Abstract

Cover plants, due to their high biomass production capacity, and plants provide the soil with several benefits such as nutrient cycling, greater water retention and storage capacity, reduced temperature, increased aggregation and microbiota, physical protection against compaction. The objective of this work was to verify the growth of the fruit species of the cerrado, Dipteryx alata Vogel, as a consortium strategy with green fertilizers, Arachis pintoi Krapov. & W.C.Greg./Callopogonium mucunoides Desv., Crotalaria juncea L, Dolichos lablab L., [Urochloa decumbens (Stapf) R.D.Webster] with nitrogen and [Urochloa decumbens (Stapf) R.D.Webster] without nitrogen (control). The experiment covered the period from 2013 to 2017, in Rio Verde, Goiás, installed in a randomized block design, with five treatments (cover plants) and four replications. The evaluations included the macro and micronutrient contents in D. alata, biomass production by cover plants, soil moisture and biometric determinations of D. alata. The use of U. decumbens with nitrogen, D. lablab and C. juncea showed better performances in maintaining soil moisture, growth and early fruiting of D. alata, making it advantageous to use these types of consortium in its establishment under conditions of the Cerrado.

Highlights

The Cerrado is a biome with rich biodiversity, accounting for around 11,000 cataloged plant species, many endemic to the region, being recognized as the richest savanna in the world (MMA, 2014)
When observing the confidence interval of parameter A for height, it was found that the cover plants D. lablab and U. decumbens + N, showed higher value than the plant U. decumbens (Table 2)
U. decumbens + N, D. lablab and C. juncea were the treatments that provided the best performance in the development of D. alata

Summary

Introduction

The Cerrado is a biome with rich biodiversity, accounting for around 11,000 cataloged plant species, many endemic to the region, being recognized as the richest savanna in the world (MMA, 2014). In the Cerrado the native fruit plants are evident, being a group that adds up to more than 50 species, even in their natural state, they demonstrate adaptability in agricultural system and representative productivity (Andaló et al, 2018; Soares et al, 2018). The most explored potential of the Cerrado is the fruits, in which is consumed naturally or in the form of juices, liqueurs, jellies and savory dishes (de Andrade Silva & Fonseca, 2016; Donado-Pestana et al, 2018; Franco et al, 2020). The varied shapes, flavors, aromas and colors represent another important characteristic of the Cerrado fruits (Coradin et al, 2011)
