One of the tools to counteract this biotic problem, which may be more profitable and respectful to the environment in the long term, is using biocontrollers such as Bacillus, Pseudomonas, Streptomyces (bacteria), and Trichoderma (fungus). It seems that each of these microorganisms has different mechanisms that allow them to inhibit and reduce the growth of P. capsici, negatively affecting the development of sporangia, germination and motility of zoospores, and expansion of germ tube. Although this direct biocontrol action on the phytopathogen correlates with the reduction of symptoms in Capsicum plants or other plant species, this would also involve the activation of defense responses in plants against P. capsici induced by microorganisms. The activity of several enzymes related to the isoflavonoid pathways and reactive oxygen species, as well as the expression of different genes that encode proteins related to pathogenesis and other proteins that can activate the jasmonic acid, salicylic acid, or ethylene signaling pathways. Despite the few existing works related to the biochemical and molecular interaction of Capsicum–P. capsici–biocontroller, in this review, we outlined and elucidated the possible effects and metabolic pathways related to this tripartite pathosystem.","PeriodicalId":21642,"journal":{"name":"Scientia Agropecuaria","volume":null,"pages":null},"PeriodicalIF":1.5,"publicationDate":"2022-09-21","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"41333629","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}

For many years, conventional agricultural management has generated losses of the topsoil and deterioration of soil properties, impacting in crop yields and deepening the degradation of this vulnerable ecosystem. The aim of this research was to determine the benefits of cover crops against erosion, soil health and quinoa yield. The trial was carried out in Huancarani and Cahualla towns, Mañazo district, Puno; with a randomized complete block design (RCBD) with four treatments: without cover and with clover (Medicago hispida G.), vetch (Vicia villosa) and mulch covers. We evaluated the physical, chemical, and biological characteristics of soil, the biomass of the cover crops and the quinoa yield. The results showed that the treatments with clover, mulch and vetch covers reduced soil erosion by 59.61%, 51.87% and 49.50%, respectively. Likewise, the use of clover and vetch covers increased organic carbon (29.71% and 31.16%), nitrogen (36.94% and 48.65%), and available phosphorus with clover cover (26.11%). Finally, clover cover associated with quinoa increased the yield of quinoa grain by 17% and reduced soil erosion significantly. These results show that cover crops have great potential for restoring soil health and improving yield.","PeriodicalId":21642,"journal":{"name":"Scientia Agropecuaria","volume":null,"pages":null},"PeriodicalIF":1.5,"publicationDate":"2022-09-21","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"48529569","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 study aims to understand the Peruvian conduct under the United Nations Framework Convention on Climate Change (UNFCCC) regime. Its influence in the Peruvian adaptation regulation and public institutions over the years and the interaction with the latest commitment to the UNFCCC related to climate change agriculture - water resources. The methodology used for the study was qualitative, delivered throughout a documentary analysis, and narrative design among scientific papers, UNFCCC documentation, and Peruvian regulation to weave the experience occurred and the sequences of the events to set up a general narrative. The results show that Peru has active participation in the UNFCCC, particularly under a neoliberalism approach. The convention pushed institutional and regulatory development of the Peruvian Government constantly. Also, after the Paris Agreement, one of the most important influences was the implementation of Law N° 30754 on climate change, which articulates all the regulations related to it, providing a national, more substantial legally-binding commitment. Finally, it is important for Peru to analyze the achievement of current adaptation actions and keep studying the impacts of climate change at a local level to develop a bottom-up approach for an effective policy formulation-implementation.","PeriodicalId":21642,"journal":{"name":"Scientia Agropecuaria","volume":null,"pages":null},"PeriodicalIF":1.5,"publicationDate":"2022-08-08","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"45595859","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}

Quinoa's nutritional profile stands out for its protein, carbohydrate, lipid and gluten-free content; it is rich in vitamins; and it is an excellent source of minerals, such as calcium, magnesium, iron and phosphorus. It is one of the few foods that have in its composition all the essential amino acids, standing out from other cereals such as rice or wheat. It is an excellent source of bioactive compounds, which have antioxidant, cytotoxic, antidiabetic and anti-inflammatory properties. With respect to quinoa leaves, several studies have indicated that they have higher protein content than grains, as well as inorganic nutrients such as calcium, phosphorus, iron and zinc. In addition, they can potentially serve as a rich source of phenolic compounds and carotenoids. Conventional heat treatments greatly or slightly affect the composition of the food, including bioactive compounds and antioxidant capacity. Germination provides the product with greater bioavailability and an increase in bioactive compounds. The purpose of this work was to document research on quinoa and its leaves, the effect of thermal treatments and germination on its bioactive compounds, in order to promote the creation and innovation of products based on its bioactive compounds, thus combating malnutrition in our population.","PeriodicalId":21642,"journal":{"name":"Scientia Agropecuaria","volume":null,"pages":null},"PeriodicalIF":1.5,"publicationDate":"2022-08-08","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"41525537","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}

In this work, a varietal survey was carried out by wine-growing areas, characterizing the local varieties of old vineyards, with 14 primary descriptors recommended by the OIV-2009 and genetically identifying a sample of 11 phenotypes with the use of 9-SSR molecular markers when compared in the VIVC international database record. Seven wine-growing areas of the valley and 39 varieties with local names were identified, initially forming 13 groups of different names, which when analyzed by means of the canonical discriminant analysis and of main components, high inter- and intra-group phenotypic variability is evidenced due to the influence of some characters. In the analysis of the berry color the blue-black coloration predominates. Four varieties registered in the VIVC were genetically identified, corresponding to ´Listan Prieto` (syn. Negra Criolla and Moscatel), ´Quebranta` (syn.Vinera), ´Muscat Hamburg` (syn.Italia Negra) and ´Jacquez` (syn. Borgoña Majeña) and 2 unregistered varieties “Cantarita” and “Aceituna de Cotahuasi”.
