Abstract

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. It compares 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, and 50% urea plus 100 g Azotobacter in plots. The results of analysis of variance show that the main effects application of urea fertilizer plus Azotobacter and planting pattern have a significant effect on number of pods per plant, number of seeds per pod, grain yield, protein percentage, and parietin yield. The use of 70% urea plus Azotobacter significantly increases the yield of rapeseed oil, but is in the same class as 100% urea treatment. The use of 70% urea plus Azotobacter significantly increase the yield of rapeseed oil but is in the same class as 100% urea treatment. Interaction between sowing pattern and the combination of urea and aztobacter have a significant effect on grain yield and biological yield. The most appropriate yield could be seen in the method of planting furrow and 70% of urea with Azotobacter application. In this study, this has saved nitrogen fertilizer consumption by 25% and has increased canola quality by 33% increase, reducing the costs by 30%, which is economically viable and recommended.
