Effect of mycorrhiza and rhizobium on <i>Phaseolus vulgaris</i> L

Abstract

Study on effectiveness of Rhizobium leguminosarum (bv. phaseoli) inoculum and mycorrhiza on red kidney bean (Phaseolus vulgaris L.), locally called Rajma was carried out in pot experiment at Nepal Academy of Science and Technology (NAST) in 2008. The parameters evaluated to study the effectiveness of inoculum application were number of nodules, biomass, number of pods, root length, shoot length and dry seed weight. The study consisted of four treatments, Rhizobium, Mycorrhizal spores, fertilizer (DAP) and control which were replicated 4 times. Rhizobium inoculated plants showed higher dry biomass, longer root and shoot length, higher number of pods and maximum nodule formation of red kidney bean in comparison to other treatments which was statistically significant (P< 0.05). Those treatments which were treated with Rhizobium inoculum and fertilizer showed nearly the same weight of dry seed than other treatments which is followed by mycorrhiza and control. Hence Rhizobium and mycorrhza can be used as biofertilizer which is economically and environmentally friendly.

Effect of Soil Properties on Arbuscular Mycorrhizae Fungi (AMF) Activity and Assessment of Some Methods of Common bean (Phaseolus vulgaris L.) Inoculation in Lubumbashi Region (DR. Congo)

“…AMF are really bio fertilizers and bio-protectors in common bean production; Abdel-Fattah et al, [27]; Abdel-Fattah et al, [28]; Sabry et al, [29] confirm also that. In pot experiment, the results are similar to those found by Neeraj and Singh [30]; Bhattarai et al, [31] showing that beans inoculated with mycorrhizae assimilate enough phosphorus and nitrogen that are beneficial for good vegetative growth and high seed production.…”

The effect of nitrogen biofertilizer and nitrogen chemical fertilizer on yield and yield components of white bean (Phaseolus vulgaris,cv.Dorsa)

“…5). In a review of the results, it was seen that the treatment which was inoculated with Rhizobium differed significantly in terms of pod quantity at a level of 5% (Bhattarai et al, 2011). In another study, it was determined that using high concentrations of urea spraying solution in plants increased the number of pods (Bahr, 2007).…”
