Microbial infection plays an important role in the development of pulp necrosis and formation of periapical lesions. In vitro and in vivo research in this field, traditionally microbiological culture methods using paper point sampling and quantitative culture, faces difficulties in completely removing bacteria from the root canal system and analyzing sequential procedures. This study employed g...

Objective: Many agronomic practices may need to be adjusted to maximize yield and quality of sugar beet. Thus agronomic package must be always modified. This sutdy was laid out for evaluation of changes in carbohydrates and sugar yield in sugar beet (Beta vulgaris L.) under different biofertilizers and irrigation closed time at Dorud region of Iran, during 2013. Methods: The experiment...

This project proposed an embedded system for automatic control of irrigation. This project has wireless sensor network for real-time sensing and control of an irrigation system. This system provides uniform and required level of water for the agricultural farm and it avoids water wastage. These paper have real time sensing and control of an irrigation system. When the condition of waterin the a...

PURPOSE Denitrification is an important biochemical process in global nitrogen cycle, with a potent greenhouse gas product N(2)O. Wastewater irrigation can result in the changes of soil properties and microbial communities of agricultural soils. The purpose of this study was to examine how the soil denitrification genes responded to different irrigation regimes. MATERIALS AND METHODS Soil sam...

Objective: A field experiment was conducted at Dorud region, Iran, during 2013. The aim of this research  was study on effect of different biofertilizers and irrigation closed time on some agronomic characteristics of sugar beet (Beta vulgaris L.). Methods: The experimental design was factorial based on RCBD with three replications. Treatments were three irrigation closed time [Oct-6 (...

As more subsurface drip irrigation (SDI) systems are being installed throughout the plains of Texas for cotton production, irrigators are concerned about the high cost of installation and the potential benefits of alternative designs. A field study was conducted at the Texas AgriLife Research facilities at Halfway, Texas, to document the agronomic impacts of distribution uniformities on cotton ...

Crop production is a process of multiple inputs (water and nutrients, etc.), and the relationships between the inputs and crop yield are very complex. This study used a model for data envelopment analysis (DEA) to evaluate the efficiency of irrigation-fertilization schemes for winter wheat in North China. The field experiments were conducted at the Xiaohe Irrigation Experiment Station in Centra...

Water is a limited resource and the dramatically increasing world population requires a significant increase in food production. For improving both crop yield and water use efficiency, the usual optimization strategy in irrigation at the field level considers scheduling parameters, i.e. when and how much to irrigate, as well as control parameters, i.e. the intensity and the irrigation time, for...
