This state unveiled a technology gap,and issues such as the contribution of compositional differences in the varieties of cane on panela. To fill part of this technological gap, the objective of this work is to determine the effect of pressure evaporation and the varieties of cane on quality of honey and panela. To achieve this, the evaporation pressure and sugarcane varieties in one experimental design completely randomized with 4x3 factorial arrangement and four replications was implemented: varieties CC 85-46, RD 75-11 and PR 61-632, without flocculant, without coadjuvant and was evaporated with a heat flux of 27,778 kW/m2 and without antifoam. The results showed a similar behavior for the studied sugarcane varieties. So honeys and panelas in the pressurized system presented dark coloration, reddish tone, high turbidity, a glycoside coefficient between 60 % and 70 % and they did not solidified.Honeys and panelas in vacuum systems presented a reater turbidity, clear colorations, yellowish tones, and good solidification and coefficients glycosides under 12 %.","PeriodicalId":41142,"journal":{"name":"Revista Corpoica-Ciencia y Tecnologia Agropecuaria","volume":"16 1","pages":"153-165"},"PeriodicalIF":0.2,"publicationDate":"2016-01-21","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"68408911","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}

An analysis of variance and differences were statistically significant when the means were separated by Tukey test (p<0.05). The analysis found highly significant differences (p<0.01) in the concentration of soluble solids in different pastures, in all periods of the day evaluated, with the cultivar Mulato II that presented the highestvalues with 9.19 %, followed by Cynodon nlemfuensis and Panicum maximum with 8.27 % and 7.07 %, respectively. The soluble solids concentration varied during the day and between pastures. The time periods close to noon —10:00 a. m. and 1:00 p. m.— presented the highest concentrations of soluble solids in all pastures; this can be used as a tool for paddock rotation.","PeriodicalId":41142,"journal":{"name":"Revista Corpoica-Ciencia y Tecnologia Agropecuaria","volume":"16 1","pages":"181-188"},"PeriodicalIF":0.2,"publicationDate":"2016-01-21","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"68408944","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}

Variance analysis, Fisher test (p<0.05) and principal components analysis (PCA) were used fordata comparisons. For the height of cocoa plants, there was an average increase of 22.5 cm, while for stem diameter was 4.71 cm, with significant differences between the treatments. In general, an effect of the fertilizing scheme on the agronomic parameters of cocoa evaluated was found —especially for some important variables such as number of grains per pod and average weight of the grain—. There were similar parameters between the chemical and the organic treatments. This demonstrates that organic schemes of fertilizing could be an important alternative for improving cocoa production.","PeriodicalId":41142,"journal":{"name":"Revista Corpoica-Ciencia y Tecnologia Agropecuaria","volume":"16 1","pages":"307-314"},"PeriodicalIF":0.2,"publicationDate":"2016-01-21","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"68409483","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}

Economic statistics and estimates measurement techniques by the method of ordinary least squares (OLS) were used, especially for estimating the functions of supply and demand. For the analysis of competitiveness, the unit production cost of Colombia was compared against other countries producing cotton fiber. The results show, on the one hand, that the production of short fiber in Colombia is likely to increase and to dedicate more areas to such type of crops given the growing trend of demand from the industry, which exceeds right now the spinning rings or long-fiber; and on the other hand, the results show that under the current conditions the country is not producing cotton in a competitive way and therefore the component of imported cotton is growing over time","PeriodicalId":41142,"journal":{"name":"Revista Corpoica-Ciencia y Tecnologia Agropecuaria","volume":"16 1","pages":"189-215"},"PeriodicalIF":0.2,"publicationDate":"2016-01-21","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"68408989","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 rice cropping system has a large food, social and economical importance in the world; however, it is a net GHG-emitting productive system. The objective of this study was estimating the carbon footprint of the rice production in Campoalegre, Huila, Colombia. A total of 21 rice productive units, located at less than 15 km from the center of the municipality and with gravity irrigation, was selected. Through semi-structured interviews, all activities that emit GHGs, from land preparation to harvest grain, were investigated. It was consulted to producers and managers about the use of nitrogen fertilizers and fossil fuels and the yield of rice grain in each production unit. Factor of emission and warming-equivalence among GHG recommended by Intergovernmental Panel on Climate Change were employed. Carbon fixation rates estimated in Tolima were used to found alternative systems for mitigation of these emissions. It was found a total emission of 998.1 ± 365.3 kg CO2e/ha/cycle (163.3 ± 55.8 kg CO2e/t), having nitrogen fertilization being the greatest contribution (65%). Mitigation of this GHG emission would imply the establishment and management of 0.5 ha of cacao plantations without shade trees or coffee plantations with shade trees or 1.4 ha of monoculture coffee plantations.","PeriodicalId":41142,"journal":{"name":"Revista Corpoica-Ciencia y Tecnologia Agropecuaria","volume":"15 1","pages":"25-31"},"PeriodicalIF":0.2,"publicationDate":"2015-12-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"68407316","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}

This study aimed to evaluate the quality of compost made from different combinations of products of the milling process of sugar cane (Saccharum officinarum L.). Composting piles were established in the Ingenio Riopaila-Castilla, Valle del Cauca, Colombia, using a complete randomized block design with five treatments and four replications. 100% sugarcane sludge (T1), 75% sugarcane sludge and 25% bagasse (T2), 50% bagasse and 50% sugarcane sludge (T3), 25% sugarcane sludge and 75% bagasse (T4) and 100% bagasse (T5), all supplemented with 2 m3 of vinasse. The response variables: pH, electrical conductivity, moisture, ash, organic matter, moisture retention, the carbon-nitrogen ratio, the total oxidizable organic carbon, total nitrogen, phosphorus, calcium, magnesium, potassium, iron, copper, manganese and zinc, were evaluated at the time when the initial compost piles were prepared, and the 42, 51, 59, 73 and 90 days after beginning the process.
