“…The symbiosis of Rhizobium and inoculation of mycorrhizal fungi enhanced the growth of plant by supplying two major nutrients Nitrogen and Phosphorus through biological nitrogen fixation and solublizing the insoluble soil phosphate. In sustainable agricultural systems, the role of beneficial microorganisms or microbial inoculants (Yami and Khanal, 1999) in maintaining soil fertility and bio-control of plant pathogens may be more important than in conventional agriculture where their significance has been marginalized by high inputs of agrochemicals (Shrestha et al, 2010). Alternative soil management strategies are therefore needed for resourcepoor farmers to increase yields of crops, e.g.…”

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.

“…Corn is a highly responsive species and dependent on association with AMF (Miranda and Miranda 2004), maintaining mycorrhizal colonization percentages of greater than 75% in field crops (Reis et al 2012). Despite costs of maintaining mycobionts, mycorrhizal plants have higher yields of vegetative and grain biomass, as well as greater stress tolerance, than non-mycorrhized plants (Shrestha et al 2009;Farnia and Khodabandehloo 2015).…”

The influence of mycorrhization on the growth of Zea mays L. and the sclerification of foliar tissues susceptible to chewing insect attacks

The interrelationships between arbuscular mycorrhizal fungi (AMF) and plants have been the subject of numerous studies; however, whether these mutualistic associations are capable of producing structural defenses in plants for pest control remains to be determined. The present study evaluated the influence of AMF on the sclerification of foliar tissues of corn and related it to insect attack. Corn plants were grown in 5.5-L pots containing soil/sand (sterile, fertilized, pH corrected) in a greenhouse. Mycorrhized plants received propagules of native AMF; non-mycorrhized plants received soil filtrate of AMF-free soil. Some of the plants of both treatments were collected at 40 days post-emergence, while others were collected at 50 days and 60 days. Height and dry mass of the aerial part and dry mass of radicular part were evaluated. The median region of leaves of the fourth (basal) and seventh (cartridge) leaf nodes was transversally sectioned, and the sections stained, mounted in semi-permanent medium and analyzed under a microscope to measure variables related to tissue organization and sclerification. Mycorrhized plants had greater height and aerial-part dry mass. Mycorrhization influenced nine of the 15 anatomical variables analyzed with increased lignified tissue in at least one of the growth stages. It can be concluded that colonization of corn roots by AMF promotes sclerification of leaf tissues and, thus, may interfere indirectly with the plant-pest relationship by altering the quality of phytomass available for insects.
