Abstract
To improve the quantity and quality of dry matter produced from a feed mixture by using a combination of humic acid (H) kg ha-1, kinetin (K) mg liter-1, and nitrogen fertilizer (N) kg ha-1 (H:K:N) (0:0). :0, 24:0:0, 0:30:120, 24:15:60, 16:15:60, and 0:0:120) with different seeding rates of Triticale (W) and Egyptian clover (C) (C: W( (0:120, 32:0, 16:120, 32:60, and 16:60) A field experiment was planted at the research station of the Field Crops Department at Tikrit University in the fall season of 2022 using a Completely Randomized Block Design and a split-plot system (main panels: Combinations of chemicals and secondary panels: seeding rates). The results showed that the 16:15:60 (H:K:N) treatment had the highest rate of green yield and percentage of dry matter and protein. Similarly, the seed rate mixture of 16:120 (C:W) excelled in the green yield in the first and second mowing and the dry matter yield in the first and second mowing, while the seed rate mixture of 32:0 (C:W) excelled in the percentage of protein in the three mowing. The seed rate mixture 16:120 (C:W) was superior in protein yield in the first and second mowing (0.332 and 0.342 tons ha-1, respectively) and the seed rate mixture 16:120 (C:W) in the third mowing was superior in yield. Protein yield reached 0.206 tons ha-1. The interaction among the combinations of chemicals and the combinations of seed rates had a significant effect on the experiment results, as the interaction 16:15:60 (H:K:N) + 16:120 (C:W) was significantly higher in green yield and percentage of dry matter. The protein yield is in the first mowing while the interaction 0:30:120 (H:K:N) + 0:120 (C:W) and the interaction 16:15:60 (H:K:N) + 0:120 (C: W) and the interaction 0:30:120 (H:K:N) + 0:120 (C:W) indicated the highest green yield in the first and second mowing, the percentage of dry matter in the three mowing, the dry matter yield in the first mowing, and the protein yield in the third mowing. The results of this study enhance knowledge of feed mixtures and the possibility of using them in agricultural production.
