Abstract
This research was carried out to study the effect of Azospirillum lipoferum on declining the consumption of nitrogen fertilizer on two sunflower cultivars Armawireski and Alestar at the Research Station of the Faculty of Agriculture in Baku State University. The nitrogen fertilizer was applied in four levels (0, 70, 140 and 210 kg/ha) with or without inoculation of seeds by Azospirillum bacteria. The treated seeds were inoculated with peatbased inoculants of Azospirillum lipoferum, with 2x10 7 cells per g of carrier. A factorial experiment, conducted with three replications on the base of randomized complete block design, revealed that nitrogen fertilizer inoculation with Azospirillum could lead to increase in grain yield and yield components. Using nitrogen fertilizer and bacteria together caused declining of the use of nitrogen and increasing of the grain yield. Increasing the nitrogen fertilizer amount to 210 kg/ha and inoculation led to declining of yield to less than that of 140 kg/ha treatment. The results revealed that in the case of inoculation with Azospirillum lipoferum, the highest grain yield (5.14 t/ha) was produced and without inoculation the lowest grain yield (3.68 t/ha) was obtained. The results showed that the inoculation with Azospirillum increases the yield, percentage of nitrogen in grains, number of grains in a row, flag leaf area, head length and number of grains in head. It can be concluded that by using 140 kg of nitrogen fertilizer per hectare and inoculation of maize seeds by Azospirillum could decline the application of nitrogen fertilizer, increases the grain yield up to 30 percent and prevents the pollution of environment by extended sustainable agriculture.
