Two field trials were conducted to determine the effect of P-K solubilizing bacteria and nitrogen chemical fertilizer on growth, yield nitrate in leaf mustard greens Brassica juncea L.) cultivated acid sulfate soils. Eight bacterial strains composed 3 Acinetobacter calcoaceticus 5 Rhizobium sp., liquid directly watered into plant at stages [6, 12 21 days after planting] during vegetable cultiva...

The organization and transcriptional control of chromosomal cat genes (required for dissimilation of catechol by the beta-ketoadipate pathway) in the Pseudomonas putida biotype strain (ATCC 12633) are reported. Nucleotide sequence reveals that catR is separated by 135 bp from the divergently transcribed catBC,A; catC begins 21 nucleotides downstream from catB, and catA begins 41 nucleotides dow...

Nitrogen-fixing bacteria (rhizobia) form a nodule symbiosis with legumes, but also induce certain effects on non-host plants. Here, we used a split-root system of barley to examine whether inoculation with Rhizobium sp. strain NGR234 on one side of a split-root system systemically affects arbuscular mycorrhizal (AM) root colonization on the other side. Mutant strains of NGR234 deficient in Nod ...

application of biofertilizers, especially plant growth promoting rhizobacteria (pgpr) is one of the most important strategies for plant nutrition compared to chemical fertilizers, especially in sustainable management of agroecosystems. in order to evaluate the effect of pesodomonas bacteria strains and chemical phosphate fertilizer on yield and yield components of wheat the kavir cultivar an ex...

in order to investigate the role of bacillus cogulans on yield of two forage corn cultivars, an experiment carried out at agricultural research center of tehran province during 2009-2010. the experiment design consisted of three randomized complete blocks in a factorial arrangement. investigated treatments consisted of the kind of phosphorus and cultivar. the phosphorus factor included of the a...

Plant growth-promoting rhizobacteria (PGPR) increase plant growth and crop productivity. The inoculation of plants with a bacterial mixture (consortium) apparently provides greater benefits to plant growth than inoculation with a single bacterial strain. In the present work, a bacterial consortium was formulated containing four compatible and desiccation-tolerant strains with potential as PGPR....

Black gram is one of the most indispensable components world food basket and growth health crop get influenced by biotic abiotic factors. Beneficial phyto-microbes are among them that influence growth, more particularly seed borne microbes comparatively beneficial, they pass from generation to associated with plants establishment development. In present study, twenty seed-borne yeasts were char...

A field experiment was conducted during the Rabi season of 2020-21 and 2021-22. The laid out in split-split plot design with 27 treatment combination comprising three moisture conservation practices viz. flat bed 2.5 t/ha crop residue, narrow furrow t ha-1 residue broad main seed inoculation control, rhizobium PSB sub zinc level kg Zn 5.0 sub-sub plot. Result shows that produced significantly a...

Introduction of the Sym plasmid pRL1JI into the cured Rhizobium leguminosarum bv. trifolii strain RCR5 resulted in a strain, designated RBL5523, that was expected to nodulate plants of the pea cross-inoculation group. However, effective nodulation occurred only on Vicia sativa plants, not on V. hirsuta or Pisum sativum. After random Tn5 mutagenesis, a derivative of RBL5523 was isolated that eff...
