Surveyed tomato plant showing, root rot and wilt symptoms were subjected to isolation trails for the purpose of isolation of the causal organisms. Rhizospheric samples of different healthy and diseased plants were collected at flowering growth stage for determining the frequency occurrence of different fungi associated with the root region of healthy and infected roots of tomato plants under both irrigation methods. It was observed that the Tomato plants irrigated under DI method were more prone to fungal infection than that of SBD method. Pathogenic fungi that contributed in reducing the survival of tomato plant were high in rhizospheric soil irrigated with DI irrigation Method as compared to SBD irrigation method. The root fungal pathogens isolated from rhizospheric soil were Fusarium solani, Fusarium oxysporum, Aspergillus spp., and Pythium spp., which recorded in high frequency comparing with other microorganisms. The genus Fusarium represented in highest records followed by the genus Rhizoctonia and Pythium respectively at all assayed samples.","PeriodicalId":14915,"journal":{"name":"Journal of Advances in Agriculture","volume":"4 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2018-10-25","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"81328752","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}

Additionally, an appraisal of the relationship between climate variables, potential evapotranspiration and cotton yield was done based on regression models. Multiple linear regression models based on climate variables and potential evapotranspiration could be used as a simple tool for the prediction of crop yield changes in response to climate change in the future. The CropSyst simulation under SRES B1, resulted in an increase by 6% for the period 2020-2050 and a decrease by about 15% in cotton yield for 2070-2100. For the earlier planting date a higher increase and a slighter reduction was observed in cotton yield for 2020-2050 and 2070-2100, respectively. The results indicate that alteration of crop management practices, such as changing the planting date could be used as potential adaptation measures to address the impacts of climate change on cotton production.","PeriodicalId":14915,"journal":{"name":"Journal of Advances in Agriculture","volume":"29 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2018-09-29","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"90628510","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}

Appropriate fertilization is one of the methods that can help to suppress the pests’ presence in the field. In general, insects’ pests are attracted to the plants that are supplied with excess supply of nutrient as it can help them to develop better in future as these nutrient play their roles in aiding through growths and insects’ fecundity. Data on nutrient status were collected were Phosphorus (P), Potassium (K), Calcium (Ca), Magnesium (Mg), Copper (Cu) and Zinc (Zn). These data had been collected twice per month which were at the middle and at the end of each month. Four samples of leaves were taken from four sampling oil palm trees of each treatment. Leaves from ninth or seventeenth fronds were chosen as it is the best most ideal fronds to be used for leaf analysis to identify the nutrient content. The result of this study showed that Phosphorus (P) exerted a strong positive relationship with the presence of Oryctes rhinoceros in the oil palm while Potassium (K) showed a strong negative relationship between the two variables. Thus, developing awareness to the growers to this nutrients-balancing issue would be good for future agriculture in future as it is clear now that balanced nutrition is primordial to ensure availability of nutrients uptake by plants.","PeriodicalId":14915,"journal":{"name":"Journal of Advances in Agriculture","volume":"278 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2018-08-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"75404748","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}

Six week old plants were treated with 100, 50, and 25 mmol/L NaCl on a weekly basis and they were simultaneously treated with 5-ALA at a concentration of 5% by foliar spray. The effect of foliar ALA application on plant growth, chlorophyll contents and internal ALA concentration was studied. The internal ALA shoot concentrations ranged between 27.50±2.12 and 34.35±1.48 µg g-1 dry weight with no significant difference (p<0.05) recorded between plants treated with NaCl alone and those treated with both NaCl and ALA. The concentrations of chlorophyll a and b were elevated only in tomato plants treated with NaCl and ALA, whereas their levels decreased in plants treated with NaCl only. An adverse significant effect (p<0.05) of salinity stress was recorded on plants length, number of leaves, shoot and root fresh and dry weight. However, no significant difference (p<0.05) was observed in plants treated with NaCl alone with those treated with NaCl plus ALA in comparison to the control. The results of the present study suggested that foliar ALA treatment had no effect on the Na and Cl uptake, the internal ALA concentration, and had no role in adverting the effects of salinity on plant growth. The present study has proven that foliar ALA is directly used by the plant for the synthesis of chlorophyll in order to increase the photosynthetic rate and thus to help tomato plants to survive the salinity stress.","PeriodicalId":14915,"journal":{"name":"Journal of Advances in Agriculture","volume":"AES-7 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2018-08-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"84490210","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}

Laboratory experiments were set up at Coffee Research Institute, Ruiru-Kenya between 2014 and 2017. The set up was in a completely randomised design, replicated three times and repeated once. Third leaf pair explants were excised from 8-month-old greenhouse-grown mother plants and cultured in half strength Murashige and Skoog basal salts augmented with Thidiazuron. Once embryos had developed, the cultures were analysed for endogenous substances using HPLC and GCMS. Sucrose, phenolics, alkaloids, amino acids, fatty acids and their derivatives correlated positively, whereas fructose and glucose correlated negatively with the other biochemical components. Endogenous sucrose, chlorogenic acid, caffeine amino acid, fatty acids and their derivatives are potential biomarkers for coffee somatic embryogenesis, whereas endogenous fructose and glucose are inhibitors of the same. Further studies regarding the status of the biochemical components, especially in particular stages of embryo development should be conducted to establish treatments that can improve coffee direct somatic embryo development.","PeriodicalId":14915,"journal":{"name":"Journal of Advances in Agriculture","volume":"222 1","pages":"1309-1338"},"PeriodicalIF":0.0,"publicationDate":"2018-05-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"78434510","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}
