However, few studies address the planting system of the species, especially its spatial arrangement. Thus, this study proposes to evaluate chia cultivation under different spatial arrangements, aiming at its agronomic performance. The experimental design was randomized in blocks in a 3×2 factorial scheme, with three inter-row spacings (0.30, 0.45, and 0.60 m), two plant densities per linear meter (7.5 and 15 plants m−1), and four replications. Plant height, stem diameter, leaf area index, dry matter, chlorophyll index, leaf nitrogen content, panicle size, harvest index, and yield were evaluated. The evaluated spatial arrangements did not influence plant height, stem diameter, dry matter, leaf nitrogen content, panicle size, and harvest index. However, the spatial arrangement with the narrowest spacing and the highest population density was more suitable for obtaining a higher leaf area index and yield, with values of 5.96 and 2,507.44 kg ha−1, respectively. Therefore, a higher leaf area index and chia seed yield are obtained with an inter-row of 0.30 m and a population density of 15 plants m−1, that is, 500 thousand plants ha−1.","PeriodicalId":55957,"journal":{"name":"Revista de Agricultura Neotropical","volume":" ","pages":""},"PeriodicalIF":0.3,"publicationDate":"2022-10-20","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"43066781","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 purpose of this study was to improve the techniques and methods of cultivating onions using new generation preparations against the background of N180P60K60 in a drip irrigation method. To achieve the objective of this study, field surveys, observations and measurements were carried out using generally accepted methods. The experimental data obtained from the studies were processed using analysis of variance in Excel, which is part of the Microsoft Office installation package. Field experience included both background application of mineral fertilizers, as well as integrated nutrition of plants with Aminofol Plus and Novosil bulb onion growth stimulants and its biological protection with drugs Gaitang, KE, Akzifor, KE and with Monarch, VDG preparations. According to the results of tests carried out in the 3rd soil-climatic zone, they positively influenced the growth processes and yield of the cultivated crop. The use of this scheme gave a significant increase in the number of commercial bulbs and the weight of commercial bulbs relative to the control version, which significantly affected the yield, which was 121.8 tons/ha (commercial yield). Based on the results of the obtained experimental data, the following was identified, the difference in yield is due to the effect of drugs that have a positive effect on the variety and hybrid of onions, which are under study.","PeriodicalId":55957,"journal":{"name":"Revista de Agricultura Neotropical","volume":"1 1","pages":""},"PeriodicalIF":0.3,"publicationDate":"2022-10-06","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"41593008","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}

Soil samples from the 0.0-0.05, 0.05-0.10, and 0.10-0.20 m layers were collected to assess soil density (Sd), TOC contents, with subsequent calculations of the stratification index (SI), carbon stock (StockC), and variation of the total organic carbon stock (∆StockC), in addition to the determination of daily emission and calculation of total C-CO2 accumulation. The NF area had the highest levels and stocks of TOC, reaching 16.42 g kg-1 and 20.90 Mg ha-1, respectively. On the other hand, the PP and PNHR areas had the lowest content and StockC. The areas of PP, DS, PNHR, and NF presented SI values of 1.08, 1.13, 1.32, and 1.61, respectively. The NF area showed higher peaks and a higher total accumulation of C-CO2, inferring the highest biological activity in this area. By multivariate analysis, none of the managed areas was close to the NF in quality. The worst results considering the evaluated attributes were observed in the areas of PP and PNHR due to the stage of degradation of these areas as a result of exploration and land use history.","PeriodicalId":55957,"journal":{"name":"Revista de Agricultura Neotropical","volume":" ","pages":""},"PeriodicalIF":0.3,"publicationDate":"2022-09-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"49362087","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}

A total of 23 samples from black pepper cultivars/clones were evaluated for impurities and foreign matter, empty grains, density, moisture and ether extract, as established by Brazilian legislation. Additionally, the contents of total ash, protein, crude fiber and piperine were determined. Among the samples, one was outside the standard for density. The moisture contents were below the maximum limit required by the legislation, demonstrating that the drying and storage of the grains were adequate. Regarding the ether extract, 52% of the samples did not meet the commercialization standards. Concerning piperine, the Equador and Panny clones had levels greater than 5%. It was found that the nutritional composition of black pepper is influenced by the technological level of the production system.

The treatments consisted of three different soil base saturation (36, 60, and 80%), combined with foliar application of thiamine (with and without) at a concentration of 100 mg L-1. It was found that thiamine mitigates the effects of low base saturation on the physiological traits of bell pepper plants. The increments related to the water use efficiency and instantaneous carboxylation efficiency allowed greater development of plants treated with thiamine. In addition, the application of thiamine is advantageous in cases where planting is carried out under conditions of low base saturation, followed by an adequate supply of nutrients or systems in which there is a partial or total correction of the soil chemical characteristics, promoting the development of plants and increased physiological activity.","PeriodicalId":55957,"journal":{"name":"Revista de Agricultura Neotropical","volume":" ","pages":""},"PeriodicalIF":0.3,"publicationDate":"2022-09-14","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"45665809","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}

There was a linear increase in NL and FLM according to the increase in the spacing between rows. A quadratic effect of spacing was observed on ILD, IFM, and YLD.
