Abstract:
The aim of the experiment was to evaluate the use and influence of Bat guano and Nettle slurry on the growth, flowering and mineral absorption of Delosperma cooperi and Sedum rubrotinctum plants. The 3 experimental groups in cultivation were: (1) group without biostimulants (CTRL), irrigated with water and previously fertilized substrate; (2) group Bat guano (BG) and fertilized substrate; (3) group Nettle slurry (Urtica dioica L.) (UD) and fertilized substrate. Treatments with Nettle slurry and Bat guano resulted in a significant improvement in the growth and flowering characteristics of Delosperma cooperi and Sedum rubrotinctum. The test showed in fact a significant increase in the agronomic parameters analysed in plants treated with Bat guano and Nettle slurry. In fact, all the plants treated with (BG and UD) showed a significant increase in the number of leave, flowers and inflorescences, in the vegetative, radical and inflorescence weight, in the flowering time. The test also resulted in an increase in the NPK mineral absorption and chlorophyll content of plants treated with bat guano and nettle slurry.Interesting aspects that make Bat guano and Nettle slurry valid alternatives to be used as plant biostimulants, when the plants are subjected to biotic and abiotic stresses, in particular transplant, water and salt stress.
