For agricultural development, water is the most important thing, so today farmers are looking for crops that have some degree of resistance to drought and high economic value such as pomegranate, however, there is poor literature on its production. The Crop Coefficient (Kc) helps us determine the water requirement during plant development, which is critical for reducing production costs and saving water. The objective of this study was to know the Kc during the phenological development of the pomegranate, in an orchard located in the municipality of Gómez Palacio, Durango, Mexico, using 8 Landsat satellite images and geographic information systems. The estimation of Kc based on the Normalized Difference Vegetation Index (NDVI), was performed as proposed by Calera (2016). The KC values obtained range from 0.33 to 0.65. Its evolution with satellite images is consistent according to the development stages of the crop. The relationship between the NDVI and KC may be a promising tool for farmers to estimate water use of pomegranate trees on a regional scale based on satellite imagery.

Goals: Calculate the amount of Zinc Sulfate reagent that maximizes the lead benefit in the process of benefiting a plant in the southern region of the state of Chihuahua. Methodology: Tests were carried out with different amounts of zinc sulfate, on which the variance was calculated and the average benefit value of Lead and Zinc was determined. Then, the equations were obtained that describe the behavior of the benefit of the minerals and the maximum or minimum values with respect to the law were calculated. The optimized sulfate value was calculated and control charts were generated as follow-up to the process. Contribution: By optimizing and standardizing the amount of Zinc sulfate as a reagent in the benefit in a process where it was performed empirically, not only does it have greater control over the results of the law, but also the costs are optimized, considering that the Reagent use is an important input for the process.

In this article, a topology for energy conversion oriented to water pumping for irrigation in remote areas is proposed. A micro-hydraulic turbine working at fixed speed, in a "run-off-river" configuration, drives a centrifugal pump through a variable electric transmission (EVT). An EVT based on induction machines was selected, with the stator directly connected to a weak AC grid but the internal rotor fed by a variable frequency drive, allowing an adjustable pump speed. The grid supplies a base power for residential consumption, while the hydro turbine increases the available power for irrigation and thus augmenting productivity of the land uphill and beyond the vicinity of the watercourse. The grid also provides an assistance function, absorbing/delivering a reduced amount of power in case the hydraulic resource is excessive/insufficient for the requested water pumping. As the turbine delivery is constant, the water pumping requirement establishes the power exchanged between turbine, AC grid and pump. For this reason, an analysis to quantify the power flow in the system components for different pump speeds has been carried out. The system modeling is described and computer simulations, using a specific pump speed profile, are presented to validate the performed theoretical analysis.
