Abstract

Nitrogen is the most important element in plant growth and yield. There are several sources for supplying plants with nitrogen, including the use of chemical fertilizers. But excessive use of chemical fertilizers in addition to contamination of water and soil has also caused a threat to the health of the community. Therefore, optimizing the use of chemical fertilizers and replacing them with organic sources can be a step forward in improving the health of the community. For this purpose, a field experiment with different levels of urea fertilizer and various nitrogen sources was carried out in a factorial arrangement and a randomized complete block design with three replications on strawberry in 2016 at Someh-Sara, Gilan, Iran. The experimental factors included urea (0, 75 and 150 kg. ha-1) and various sources of nitrogen (Azospirilum, Azotobacter, Nano-nitrogen, and Control). Results showed that the application of urea fertilizer increased the shoot weight and shoot length, but decreased Total antioxidant capacity, total flavonoid compounds, and vitamin C. The highest fresh weight of shoot and fruit number were obtained from Nano-nitrogen treatment + 75kg. ha-1 while the highest amounts of vitamin C, Total antioxidant capacity, and total flavonoid compounds were obtained from Azotobacter and Azospirilum inoculated plants. Azotobacter was superior to Azospirilum in most of the traits and with increasing the application of urea fertilizer, it maintained its efficiency compared to the control. The highest fruit yield was obtained from Nano-nitrogen + 75kg. ha-1, but there was no statistically significant difference from Azotobacter + 75kg. ha-1. Therefore, since the aim of the experiment was to increase the yield and quality of the fruit, Azotobacter + 75kg. ha-1 is recommended as compared with the other treatments.
