“…Superiority of the above mentioned treatments, especially T10, T11 andT12 (received half amount of mineral nitrogen), were desirable owing to their relative advantages, little cost of fertilization and reduced pollution in newly reclaimed soils. Similar results were previously recorded by Yasari et al (2008). In a conclusion T6 was superior in all studied characteristics except for number of branches/plant, seed index and oil percentage; while T4 surpassed all treatments in all traits except for plant height and oil percentage.…”

Abstract-The study was conducted in the farm of Faculty of Agriculture, Demo, Fayoum, Egypt. The soil was of loamy-sand type. During 2006During /2007During and 2007During /2008 season, using a split plot arrangement in randomized complete block design with three replicates, the work was done to determine the effect of adding biofertilizers (Azotobacter + Azospirillum, free nitrogen fixers and Trichoderma a phosphate solubilizing fungi) in combinations with mineral N fertilizer with either recommended dose (N1) or half of this dose (N2) on yield quantity and quality of two canola lines (L6 and H2). The results revealed that the two canola lines were significantly different in plant height, number of branches, number of pods and seed yield /plant. L6 surpassed H2 line for previous traits, in addition to insignificantly higher values of the other traits; T10, T11 and T12 showed superiority and high productivity with saving half of the mineral N recommended dose. For interaction; H2T10, was the best in all traits except for plant height, protein and oil percentages. H2T4, L6T6 and L6T8, for all traits except for seed index and oil percentage. The highest productivity recoded by H2T10 (N2+Trichoderma +Azotobacter), H2T11 (N2 + Azotobacter+ Azospirllum) and L6T8 (N2+ Azotobacter) which outyielded their corresponding control by 39.3, 31.8 and 23.0% a result of using only 50% of the recommended dose of N-fertilizer (N2). The latter combination was also superior in protein content (26.5%). These three combinations could be recommended as alternative method for canola fertilization, where they had economic and safely advantages.

“…More photosynthesis material was produced in plant and the number of pods in plant of sesame was increased under the effect of the mentioned fertilizer. [28] reported that application of biologic fertilizers in sesame plant significantly increased plant height, number of branches per plant, number of pods per plant, and 1000 seed weigh, and seed yield.…”

In order to investigate the effects of Barvar-2 phosphate biofertilizer and nitroxin biofertilizers on agronomical characteristics of sesame, an experiment was carried out as factorial based on randomized complete block design with three replications and two factors in Khoy city, northwest of Iran, in 2014 growing seasons. The factors were as follows: phosphorus fertilizer in three levels (control, barvar-2 phosphate bio-fertilizer with 100 kg triple superphosphate per hectare and 200 kg triple superphosphate per hectare) and nitrogen fertilizer in four levels (control, nitroxin bio-fertilizer with urea at rate of 100 kg·ha −1

“…Reports are available on the use of biofertilizers in many crop plants in increasing crop yield and nutrient uptake. Positive effects of inoculation with Azotobacter and Azosperillum on canola (Yasari et al, 2008), wheat and mustard (P. Gupta & V. Gupta, 2006), mustard (Sharma et al, 1997) have already been reported. Yasari and Rafati Alashti (2013) observed that seed inoculation with Pseudomonas fluorescens and putida resulted in increased soybean seed yield compared to control.…”

In order to compare the effects of phosphate solubilizing bacteria as biofertilizer and mineral phosphorous application in optimal date of sowing with delayed cropping date on canola (Brassica napus L.) growth and productivity, a split-plot experiment using randomized complete block design with three replications was conducted at Dasht-e-Naz Agronomy Research Station in 2014. Four levels of bacterial inoculation (Pseudomonas putida, Pseudomonas fluorescens, singly or in combination) were applied as main plots and five levels of mineral phosphorous application (0, 25, 50, 75, and 100 kg/ha of mineral phosphorous) were applied as sub plots. Canola plant were sown at two dates of sowing, one at optimal date of sowing (Sept. 30, 2014) and the other one month later as delayed cropping (Oct. 30, 2014). The results obtained showed that effects of bacterial inoculation on number of seeds per pod, number of pods on plant, and seed yield were significant at one percent probability level at both sowing dates. Moreover, rates of phosphate application had significant effects on all traits at one percent level. Comparing the means showed that application of mineral P resulted in substantial increase in seed yield. At optimal date of sowing, it was shown that while minimum seed yield obtained at control treatment (1600 kg/ha), the maximum (2980 kg/ha) obtained with interaction effects of application of both bacterial strains along with 75 kg/ha mineral P, having no statistically difference with that of P. fluorescence along with 75 kg/ha mineral P (2940 kg/ha). It was shown that delayed cropping resulted in decreasing canola growth which is reflected in seed yield and yield components. Minimum seed yield at control plot at first date of sowing (1600 kg/ha) decreased to 740 kg/ha in second date of sowing, showing 54% decrease. The maximum seed yield also decreased in delayed cropping, from 2980 kg/ha at Sept. 30, 2014 as compared to 1074 kg/ha at Oct. 30, 2014, showing a 64% decrease. The results obtained showed that an increase in P level, eventually enhanced the seed yield. This increasing trend continued until a threshold level (75 kg/ha of P), after which seed yield showed a declining fashion.
