Therefore, there is a growing trend among present researches to explore low cost, effective fertilizer substitutes for inorgnaic fertilizers in cropproduction. Human urine is a liquid waste rich in essential plant nutrients such as nitrogen, phosphorous and potassium. This study was conducted to explorethe possibility of utilizing human urine in edible crop production as a low cost and effective nitrogen fertilizer. The study was conducted in a greenhouse using bushita bean (<em>Phaseolus vulgaris</em> L.) as crop species. Five treatments: T1 (Albert solution), T2 (Agriculture department recommendation for nitrogen (N), phosphorous (P), potassium (K) fertilizers; Urea, TSP and MOP), T3 (Human urine; nitrogen concentration adjusted to 20% less than the nitrogen concentration in T2), T4 (Human urine; nitrogen concentration adjusted similar to T2), and T5 (human urine; nitrogen concentration adjusted to 20% more than the concentration in T2) were applied three weeks after planting. Results revealed that T5 showed the highest increase in plant height, leaf area, root dry weight and total nitrogen content of leaves. Bean yield was significantly higher (p<0.05) in plants received T1 and T2 compared to urine-fertilized treatments. Even though, bean yields of urine-fertilized treatments (T1, T2 and T3) not directly comparable to that in the industrial-fertilized treatments (T1 and T2) were at a satisfactory level. The urine treatments were more cost effective than T1 and T2. Based on the results, we suggest that urine can effectively be used as a nitrogen fertilizer substitute in agricultural production.</p></div>","PeriodicalId":20478,"journal":{"name":"Procedia food science","volume":"6 ","pages":"Pages 279-282"},"PeriodicalIF":0.0,"publicationDate":"2016-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://sci-hub-pdf.com/10.1016/j.profoo.2016.02.055","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"90838191","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Thus, several Commercial Tea Plantation companies have voluntarily suspended the use of many Herbicides on Tea under their charge, which are still permitted to use in Sri Lanka. Intense emergence of Herbicide tolerant weed species on treated areas was noted in the mean time, although this crucial factor had been remained un-noticed as a result of frequent manual weeding under taken by the Tea estates under various other accounts such as plucking, fertilizer application, mossing and ferning green manure etc. Therefore, an investigation was carried out to ascertain the affectivity of Herbicides recommended for Commercial Tea Plantations, over a period of 24 months in Hapugastenne Tea Garden, Maskeliya, since year 2012 at five different elevations, with five replicates set at each elevation. Results show that over 20 weed species out of 23 acutely problematic weeds which cause great damage to Tea crop, are entirely tolerant to Diurone, Paraquat and Glyphosate and cannot be controlled by using said Herbicides. It was further revealed that such weed species have the ability to turn a Tea Plantation into a totally unproductive and economically non-viable unit within a time period of one to two years depending on the herbicide tolerant weed species present. These weeds are capable of suppressing the growth of the Tea bushes by making them stunted in growth with poor bush frames, turn the foliage yellowish and induce defoliation, unless they were removed completely by manual uprooting.</p></div>","PeriodicalId":20478,"journal":{"name":"Procedia food science","volume":"6 ","pages":"Pages 318-322"},"PeriodicalIF":0.0,"publicationDate":"2016-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://sci-hub-pdf.com/10.1016/j.profoo.2016.02.063","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"78122147","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

More specifically, this work provides important insights in mycotoxin contamination of these spices and associated risks in Sri Lanka. Firstly, a simple extraction method based on the QuEChERS approach was developed and successfully validated for the simultaneous determination of multiple mycotoxins using an advanced chromatographic technique, LC-MS/MS. The method was applied on complex spices for quantitative screening of seventeen mycotoxins. In addition to the classical aflatoxins and ochratoxin A, the spices were also found to be contaminated with several other toxicologically significant mycotoxins. Chilli samples (87%) were more frequently contaminated with mycotoxins than peppers (65%). Subsequently, the mycotoxins screening results and the collected consumption data were integrated in a quantitative risk assessment study. The results showed that AFB1 exposure via chilli consumption is of a public health concern in Sri Lanka, pepper is of lesser extent a risk due to the lower consumption. The toxigenic mould characterization in black peppers showed that Aspergillus flavus and/or Aspergillus parasiticus were the predominant moulds (73%) found, with considerable contamination (60%) of Penicillium spp. and A. niger. Furthermore, predictive mould growth models on peppercorns were developed at three temperatures and seven water activity levels for both A. flavus and A. parasiticus isolates. Based on the research, suitable storage conditions for black peppercorns were suggested and the way forward in managing the risk towards mycotoxins posed by the consumption of these two spices in Sri Lanka.</p></div>","PeriodicalId":20478,"journal":{"name":"Procedia food science","volume":"6 ","pages":"Pages 326-330"},"PeriodicalIF":0.0,"publicationDate":"2016-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://sci-hub-pdf.com/10.1016/j.profoo.2016.02.065","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"85124783","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

As the rice is staple food of Sri Lankans, it is essential to identify the impacts of climate changes on country's rice production. This study was conducted to identify the yield and growth changes of most popular two rice varieties (At362 and Bg357) cultivated in Nilwala river basin at <em>Yala</em> season under the global climate change scenario Representative Concentrate Pathway (RCP) 8.5. The Decision Support System for Agro technology Transfer (DSSAT) software is used to forecast the rice yield for <em>Yala</em> season in mid-centuries. To simulate the rice yield DSSAT requires data sets of crop growth and management, daily weather data and soil data. Crop management data were obtained from an experiment which was conducted in Palatuwa area at Nilwala downstream in Matara district. Daily weather data were collected from Mapalana weather station and soil data were collected from wet zone soil classification. Model was calibrated using experimental data for <em>Yala</em> season 2014 and model was validated using collected data in <em>Yala</em> season 2013. Future yield was predicted using forecasted weather data under climate change scenario RCP 8.5 for Mapalana area. The results show that increasing temperature and solar radiation and decreasing rainfall in mid-centuries affects both yield and growth of rice. Grain yield in mid-centuries shows decreasing trend in both varieties by 25% to 35% than the yield at 2014 and growth period will be shorter than the present conditions.</p></div>","PeriodicalId":20478,"journal":{"name":"Procedia food science","volume":"6 ","pages":"Pages 159-163"},"PeriodicalIF":0.0,"publicationDate":"2016-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://sci-hub-pdf.com/10.1016/j.profoo.2016.02.039","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"83484753","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
