However, it is important to note that developed innovations to improve maize, Zea mays L. (Poaceae) productivity are not entirely implemented by small producers. In order to assess the social, economic, and environ-mental attributes of small-sacale maize farmers in the Colombian Caribbean region, a structured survey was conducted on 227 farmers in the depart-ments of Atlantico and Magdalena, which were selected through a stratified sampling method with proportional allocation. The resulting information was subjected to evaluation with Zero-truncated Poisson regression using the statistical software stata®. The results indicated that in the depart-ment of Atlantico, age, education, diffusion index, land ownership, use of machinery and institutional support are statistically significant (p<0.10) and in the department of Magdalena, diffusion index, education, land ownership, associativity, institu-tional support, and water regime are statistically significant (p<0.10) regarding the use of agri-cultural practices. It is concluded that innovation results from a complex process influenced by internal (the innovator himself ) and external (cultural and institutional) factors.","PeriodicalId":41142,"journal":{"name":"Revista Corpoica-Ciencia y Tecnologia Agropecuaria","volume":"18 1","pages":"7-23"},"PeriodicalIF":0.2,"publicationDate":"2016-12-27","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"68410086","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}

Since these are highly toxic compounds, their excessive use has caused great deterioration of arable soils, as well as serious damage to ecosystems and human health. Bioremediation is used as an alternative way to transform pesticides into simple, less polluting compounds, using the metabolic potential of microorganisms. Therefore, the objective of this study was to summarize the fungi and bacteria involved in bioremediation of the main organophos-phorus pesticides used in agricultural soils through a systematic review of the scientific literature, in order to provide useful information for conducting further studies. Scientific information was obtained through the use of databases such as ScienceDirect and Springer Link and unindexed information was also gathered from Google Scholar, as a result of this study, it was found that the most studied organophosphate pesticide is chlorpyrifos (Toxicity category III) and microorganisms most commonly used in the bioremediation of organophosphate pesticides belongs to the genera Serratia, Bacillus and Pseudomonas. It is concluded that the success of bioremediation is influenced by the competitive ability of microorganisms, bioavailability and concentration of the organophosphate pesticide in the soil, pH, temperature and soil type, presence of nutritional supplements and high inoculum concentration.","PeriodicalId":41142,"journal":{"name":"Revista Corpoica-Ciencia y Tecnologia Agropecuaria","volume":"18 1","pages":"139-159"},"PeriodicalIF":0.2,"publicationDate":"2016-12-27","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://sci-hub-pdf.com/10.21930/RCTA.VOL18_NUM1_ART:564","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"68410742","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 main productionarea of panela in Colombia is known as “La Hoya del Rio Suarez” in the departments of Boyaca and Santander, with ca. 42,701 ha. Like other regions, there is a lack of a cane seed production system which ensures the phytosanitary quality and varietal purity of the seeds (stem cuttings) required by the subsector, thus resulting in the spread of insect pests and diseases that permanently limit the yield at harvest. The objective of this study was to revive the local seed cane production system at the hoya del rio Suarez region and for this purpose the process of obtaining germinated plants was established through a bud extraction technique under the Colombian National Seed Plan. The process of obtaining germinated plants by bud extraction was developed in cooperation with the Colombian Sugarcane Research Center (Cenicana), and became the baseline system for production of locally-selected sugarcane seeds for the region. As a result, 200.000 sugarcane seedlings were produced during 2014 and given to small and medium scale producers. Fifteen ha of commercial seedlings were established in order to renovate 10.000 ha with the varieties of sugarcane in the next four years.","PeriodicalId":41142,"journal":{"name":"Revista Corpoica-Ciencia y Tecnologia Agropecuaria","volume":"94 1","pages":"75-87"},"PeriodicalIF":0.2,"publicationDate":"2016-12-27","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"68410413","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}

At 180 days after anthesis (DAA) the fruits reached harvest maturity with intense orange color and an average mass of 209 g. The behavior of the fruit fresh mass and dry mass was sigmoidal simple. The total titratable acidity and total soluble solids increased with fruit development, while the respiratory rate decreased; firmness increased to 80 DAA and then decreased until harvest.

The samples were stored refrigerated at 15 °C during 15 days. Textural parameters were determined every two days, using a texture analyzer; viscoelastic properties were set by a test of relaxation and compression effort, adjusting the experimental data to the generalized Maxwell model. Also, to determine the model parameters described, an iterative process was performed by non-linear regression using least squares techniques damped by the Solver add-on in Excel 2013. The storage time influenced the texture profile of buns, and the increase of hardness from the eleventh day, which was attributed to moisture loss of the product during cooling. Chewiness was higher for longer storage time. Cohesiveness, adhesiveness and elasticity reported no significant differences with respect to storage time. Statistical differences were presented at initial and final relaxation speeds expressed in the Maxwell model. The experimental data were successfully fitted to the model (R2 > 0.95) which was statistically significant (p < 0.05) and the performance of the elastic module indicated that buns from the white Cariaco variety showed a characteristic behavior of a viscoelastic material, increasing its hardness during the days of storage.","PeriodicalId":41142,"journal":{"name":"Revista Corpoica-Ciencia y Tecnologia Agropecuaria","volume":"17 1","pages":"403-416"},"PeriodicalIF":0.2,"publicationDate":"2016-08-16","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"68410256","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 methodology included chemical and microbiological soil characterization, reaction evaluation to pests and diseases, multi-sited valuation by AMMI and selection of two varieties with better yield and nutritional content by ACP. In addition to these two prioritized genotypes, the Pearson correlation coefficient between seed micronutrient content for locations and years was determined. The biofortified genotypes surpassed the control group significantly in both yield and precocity. According to the ACP, the biofortified group differed from the control group in iron and zinc content in the seed, confirming its superior characteristics in nutritional quality, and resistance to pests and diseases. The AMMI showed that the genotype SMR43 reflected stability and predictability between environments and SMR39 had specific adaptation in the best location for grain production.
