Effect of humic+fulvic acid and micro element applications on mineral nutrition and yield of triticale

This study aimed to investigate the effects of humic + fulvic acid (HFA) and micro element (ME) applications on triticale yield and mineral nutrition. Therefore, in the trial carried out in Başmakçı District of Afyonkarahisar Province in the 2022-2023 production season, mixtures consisting of HFA doses of 5 and 10 liters per decare and iron (Fe), copper (Cu), zinc (Zn), manganese (Mn) and boron (B) doses of 1, 0.25, 0.5, 2 and 0.15 kg (ME1) and 2, 0.5, 1, 4 and 0.3 kg (ME2), respectively, were applied to the soil. The trial was carried out in a randomized block design under field conditions with 4 replications according to divided plots. It was observed that HFA and ME applications applied at increasing doses were effective on grain yield, plant height, spike length, number of spikelets per spike, number of grains per spike, grain weight per spike, thousand grain weight and Fe, Cu, Zn, Mn, B, N, P and K contents of triticale, while it had no effect on Ca and Mg contents. The highest grain yield of 1352 kg per decare was obtained from mixtures of 10 l HFA and 2, 0.5, 1, 4 and 0.3 kg/da Fe, Cu, Zn, Mn and B, respectively. When the individual effects of the applications were examined, the high dose of HFA was the most effective dose, while the yield obtained per decare with this application increased from 820 kg to 1219 kg. It was determined that the yield increased depending on the increasing doses in ME applications, and it was determined that the grain yield, which was 971 kg in the control, increased to 1128 kg with ME application. Similarly, other yield parameters were also positively affected by ME applications. When the plant analysis results related to the micro element nutrition of the plant were examined, it was shown that ME applications, except B, mostly had no significant effect on the micro element nutrition of the plant. ME applications did not affect the N, Ca and Mg contents of the plant, while they increased the K and P contents. If a general evaluation is made according to the obtained results, it was seen that the most effective application on the grain yield of the plant was HFA2+ME2, but a yield in the same group was obtained from the HFA2+ME1 application statistically. Accordingly, it is recommended to prefer the most economically suitable one among the two applications.
