“…FYM can increase crop production through a variety of ways: provision of additional nitrogen, provision of phosphorus, provision of potassium, etc. increased soil organic matter, and improved soil water holding capacity (McAndrews et al, (2006); Barbazan, 2004;Hati et al, (2006). This suggests that using the MBILI system with organic fertilizers could be a better option than opting for mineral fertilizers, because of the latter's high costs and environmental pollution.…”

Inherent low soil fertility in the highly weathered and degraded soils largely accounts for low and unsustainable crop yields in most African countries (Okalebo et al., 2006; Sanchez et. al., 1997). Productivity of maize and soybeans in Kenya, particularly in the western region is generally low. The high costs of inorganic fertilizers and the possibility of decreasing soil productivity in due to soil mining and environmental pollution demands a reassement of their use, vis-a-vis, other alternative technologies. The objective of this study was to assess the effect of selected cropping systems, N fertilizer and manure on maize and soy bean crop yields in western Kenya (Bungoma, Vihiga, and Teso). The experiment was a split plot design arranged and laid down in a randomized complete block design (RCBD) with three replications. Cropping systems (mono cropping, MBILI and conventional) were the main factor while fertility interventions (FYM and CAN) were the treatments. The cropping systems consisted of conventional (Maize and soy beans were planted as intercrop in 37.5 cm alternating rows), MBILI (Managing Beneficial Interactions in Legume Intercrops), maize and soybean monocrop. Five fertilizer treatments were used: calcium ammonium nitrate and farm yard manure, both applied at the rate of 30 kg N ha-1 and 75 kg N ha-1, respectively, and absolute control that had no added treatment. Field experiments were planted during two cropping seasons of short rains season (August to December 2011) and one long rains season (April to August 2012) Generally, maize yields were found to be significantly higher in both the mono cropping system (mean yield: 2.00 t/ha) and MBILI system (mean yield: 1.77 t/ha) compared to conventional farming (mean yield: 1.27 t/ha). Soybean yields were found, overall, to be significantly higher in the mono cropping system (mean: 1.00t/ha) compared to both MBILI (mean: 0.75 t ha-1) and conventional system (mean: 0.59 t ha-1). For both maize and soy bean grain, application of CAN75N and planting with FYM75N were found to significantly increase yields, compared to either top dressing with CAN30N or planting with FYM30N. CAN generally produced higher yields with monocrop system whereas MBILI system did better when FYM is used, suggesting that an optimal system could consist of MBILI with organic fertilizers. The mean Land Equivalent Ratio (LER) values were always greater than 1.0 for intercropping and I.0 for mono cropping system. Manure was found to produce similar yields as those in fertilizer applications. This study recommends MBILI system and organic manure as a beneficial way of growing maize and soy beans

“…Use of organic fertilizers, such as farmyard manure (FYM) could ameliorate some of these deleterious effects. Manure application has been found to provide nitrogen, phosphorus, potassium, etc., and increase soil organic matter and improve soil water holding capacity (Hati et al, 2006;Barbazan, 2004).…”

“…El módulo de identificación es el que se encarga del reconocimiento de los individuos registrados, mediante una aplicación de control de acceso. El proceso de identificación da inicio cuando el lector biométrico captura la característica del individuo a ser identificado y la convierte en un formato capaz de ser procesado por el sistema, para que a continuación el extractor de características reproduzca una representación compacta con el mismo formato del patrón (Barbazán Posse & Casalderrey Carballal, 2018). La representación resultante es enviada al comparador de características que contrasta a éste contra uno o varios patrones de prueba para establecer la identidad.…”

The main objective of the project is focused on the development and implementation of a system for the management and control of markings for the personnel of the Metropolitan University of Ecuador, which fundamentally seeks to reduce the evasion of attendance record markings of teaching, administrative and auxiliary, in front of the assistance control teams by sending early alerts remembering to record your entry or exit. Considering the data collected by biometric devices that are strategically located in dependencies of the institution. The project is carried out in a web environment supported by the free software approach and which is adjusted to the infrastructure that the institution has, and since this software can be implemented in a multiplatform environment, this system adapts to business software like the UMET counts. For the execution of this project, the RUP Unified Rational Process is used as a software methodology, because this methodology mitigates the risks in software implementation. Free programming languages such as PHP and SQL were used as a database language, using MariaDB as the manager of those databases.
