In Benin, rice plays a major role in the food security of the poorest rural and urban populations. However, the rice value chains have failed to achieve their potential because of some systemic constraints. In recent years, innovation platforms (IPs) have received increasing focus as mechanisms f...
En varias regiones de Nicaragua, el cultivo de arroz de secano asume un papel importante para la seguridad alimenticia de las familias campesinas, además es fuente de ingresos para éstas. Apartir del 2002, el CIRAD y el CIAT implementan en colaboración en Nicaragua un proyecto de investigación en...
Improvements in agricultural land and labour productivity are needed to meet the growing food demand and reduce farmer poverty in sub-Saharan Africa. The objectives of this study were to (i) quantify variation in labour inputs, yield and labour productivity among rice fields; (ii) elicit factors ...
Current advances in sequencing technologies and bioinformatics revealed the genomic background of rice, a staple food for the poor people, and provided the basis to develop large genomic variation databases for thousands of cultivars. Proper analysis of this massive resource is expected to give n...
The study examined the adoption rate of New Rice for Africa (NERICA), technical efficiency differentials of production of these varieties between adopters and non-adopters and the determinants. It further analysed the impact of adoption of NERICA on area cultivated, output, yield, expenditure and...
The complete nucleotide sequences of RNAs 1 and 2 of Rice stripe necrosis virus (RSNV) were determined and compared to the corresponding genomes of all sequenced, rod-shaped plant viruses. The genome organisation of RSNV RNA1 and RNA2 is nearly identical to that of Beet necrotic yellow vein virus...
Cereals and grain legumes are the most important part of human diet and nutrition. The expansion of grain legumes with improved productivity to cater the growing population’s nutritional security is of prime importance and need of the hour. Rice fallows are best niche areas with residual moisture...
