This study investigated the effect of credit access on the adoption intensity of improved maize varieties in Osun State. A number of 150 maize farmers were selected through a multistage sampling procedure from using a structured questionnaire. Descriptive statistics, adoption index, and Tobit regression model were used to analyse the data collected. The results showed that Majority of maize farmers were over 40 years (52.6%), male (87%), and married (87%). The result also showed that majority of the farmers did not adopt improved maize varieties (55%) in the state. Swan 1 improved variety was

Cassava is the main staple crop in Nigeria. Using primary data from four south eastern states in Nigeria, the study assessed the gender impacts of improved cassava varieties. Comparative statistical analysis reveals that total female labor is higher than total male in cassava production, processing and marketing. Women spend more labor days than males for planting, weeding, harvesting, marketing and processing. The total female family labor is higher for adopters of new improved cassava varieties. There is however lower family labor input for both male and female adopters for clearing and plow

Barley (Hordeum vulgare L.) is one of the earliest domesticated cereal crops. It is used in world malt barley production, where Australia is a major exporter, representing more than 30 per cent of the world's trade. Barley is the grain of choice for malt production due to its high starch-to-protein ratio and enzyme levels that can be harnessed during germination. Malt is produced by a process called malting, which involves a three-stage controlled germination of malting barley grain. This process uses enzyme activation and de novo enzyme synthesis to modify the physical structure of the hard b

Abstract Developing countries are always looking for compact and efficient rocket stoves that burn wood efficiently and cause minimum harm to the environment. An improved design of the rocket stove and its performance as per the Clean Cook Stove Alliance procedures are reported in the present work. Previous works indicate that the square cross-section does not have a continuous air velocity. Divergent sections reduce fluid velocity and improve combustion and flow as well as reduce losses. The key features of the new design are: (a) cylindrical shape for even flow of air around the stove and im

Abstract:
Language, including local varieties, is an important component of national identity – subdialects and dialects, as well as Latgalian written language promote awareness and strengthening of regional identity and enrich the national language as a whole. Therefore, it is important that attention is paid to all language varieties. During the last decades regional varieties of Latvian language have not received sufficient coverage in learning content – there is either no information about them in learning materials or it is minimal. As a result, students not only do not acquire necessary linguistic

Abstract:
Like other crop improvement programs, a key prerequisite for the CGIAR Research Program on Grain Legumes and Dryland Cereals (CRP GLDC) to generate large-scale impact is large-scale adoption. Hence, evidencing the breadth and depth of such adoption is both of intrinsic interest and important for estimating downstream impacts, such as improved food and nutritional security, income, resilience, and soil health. While various GLDC adoption studies have been undertaken, a recent effort to systematically review these studies and synthesize the results is lacking. We undertook such a review, identif

The goals of the present research proposal were to elucidate the physiological and molecular basis of the regulation of stilbene metabolism in grape, against the background of (i) grape metabolic network behavior in response to drought and of (ii) varietal diversity. The specific objectives included the study of the physiology of the response of different grape cultivars to continuous WD; the characterization of the differences and commonalities of gene network topology associated with WD in berry skin across varieties; the study of the metabolic response of developing berries to continuous WD

Abstract:
Modern cultivated varieties carry only a small fraction of the variation present in the gene pool. The narrow genetic basis of modern crop plants is a result of genetic bottlenecks imposed during early domestication and modern plant breeding. The wild ancestors of most crop plants can still be found in their natural habitats and Germplasm Centers have been established to collect and maintain this material. These wild and unadapted resources can potentially fuel crop plant improvement efforts for many years into the future (Tanksley and McCouch 1997). Unfortunately, scientists have been unable

Abstract:
Agriculture plays an important role in sustaining rural livelihoods. Eighty-three percent of rural people are engaged in agriculture (NIS and MAFF 2014). An emerging problem facing agriculture is climate change. The anticipated impacts of climate change and variability on agriculture include changes in rainfall patterns, higher temperatures, increased frequency and intensity of flood and drought, and increased incidence of pests and disease (MOE and UNDP 2011). These serious problems emphasise the critical need for climate-smart agriculture (CSA) (FAO 2013). Among CSA techniques, the system of

Abstract:
This paper shows, using probit analysis, that low national savings increase the risk of macroeconomic crisis. Foreign savings are a poor substitute of national savings not only for domestic investment (Feldstein-Horioka result), but also for stability. It is found that deeper financial integration does not cure low investment and can improve the situation only to the extent that the risks of the foreign saving portfolio can be kept under control. Overall, a fundamental conclusion is that strong national savings are key for robust growth. Extending the probit analysis, the paper shows that the
