The Effect of Chemical and Biofertilizer on Grain Yield of Two Dill (Anethum graveolens L.) Cultivars

To study the effect of the combined fertilizer management of bio-fertilizer and chemical fertilizers on the grain yield of two dill (Anethum graveolens L.) ecotypes, a field experiment was arranged in a factorial layout based on randomized complete block design with three replications in 2019 in Agricultural Research Farm of the University of Tabriz. The first factor includes two ecotypes (C1: Native of Tabriz and C2: Varamin), while the second factor was composed of five fertilizers levels, namely, control (N0), chemical fertilizers (N1), Enterobacter cloacae S16-3 bacteria + half a chemical fertilizer (N2), Piriformospora indica Fungi + half a chemical fertilizer (N3) and the combination of bacteria + fungi + half a chemical fertilizer (N4). Although the highest yield and yield components were obtained for chemical fertilizer treatment (N1), there was no statistically significant difference with the combined treatment (N4). The combined application of biofertilizers (growth-promoting bacteria and fungi), in addition to reducing chemical fertilizers (50%), led to a high grain yield. Accordingly, the application of combined treatment (N4) can be a suitable treatment for the cultivation of medicinal plants, including dill.
