Evaluation of the agronomical performance of five new tomato varieties (Solanum lycopersicum L.) against two pest and disease control treatments in the province of Loja
Tomato is one of the most consumed vegetables, with abundant pests and diseases problems limiting its production. This research had two objectives: in the first one, the morphological characteristics of five different tomato populations, were described; in the second, the yield response of candidate-to-be varieties genotypes was evaluated when submitted to chemical or biological control of pest and diseases that commonly attack the crop. The populations showed distinctive morphological characteristics, fruit firmness, size, and shape. The experimental test results indicated significant differences among varieties and in the interaction of variety x method of control. The control variety showed the lowest yield (28,630 kg·ha-1) when compared to the candidate varieties, especially Variety 2 (66,090 kg·ha-1). Variety 2 (cherry-size-fruit) and Variety 3 (large-size-fruit) should be taken into consideration for large-scale cultivation due to their high yield. Varieties 2 and 3 reacted adequately to both kind of pesticides, with an advantage in yield under chemical control. Nonetheless, the use of chemical products was minimal (3-4 applications were enough), as compared to the high number of applications that are currently used under the traditional tomato cultivation in Ecuador.

期刊介绍:
Bioagro es una revista científica del Decanato de Agronomía de la Universidad Centroccidental “Lisandro Alvarado” (UCLA). Su periodicidad es cuatrimestral y se publica en los meses de enero, mayo y septiembre. Cada trabajo es revisado por al menos dos especialistas en el área, externos a la revista, de cuya opinión depende la aceptación definitiva. Se utiliza sistema de arbitraje doble ciego.
La revista va dirigida, fundamental pero no exclusivamente, a profesionales y técnicos del área agrícola. Su objetivo es publicar trabajos científicos originales e inéditos en ciencias agrícolas que enfoquen aspectos de agronomía, botánica y propagación de plantas, entomología y zoología, suelos, fitopatología y protección vegetal, ingeniería agrícola, genética y mejoramiento de plantas, ecología, procesamiento de productos agrícolas, biotecnología y sociales. También pueden ser publicados artículos cortos en los que se presenten descubrimientos científicos, desarrollos tecnológicos y resultados de diagnósticos integrales, en la modalidad de Notas Técnicas.
En Venezuela, se encuentra en las bibliotecas de todas las universidades e institutos de educación superior que ofrecen carreras agronómicas, así como de los entes oficiales de investigación agropecuaria. En el exterior, la revista llega a universidades y/o institutos de investigación agrícolas de todos los países de América Latina así como Estados Unidos, Canadá y España.
