Assessment of the Biotechnological Potential of Zoohumus in Dill Growing

This research work presents scientific conclusions on the role of biological fertilizers in ensuring food security based on a sustainable agricultural system, their safety aspects, and the development and significance of non-traditional biological fertilizer biotechnology. The importance of zoohumus prepared on the basis of the Tenebrio molitor mealybug as a non-traditional biological fertilizer in the growth and development of the medicinal and aromatic dill sedge was demonstrated. In assessing the effect of zoohumus on the growth and development of sedge, cattle manure processed on the basis of earthworms, i.e. biohumus, was used as a control. Based on the research, it was shown that zoohumus retains nutrients that are easily absorbed by dills several times higher than biohumus. In particular, it was noted that zoohumus retains 0.77% more total N-NH4 than biohumus. It was also found that the total P2O5 in zoohumus was 6.45% on average, which is 3.49% more than in biohumus. In addition, based on studies, it was noted that the total K2O content of zoohumus was 3.44% on average, which is 3.49% more than in biohumus. It was also shown that the amount of mobile N-NH4 in zoohumus was 362.28 mg/kg, which is 229.81 mg/kg more than in biohumus. The amount of mobile phosphorus (P?O?, mg/kg) was found to be 1150.18 mg/kg than in zoohumus and 294.2 mg/kg more than in biohumus. It was also shown that the amount of mobile potassium (K2O) in zoohumus was 7166.82 mg/kg on average, which is 3061.17 mg/kg more than in biohumus. Also, the effect of zoohumus and biohumus on some biometric indicators and chlorophyll retention properties of Dill grown for 30 days was shown. Based on the results of the study, it was recommended to use zoohumus in agricultural practice as a more stable biological fertilizer than biohumus.
