El objetivo del estudio fue definir las zonas agroclimaticas aptas para el cultivo de cebolla en el estado Carabobo, Venezuela. Se utilizaron datos diarios de precipitacion de 41 estaciones climaticas, para la estimacion de la evapotranspiracion, cartas edafologicas de la entidad y programas de computo para los balances hidricos del cultivo. Se compararon los requerimientos del cultivo en cuanto al suelo, clima, y “oferta” edafoclimatica del area, para cuantificar satisfactoriamente los requerimientos cubiertos y, en consecuencia, se determino el grado de aptitud potencial del area para el cultivo especifico. Se analizaron separadamente las relaciones suelo-clima-cultivo, y luego se integraron mediante un Sistema de Informacion Geografica para obtener un resultado unico. El estudio determino que 787 km2 de las tierras agricolas del estado son aptas para el cultivo de cebolla. En areas de valles, zonas bajas de montanas, colinas, y llanura lacustrina de la Depresion del Lago de Valencia, pueden obtenerse rendimientos superiores a 95%. El estudio de zonificacion pretende ser la base de un modelo de produccion agricola sustentable, que sirva como herramienta de trabajo, consulta y orientacion de cara a las iniciativas que tengan relacion con la actividad agricola. EnglishThe development agroclimatic zoning, in addition to allowing the specific location of the areas with the greatest vocationfor particular productive activities, also makes it possible to recognize the locationof the available infrastructure for thepromotion of the sovereignty and food security of the country. The objective of the study was to define agroclimaticzones suitable for growing onions in the state of Carabobo, Venezuela. To do this, daily rainfall data were used from 41weather stations, climatic data for the estimation of evapotranspiration, edaphological charts of the entity and computerprograms for crop water balances. The requirements of the crop in terms of soil and climate, and the edaphoclimatic\"supply\" of the area were compared to satisfactorily quantify the requirements covered and, consequently, the degree ofpotential aptitude of the area for the specific crop was determined. The soil-climate-crop relationships were analyzedseparately, and then integrated by means of a Geographical Information System to obtain a unique result. The studydetermined that 787 km2of the state's agricultural lands are suitable for growing onions. In these areas of valleys, lowareas of mountains, hills and the lacustrine plain of the Depression of the Lake of Valencia, yields higher than 95% canbe obtained. The zoning study aims to be the basis of a model of sustainable agricultural p","PeriodicalId":31531,"journal":{"name":"Journal of the Selva Andina Biosphere","volume":"57 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2018-11-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"78847441","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Este experimento se realizo con el objetivo de evaluar el comportamiento de nueve cultivares de cafe: Laurina IAC 870, Catuai vermelho IAC 144, Catuai vermelho IAC 99, Catuai amarelo IAC 86, Caturra amarelo Col. 88 IAC 476, Bourbon vermelho IAC 662, Caturra vermelho IAC 477, Obata IAC 1669-20 y Limani, injertados sobre Coffea canephora en presencia y ausencia de Meloidogyne spp. en fase de vivero. Los resultados mostraron que en altura y diametro de tallo destaco el injerto Obata IAC 1669-20/Robusta (inoculado), mientras que para numero de hojas, el injerto Caturra Vermelho IAC 477/Robusta (inoculado). Al medir la biomasa seca de la parte aerea y radicular, los injertos Laurina IAC 870/Robusta (no inoculado), Caturra Vermelho IAC 477/Robusta (inoculado) y Obata IAC 1669-20/Robusta (inoculado) tuvieron los valores mas altos.

In Peru, little work has been done to know the relationship between the barb and the graft holder, especially in thecase of coffee.

The results showed that the Obata IAC 1669-20/Robusta graft (inoculated) stood out in height and stem diameter, while for the number of leaves was theCaturraVermelho IAC 477/Robusta graft (inoculated). When measuring the dry biomass of the aerial and root part, the LaurinaIAC 870/Robusta (not inoculated), Caturra Vermelho IAC 477/Robusta (inoculated) and Obata IAC 1669-20/Robusta(inoculated) grafts had the highest values.
