in order to evaluate nitrogen fixation ability and nutrients uptake in three cultivars of common bean (phaseolus vulgaris l.) inoculating with some types of inoculants containing different strains of rhizobium leguminosarum; bv. phaseoli an experimental design was conducted in khoramdarah region in 2006 and 2007. in this investigation three types of biological fertilizers including rb117, rb123...

ADOPTION OF IMPROVED MAIZE AND COMMON BEAN VARIETIES IN MOZAMBIQUE By Helder Lopes Household adoption of new agricultural technologies, including improved maize and bean varieties in Mozambique, is still relatively low. As a result, the average maize and common bean production remains low. This study identifies factors that are associated with households’ adoption of improved maize and bean var...

Common bean (Phaseolus vulgaris L.) is an economic important crop and one of the major grain legumes for human consumption in Latin America, Africa and Asia. A morphological study of shoot induced from embryonic axes development in four Costa Rican bean varieties (Brunca, Huetar, Guaymi and Bribri) cultivated on MS media with or without 5 mg·L de N-benzylaminopurine (BAP) by scanning electron m...

Common bean (Phaseolus vulgaris) is an annual grain legume that was domesticated in Mesoamerica (Central America) and the Andes. It is currently grown widely also on other continents including Africa. We surveyed seedborne viruses in new common bean varieties introduced to Nicaragua (Central America) and in landraces and improved varieties grown in Tanzania (eastern Africa). Bean seeds, harvest...

We characterized indigenous common bean rhizobia from five districts of the state of Minas Gerais, Brazil. The isolates were trapped by two common bean varieties, the Mineiro Precoce (Andean origin) and Ouro Negro (Mesoamerican origin). Analysis by BOX-PCR of selected isolates detected a high level of genetic diversity.

The common dry bean (Phaseolus vulgaris L.) is the most widely grown food legume in Uganda, however, its production in western Uganda has been threatened by the bean root rot diseases. Resistant varieties and integrated soil and crop management package for the bean root rot disease, developed by the National Beans Research Programme, were promoted from 2003 to 2007 in Bushenyi and Kisoro Distri...

Recognizing both the stakes of traditional European common bean diversity and the role farmers' and gardeners' networks play in maintaining this diversity, the present study examines the role that local adaptation plays for the management of common bean diversity in situ. To the purpose, four historical bean varieties and one modern control were multiplied on two organic farms for three growing...

Effect of treatment with different concentrations of N-nitroso-N-ethyl urea (ENU) and etylmethan sulfonate (ЕМS) on seeds of Bulgarian common bean Dobroudjanski 7, Dobroudjanski 2, Plovdiv 10, Plovdiv 11М and snap bean Tcher Starozagorski varieties, for induction of chlorophyll mutants, was studied. It was established that investigated varieties manifested specifi c reactions to the treatment w...
