Effects of Nitrogen Fertilization on Weed Flora and Productivity of Soybean [Glycine max (L.) Merr.] Crop

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