Petroselinum crispum, popularly known as parsley, can be used for the production of biologically active essential oil. Considering the demand for novel natural products to control microorganisms, this study aimed to analyze the chemical composition and antibacterial activity of P. crispum essential oil from organic cultivation. Essential oil was extracted by hydrodistillation from the aerial part of P. crispum cv. plain (plain leaf type) at 70 days of age and analyzed for chemical composition by gas chromatography–mass spectrometry (GC-MS). Antibacterial activity was evaluated against five bacterial pathogens by the broth microdilution method. The essential oil yield was 0.02% and the major compounds were apiol (61.94%) and myristicin (9.33%). The minimum inhibitory concentration (MIC) of essential oil ranged from 1.70 to 10.00 mg mL−1, with the best activities against Staphylococcus epidermidis and Staphylococcus aureus. These results demonstrate that apiol-rich essential oil from organic P. crispum shows promise as an antibacterial agent in food and pharmaceutical industries","PeriodicalId":398198,"journal":{"name":"May 2022","volume":"16 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-05-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"121460080","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 second aim was to determine the best combination of temperature and cultivation combination for post-harvest characteristics of large chilies using non-parametric analyses. The study was conducted in Jeneponto Regency, Indonesia, at 100 meters above sea level with dusty clay soil and 21-34 °C temperatures. The study used two experimental set up. The first experiment was arranged in split-plot design with planting media (combination of soil, compost or husk charcoal) as main factor (3 level) and concentrations of coconut water as subplot (4 levels). The second experiment was the temperature conditions (the room and refrigeration temperature conditions) as the post-harvest experiment after the first experiment that arranged with a nested design. The observation parameters were consisted of 9 growth parameters in the first experiment analyzed by multivariate analyses and 2 post-harvest parameters in the second stage by non-parametric analyses. Based on the results of multivariate and non-parametric analyses, increase was observed in the cultivation technology effectiveness. The variance of growth and post-harvest characteristics of large chilies were more influenced by the coconut water than the planting media effect. Furthermore, the best concentration of coconut water in large chilli is expected to occur at 15%, with a blend of refrigeration temperature for post-harvest treatment. This value is recommended in the urban farming of large chillies, using organic applications","PeriodicalId":398198,"journal":{"name":"May 2022","volume":"181 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-05-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"123372954","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 objective of this study was to evaluate the influence of fertilization with different levels of phosphorus (P) and potassium (K) on growth and nutrient use efficiency in Tachigali vulgaris plantation. The experiment was installed in a tropical climate region in eastern Amazonia, Brazil. Three doses of P (0, 65.22 and 130.4 kg ha-1) and three doses of K (0, 100 and 200 kg ha-1) were applied in a 3 x 3 factorial scheme and randomized block design, with 4 repetitions. Growth parameters, nutrient concentration in biomass, nutrient use efficiency (NUE), and biological use coefficient (BUC) were evaluated. T. vulgaris responded significantly to fertilization with P and K in the parameters evaluated. It produced two times more biomass at the age of three years. Fertilization with 65.22 kg ha-1 of triple superphosphate and 200 kg ha-1 of potassium chloride was efficient to increase height growth by 11.1% considering the 24 months of evaluation, compared to unfertilized plants. Mg is the most efficiently utilized nutrient in the biomass components of T. vulgaris, followed by P, S, K, Ca and N. The woody compartments of T. vulgaris showed the highest BUC values, which is highly desirable and of great interest for forestry","PeriodicalId":398198,"journal":{"name":"May 2022","volume":"169 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-05-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"132060629","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}

However, there is the possibility of growing in bunches of young plants in a hydroponic system with several advantages, but different densities were not tested. The aim was to generate information on the hydroponic cultivation in NFT (nutrient film technique) of curly kale in bunches of young plants, with a study of spacing (0.07, 0.11, 0.15 and 0.20 m) and several plants per cell (one, two, three and four), aiming to improve the productivity, quality and homogeneity of kale. A split-plot experiment was executed in randomized block design, with four repetitions. Agronomic characteristics were measured, and bromatological and nutrient analyses were performed. Plant height and productivity were higher with smaller spacing. With fewer plants per cell, the leaf dimensions were higher and more homogeneous were the different plants of the same cell. With four plants per cell, it was recorded, on average, 19.3 g of fresh weight of shoot in the largest plant and 6.4 g in the smallest one. The bromatological and nutrient content was consistent with literature reports. Thus, the desired product in cultivating hydroponic kale in bunches of young plants is decisive for choosing spacing and numbers of plants per cell. Larger leaves can be harvested with fewer plants per cell than more plants per cell and vice versa. The use of smaller spacing increases productivity. The hydroponic system is technically viable to produce curly kale, providing plants with good nutritional quality.","PeriodicalId":398198,"journal":{"name":"May 2022","volume":"6 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-05-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"125012662","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 goal of this study was response of some naked barley cultivars with high yield potential using supplemental irrigation under rain-fed conditions at Al-Kasr area, Marsa Matrouh, North-Western Coast of Egypt. The growth, yield, and drought-tolerance indices of Giza 129, Giza 130, and Giza 131, barley cultivars were estimated under rain-fed and supplemental irrigation regimes (SI0: rainfall only; SI1: two supplementally irrigations at tillering and heading stages; SI2: three supplementally irrigations at tillering, stem elongation, and heading stages). Agronomic traits including yield components and drought indices for the studied barley cultivars were assessed. The results displayed that Giza 131 gave a higher performance in most studied characters under rain-fed and irrigation regimes. Also, it produced the highest tolerance index (TOL), yield index (YI), harmonic mean (HM), stress susceptibility percentage index (SSPI), sensitivity drought index (SDI), mean productivity (MP), and geometric mean productivity (GMP). MP was positively correlated with YSI, GMP, DI, and HM. So, Giza 131 cultivar was identified as a drought-tolerant genotype. Moreover, the drought tolerance indices of TOL, YI, HM, SSPI, SDI, MP, and GMP are suitable for screening cultivars with high yields under stressed and non-stress conditions. The correlation analysis between the studied traits of barley indicated that highly significant positive correlation was obtained between number of spikes m-2 and grain yield.

Furthermore, the genotyping efforts of genebanks would benefit from tools that can help to sample the accessions. A set of parameters to aid the optimization of genebanks are defined, in which Relative Balance is central. In this study, the foundation of our mathematical approach was Kullback-Leibler divergence, providing formulas with consistent properties. Two examples were used as proof of concept. The first one was the comparison between actual and putative optimal numbers of accessions in the Triticum set of the CIMMYT (Centro Internacional de Mejoramiento de Maíz y Trigo) Wheat Germplasm Bank, with 135,236 entries classified into ten groups. The second one was based on a set containing Triticum plus eight related genera, with 159,741 accessions classified into 217 end-groups, with the goal of illustrating the use of the analytical tools to optimize the ongoing genotyping process. The first example shows a scenario with a well-balanced allocation of accessions. The second example illustrates the optimized choice of end-groups to add 10,000 accessions to the genotyping process.
