Introduction: Adopting a new path in agricultural practices requires reducing the pressure on the environment and human health. In order to maintain productivity and reduce the input of agricultural chemicals the use of useful plant microbes such as arbuscular mycorrhizal fungi and plant growth enhancing rhizobacteria have a high potential. This experiment was carried out with the aim of increasing yield and helping to better manage wheat weeds by combining chemical methods and using biofertilizers.
Materials and methods: This study was conducted in order to investigate the effect of biological fertilizers and weed management on wheat yield and yield components in the form of randomized complete block design in 20 treatments and 3 replications at Gonbad Kavous Agricultural Research Station in the 2018-2019. The first factor included phosphonitro biofertilizer, bioazospire biofertilizer, phosphozist biofertilizer, bionutrient biofertilizer (combination of minerals and microorganisms), and control (no use of seed fertilizer). The second factor was chemical fertilizer in two levels of using and not using chemical fertilizers and the third factor was herbicide in two levels of using and not using Othello herbicide (iodosulfuron methyl + mesosulfuron methyl + diflufenican + mefene pyrdiethyl). In this plan wheat cultivar N92-19 was used and cultivated based on the density of 180 kg per hectare. Dry weight of weeds and wheat traits including spike length number of spikes per plant number of seeds per spike weight of 1000 seeds seed yield and harvest index were done using fixed squares of one by one meter.
Results: The simple effect of seed fertilizer and herbicide treatments on plant height spike length number of spikes per plant and dry weight of wheat was significant; And the interaction effect of seed and fertilizer treatment on the two attributes of spike length and dry weight of wheat the interaction effect of fertilizer and herbicide treatment on dry weight and the triple interaction effect of all treatments on the number of spikes in the plant were significant. In total the highest amount of yield is related to the treatment of phosphonitro biofertilizer with the use of fertilizer and herbicide and the lowest amount is related to the treatment of azospire biofertilizer without the use of fertilizer and herbicide. The treatments of phosphonitro and then phosphozist had better performance in comparison with other biofertilizers.
Conclusion: In total the highest yield is related to the treatment of phosphonitro biofertilizer with the use of fertilizer and herbicide and the lowest yield is related to the treatment of azospire biofertilizer without the use of fertilizer and herbicide. The treatments of phosphonitro and then phosphozist had better performance in comparison with other biofertilizers it can be concluded that the rooting in the plants treated with the two aforementioned biofertilizers is significantly enhanced in the presence of phosphorus and ultimately interacts with chemical fertilizers and herbicides. They have shown acceptable performance. Also based on the results of this research the combined use of biological and chemical fertilizers causes better performance than the separate use of each of the mentioned fertilizers. |
