Sin embargo, no se conoce en qué medida este enfoque ha sido adoptado por los productores. Este trabajo busca conocer cómo la agroecología se ha difundido en los sistemas productivos cercanos a la Universidad Nacional de La Plata. Se trabajó con una metodología cualitativa en base a entrevistas a informantes clave. Identificamos dos territorios, uno de carácter intensivo con predominio de la producción hortícola y otro extensivo basado en la producción ganadera. En las zonas donde predomina la producción hortícola se observó un crecimiento sostenido de la agroecología en los últimos cinco años, influenciado sobre todo por organizaciones de productores que la promueven e instituciones comprometidas con la temática. En estos casos, pese a la diferencia de visiones en las organizaciones de productores, encontramos procesos de conversión a la agroecología comunes en cuanto a motivaciones para el cambio de modelo, prácticas aplicadas, dificultades en el proceso y comercialización por canales diferenciados. Con respecto a los territorios de producción extensiva identificamos un desarrollo menor de la agroecología, circunscripto a unas pocas experiencias, con grandes diferencias entre ellas en cuanto a la pertenencia a organizaciones, objetivos y desarrollo de la propuesta agroecológica.","PeriodicalId":54470,"journal":{"name":"Revista De La Facultad De Agronomia De La Universidad Del Zulia","volume":null,"pages":null},"PeriodicalIF":0.2,"publicationDate":"2022-07-14","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"41973466","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"农林科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

For this, an electromechanical system was designed using infrared emitters that combines electromagnetic radiation with conventional convective heating. 75 coffee samples were collected at three (3) height levels. The samples underwent the traditional drying process and the electromechanical system, to later be evaluated by professional tasters under the SCAA (Specialty Coffee Association of America) scale. The samples dried with infrared at 12% humidity presented a cupping value of 82.93 for cup coffee with a smaller data dispersion than the traditional system that obtained 81.34, in addition the t-test of non-equivalent samples indicates that its value is significantly better (p<0.05).

A sampling for finite populations was carried out, and the sample size was 89 producers. Results showed that a minimum of 10,754.5 kg.ha-1 is required with a rural sale price no less than 5.6 $.kg-1 of jalapeño pepper (equivalent to $0.20), to maintain a profitable and sustainable commercial supply of the crop. Producers sold most of their jalapeño production to wholesalers (58.4%), despite results showed the fact, that direct markets are the most profitable marketing channel for farmers of the area. The gross marketing margin was 74.5%, which indicated that, by each peso paid for jalapeño consumers, 74 cents corresponded to the intermediation process, and 25 cents to the producer. The organization of producers is crucial to increase the quality of the product and for a greater presence in the marketing chain.","PeriodicalId":54470,"journal":{"name":"Revista De La Facultad De Agronomia De La Universidad Del Zulia","volume":null,"pages":null},"PeriodicalIF":0.2,"publicationDate":"2022-06-22","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"89343553","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"农林科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

For this, 1217 phenotypic and 439 genomic records of pure BON bovines were used. The Gompertz, Logistic, Von Bertalanffy and Brody models were evaluated. The individual growth curve parameters were estimated and the effect of SNPs of the IGF-1 and LEP/ob genes on the curve parameters was estimated through a linear model. Finally, the association of the curve parameters and the AFC was analyzed trough a linear model. The model that represented the best fit to the growth trajectory was Brody's. On average, the BON animals presented an adult weight (β0) of 479.9±7.4 kg and a growth rate expressing the daily weight gain as a proportion of the total weight (β2) of 0.002±0.00004. The SNPs rs110654613 (nucleotide change A/G) and rs110959643 (A/G), within the IGF-1 gene, showed a significant effect (p<0.05) on the parameters of the BON cattle growth curve. There were no associations of LEP/ob gene SNPs on the parameters of the BON cattle growth curve. AFC was significantly associated (p<0.05) with the parameters β0 and β2. It is concluded that the use of genomic information for the IGF-1 gene can lead to higher growth rates and earlier.","PeriodicalId":54470,"journal":{"name":"Revista De La Facultad De Agronomia De La Universidad Del Zulia","volume":null,"pages":null},"PeriodicalIF":0.2,"publicationDate":"2022-06-21","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"90814354","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"农林科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

For this, the PGPR traits of CSB were evaluated under laboratory conditions: the biological nitrogen fixation capacity, the reduction of acetylene, the synthesis of indole acetic acid (IAA) and the solubilization of phosphates. In a second experiment under plant nursery conditions, PGPR activity of strain CSB05 was evaluated in common bean plants. Under laboratory conditions, it was evidenced that all the evaluated strains produced IAA, solubilized phosphate in a liquid medium, presented atmospheric nitrogen fixation capacity, and only the CSB3 and CSB13 strains reduced acetylene. In the plant nursery experiment, PGPR activity of strain CSB05 was detected in common bean plants, reflected in increases in the height of these plants. These results show that CSB are promising in the PGPR activity, which is interesting to the design of biological products with agricultural and environmental applications, for the management of crops in disturbed soils of the Colombian dry Caribbean.","PeriodicalId":54470,"journal":{"name":"Revista De La Facultad De Agronomia De La Universidad Del Zulia","volume":null,"pages":null},"PeriodicalIF":0.2,"publicationDate":"2022-06-14","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"75856741","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"农林科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Nevertheless, the dynamics of these flows are unknown due to the absence of official statistics for small populations, which makes it difficult to analyze them in relation to poverty. Through an econometric model, the objective was to analyze the transition of income from agricultural production to sources in the service sector and remittances. It was taken as a study case, \"Eleodoro Dávila\" town from Filomeno Mata municipality, Veracruz, Mexico. Randomly, a questionnaire was applied to 33.33% of the population and an econometric model of expenditures on family well-being was built with data obtained. The dependent variable was expenditures on family well-being, while the independent variables were the diversity of sources of income. In addition, the elasticities of the independent variables were estimated from the econometric model. Primary and secondary activities, subsidies and household transfers were found to contribute to family well-being. In addition, it was found that a 1% increase in income from livestock production generates a 0.05% change in spending on family well-being, while agricultural production generates 0.16%. Trade, international and national remittances generate the greatest effects with 0.81%, 0.71% and 0.48% respectively. The situation that prevailed during 2019-2020 in the study community allows us to conclude that the agricultural sector has lost preponderance as the main source of income.","PeriodicalId":54470,"journal":{"name":"Revista De La Facultad De Agronomia De La Universidad Del Zulia","volume":null,"pages":null},"PeriodicalIF":0.2,"publicationDate":"2022-05-31","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"88405832","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"农林科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

For this, the carbon level was estimated at different soil depths (0-20, 20-40 and 40-60 cm) and in the herbaceous/shrub biomass in three systems (Brachiaria brizantha cv Marandú, Panicum maximum cv Colonial and Leucaena leucocephala consortium with colonial), with an interval of 30 days between the three measurement moments. The results generated from the biomass indicated that the system constituted by the colonial forage consortium with L. leucocephala, presented the highest level of carbon (3.73 t.ha-1), showing a significant difference in relation to the B. brizantha (2.12 t.ha-1; p<0.05). On the other hand, the initial period showed higher carbon concentration (4.55 t.ha-1; p<0.05). Likewise, a higher content was found at a depth of 0-20 cm (20.26 t.ha-1; p<0.05). These results were obtained in a winter process. In this regard, it is important to mention that forage shrubs in systems with pastures constitute a fundamental nutritional resource in winter, in this sense it is recommended to use improved and consortium pasture systems, to increase carbon storage, achieve stable and productive systems, in correspondence with its potentialities.","PeriodicalId":54470,"journal":{"name":"Revista De La Facultad De Agronomia De La Universidad Del Zulia","volume":null,"pages":null},"PeriodicalIF":0.2,"publicationDate":"2022-04-21","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"79795969","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"农林科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Additionally, processed products were selected for analytical determinations of moisture, NaCl content, and water activity. The results showed that 80% of the products are marketed in large supermarkets with 20% in local markets. It was also observed that 79% of the products are of national origin. The highest salt contents on a dry basis (~48%) were determined on smoked salmon and salted-smoked herring samples, while tilapia patties showed the lowest NaCl values on a dry basis ~6%. Within the Colombian market, products with a high degree of processing are imported and they contain higher salt contents.
