The experiment was laid out as a split plot arrangement, fitted into a randomized complete block replicated thrice. The factors consisted of three tillage methods and four levels of poultry manure application (0, 5, 10, and 15 tha−1). The result revealed that tillage and poultry manure significantly (P<0.05) increased the growth and yield of sesame. Increasing the rate of poultry manure resulted in an increase in the net assimilation rate, relative growth rate, and crop growth rate. The yield in 2016 was higher than that of 2015 due to higher rainfall and residual effect of the previous cropping season. Yield per hectare was optimized using conventional tillage method and poultry manure at 15 tha−1. Although the conventional tillage and poultry manure treatments produced the highest yield, the control plot gave the highest cost and returns (return per investment) in the two years of study due to high cost of farm inputs. The result of the study further affirms farmer’s reluctance on the use of external inputs for yield enhancement in sesame.","PeriodicalId":53537,"journal":{"name":"Scientia Agriculturae Bohemica","volume":"49 1","pages":"255 - 266"},"PeriodicalIF":0.0,"publicationDate":"2018-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"45439234","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 first factor included of bacterial strain: S1= Control (without use of bacteria), S2=Azotobacter chroococcum and S3= Azospirillum brasilens and the second factor included of iron chelate: F1= Control, F2= soil application of Fe chelate, F3= foliar application of Fe chelate, F4= soil application of nano Fe chelate and F5= foliar application of nano Fe chelate. The results showed that the highest grain yield and guaiacol peroxidase (GPX) enzymes activity were obtained at the S3F5 treatment and ascorbate peroxidase (APX) at S1F5 treatment. Except the content of phosphorus in leaves and carotenoid, PGPR had significant effect on biological yield, the content of chlorophyll ‘a’ and ‘b’, yield components (number of seed per row of the ear, number of rows per ear and thousand seed weight) and nutrient elements in both the seeds and leaves. However, iron chelate, increased the yield components, but among the iron chelate treatments, the highest amount of chlorophyll ‘a’ and ‘b’ in leaves and phosphorus in seeds were obtained at F5. These results suggested that foliar application of nano Fe chelate and Azospirillum brasilens could be improvement of maize plant productivity.","PeriodicalId":53537,"journal":{"name":"Scientia Agriculturae Bohemica","volume":"49 1","pages":"245 - 254"},"PeriodicalIF":0.0,"publicationDate":"2018-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"47131857","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}

Its toxicity, mobility and bio-availability are strongly dependent on its oxidation state, Cr(III) and Cr(VI). Hexavalent form Cr(VI) is a known carcinogen with many harmful effects on living organisms, on the other hand trivalent Cr(III) form is an important micronutrient necessary for lipid metabolism. Contamination of the environment by Cr may come from anthropogenic industrial pollution or from naturally enriched sites, especially ultramafic rocks and their derived soils. Environmental conditions of soils and water represent a very complex system, which makes reliable assessment of its fate and potential toxicity and transport a really difficult task. A number of studies have been performed to describe Cr behaviour in these systems, as well as to optimize its determination, especially speciation methods. The main objective of this contribution is to summarize and present the today’s knowledge about the occurrence, speciation, and behaviour of Cr in soil environment, with a specific emphasis to description of differences between naturally enriched and anthropogenically contaminated soils.","PeriodicalId":53537,"journal":{"name":"Scientia Agriculturae Bohemica","volume":"49 1","pages":"297 - 312"},"PeriodicalIF":0.0,"publicationDate":"2018-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"45248623","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}

Information on the performance of Arabica coffee growing in the changing climate of North Sumatra has not been available so far. To provide such information, 28 genotypes were studied. The nested design used three factors. Seven climate zones, two locations in each climate zone, and two coffee farms (genotype, G) in each location were selected. The research showed that the genotypes were highly significantly different (α = 0.01). G5, G6, and G20 produced the heaviest hundred beans. G13, G19, and G25 suffered the least coffee berry borer infestation (CBBI). The length of rainy season became the most important factor (r2 = 0.54). The CBBI (y, %) correlated significantly and negatively with the elevation (x, m) with the equation of y = 46.4 – 0.025x. The climate zones showed a significant difference (α = 0.05). The genotypes produced heavy beans also in two wet months of the rainy season and one dry month. The temperature (x, °C) was the most important factor affecting CBBI (r2 = 0.65) with the equation of y = –338.2 + 15.5x. The soil pH correlated significantly and positively with beans weight and bean width.","PeriodicalId":53537,"journal":{"name":"Scientia Agriculturae Bohemica","volume":"49 1","pages":"340 - 349"},"PeriodicalIF":0.0,"publicationDate":"2018-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"41510194","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}

Frozen-thawed semen from 14 stallions was incubated either in incubator or in a water bath, diluted prior to analysis or immediatelly after thawing. The following qualitative parameters were assessed after thawing (T0) and after 30 min (T30): motility in 3 sperm subpopulations (slow, medium, fast) defined by cluster analysis of parameters obtained by Computer Assisted Sperm Analysis, viability, acrosome and mitochondrial integrity. The slow subpopulation was only significantly reduced in diluted samples in CO2 atmosphere at T0 (P < 0.05). In diluted samples the incubation time significantly affected distribution of fast, slow, and medium subpopulations in CO2 and CO2 free atmosphere (P < 0.05), respectively. Viability, acrosome and mitochondrial integrity were not affected by CO2 atmosphere (P > 0.05), however acrosome (at T0) and mitochondrial integrity (at T30) were significantly higher in CO2 atmosphere in non-diluted and diluted samples (P < 0.05), respectively.

Phengaris nausithous and Phengaris teleius belong among the flagship species associated with wet meadows and are directly threatened by the intensive agriculture practises or management abandonment. Due to their very specific lifecycle, they are closely linked to their habitats and appropriate mowing management on their patches is thus crucial for their survival. Our research took place in Dolní Labe, Děčín, Czech Republic, on 16 patches and has been performed using Mark-Release-Recapture since 2009. This paper will illustrate how intensive mowing management, applied on only one of the patches, which forms only 9.4% of total locality size, can influence the entire local Phengaris metapopulation. The selected patch was intentionally mowed in the middle of flight season annually for four years. Even though, no significant effect was identified after the first year of study, after the second and third seasons, there was evidence of population decline of both studied species.","PeriodicalId":53537,"journal":{"name":"Scientia Agriculturae Bohemica","volume":"49 1","pages":"209 - 215"},"PeriodicalIF":0.0,"publicationDate":"2018-09-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"48717548","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}
