There is an urgent need for more tolerant crops that are capable to stand and cope with adverse climatic conditions and for diversification of crops in the farming systems.

R.Br.). An experiment was carried \u0000out in two sites (Koibatek and Marigat) in Kenya to estimate the losses in grain yield due to head \u0000smut at varying levels of susceptibility in 50 promising advanced pearl millet genotypes. The test \u0000germplasm were planted in a complete randomized block design (RCBD) in three replicates during \u0000the short rains (Sept -Dec 2011) and long rains (April-July 2012). To assess the yield loss, two \u0000experiments were set as sprayed with fungicide to control disease and unsprayed. Results showed \u0000that among the tested genotypes, KAT PM1 and ICMV 221 were resistant checks and showed \u0000minimum yield loss as compared to the susceptible genotypes, (SDMV 94001 and SDMV 94014) \u0000which had highest yield loss. The mean grain yield loss varied between 6.5 and 60.8% in different \u0000genotypes. Both incidence and severity of the disease were significantly and positively correlated \u0000with losses in grain yield but severity contributed more. The prediction models for estimating yield \u0000losses were derived from yield in protected plots compared to none protected plots. Results showed \u0000that yield and disease severity were highly significant among the genotypes tested (Fpr <0.001) with \u0000yield ranging from 1172-4122 kg ha-1. Overall mean yield for both the seasons in the two sites was \u00002650 kgs ha-1 for the sprayed experiment and 2390 kgs ha-1 in the diseased plots. The overall yield \u0000loss due to head smut was 18%. High yielding genotypes were SDMV 90031, IP 8783, SHIBE, \u0000ICMV 96603, ICMV221-1, IP6791 and ICMV 221 Bristled.

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}

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}
