In Colombia, only purple type garlic is grown.However, there is a gap in access, government regulations and knowledge of the cultivars planted, which limits its optimal commercialization. The objective of this study was to evaluate the financial behavior of Nacional and Peruvian cultivars in the region of Cundinamarca and Boyaca highland.Sowing was carried out from 24 to the 29 of February of 2012, with a density of 210,000 plants/ha.Before of bulbs grew, 85 to 90 days after sowing (DAS), the National cultivar registered a lower dry weight of the aerial part (49 %) and bulb formation (57 %), number of leaves (10 %) and plant height (11 %) versus the Peruvian cultivar; nonetheless,after the 117 DAS there was no difference. The growth and phenology of both cultivations were quite similar. Approximately one month before harvest (130 DAS) the cost/ha was es imated to be 17.3 % higher in the Peruvian cultivar, mainly due to the larger amount of seed used (95.6 %). The local producer is very vulnerable to the price of the propagation material fixed by a few marketers, and even in the final product sale.","PeriodicalId":41142,"journal":{"name":"Revista Corpoica-Ciencia y Tecnologia Agropecuaria","volume":"17 1","pages":"43-53"},"PeriodicalIF":0.2,"publicationDate":"2016-05-04","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"68409126","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}

It is important to know different aspects of national honeys in order to verify the compliance with the existing Colombian requirements and International regulations, but also to increase its exploitation considering its quality and distinctive features. Physicochemical parameters are basic factors that determine the final quality of honey. The objective of this research was to assess commercial eucalyptus honeys developed with Apis mellifera in the region of Villanueva (Colombia). Water activity (0.54), pH (5.02), free acidity (14.58 meq kg-1), moisture (16.45 %),color (91.65 mm PFund),electrical conductivity (81.3 mS cm-1), minerals (ash, 0.81 %), reducing sugars (69.95 %), sucrose (1.48 %), hydroxymethylfurfural (HMF, 67.29 mg kg-1), diastase activity (3.21 °Gothe),phenolic content (76.57 mg Quercetin/100 g), flavonoids (5.96 mg Gallic acid/100 g) and proline (180.68 mg kg-1) were determined in 24 honey samples following standard and usual procedures. The samples analyzed meet both national and international regulations for free acidity, moisture and HMF. No adulteration treatments were evidenced from proline content. However, the low diastase activity suggests that the honey went through some kind of overheating, probably during its storage under the high temperatures typical in the area of production. Usual estimations of phenolic and flavonoids content were detected. In conclusion,the tested samples fulfill some of the requirements for their commercialization. Hence, it would be convenient to develop a better contrl of the honey production process in the Southwest Casanare.","PeriodicalId":41142,"journal":{"name":"Revista Corpoica-Ciencia y Tecnologia Agropecuaria","volume":"17 1","pages":"73-80"},"PeriodicalIF":0.2,"publicationDate":"2016-05-04","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"68409259","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}

However, pear itself does not provide the amount of protein required for cattle feeding, so alternatives to improve its nutritional quality have been studied. On these grounds, the objective of this study was to evaluate the parameters of solid state fermentation, and compositional energy value of a protein food based on pears (Pyrus communis) with apparent physical damage. A completely random design was used to evaluate three treatments; these correspond to percentages of inclusion of calcium carbonate (0.25, 0.50, 0.75) formulation based on already established (40% pear, 25% rice flour, 25% wheat bran and 10% urea), the parameters evaluated were: pH, ashes (CZ), crude protein (CP) and crude fiber (CF), and they were recorded at 0, 24, 48 and 72 hours. As a result, it was found that the pH dropped gradually for each treatment and at each sampling period; however, there were no significant differences. The lower value at the end of the process is recorded T2 (0.25) with 4.66, followed by T3 (0.50) with 4.50, the ash reached values of up to 6% with T3, and T2 (0.50) reached the highest percentages in fiber and crude protein. Finally, ecreasing the fermentation variables ensures a food with no presence of undesirable microorganisms and stable over time.","PeriodicalId":41142,"journal":{"name":"Revista Corpoica-Ciencia y Tecnologia Agropecuaria","volume":"17 1","pages":"7-16"},"PeriodicalIF":0.2,"publicationDate":"2016-05-04","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"68409547","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}

The objective of this research was to develop a yogurt with goat’s and cow’s semi-skimmed milk, using oats, mango y stevia evaluating their effect on the physical, chemical, structural,nutritional and sensorial characteristics during storage,while drawing the added value provided by goat’s and cow’s semi-skimmed milk, oats, mango and stevia as a sweetener and its use in industry. The yogurt was made taking into consideration three mixtures of goat and cow milk 90 %-10 %, 70 %-30 %-50 %-50 % respectively, sensory analysis determined that the best mix corresponded to 70 %-30 %. Eight formulations 70 %-30 % of yogurt were prepared by combining oats, mango and stevia at different concentrations before and during incubation. The experiment was 15 days long and the pH, acidity and syneresis were evaluated. The best formulation was selected and compared to a mixture of goat`s and cow`s semi-skimmed milk with sucrose. The physicochemical, microbiological,proximal, sensory and structural characteristics were determined for both treatments during 30 days.

In Colombia, information about its causal agent and the external factors that foster its development is scarse,which lead us to carry on a preliminary research. In three avocado farms of Fresno municipality, the severity of the spot in Lorena cultivar fruits was evaluated by using five types of barriers and a control, from the inflorescence phase to the developed fruit. The symptoms of the “avocado spot” in Lorena’ cultivar were characterized. Samples from different plant organs were sent to four diagnostic laboratories. Besides, in ten farms of Fresno municipality,the severity of the spot was measured on Lorena, Hass and Choquette cultivars by carrying out bi-weekly samplings.Simultaneously, in eleven farms in Fresno, the culture labors,pesticides, production costs and incomes were recorded.The treatment that was significantly different from the control was the fungicide application. The phytopathological diagnosis identified two pathogens, Glomerella sp. (Anamorphic:Colletotrichum sp.) and Cercospora sp. related to the spot symptoms. The Lorena cultivar was the most affected by “the spot”, it caused an increase of 3.65 % of the production costs to growers and the crop incomes decreased 21.65 % due to fruits with “spot” symptoms. An environmental impact was perceived as a result of the grower lack of awareness about the problem.","PeriodicalId":41142,"journal":{"name":"Revista Corpoica-Ciencia y Tecnologia Agropecuaria","volume":"16 1","pages":"265-278"},"PeriodicalIF":0.2,"publicationDate":"2016-01-21","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"68408754","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}

To achieve this, a pioneering research in Colombia was conducted to determine the adaptation of cotton in the acid conditions of the high plains improved sheets. An Agronomic evaluation test was developed using five elite genotypes of cotton in a design of a randomized complete block at four locations in soils with base saturation above 80 %. The results identified a genotype (LC-156), which presented an adaptation to the high plains, associated with an average yield of 2.2 t/ha of cottonseed, 1.5 t/ha of cotton fiber type medium-long, a percentage of fiber extraction above 36.0 %. The comparative advantage of this region for sustainable cotton production is given by the yield of cotton fiber —which ishigher than the national average—, to the 33.2 % reduction in production costs, the quality of long/medium-fiber destined for export and the absence of the pest insect of greatest economic impact in Colombia: the weevil (Anthonomus grandis Boheman).","PeriodicalId":41142,"journal":{"name":"Revista Corpoica-Ciencia y Tecnologia Agropecuaria","volume":"16 1","pages":"251-263"},"PeriodicalIF":0.2,"publicationDate":"2016-01-21","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"68408620","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}
