In past few years, automatic irrigation system has seen a rapid growth in terms of technology. At present cost-saving technology, labor-saving are the addressing key issues in irrigation. This paper gives a review of these systems based on existing technologies and also proposes an economical and generic automatic irrigation system based on wireless sensors with GSM-Bluetooth for irrigation sys...

This study aimed to evaluate the fruit yield and the distribution of ‘Tommy Atkins’ mango root system under different irrigation regimes in the semiarid region of Bahia. The experimental design was completely randomized with five treatments and three replicates: 1 Irrigation supplying 100% of ETc in phases I, II and III; 2 Regulated deficit irrigation (RDI) supplying 50% of ETc in phase I (begi...

For the modeling and simulation of large water recovery and irrigation systems, standard component models as found in simulation tool libraries are too complex. In this work, simple models are derived and applied for the modeling and simulation of a real system. In this system, water for irrigation will be collected by recovery wells around the wastewater treatment plant infiltration basins loc...

Changes in irrigation water-use efficiency are related closely to agricultural development. Clarifying the driving factors of irrigation water-use efficiency change at different agricultural development stages is beneficial for buffering the contradiction between the protection of water resources and massive agricultural water consumption. It also has theoretical and application value when it c...

Gary A. Clark Research Irrigation Engineer Quick Facts Subsurface drip irrigation (SDI) is a low-pressure irrigation system that uses polyethylene driplines that are permanently buried below the soil surface. Water drips to the surrounding soil through built-in emitters (specialized small openings). SDI places water directly into the root zone of the crop. It may improve yield due to high appli...

AIM To compare the efficacy of photon-induced photoacoustic streaming (PIPS) technique with conventional, sonic and ultrasonic irrigation on the removal of apically placed dentinal debris from an artificial groove created in a root canal. METHODOLOGY Root canal preparation was performed up to size 40 on 48 extracted single-rooted teeth using ProTaper rotary instruments. The specimens were the...

Canal scheduling is an important activity that significantly influences production of crops compared to other aspects of agriculture. Irrigation canal scheduling is the activity of preparing an optimal schedule of outlets on supply canal as per need of user, subject to canal system constraints. In this paper, the problem of optimal operational scheduling of irrigation canal with provision to op...

Agriculture is one of the leading factor that has momentous impact on the GDP growth of the country. It provides the food and fibers for domestic and international industry. About 65 % of total earnings in Pakistan come from export of cotton, rice, and cotton based goods. The irrigation system of Pakistan is one of the best system in the world but still there is entire needs to improve the conv...

In the proposed Irrigation system IoT is implemented, in this system all the information that are received from the sensors and the various parameters are given to the arduinouno microcontroller as an analog input. A preset value of soil moisture sensor is fixed in microcontroller and also for fencing. When it goes beyond the particular threshold value water is automatically irrigated to the cr...

OBJECTIVES This study investigated the cleaning ability of ultrasonically activated irrigation (UAI) and a novel activation system with reciprocating motion (EC, EasyClean, Easy Equipamentos Odontológicos) when used with a relatively new chelating agent (QMix, Dentsply). In addition, the effect of QMix solution when used for a shorter (1 minute) and a longer application time (3 minutes) was inv...
