This paper presents a bibliographic review about the factors that influence erosion in soils dedicated to pineapple cultivation, addressing papers reported in the international literature, subsequently positioning it in the context of the main producing municipalities presented in the Valle del Cauca region. The available research covers the last four decades, where losses are estimated between 35 and 178t ha-1year-1; the topography, the conditions of the access roads, some management practices, and edaphic properties related to erodibility stand out among the most critical factors. Finally, based on the climatic, edaphological, and topographic traits reported in the literature for the main pineapple producing region of Valle del Cauca, and considering current management practices, it is found that this area can present very high erosion values since the soils are susceptible, and the slopes are steep, some of them even higher than 70%. Therefore, it is suggested to carry out more research to determine the erodibility and erosivity of these areas to know the potential degradation index, which will function as a valuable tool for decision-making, the generation of management, and conservation recommendations of these soils.","PeriodicalId":211714,"journal":{"name":"Revista de Ciencias Agrícolas","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-02-08","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"126012695","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}

Due to their high degree of heterogeneity, it is difficult for producers and technicians to make decisions that guarantee the sustainability of these agroecosystems. Sustainability was evaluated and compared using multivariate statistical procedures and a minimum set of variables (CMV) was selected. With the integration of these values the environmental, economic, and social sub-index was formed, which allowed comparing the sustainability of production systems through the AMOEBA method (A general Method for Ecological and Biological Assessment). To assess sustainability, the General Sustainability Index (IGS) was developed, built from a Principal Component Analysis (PCA) of the standardized variables. The information obtained was integrated into an index that allowed qualifying the systems through the Sustainability Biogram. The study found that from the economic, social, and environmental point of view, the shaded coffee production systems with a rating of 0.649 and semi-shaded coffee with 0.601 are located in the category of good sustainability. The shade-free coffee and banana coffee systems, with values of 0.405 and 0.490 according to the assessment scale, are located as systems in a regular state of sustainability. The foregoing conclusion will allow analyzing the critical and very critical points, which helps with understanding and evaluating the potential to propose solutions that are feasible to bring the systems closer to good or optimal sustainability.","PeriodicalId":211714,"journal":{"name":"Revista de Ciencias Agrícolas","volume":"56 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2021-12-16","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"124574579","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}

Research has been carried out on onions to improve seed germination and to extend its use for sowing. The magnetic field is considered a simple, inexpensive, and non-invasive physical method to stimulate the germination process, compared to traditional chemical methods. In this sense the objective of this research were to evaluate the effects of static magnetic fields on Yellow Granex PRR hybrid onion (Allium cepa L.) seed germination, and early growth in the laboratory conditions. Seeds were exposed to 10 and 21mT, (mT=militesla), static magnetic fields induced by magnets for 0, 5, 3, 6, 12 and 24h; each treatment had four repetitions. The results showed that the low intensity stationary magnetic fields (10 and 21mT) did not cause significant differences in germination, dry weight, or fresh weight, but for the seedling length. It is necessary to increase the intensity of the magnetic fields and the exposure time to achieve important physiological changes that positively affect the germination and growth of onion seeds, and thus contribute to the improvement of their yield and productivity. The use of physical methods such as magnetism can stimulate different physiological processes in plants and thus contribute to the improvement of characteristics of agronomic interest.","PeriodicalId":211714,"journal":{"name":"Revista de Ciencias Agrícolas","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2021-12-16","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"114728109","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 impact of deforestation on carbon storage in total biomass and its CO2 emissions is analyzed in four land covers in the Santuario de Fauna y Flora Iguaque (SFFI), Boyacá, Colombia. A total of 32 temporal sampling plots (TSP) of 250m2 was established to measure trees with diameter at breast height (dbh) ³ 10 cm whereas 17 TSP of 36m2 were established to measure total and stipe height of all frailejones (Espeletia boyacensis Cuatrec, E. tunjana Cuatrec and E. cf. Incana). Above and belowground biomass was estimated with allometric models, whereas carbon was calculated using the 0.47 fraction. The sampling area was proportional to the area of each land cover: open heathlands and moorlands (OMH), dense heathlands and moorlands (DMH), broad-leaved forest with continuous canopy, not on mire (BFCC), natural grassland prevailingly without trees and shrubs (NSWT). BFCC and DMH showed higher carbon storage in biomass (55 and 27Mg C/ha, respectively). SFFI stored around 135.9Gg C, from which 25-38Gg CO2e could be emitted to the atmosphere in the 20 next years if the deforestation rates continue. BFCC and OMH are the covers with the highest potential of CO2 emissions to the atmosphere. Therefore, prioritizing the preservation of these ecosystems by Reducing Emissions from Deforestation and Degradation (REDD+) programs, is a key to counter the effects of climate change and ensure the supply of ecosystemic services that support local communities’ livelihoods.","PeriodicalId":211714,"journal":{"name":"Revista de Ciencias Agrícolas","volume":"29 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2021-12-16","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"117027848","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 present study aimed at evaluating the germination and initial growth of pepper seedlings produced from seeds under different soaking times in NaCl solutions. The experiment was carried out in a completely randomized design, in a 2 × 4 × 5 factorial scheme using two pepper species (Capsicum chinense Jacq. and Capsicum frutescens L.), four levels of electrical conductivity (EC) of solutions (1.5, 3.0, 4.5, and 6.0 dS m-1) and five times of seed soaking in the solutions (2, 4, 6, 8 and 10 h), with three replications. The traits evaluated were the number of germinated seedlings, percentage of germination, seedling height, and root length. The results showed that C. frutescens pepper was more tolerant to different times of soaking in saline solutions prepared with NaCl compared to C. chinense. Thus, the results suggest that depending on the pepper species, it is recommended to use seeds primed in saline solutions with salinity levels compatible with those under field conditions (in saline soils and/or irrigation with saline waters).","PeriodicalId":211714,"journal":{"name":"Revista de Ciencias Agrícolas","volume":"52 15","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2021-09-29","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"131722099","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 results were submitted to Pearson's correlation analysis, and they show that the flavonoid indices with the perigonium color intensity values express significant positive correlation. In addition, the antioxidant capacity equivalent to Trolox was significantly different between the perigonium color intensities, where the accession with black perigonium turns out to be the one that reached the highest value (5g eq.

Improving the management practices of cacao (Theobroma cacao L.) cultivation systems requires knowledge of their baseline and the determining factors affecting them. The main goal of this research was to characterize traditional cacao agroforestry systems of smallholder farmers in the Municipality of Tumaco, Nariño, Colombia. Using a semi-structured survey and a sample of 218 farmers, the socioeconomic characteristics of the cacao production system were analyzed. Multiple correspondence analysis (MCA) and principal component analysis (PCA) grouped and discriminated the cacao growers. The PCA formed five components representing 50.86% of the total variability, while the ACM grouped them into five factors explaining 29.82% of the variability. The cacao cultivation is a traditional activity of smallholder farmers with very low yields. The age of the farmers is over 50 years old, with despicable levels of education; there was no evidence of generational change. The study shows that the traditional cacao production system is not an attractive activity for young people or investors given its marginality and low economic projection. Timely strategies and subsequent early actions will be imperative to face the main environmental, socio-economic, and productive challenges, which will allow the cacao activity to be a source of well-being for cacao growers and the environment in the region.","PeriodicalId":211714,"journal":{"name":"Revista de Ciencias Agrícolas","volume":"6 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2021-09-29","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"115176127","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}
