Although Azospirillum spp. are considered to be important plant growth promoting bacteria, their possible effects on germination and vigor of aged lettuce seeds has not been previously evaluated. In fact, there is a paucity of published data about inoculation effects on seed germination. The aim of this work was to evaluate seed quality of oneyear aged lettuce (Lactuca sativa L. cv. Crimor INTA...

St. Augustinegrass (Stenotaphrum secundatum) cv FX-313 was used as a model laboratory host for monitoring population growth of the sting nematode, Belonolaimus longicaudatus, and for quantifying the effects of sting nematode parasitism on host performance in two samples of autoclaved native Margate fine sand with contrasting amounts of organic matter (OM = 7.9% and 3.8%). Following inoculation ...

to study the effects of different levels of seed ageing and bacteria inoculation on yield of common bean at field conditions, an experiment was carried out as factorial arranged in rcbd design with three replications at research farm of university of tehran (karaj-iran) in 2012. treatments consisted of four levels of seed ageing (0 (control), 3, 6 and 9 days at 41°c and 90-100% relative humidit...

Faced with the contrasting results of inoculation and co-inoculation in bean crop, an experiment was carried out pots, objective evaluating performance plant treatments inoculated or co-inoculated Rhizobium tropici Azospirillum brasilense, via seeds, without chemical treatment fungicide insecticide, combined 4 top-dressing nitrogen doses (0, 30, 60, 120 kg ha-1), a ‘Latossolo Vermelho-Amarelo d...

Two methods of soybean seeds inoculation by Rhizobium japonicum have been compared in a field experiment : i) traditional use of inoculated turf embedding the seeds; ii) use of Cephalobus parvus as bacterial carrier (3 O00 and 300 O00 nematodes per linear meter). There is no difference in yield between the inoculation methods in spite of a greater number of bacterial germs provided by nematode ...

some research indicates that n2 fixation in soybean cannot provide adequate nitrogen for proper yield. therefore, the effect of nitrogen and bradyrhizobium japonicum bacteria on some agronomic characteristics and quality of soybean cultivars was examined based on split plot in a randomized complete blocks design with three replications in 2012 at kerman township. treatments including control (w...

introduction: soil fertility management is a key factor in achieving sustainable agriculture. use of organic fertilizers is one of the methods that without environmental harmful effects with improvement of chemical and biological conditions increases soil fertility. nitroxin contains a collection of the best strains of nitrogen fixation bacteria of the genus azospirillum and azotobacter. these ...
