of bacterial pathogens in neonatal septicemia, several studies have performed to determine common pathogens in the different parts of the world. objective: comparison of neonatal bacterial...

Evapotranspiration (ET) over an oilseed crop, Camelina sativa, was evaluated for an experimental plot in Maricopa, Arizona between December 2006 and April 2007. Camelina (cv. Robinson) was grown in a 1.3-ha field in a randomized design containing 32 plots replicated for four levels ofwater depletion: 40, 55, 65, and 75%. Six supplemental plots evaluatedwater stress with 85% soil water depletion...

FLOW-AID has the objective to develop and test an irrigation management system that can be used under deficit, when water availability and quality are limited. It intends to use innovative, but simple and affordable concepts usable for a variety of irrigation set-ups and constraints. Amongst others, it focuses on development of low-power wireless sensor networks for soil water monitoring. Six s...

Zhou, X. B. and Y. h. Chen, 2011. Yield response of winter wheat to row spacing under irrigated and rainfed conditions. Bulg. J. Agric. Sci., 17: 158-166 In China, wheat (Triticum aestivum L.) is cultivated across a wide range of climatic conditions. The average rainfall was recorded at 696.6 mm per year from 1971 to 2008 at Taian in northern China. Considerable variability in the row spacing (...

Development of best management practices (BMPs) such as conservation tillage and winter cover crop to mitigate runoff and reduce dissolved chemicals in irrigation runoff is an important objective for controlling surface water pollution attributable to agricultural activities. In this study, the effect of standard tillage (ST), STwith winter cover cropping (STCC), and no-till (NT) management pra...

to be eff ective vectors of apple pollen.” Pollination is an essential step in production of fruits and many vegetables. Th e most widely used insect for fruit pollination is the European honey bee, Apis mellifera. Honey bees are ideal pollinators in many crop systems: each colony produces thousands of foraging workers and colonies can be moved into orchards and fields during the flowering peri...
