“…Our results show that bacterial inoculation increased seeds yield and % oil in canola seeds, this may be explained by their effect on plant growth discussed before as they can produce phytohormones (IAA and GA) which improve plant growth (El-Sawah et al, 2018 andEl-Howeity &Asfour, 2012), and also their role in providing nutrients to plants during growth stages, which reflects on the good growth of canola plants. Different species of Azotobacter could increase yield up to 50% in some crops such as rice, maize, sugarcane and some vegetables (Mazid et al, 2011).…”

Biofertilizers are recently used on a large scale to reduce chemical fertilizers and their pollutant effect on soils and water. In this work, a pot experiment was carried out to evaluate the effect of Azotobacter chroococcum, Azospirillum lipoferum and Klebsiella oxytoca with different levels of nitrogenous fertilizer on the growth and yield of canola (Brassica napus L.) and microbial population in the soil during the winter season, 2018. Results reveal that used bacterial species as biofertilizers have a great effect on morphological and yield traits of canola plants, where the plants treated with Azotobacter, Azopirillum and Klebsiella were characterized by increases in plant heights, plant weights as well as numbers of branches and pods. Also, Azotobacter and Azospirillum increased nitrogen, whereas Klebsiella oxytoca increased phosphorus in plants and seeds. The results showed that using triple inoculum (Az. chroococcum, Azosp. lipoferum and K. oxytoca) with 75% of nitrogenous fertilizer (33.75 kg N/feddan) achieved the highest seed yield per plant (24.35 g/plant), while oil percent in seeds was 46.86%, which was not the highest but very close to oil percentage in plants treated with the recommended dose of nitrogen, which was 47.47%. On the other side, using bacterial inoculum stimulate microbial population and increased total bacteria, diazotrophs (Azotobacter and Azospirillum) and phosphate dissolving bacteria counts in the rhizosphere of canola plants.

“…The literature reported the use of different bacterial genera as a feasible strategy to promote plant growth and nutrient uptake in different crops. These studies included wheat with Azospirillum, Pseudomonas, Providencia, and Anabaena [32][33][34]; sugar beet and barley with Bacillus, Paenibacillus, Pseudomonas, and Rhodobacter [26,28]; sugarcane with Herbaspirillum, Gluconacetobacter [35], sunflower with Bacillus, Enterobacter [36], rice with Pseudomonas and Chryseobacterium [37]; bean with Trichoderma [38], canola with Azotobacter, Azospirillum, and Paenibacillus [39]; maize with Herbaspirillum, Trichoderma, Pseudomonas, and Bacillus [11,40]; and soybean with Azospirillum [41]. However, only limited data were reported on PGPR colonization and growth promotion in potato plants.…”

In sustainable agriculture, seeking eco-friendly methods to promote plant growth and improve crop productivity is a priority. Humic acid (HA) and plant growth promoting rhizobacteria (PGPR) are among the most effective methods that utilize natural biologically-active substances. The aim of the present study was to analyze the effect of the presence of HA on potato (Solanum tuberosum L.) inoculation with PGPR (Bacillus megatorium and Bacillus subtilis) when compared to control and recommended doses of NPK. Seed tubers treated by humic acid (200, 400, and 600 kg ha−1) and PGPR, separately or in combination, and NPK (50% and 100%) were planted into soil and untreated soil. Treatments were assessed for plant growth, classified tuber yields, quality, and mineral contents of potato tubers. There were highly significant increases in potato growth, tuber yields, and quality in PGPR and HA inoculated crops. Tuber size, weight, specific gravity, dry matter, starch, protein, and mineral contents (except Cu) were improved with PGPR treatments and further increased when administered with humic acids. Inoculation with PGPR mixed culture and 400 kg ha−1 HA increased total potato tuber yield by about 140% while conventional single treatment of 100% NPK fertilizer only led to an increase in potato production of 111% when compared to the control. The results demonstrated that this integrated approach has the potential to accelerate the transformation from conventional to sustainable potato production.

R E S U M OO trabalho foi conduzido no período de maio a setembro de 2012, no Campus da Universidade Federal da Grande Dourados, com o objetivo de avaliar a produtividade e os componentes morfológicos e produtivos da cultura da canola (híbrido Hyola 61) submetidos a diferentes doses de nitrogênio em cobertura e irrigação. O delineamento experimental foi em blocos casualizado em esquema de parcelas subdivididas, com quatro repetições. As parcelas foram constituídas em irrigado e não irrigado. As subparcelas foram constituídas por três tratamentos com adubação nitrogenada em cobertura: 30, 60 e 90 kg ha -1 de nitrogênio. Com o uso da irrigação obtiveram-se os melhores resultados na altura de plantas, massa seca da parte aérea e no número de síliqua por planta. O teor de óleo e a massa de mil grãos apresentaram acréscimos significativos em função da irrigação e das doses de adubação nitrogenada. A produtividade sob irrigação foi superior à não irrigada, com valores iguais a 3145,65 e 1354,45 kg ha -1 , respectivamente. Productivity of canola under irrigation and nitrogen fertilization A B S T R A C TThe study was conducted in the May-September 2012 at the Universidade Federal da Grande Dourados, with the main to evaluate the productivity, morphological and productive components of canola (Hybrid Hyola 61) crop under different levels of nitrogen (topdressing) and irrigation. The experimental design was randomized blocks in a split-plot with four replications. The plots were irrigated and no irrigated. The subplots were three treatments with nitrogen (topdressing) doses of 30, 60 and 90 kg ha -1. With the use of irrigation crop attained better results in plant height, shoot dry mass and number of siliqua per plants. The oil content and thousand grain weights showed significant increases as a function of irrigation and nitrogen doses. The yield under irrigation was higher than nonirrigated, with values equal to 3145.65 and 1354.45 kg ha -1 , respectively.
