The experiment was conducted at Horticulture Garden, Department of Horticulture, Institute of Agricultural Sciences, Banaras Hindu University, during 2015-2016. The results of the present study indicated that the scion Langra performed the best for the two graft success parameters (GSPs)—the sprouting time and % graft take success and the two graft growth parameters (GGPs)—the scion-shoot girth and the number of leaves per plant; Chausa for the % graft survival and Bombay Green for the scion-shoot length. Amrapali was observed to perform the worst for the % graft take success, the scion-shoot girth and the number of leaves per plant, while Mallika performed the worst for the sprouting time, the % graft survival and the scion-shoot length. The grafting performed on the root-stock at age six months showed the worst for all the GSPs and GGPs. The grafting done on the root-stock at age two months performed the best for all the GSPs and GGPs, except the scion-shoot girth for which the grafting done on one month old root-stock was found to be the best.","PeriodicalId":312861,"journal":{"name":"Journal of Agricultural Science and Technology B","volume":"48 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2019-05-28","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"125931346","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}

Cheddar has an English origin, while Kefalotyri is a traditional cheese in Greece and a well-consumed dairy product in Cyprus. Discrimination of dairy products can be determined through several chemical methods. The aim of this study was to discriminate the samples of Cheddar and Kefalotyri cheese by analyzing various samples, from different brands. Two spectroscopic techniques namely proton nuclear magnetic resonance (H-NMR) and Fourier-transformed infrared (FTIR) spectroscopy were chosen in order to chemically characterise the samples. The first step of the methodology was the freeze-drying process for lyophilisation of the samples. The number of samples reached 28, including 14 Cheddar samples and 14 samples of Kefalotyri cheese. After that, measurements for each sample have been obtained by FTIR (% transmittance-wavenumber in cm) and H-NMR (signal intensity-chemical shift in ppm) techniques. The data were analysed using SIMCA software. The proposed techniques along with chemometrics allow the discrimination of those two types of cheese. Both techniques employed are of significant importance, since they provide information about good classification of the samples when they are combined together. Interpretation of results and classification by using chemometric methods confirmed the different recipe of the two types of cheese. This study is the initial step of the future work. Future research will focus on discrimination based on the species’ origin of milk of these and other cheese samples.","PeriodicalId":312861,"journal":{"name":"Journal of Agricultural Science and Technology B","volume":" 3","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2019-05-28","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"113951136","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}

Emerging non-thermal pasteurization techniques are applied in order to avoid thermal processes maintaining the microbial safety and quality of liquid foods. Non-thermal preservation technologies used in the liquid food industry include high-pressure processing (HPP), pulsed electric field (PEF), ultraviolet light (UV-C) and ultra-sonication (US). HPP is a method to target specific organisms by applying a pressure range of 100-1,000 MPa. PEF uses short pulses of a strong electric field applied to a flowing liquid food which affects the whole cell membrane of the organism. UV-C treatment at 253.7 nm has been proven to be appropriate for maintaining liquid quality and minimal deterioration of nutrients. US is applied to liquid foods in a lower frequency range of 20-100 kHz and a higher sound intensity of 10-1,000 W/cm to the breakdown of cells. According to scientific literature, those methods have been applied to fruit juices like orange, apple, pear, coconut water, etc. Most of the non-thermal methods achieved the Food and Drug Administration (FDA) requirement of a 5-log reduction of microorganisms without deteriorating the sensory and nutritional attributes of fruit juices. Some of these methods have already been commercialized and others are still in a pilot scale. This study gives a comprehensive overview of published literature regarding the potential for using non-thermal pasteurization methods to extend the shelf life of different fruit juices with minimal deterioration of nutritional and sensory quality.","PeriodicalId":312861,"journal":{"name":"Journal of Agricultural Science and Technology B","volume":"51 9","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2019-05-28","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"120920935","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}

Animal protein production has been increasing with global demand for meat with meat quality a major concern, especially for more demanding consumers who are looking for quality products to meet their needs. The quality of the meat is the result of what happened to the animal throughout the production chain, that is, good rearing conditions result in a better meat quality. Different types of stress can be harmful to animals due to inadequate or improper animal handling on farms, inadequate transport conditions, poorly maintained trucks and roads, and conditions that agitate animals can lead to bruising, thermal stress. The stress in animals occurs when they are in adverse conditions and can significantly compromise meat quality loss. As an example, stress can significantly affect meat quality parameters as drip loss (DL), meat color, change ultimate pH and cause meat anomalies. Among the main parameters of evaluation used for meat quality are color, characterized by luminosity (L*, a*, b*), lipid and protein oxidation, pH, water holding capacity (WHC) and softness. Producing and processing high-quality meat is a challenge since it is necessary to apply methods that promote comfort in a complete sense, in a way that minimizes inducing significant stress. Based on the results presented it is remarkable that stress alters the meat quality, compromising the main attributes that involve it, like color, pH, WHC, Warner-Bratzler shear force (WBSF), lipid oxidation, among others andis necessary to avoid or reduce stress caused during the production of the animals to ensure a high-quality meat, resulting in greater profitability for the producer.","PeriodicalId":312861,"journal":{"name":"Journal of Agricultural Science and Technology B","volume":"35 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2019-05-28","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"130634180","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}

In the early years of Nigeria’s independence, cash crops such as rubber, cashew, groundnut and oil palm were the major crops around which the economy revolved. Today, there is a shift to alternatives for biofuel, pharmaceutical starch and derivatives using root and tuber crops, which have continued to play a significant role in the agricultural revolution of the country. The current agricultural transformation agenda in Nigeria is intended to engineer the bulk of root and tuber crops in the country into value-added products to match the increasing new tastes and demands for products across the globe. It is also intended to provide job opportunities and to generate additional income for low-income earners, especially in the rural areas. There is, therefore, the need to intensify research efforts aimed at exploring the potentials of major and minor root and tuber crops to ensure food security. In this review, six (6) major root and tuber crops, namely cassava ( Manihot esculenta Crantz), yam ( Dioscorea spp.), sweet potato ( Ipomoea batatas (L.) Lam), potato ( Solanum tuberosum L.), cocoyam ( Xanthosoma sagittifolium Schott) and ginger ( Zingiber officinale L . ) as well as three (3) minor ones, namely the Hausa potato ( Solenostemon rotundifolius (Poir) J. K. Morton), Livingstone potato ( Plectranthus esculentus N.E.Br.) and the Polynesian arrowroot ( Tacca leontopetaloides (L.) Kuntze) were examined. In spite of the numerous benefits derivable from these crops in terms of nutrition and medicinal values, some have been neglected to the extent that they are classified as orphan crops. Therefore, much more attention should be accorded to these crops, which have the potentials to contribute to food security in Nigeria.","PeriodicalId":312861,"journal":{"name":"Journal of Agricultural Science and Technology B","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2019-04-28","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"129692440","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}

The agronomic performances, genetic variation and histological analysis of the elite mutant lines were investigated at M 2 generation in comparison with the control. Significant differences were observed from the previous three evaluations of the eight mutants. Nine plants, including the control and eight mutants, had little difference in the number of flowering days from July 23 to July 25. The leaf shape of the control was entire, while the leaf shape of the mutant was palmate. Of the eight lines, M 2 IT20-5 showed better performance in regard to diameter, dry weight and seed weight per plant. The random amplified polymorphic DNA (RAPD) analysis produced a genetic diversity of 72.7% within the genotypes used. A dendrogram was constructed based on the RAPD fragments. Differentiation was demonstrated between the control and kenaf mutants. Taken together, the mutant line, M 2 IT20-5, can be useful as a resource for high biomass production.","PeriodicalId":312861,"journal":{"name":"Journal of Agricultural Science and Technology B","volume":"130 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2019-04-28","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"116370348","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}

Social networks in eight fishing settlements of Rivers State were purposively selected to assess the role of networks on access and use of information and gear among the shrimp fishers. The cross-sectional study used mixed methods to elicit data. Data obtained were subjected to content analysis and MAXQDA 2018 software to generate project maps showing information and fishing gear accessed and used. Results show that 24.8% (31) of respondents joined social network due to information sharing behavior of network members. Information was shared through one-on-one interactions, group meetings, fish buyers and phone calls. Out of the 96.8% (121) of respondents belonging to shrimp fishers’ network, 23.2% attended meetings for at least four times a month while 22.4% attended meetings for more than four times a month. Information shared bordered on price of shrimps, weather and tide, fishing grounds and traps, water level, timing of fishing and processing techniques. Respondents revealed that information shared in their networks was correct, adequate and timely. Fishing gear accessed and used proficiently was dragnet, cast net and beach seine. In all, the evidence from the interview responses suggests that networks play a key role in shrimp fishers’ access and use of information and fishing gear. Fishers are therefore, encouraged to be in one network or the other.","PeriodicalId":312861,"journal":{"name":"Journal of Agricultural Science and Technology B","volume":"36 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2019-04-28","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"127054523","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}
