Allelopathy is described as the interference to plant growth resulting from chemical interactions among plants and other organisms mediated through release of bioactive secondary metabolites. Since only a few studies have been reported about role seed allelopathy, an experiment was designed evaluate seeds Portulaca oleracea L. crop species common bean (Phaseolus vulgaris L.), onion (Allium cepa...

Common bean (Phaseolus vulgaris L.) can establish symbiotic associations with several Rhizobium species; however, the effectiveness of most strains at fixing nitrogen under field conditions is very low. PRF 81(T) is a very effective strain, usually referred to as Rhizobium tropici and used successfully in thousands of doses of commercial inoculants for the common bean crop in Brazil; it has sho...

in order to evaluate the effects of row spacing and seed rate on yield and yield component of common bean (phaseolus vulgaris l.) cultivars, a split plot factorial experiment based on randomized complete block design with 3 replications was conducted at second crop research station of rice research institute of iran (rasht) during 2008 and 2009. experimental factors were row spacing in three le...

Chromium was not required for normal growth of romaine lettuce (Lactuca sativa L. subsp. longifolia), tomato (Lycopersicon esculentum Mill.), wheat (Triticum aestivum L.), or bean (Phaseolus vulgaris L.) in solution culture containing 3.8 x 10(-4) muM Cr. Plants grown on this purified nutrient solution contained an average of 22 ng Cr/g dry weight. Duckweed (Lemna sp.) grew and reproduced norma...

introduction: use of unbalanced chemical fertilizers especially p, having low absorption efficiency and low solubility compounds with soil components, has resulted in the production and use of bio-fertilizers (17, 23 and 29). bio-fertilizer is a preservative material consisting of one or several specific beneficial micro-organisms or their metabolic products used to supply plant nutrients and d...

Common bean (Phaseolus vulgaris L.) is economically important for its high protein, fiber, and micronutrient contents, with a relatively small genome size of ∼587 Mb. Common bean is genetically diverse with two major gene pools, Meso-American and Andean. The phenotypic variability within common bean is partly attributed to the genetic diversity and epigenetic changes that are largely influenced...
