“…Other reports from Italy also indicated that two isolates of rhizobia induced a significant improvement of grain yield of lentil from 37% to 40% with respect to non-inoculated plants [28]. Moreover, several reports demonstrated that significantly higher yield in lentil was due to N 2 fixation [13,29,30]. Note: plt-per plant, PlH-plant height, NB-number of branch, NP-number of pod, GY-grain yield, GW-grain weight.…”

Lentil plays a major role in the food and nutritional security of low income Ethiopian families because of the high protein content of their seed; however, their productivity typically is low largely due to soil fertility limitations. Field and pot experiments were conducted during the 2011 cropping season to determine the effectiveness of Rhizobium strains on two cultivars of lentil in Southern Ethiopia. Six rhizobial inoculant treatments (four indigenous and two commercial inoculants), a nitrogen (N) fertilizer treatment (50 kg¨urea¨ha´1) and an absolute control (non-inoculated non-fertilized) were used. Inoculated plants produced significantly higher nodule number, nodule dry weight, grain yield and yield components than non-inoculated non-fertilized plants. Inoculation of field grown lentil with rhizobia strain Lt29 and Lt5 enhanced seed yield by 59% and 44%, respectively. Whereas urea fertilization enhanced yields by 40%. Similarly, grain yields were increased during the pot experiment by 92% and 67% over the control treatments by inoculation with Lt29 and Lt5, respectively. The highest levels of N fixation were achieved in plants inoculated with Lt29 (65.7% Ndfa). Both field and pot investigations indicate that inoculation of lentil with native rhizobial strains replace the need for inorganic N fertilization to optimize lentil yields.

“…in both leguminous and nonleguminous plants under field conditions (Haque and Ghaffar, 1993). Huang and Erickson (2007) observed significantly reduced incidence of damping-off, promoted seedling growth and increased root nodule mass, plant biomass and seed yield of pea and lentil due to Elkoca et al (2008) observed that seed inoculation of chickpea with Rhizobium significantly increased the seed yield under different inoculation treatments which ranged between by 18.0% to 30.5 % over the control.…”

“…They observed that fungal inhibition was more pronounced in dual culture conditions in comparison to that of cell free culture filtrate. Huang and Erickson (2007) proved that seed treatment with R. leguminosarum b.v. viceae was effective in controlling damping off in pea under naturally infested field condition. Mazen et al (2008) evaluated the antagonistic activities of the cultural filtrates of R. leguminosarum and arbuscular mycorrhiza (AM) fungi in the management of damping off and root rot diseases of faba bean.…”

Suppression of soil-borne root pathogens of arid legumes by Sinorhizobium saheli

The productivity of arid legumes in arid and semi-arid tracks remains virtually stagnant over decades because of their susceptibility to root diseases. The information on interaction of beneficial nitrogen fixing rhizobia with particular reference to arid legumes of the region is limited. Systematic studies on predominant species Sinorhizobium saheli in management of root pathogens in arid legumes were undertaken. In-vitro interactions of root pathogens and S. saheli isolated from arid legumes significantly suppressed the growth of all fungal pathogens in presence of S. saheli. In addition the growth of Rhizobium was stimulated in presence of different root pathogens. A field experiment on integrated disease managementexhibited that the maximum root nodulation with the maximum seed yield of 1325 kg/ha was observed from treatment where seeds were treated with S. saheli. Whereas, the minimum root nodulation was recorded in treatment, where a mixture of isolated fungal root pathogens were co-inoculated with S. Saheli was recorded from cowpea. The minimum seed yield was recorded from treatment wherein the mixture of isolated root pathogens of arid legumes was co-inoculated with S. Saheli due to increased disease pressure. The results of in-vitro and in-vivo efficacy of S. saheli strains suggest that their co-inoculation with PGPR's can not only reduce the use of chemical fertilizers but also can significantly enhance yields by increasing plant growth and suppressing soil borne plant pathogenic fungi.

“…Amongst the environmental factors modifying seed mass, weather and soil conditions are very important. Huang and Erickson (2007) showed that inoculation of pea seeds triggers several changes in morphological features and improves seed yield, whereas Zając et al (2013) did not observe any significant reaction of the plant to inoculation. Zając et al (2013) proved that the single seed mass significantly depends on the seed position in a pod with the seeds located in the central part of the pod having a larger mass and that the number of seeds in the pod is influenced by the node position on the stem.…”

SummaryThe development of seeds at various positions in the pod is asynchronous. Thus, the differences of seed dry mass production because of environmental conditions may depend on the cultivar type, type of inoculants and interrelations between seeds per pod, pods per plant or seeds per plant. Presently, a mathematical description of pea seed categorisation is missing. The aim of the study was the assessment of two groups of variables (quantitative and qualitative) for pea seed weight categorisation by ordinal regression model. Year, cultivar and inoculant constituted the first group (qualitative variables), whilst seeds per pod, the pods per plant and seeds per plant (quantitative variables) were entered as covariates in the ordinal regression model. According to the ordinal regression model variables, seeds per pod, pods per plant, seeds per plant, year and cultivar are meaningful predictors of the seed mass categories. However, the variable inoculant is marginally significant. Keywords
