Effects of Nitrogen Fertilization on Weed Flora and Productivity of Soybean [<i>Glycine max</i> (L.) Merr.] Crop
The literature suggests that nitrogen (N) fertilization increases yield in soybean. This study aimed to investigate the effects of N fertilization on: (i) The performance of soybean, and (ii) the weed flora. A two-year field experiment was carried out in Agrinio, Western Greece.

| description | The literature suggests that nitrogen (N) fertilization increases yield in soybean. This study aimed to investigate the effects of N fertilization on: (i) The performance of soybean, and (ii) the weed flora. A two-year field experiment was carried out in Agrinio, Western Greece. The experiment was set up in a randomized complete block design, with four organic fertilizer treatments and six replications. The four treatments included 0 kg N ha<sup>−1</sup> (N0/unfertilized control) and the application of 80 kg N ha<sup>−1</sup>, 100 kg N ha<sup>−1</sup>, and 120 kg N ha<sup>−1</sup>. The application of 120 N kg ha<sup>−1</sup> resulted in the most notable increment of plant height (22.6–24%), biomass (10–13%), LAI values (14–17%), and yield (10–12%) compared to the N0. Compared to the N0, total weed biomass was increased by 26–32%, 34–49%, and 55–57% in N80, N100, and N120, respectively. The values of the H (Shannon), Dmg (Margalef), and J (Pielou) indices were unaffected by the fertilization, hence they did not affect weed biodiversity. CRI (crop resistance index), on the contrary, was negatively affected by N fertilization and was significantly reduced. Overall, our results indicate that the application of 80 kg N ha<sup>−1</sup> is more efficient, can effectively improve the soybean performance, and enhance its yield. |
