This article presents a description of the design, development, and implementation of web-based software and dedicated hardware which allows for the remote monitoring and control of a drip irrigation system. The hardware consists of in-field stations which are strategically distributed in the field and equipped with different sensors and communication devices; a weather station and drip irrigation system complete the setup. The web-based software makes it possible to remotely access and process the information gathered by all the stations and the irrigation controller. The proposed system was implemented in a young olive orchard, located in the province of San Juan, an arid region of Argentina. The system was installed and evaluated during the seasons 2014–2015 and 2015–2016. Four regulated irrigation strategies were proposed in the olive orchard to test its behavior. In this pilot experiment, the precision irrigation system was a useful tool for precisely managing the irrigation process, applying only the required amount of water (precise irrigation). Regulated deficit irrigation experiments, on the other hand, have demonstrated the sensitivity of olives to water restriction. The precision irrigation system made it possible to control soil moisture levels, avoiding water stress in the control treatment.

A field experiment was carried out in the field of the College of Agriculture / University of Wasit, located on longitude  45o   50o   33.5o   East and latitude 32o 29o 49.8o North, in Spring season of the agricultural season 2019, in order to estimate the water consumption of potato crop using SWRT technology and under the drip irrigation system. The experiment was designed according to Randomized Complete Block Design (RCBD) with three replications and four treatments that include of the SWRT treatment (the use of plastic films under the plant root area in an engineering style), and the treatment of vegetal fertilizer (using Petmos), organic fertilizer (sheep manure), and the control treatment . Potato tubers (Solanum tuberosum L.)  var. Burin was planted for spring season on 10/2/2019 at the soil depth of 5-10 cm. The highest reference water consumption for the potato crop during the season was calculated by Najeeb Kharufa, which was 663.03 mm. The highest actual water consumption for the potato crop during the season for the control treatment was 410.1 mm. The results showed increase in the values of the crop coefficient (Kc) in the stages of tubers formation and tubers filling stage as compared to the vegetative and ripening stages, ranged from 1.37-1.92 for the two stages of tubers formation and tubers filling. The SWRT treatment gave the highest water use efficiency during the season, was 3.46 kg m-3 .

Pyrenochaeta Terrestris

The producers areas of onion in Mexico, are affected by the existence and increment of pathogens organisms of the soil like the fungus Pyrenochaeta terrestris, This problem increased its presence and damages due to the consecutive establishment of this vegetable year with year on the same soils. The fungus is activated and this disease developed when the soil temperature is increased. The disease infection of the plants causes rot and death of roots and small bulbs whit no commercial value, and low yields. According that the objective of the present research was to evaluate three treatments for the control of this organism pathogen: The experiment was carried out on INIFAP-CIRNO Experimental Station on a severally infested soil whit this fungus. The sow date was on 6 Jan. 2002, in this trial we used “local” variety. The treatments evaluated were Trichoderma (30 L·ha-1), Humega 8% (180 L·ha-1), Isofert 25 (400 L·ha-1) and a control (without treatment). The products were applied using the drip irrigation system. The results indicate that the treatments with Trichoderma and Humega 8% presented the lower percent of disease roots with 33% and those of more incidence were the control and Isofert 25 with 46% and 47% of disease roots, respectively. The results show 13% efficiency with the use of Trichoderma with respect to control; however this treatment did not affect the bulb weight and yield, control treatment obtained the greatest bulb weight and yield with 212 g for bulb and 80.9 t·ha-1 against 196 g and 71.9 t·ha-1, respectively, of the Trichoderma, which was seemingly a secondary negative effect in decrement the yield.
