Seed production of farmers preferred improved maize varieties under community based seed production(CBSP) group initiated in the hills of Nepal under Hill Maize Research Project in 2000. Trained members of the community group produce improved seeds identified through participatory varietal selection procedures. Despite quantum jump in maize seed production, 14 tons by 7 CBSP groups in 2000 to 1...
developing reliable yet flexible software is a hard problem. although modeling methods enjoy a lot of advantages, the exclusive use of just one of them, in many cases, may not guarantee the development of reliable and flexible software. formal modeling methods ensure reliability because they use a rigorous approach to software development. however, lack of knowledge and high cost practically fo...
High seed quality is a critical component for realising yield potential. Forsmallholder cowpea farmers in northern Nigeria the informal seed system is amajor supplier of genetically high-quality seed, but the physiological quality offarmers’ produced seed remains unknown. The project “Promoting SustainableAgriculture in Borno State” (PROSAB) trained and supported farmers in seedproduction in Bo...
Whilst a formal statistical analysis of any experimental data is always preferable in principle, in the case of Pilling et al. (PLoS ONE 8:e77193, 2013), it is hard to see how the results of any formal analysis-including those provided by Schick et al.-could be considered reliable. Regardless of the issue of statistical analysis, there was a wealth of valuable and novel biological and chemical ...
1 The geographical variation of seed production, predation and abortion was analysed in Juniperus communis for 31 populations in seven distinct regions throughout the species' distribution range in Europe, including both the northern and southern boundaries. 2 The number of seeds per cone and the number of ®lled seeds per cone varied signi®cantly between geographical regions and among populatio...
An opto-electronic seed spacing evaluation system that measured time intervals between seeds and detected frontto-back location of seed drop events relative to the planter was used to rapidly determine planter seed spacing uniformity in the laboratory. The seed detection sensor for the opto-electronic system consisted of a rectangular photogate with 24 phototransistors receiving light beams fro...
nowadays, right to environment, during constitutions, court decisions and administrative procedures, in internal public law have been identified and secured. the recognition of this right in public law is dependent on normative evolutions. with the promotion of the tight to environment in constitutional norms, we can speak about the real impact of the constitutionalization in contemporary publi...
