Interrelationship of nitrogen fixation potential and Soybean yield
Institute of Field and Vegetable Crops, Novi Sad
Keywords: soybean; genotype; nitrogen fixation potential; NS-Nitragin; yield
Abstract
Studied in this paper was the nitrogen fixation potential of eight different soybean genotypes belonging to different Maturity Groups (Afrodita, Bačka, Concil, Balkan, Trail, Nizija, Vojvođanka and Glacijer). The objective was to determine whether or not there is a correlation between the indicators of the symbiotic association effectiveness and soybean grain yields. To that end, a trial was established in 2000 at the Rimski Šančevi Experiment Field of the Institute of Field and Vegetable Crops in Novi Sad. A randomized block design with three replicates was used. Sowing was done on optimum dates and the microbiological preparation NS-Nitragin was applied. The highest grain yields were produced by the cultivars Afrodita and Balkan. These cultivars also had high values of the nitrogen fixation indicators plant dry matter mass and the nitrogen levels in the above-ground plant parts and nodules. The cultivars Bačka and Nizija had the smallest grain yield as well as the smallest nodule mass and nodule nitrogen content. The cultivars Concil, Trail and Glacijer, originating from the U.S., had a somewhat lower grain yield than Afrodita, which may be due to the fact that they have not adapted to the conditions in this part of the world. The highest nitrogen fixation potential was found in Afrodita and Balkan and the lowest in Bačka and Nizija.
