Desempenho de morangueiro frente a diferentes espectros de radiação artificial complementar em cultivo sem solo

Among the various inputs used in strawberry cultivation, complementary artificial radiation has been a tool used in crops of high added-value. The this study was to evaluate the agronomic effects of complementation with photosynthetically active radiation in different spectra on strawberry crops, using fluorescent lamps in protected cultivation without soil. A completely randomized design with four replicates was used. The treatments encompassed the emission of radiation in different spectral ranges, using white, blue and red fluorescent lamps, and the combination of blue and red lamps. There was a control group without complementary radiation. Physiological, phenological and production aspects were evaluated. The use of combined blue and red lamps, and of white lamps, anticipated flowering and increased the mass of fruit produced over the crop cycle. Blue lamps induced the production of fruits with great mean mass. Red lamps had no effects on the increase in production nor on the anticipation of flowering.

EXPERIÊNCIAS DIDÁTICO-PEDAGÓGICAS EM AGROECOLOGIA NA REGIÃO NOROESTE DO RIO GRANDE DO SUL

Atraves da demanda e da organizacao de estudantes do curso de Agronomia da Universidade Federal da Fronteira Sul – UFFS campus Cerro Largo - RS, desenvolveu-se o grupo de estudos denominado Grupo de Agroecologia Noroeste Missoes (GANOM), com o intuito de abordar mais amplamente a epistemologia do pensamento agroecologico e sua insercao no ensino, pesquisa e extensao na universidade. O foco principal do grupo sao as abordagens agroecologicas nos sistemas de producao adotados pela agricultura familiar. O objetivo deste artigo e relatar as experiencias do GANOM, desde sua criacao no ano de 2013 ate o ano de 2016, com o intuito de divulgar experiencias e incentivar iniciativas semelhantes em outras instituicoes. As reunioes do grupo sao quinzenais e ampliam a capacidade analitica da formacao academica, bem como estimulam a formacao de um senso critico acerca dos temas abordados. Alem de uma abordagem teorica, os discentes do grupo colaboram na organizacao de eventos, participaram em monitorias, projetos de pesquisa e extensao que abordam a agroecologia como eixo estruturador da formacao profissional. O grupo consolidou diversas parcerias com organizacoes e movimentos sociais do campo e da cidade, sendo que diversos metodos adotados pelo GANOM tambem sao relatados por outros grupos de estudos.

Didactic and pedagogical experiences in agroecology in the Northwestern Region of Rio Grande do Sul Abstract: As a result of the demands and the commitment of the students of the School of Agronomy at Universidade Federal da Fronteira Sul – UFFS, at Cerro Largo - RS, the study group called “GANOMxa0 - Grupo de Agroecologia Noroeste Missoes” (Agroecology Group from Northwestern Missions) was createdxa0 to deeply address the epistemology of agroecological thought and their integration in teaching, research and extension practices at the university. The main focus of the group is the agroecological approaches related to the production systems adopted by family farming. Based on the aforementioned aspects, the objective of this paper is to report the experiences of GANOM since its creation in 2013 until the year 2016, in order to further disseminate the experiences and to encourage similar initiatives in other institutions. Group meetings were every other week and had the purpose of enhancing the analytical capabilities of their members, stimulating the development of critical sense on the topics studied. In addition to a theoretical approach, the students of the group collaborated in the organization of other activities, tutoring, research and extension projects that addressed agroecology as a structural axis of vocational training. The group consolidated several partnerships with organizations and social movements in the countryside and in the central city area. The different methods adopted by GANOM are also reported by other study groups. Keywords : University Extension, Agroecological Practices, Social Movements. Experiencias didacticas y pedagogicas en agroecologia en la Region Noroeste de Rio Grande do Sul Resumen: Como resultado de las demandas y el compromiso de los estudiantes de la Facultad de Agronomia de la Universidad Federal de Frontera Sur - UFFS, en Cerro Largo - RS, el grupo de estudio llamado GANOM - Grupo de Misiones Agroecologia del Noroeste (Grupo de Agroecologia del Noroeste misiones) fue creado para abordar profundamente la epistemologia del pensamiento agroecologico y su integracion en las practicas de ensenanza, investigacion y extension en la universidad. El objetivo principal del grupo es los enfoques agroecologicos relacionados con los sistemas de produccion adoptadas por la agricultura familiar. Sobre la base de los aspectos mencionados anteriormente, el objetivo de este trabajo es dar a conocer las experiencias de GANOM desde su creacion en 2013 hasta el ano 2016, con el fin de difundir aun mas las experiencias y para fomentar las iniciativas similares en otras instituciones. Eran reuniones de grupos cada dos semanas y tenia el proposito de mejorar las capacidades analiticas de sus miembros, estimular el desarrollo del sentido critico sobre los temas estudiados. Ademas de la aproximacion teorica, los alumnos del grupo colaboraron en la organizacion de otras actividades de la agroecologia, tutoria, investigacion y extension proyectos Que Dirigido al eje estructural de la formacion profesional. El grupo consolido Varias asociaciones con organizaciones y movimientos sociales en el campo y en la zona central de la ciudad. Los diferentes metodos adoptados por el GANOM tambien son reportados por otros grupos de estudio. Palabras-clave : Extension Universitaria, Practicas Agroecologicas, Movimientos Sociales.
