Automatización del riego en sustratos
Provedor de dados: 32
Autores: Ríos González, Pedro.
En México existe la necesidad de desarrollar tecnología de bajo costo para sistemas de producción agrícola por tal razón, se desarrolló un sistema de riego automatizado para sustratos, que controla la frecuencia de riego a partir de los requerimientos de la especie y naturaleza del sustrato. Se realizó la caracterización física de los sustratos (agrolita, fibra de coco, arena, peat-moss, tezontle y tepojal) y se diseñó un sustrato (mezcla) con el método de Zamora (2005). Se seleccionó el sensor de humedad  ECHO EC5  por  su baja respuesta a la conductividad eléctrica y se obtuvo la función de ajuste del contenido de humedad y la señal del sensor. El sistema de riego se integró por: un sistema electrónico de adquisición de datos y control (microcontrolador...

Development of capacitive sensor for measuring soil water content
Provedor de dados: 70
Autores: Segundo,Alan K. Rêgo; Martins,José H.; Monteiro,Paulo M. de B.; Oliveira,Rrubens A. de; Oliveira Filho,Delly.
The irrigation management based on the monitoring of the soil water content allows for the minimization of the amount of water applied, making its use more efficient. Taking into account these aspects, in this work, a sensor for measuring the soil water content was developed to allow real time automation of irrigation systems. This way, problems affecting crop yielding such as irregularities in the time to turn on or turn off the pump, and excess or deficit of water can be solved. To develop the sensors were used stainless steel rods, resin, and insulating varnish. The sensors measuring circuit was based on a microcontroller, which gives its output signal in the digital format. The sensors were calibrated using soil of the type “Quartzarenic Neosoil”. A...

Application technology for the entomopathogenic nematodes Heterorhabditis indica and Steinernema sp. (Rhabditida: Heterorhabditidae and Steinernematidae) to control Spodoptera frugiperda (Smith) (Lepidoptera: Noctuidae) in corn
Provedor de dados: 82
Autores: Garcia,Luiz C.; Raetano,Carlos G.; Leite,Luis G.
The effects of different application technologies were evaluated on the concentration, viability, and efficiency of infective juveniles of the nematodes Heterorhabditis indica Poinar, Karunakar &amp;amp; David and Steinernema sp. (IBCB-n6) to control Spodoptera frugiperda Smith on corn plants. Two hundred and eighty infective juveniles of Steinernema sp. were required to kill 100% third-instar fall armyworms in petri dishes, as compared to 400 infective juveniles of the H. indica nematode to obtain 75% fall armyworm control. It is possible to spray entomopathogenic nematodes without significant loss in their concentration and viability, with equipment that produces electrical charges to the spraying mix, and with those using hydraulic and rotary nozzle...

Fuzzy Water Irrigation System using Internet of Things
Provedor de dados: 111
Autores: Dhumale, Rakesh Dhumale.
Water is basic source of the farming with limited storage. Out of available land 64% is engaged by the farming and needs nearly 85 % of clean water of total water storage. Proper irrigation helps to improve quality of soil and the growth of crops. The farmer depending upon condition of soil and available water resource has to apply intelligence to get realistic decisions to reduce the wastage of water and ensure full utilization of the water. This gives challenging opportunity to pertain theory and idea of Artificial Intelligence (AI) in the process of water irrigation. In this paper, an intelligent approach for the water irrigation of crop is proposed. Smart Fuzzy Water Irrigation System (FWIS) using Internet of Things (IoT) includes two types of nodes...

Impacts of fertigation via surface and subsurface drip irrigation on growth rate, yield and flower quality of Zinnia elegans
Provedor de dados: 53

ABSTRACT Drip irrigation combined with split application of fertilizer nitrogen (N) dissolved in the irrigation water (i.e. drip fertigation) is commonly considered best management practice for water and nutrient efficiency. This research was conducted to study the influence of drip fertigation in combination with or without N fertilizers on vegetative growth, flowering quality, nutrients concentration in plants and soil fertility after the harvest of zinnia ( Zinnia elegans). A field experiment was conducted using a randomized complete block split plot design with two systems of drip irrigation (surface and subsurface drip irrigation) and 4 nitrogen rates (0, 30, 60, and 120 kg∙ha–1) as the main and split plots, respectively. The results revealed that...
