Organic fertilization strategies and use of Trichoderma in the agronomic performance of green maize.

Abstract

There is scientific evidence that Trichoderma positively influences the uptake of soil nutrients by plants, which is essential for the development of more efficient organic fertilization strategies in green maize. Therefore, the objective was to evaluate the efficiency of applying Trichoderma with organic fertilization strategies on the growth and productivity of green . The experiment was conducted at the Piroás Experimental Farm, belonging to the Universidade da Integração Internacional da Lusofonia Afro-Brasileira (UNILAB), located in the municipality of Redenção, Ceará. A randomized complete block design was used with six treatments (T1 - control; T2 - 50% of the cattle manure dose + green manure; T3 - 100% of the cattle manure dose; T4 - Trichoderma + 50% of the cattle manure dose + green manure; T5 - Trichoderma + 25% of the cattle manure dose + green manure; T6 - Trichoderma) and four replications. The combination of Trichoderma with a 50% reduction in the cattle manure dose plus green manure had a positive effect on plant growth, especially in total plant dry mass, when compared to the isolated use of the microorganism. This same combination provided a yield similar to the treatment with the maximum dose of cattle manure. The use of Trichoderma in green maize production was effective in reducing the cattle manure dose by up to 50%, impacting vegetative growth and green maize production when combined with green manure.
