Background:

The current challenge is to produce food in systems that are resilient to climate change and take care of the environment.

Aim.

Evaluate organic and mineral biofertilization in the growth and development of Tithonia diversifolia positions during the nursery phase.

Materials and methods:

Two trials were carried out: E-I at the “Renato Guitar” CPA and E-II: at the Indio Hatuey Pasture and Forage Experimental Station (EEPFIH). For their development, a completely randomized experimental design was used with 15 and 10 replications, experiment I and II respectively. E-I, three treatments were carried out: T-1: 100% unfertilized soil, T-2: 50% soil + 50% biochar, T-3: 50% soil + 25% biochar + 25% cane bagasse ash. The biochar was obtained from marabou (D. cinerea) and was always embedded in efficient IHPLUS®BF microorganisms. Physiological parameters of primary and secondary metabolism were measured at 30 days, and morphological growth indicators at 30 and 60 days. In E-II, 5 treatments were used: T-1: Unfertilized soil, T-2: Combination of 50% soil-50% compost + Rhizobium, T-3: Combination of 50% soil-50% compost + Trichoderma, T-4: Combination of 50% soil-50% compost with micronized dolomite + Rhizobium and T-5: Combination of 50% soil-50% compost with micronized dolomite + Trichoderma. Morphological growth indicators were measured at 60 days and production of dry aerial biomass at the time of transplant.

Results:

the results show that in Trial-I the best variant was T-3: soil 50%+IHPLUS®BF enriched Biochar 25%+ash 25%. Test-II, all the variants studied were superior to the control.

Conclusion:

The results confirmed the effectiveness of these alternatives to grow T. diversifolia plants under nursery conditions.
