A survey for the agro-ecological distribution of Pepper veinal mottle virus (PVMV) (Family Potyviridae, genus Potyvirus) its incidence and severity on cultivated pepper was conducted between 2003 to 2005 in six agro-ecological zones in Nigeria, comprising the major pepper producing areas of the humid forest, derived savanna, southern Guinea savanna, mid-altitude, northern Guinea savanna and Sud...

The recent empirical literature on economic sustainability of certified export crops shows that certification standards that enhance yields are important for improving farm revenues and farmer welfare. However, limited evidence exists on the impact of organic certification on the adoption of agro-ecological practices. In this study, we use unique farm-level data from Ghana to examine the impact...

Sugarcane sector has a strong impact as a wealth generator for Brazil. Several authors discuss the importance of quantifying an agro-industrial system. This article aims to analyze the development of the Brazilian sugarcane sector over the past five years and to assess whether the method of mapping and quantification of agribusiness systems (GESis) is a useful tool for analyzing the economic de...

considering the current upward drift in farm use all over the world, the russian agro-food market has immense possibilities to create such economic conditions under which the farming sector could develop dynamically. the increase in the grain production is of crucial importance for all agricultural branches. in this respect, the grain sector is russia’s strategically significant economic segmen...

Amid expectations for a European ‘transition to sustainable agriculture’, there are competing transitional processes. Given the widely acknowledged harm from agro-industrial systems, unsustainable agriculture has divergent diagnoses and innovative solutions. In the EU policy context of a Knowledge-Based Bio-Economy (KBBE), there are also divergent accounts of its key terms: biological resources...

Coloured rice genotypes have greater nutritious value and consumer demand for these varieties is now greater than ever. The documentation of these genotypes is important for the improvement of the rice plant. In this study, 42 coloured rice genotypes were selected for determination of their genetic divergence using 25 simple sequence repeat (SSR) primers and 15 agro-morphological traits. Twenty...

Paecilomyces lilacinus has potential for pests control. We aimed to analyze mycelial growth and spore production in P. lilacinus strains in several agro-industrial residues and commercial media. This study suggests alternative nutrient sources for fungi production and that the biotechnological potential of agro-industrial refuses could be employed in byproducts development.
