Biological fertilizers are natural inputs that can be used as complementary or alternative fertilizers in sustainable agriculture. A split plot experiment has been conducted in a randomized complete block design with three replications in Khuzestan province during 2018-19. Three different planting methods (spraying), linear and atmospheric and stack plots in main plots and three levels of application of 100% urea, 70% urea plus 100 g Azotobacter, 50% urea plus 100 g Azotobacter in plots. Sub-comparisons. The results of analysis of variance showed that the main effects application of urea fertilizer plus azotobacter and planting pattern had a significant effect on number of pods per plant, number of seeds per pod, grain yield, protein percentage, parietin yield. The use of 70% urea plus Azotobacter significantly increased the yield of rapeseed oil but was in a class with 100% urea treatment. The use of 70% urea plus Azotobacter significantly increased the yield of rapeseed oil but was in a class with 100% urea treatment. Interaction between sowing pattern and the combination of urea and aztobacter had a significant effect on grain yield and biological yield. The most appropriate yield of method planting furrow and 70% of urea with azotobacter application. In this study, considering the 25% savings in nitrogen fertilizer consumption, in addition to 33% increase in canola quality, it reduced the costs by 30%, which is economically viable and recommended.

Effect of nano titanium oxide, nano zinc and multiwall carbon nano tube on yield and yield components of green gram was carried out in Kohkiloyeh-Boyrahmad province, Iran with 30 degrees 45' N and 50 degrees 44' in 2013 growing seasons. The experiment was arranged as factorial in a completely randomize block design with three replications, treatments including: four concentrations (zero, 50, 100 and 200 mg/l) of above nano particles, were spraying on green gram plants at 4-2 leaf, 8-6 leaf stages and pod stage. The results showed all of nano particle treatments had significant effect on some yield components of green gram plants. Concentrations of multiple carbon nano tube at 50, 100 and 200 mg/l had significant effect on number of pod/plant, seed thousand weight and biological yield, also nano titanium oxide at 50 mg/l had positive effect on grain yield. The harvest index, the number of grain/pod and seed protein percent was higher under 50 and 200 mg/l of nano zinc treatments. In conclusion, the spraying of 50 mg/l of above nano particles had the highest effect on yield and its components of green gram.

In order to evaluate the variation of some of quantitative and qualitative traits of different varieties of linseed under different plant densities, an experiment was conducted in the research station of the Faculty of Agriculture in Shahrekord Univerity in 2009. This experiment was arranged as factorial in RCBD design with three replications. Four linseeds originated from Australia, Canada, France and Iran varieties were used as the first factor, and three plant densities of 300, 500, and 1000 plants per m2 were used as the second factor. Based on the results of this experiment, except for traits of seed number per capsule, 1000 seeds weight days to maturity and protein percent, other traits such as plant height, grain yield and oil content significantly responded to the plant density. The highest plant height and maximum grain yield at 1000 plants per m2 and the greatest amount of oil content at density of 500 plants per m2 were produced. All measured traits had significant effect in different linseed varieties. The highest plant height in Canadian linseed, he maximum grain yield, and days to maturity in Iranian linseed, the greatest amount of protein in France linseed and the maximum oil content in Canadian linseed were observed. Except for the trait of seed number per capsule, 1000 seeds weight, days to maturity, others including plant height, grain yield, percent of protein and oil content were significantly different in the interaction between density and variety. Canadian and Iranian linseed at density of 1000 plants per m2 produced maximum plant height, Iranian linseed at density of 1000 plants per m2 produced maximum grain yield and, France linseed at density of 1000 plants per m2 produced the greatest protein percent, and Canadian linseed at density of 300 plants per m2 also produced maximum oil percent. The general result in this experiment showed that, the density of 1000 plants per m2 was the best plant density and the Iranian linseed, due to great oil content and grain yield, was the most important linseed among other varieties.
