Experiments were conducted in randomized blocks design. There were four different irrigation treatments including I 1 : Full irrigation; I 2 : 75% of I 1 ; I 3 : 50% of I 1 , and I 4 : 25% of I 1 ).). In 2017, dry biomass yields varied between 14.11 (I 4 ) and 26.02 t ha -1 (I 1 ), stomatal conductance between 72.2 (I 4 ) and 147.8 mmol m -2 s -1 (I 1 ), chlorophyll contents between 37 spad (I 4 ) and 42.1 spad (I 1 ), canopy temperatures between 27.2 (I 1 ) and 31.3 o C (I 4 ), and WUE between 4.5 (I 1 ) and 5.5 kg m -3 (I 3 ). In 2018, dry biomass yields varied between 14.51 (I 4 ) and 25.92 t ha -1 (I 1 ), stomatal conductance between 69.9 (I 4 ) and 129.5 mmol m -2 s -1 (I 1 ), chlorophyll contents between 39.7 spad (I 4 ) and 43.9 spad (I 1 ), canopy temperatures between 30.0 (I 1 ) and 34.5 o C (I 4 ), and WUE between 4.2 (I 1 ) and 4.9 kg m -3 (I 4 ). Based on two-year averages, dry root yields varied between 8.15 (I 4 ) and 13.27 t ha -1 (I 1 ), root/shoot ratios between 0.51(I 1 ) and 0.57 % (I 3 -I 4 ), seasonal water consumptions between 281(I 4 ) and 598 mm (I 1 ). Water stress reduced biomass yield, root yield, stomatal conductance, and chlorophyll contents, and increased WUE and root/shoot ratios. Biomass yields decreased with increase in water stress, but this decrease was lower compared to the decrease in applied irrigation water quantities.","PeriodicalId":14931,"journal":{"name":"Journal of Agricultural Science and Technology","volume":"186 1","pages":""},"PeriodicalIF":1.2,"publicationDate":"2022-11-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"80645089","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"农林科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

However, the variation for forage quality traits of grass pea remains largely unexplored. This study aimed to characterize the genetic diversity of grass pea collections from Africa, Asia, and Europe, and identify genotypes for superior agronomic and forage nutritional quality traits. The principal component analysis revealed that the first three principal components from nutritional quality parameters viz ., NDF, ADF, cellulose, lignin and ash percent, and from agronomic traits viz ., plant height, nodes per plant, leaf area, green and dry biomass accounted for the majority of the total variation. In addition, a total of 59 polymorphic alleles were detected at 11 SSR loci with an average of 5.36 alleles per locus and the polymorphic information content ranged from 0.49 to 0.76. Three accessions (IF1872, IF2177 and IF2156) with higher biomass than the check and four accessions (IF1327, IF1312, IL-10-76 and IF1307) with excellent nutritive value in both green forage as well as straw were identified. The present study revealed high genetic variation for biomass and nutritional quality traits in grass pea collections that could be useful for development of high-yielding, nutritionally rich, and dual-purpose varieties.","PeriodicalId":14931,"journal":{"name":"Journal of Agricultural Science and Technology","volume":"81 1","pages":""},"PeriodicalIF":1.2,"publicationDate":"2022-11-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"83888879","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"农林科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The sample, composed of 383 traditional ranchers, was taken by stratified random sampling. The measurement tool was a questionnaire whose face and content validity was confirmed by a panel of experts and its reliability was estimated in a pilot study by calculating Cronbach’s Alpha. The results showed that the indicators used to measure the research variables were consistent enough with the factor structure and theoretical framework of the research. It was found that normative processes had a significant positive impact on the habitual processes and intention of the traditional ranchers. Also, the effect of situational influences was positive and significant on normative processes, habitual processes, and the intention of the traditional ranchers. In addition, habitual processes and attitudes influenced intention to use biogas positively and significantly. It is concluded that the results have significant implications for the use of rigorous theoretical frameworks such as the Comprehensive Action Determination Model (CADM) when attempting to understand the intention to use biogas.","PeriodicalId":14931,"journal":{"name":"Journal of Agricultural Science and Technology","volume":"35 1","pages":""},"PeriodicalIF":1.2,"publicationDate":"2022-11-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"83479559","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"农林科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Water extract of E. suaveolens leaves and stem barks (1, 10 and 100% concentration) were independently applied on four different varieties of maize seeds (OBA 98, OBA Super 6, SAMAZ 52 and SAMAZ 47) and stored alongside maize seeds without the extract application for 6 months. The fungal growth determination was carried out on Potato Dextrose Agar (PDA) media plates by placing maize seeds from both the group to which the extract was applied and those without the extract and incubating at 28 °C for 48 hours. The results indicated that all the maize seeds that the E. suaveolens leaves and stem bark water extract was applied at a varying concentration (1, 10 and 100%), recorded no growth of A. flavus unlike the maize seeds without the water extracts application which shows the incidence of A. flavus growth. In conclusion, E. suaveolens leaves and stem bark water extracts under varying concentration of 1, 10 and 100% had demonstrated to be an effective antifungal agent against A. flavus even after 6 months post application.","PeriodicalId":14931,"journal":{"name":"Journal of Agricultural Science and Technology","volume":"1 1","pages":""},"PeriodicalIF":1.2,"publicationDate":"2022-10-10","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"88862512","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"农林科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Different crude concentrations of the plant extracts were added for the antifungal effect into wells within Aspergillus flavus swabbed in a potato dextrose agar plate to diffuse at room temperature for 2hrs and the plates were incubated at 28oC for 48hrs before measuring the diameter of the inhibition zones.
