This practice is impacting \u0000negatively on the health of the citizenry and local producers continue to face daunting obstacles \u0000posed by activities of smugglers. This study analyzed the factors influencing urban households’ \u0000Willingness To Pay (WTP) for Nigeria Processed Chicken (NPC) in Kwara State. Data used for the \u0000study were obtained from 274 respondents using the multi-stage sampling techniques. They were \u0000analyzed using descriptive statistics and Probit regression. From the study, it is seen that the \u0000majority of the respondents (54.7%) were fairly educated with mean year of schooling of 12.97. \u0000About 34.7% and 13.9% of the respondents had below N50,000 and above N200,000 respectively \u0000as their total monthly income. The result indicates that over 80% of the respondents claimed that \u0000NPC was not readily available while the mean distance to sales outlets stood at 3.21 km. The \u0000probit estimation of willingness to pay increased significantly with education and income and \u0000decrease with distance to sales outlets. It was recommended that policies that will enhance \u0000respondents’ purchasing power should be pursued in order to encourage them to pay for Nigeria \u0000processed chicken. Also, the creation of more sales outlets for NPC should be considered.","PeriodicalId":7714,"journal":{"name":"American Journal of Experimental Agriculture","volume":"216 1","pages":"1-7"},"PeriodicalIF":0.0,"publicationDate":"2016-01-10","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"72998348","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}

A sample size of 80 respondents for the two districts was used. The data was analyzed with SPSS 16.0 software, and descriptive statistics was used to interpret the results. In the trend analysis, three forecasting models such as linear trend model, quadratic trend model, and exponential growth model were used to find the best fitted model for area coverage, production, and productivity of white lupin. Forecasting errors namely mean absolute percentage error; mean absolute deviation and mean squared deviation were used as model selection criteria. \u0000Results: The study areas showed significant difference (p<0.001) for production and utilization practices. \u0000About 82.5% and 66.7% of the respondents at Banja and Machekel districts respectively replied on consumption of snack as supplementary food. Farmers produce the crop with minimum or no cultural practices. About (40%) respondents intercrop white lupin with other crops. Farmers use their own seeds; lack of production packages, late maturity, disease and stepwise postharvest processing are the major constraints. The quadratic model, due to its lowest values of the forecasting errors, was best fitted to predict the future estimate of area, production, and productivity of white lupin. \u0000Conclusion: If the current production practices remain unchanged, decreasing in total area coverage, production and productivity will continue. Therefore, for better utilization of this potential crop, the current indigenous farmers’ practices need to be supported by research based technologies of production and utilization.","PeriodicalId":7714,"journal":{"name":"American Journal of Experimental Agriculture","volume":"8 1","pages":"1-14"},"PeriodicalIF":0.0,"publicationDate":"2016-01-10","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"78592610","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}

Shatabdi). Study Design: The experiment was designed with six boron treatments, arranged in a randomized complete block design (RCBD) with three replications. Place and Duration of Study: The field trial was conducted at Bangladesh Agricultural University (BAU) farm, Mymensingh during 27 November 2010 to 24 March 2011. Methodology: The B treatments were (i) B control, (ii) soil application of B, (iii) seed priming into boric acid solution, (iv) foliar spray of B at primordial stage of crop, (v) foliar spray of B at booting stage and (vi) foliar spray of B at primordial and booting stages. The rate of B for soil application was 1.5 kg B ha from boric acid (17% B) and the rate for each foliar spray was 0.4% boric acid solution. Seed priming was done by soaking wheat seeds into 0.1% boric acid solution for 10 hours and then seeds were dried before sowing. Every plot received 115 kg N, 25 kg P, 75 kg K and 15 kg S per hectare from urea, TSP, MoP and gypsum, respectively. Original Research Article Fakir et al.; AJEA, 12(2): 1-8, 2016; Article no.AJEA.24286 2 Results: The treatment receiving foliar spray of B at both primordial and booting stages of the crop performed the highest yield (3630 kg ha) which was statistically similar with the yield recorded with foliar spray of B at booting or primordial stage of crop and with soil application of B before crop (wheat) was sown; all the yields were significantly higher over the yield noted with seed priming or control treatment. The control treatment (no B application) had the lowest grain yield (2600 kg ha) which was significantly lower than the yield observed with the seed priming treatment. Conclusion: Wheat yield was affected due to grain set failure induced by boron deficiency and it was possible to overcome this element deficiency by soil application at 1.5 kg B ha or foliar application of 0.4% boric acid solution at primordial or booting stage of crop.","PeriodicalId":7714,"journal":{"name":"American Journal of Experimental Agriculture","volume":"80 1","pages":"1-8"},"PeriodicalIF":0.0,"publicationDate":"2016-01-10","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"77431047","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}
