Sistema De Ensilaje Como Modelo De Producción En El Municipio De San José Departamento Del Guaviare, Nelby Nerieth Urrego Ramos Jan 2020

Sistema De Ensilaje Como Modelo De Producción En El Municipio De San José Departamento Del Guaviare, Nelby Nerieth Urrego Ramos

Ingeniería Agronómica

El presente trabajo se basó en el desarrollo del proyecto productivo a través de un sistema de ensilaje como modelo de producción en el municipio de San José departamento del Guaviare, en el que se describe la metodología y resultados obtenidos del desarrollo de cada uno de los componentes trabajados en el proyecto. En cuanto al componente de ingeniería agronómica se implementó una hectárea de maíz (Zea mays) del híbrido ATL 200 en el municipio de San José, con fines de ensilaje para consumo animal principalmente ganado bovino. De tal forma, que el componente de emprendimiento se basó en la …


El Fríjol (Vigna Unguiculata Y Phaseolus Vulgaris) Como Alternativa Para La Diversificación Agrícola En Yopal, Casanare, Duber Alejandro Pinto Ramírez Jan 2020

El Fríjol (Vigna Unguiculata Y Phaseolus Vulgaris) Como Alternativa Para La Diversificación Agrícola En Yopal, Casanare, Duber Alejandro Pinto Ramírez

Ingeniería Agronómica

El proyecto implementó una parcela demostrativa de 1.200 m², que incluyó manejo agronómico (plagas, enfermedades, arvenses, fertilización), la transformación de 2.270 kg del material vegetal en silo, y la comercialización del mismo con precio de referencia de 350 $ / kg, como alternativa de agronegocio a una Unidad Agrícola Familiar (UAF). Por otra parte, el objetivo del componente investigativo fue evaluar el efecto de tres densidades de siembra del fríjol rojo cuarentano (Phaseolus vulgaris) en la producción de grano, a través de la medición de parámetros de rendimiento; número de vainas por planta, número semillas por vaina, masa de 100 …

Local Binary Pattern Based Algorithms For The Discrimination And Detection Of Crops And Weeds With Similar Morphologies, Vi Nguyen Thanh Le Jan 2020

Local Binary Pattern Based Algorithms For The Discrimination And Detection Of Crops And Weeds With Similar Morphologies, Vi Nguyen Thanh Le

Theses: Doctorates and Masters

In cultivated agricultural fields, weeds are unwanted species that compete with the crop plants for nutrients, water, sunlight and soil, thus constraining their growth. Applying new real-time weed detection and spraying technologies to agriculture would enhance current farming practices, leading to higher crop yields and lower production costs. Various weed detection methods have been developed for Site-Specific Weed Management (SSWM) aimed at maximising the crop yield through efficient control of weeds. Blanket application of herbicide chemicals is currently the most popular weed eradication practice in weed management and weed invasion. However, the excessive use of herbicides has a detrimental impact …


Evaluating The Impact Of Grafting On Local Tomato Production In Nebraska, Raihanah Hassim, Samuel E. Wortman, Ashley A. Thompson, Stacy A. Adams Jan 2020

Evaluating The Impact Of Grafting On Local Tomato Production In Nebraska, Raihanah Hassim, Samuel E. Wortman, Ashley A. Thompson, Stacy A. Adams

Department of Agronomy and Horticulture: Dissertations, Theses, and Student Research

Grafting has been successfully used in vegetable production for tomatoes, peppers, eggplants, cucumbers, and watermelon. Besides its usefulness for managing soil-borne diseases, grafting can improve nutrient uptake and yield. However, few studies have assessed the effects of grafting and soil fertility management on yield of open field-grown tomatoes in the Midwest. Therefore, the objective of this two-year research was to better document the effects of grafting heirloom and hybrid tomato cultivar onto hybrid tomato rootstocks on tomato yield and quality. The field experiments were located at the University of Nebraska Lincoln - East Campus in Lincoln, West Central Research and …


Comparing Water Quality For Aquaponics Systems With Different Solids Removal Methods And Biofilter Media, And Effluent Output To Grow Beds, John W. Cutt, Heather M. Joesting, Brigette A. Brinton Jan 2020

Comparing Water Quality For Aquaponics Systems With Different Solids Removal Methods And Biofilter Media, And Effluent Output To Grow Beds, John W. Cutt, Heather M. Joesting, Brigette A. Brinton

Honors College Theses

Aquaponics is a closed-loop, sustainable method of food production that combines fish and plant production. This method of agriculture has the potential to bring fresh, local food to food-insecure areas, but challenges remain due to high operating costs. In order to develop a strong aquaponics industry, the creation of the most efficient system designs will be critical in optimizing production. This study’s purpose was to compare water quality between two aquaponics system designs that differ in filtration and solid removal methods. System 1 used a sock filter for solid removal and Kaldnes media for biofiltration while System 2 used a …
