CULTIVO DE Crotalaria spectabilis, Cajanus cajan E Pennisetum glaucum EM SOLOS DE CERRADO: CARACTERÍSTICAS FÍSICO-QUÍMICAS DO SOLO E COMPOSIÇÃO BROMATOLÓGICA DAS CULTIVARES

Abstract

The aim was to describe the physico-chemical characteristics of the soil and the bromatological composition, as an alternative for the recovery of Cerrado soils and animal feed supply. The experiment was conducted at the Unit Experimental Production ZOOIII the Instituto Federal Goiano - Campus Urutaí in the city of Urutaí/GO. They were established with four treatments (two pulses - Crotalária, Crotalaria spectabilis and Feijão-Guandú, Cajanus cajan, a grass - Milheto, Pennisetum glaucum and control - Brachiaria (Brachiaria decumbens) were carried out analysis of the physical and chemical properties of soil above cultivation and with a year of cultivation. For bromatological composition analysis, was carried samples with 120 days of cultivation, considerate out first cut and with 160 days the second cut, considerate out second cut. The Crotalária, Feijão-Guandú e Milheto were not able to change the physico-chemical characteristics Cerrado soils within the study period. After the analysis, it was observed higher rates of Crotalária compared to other species as the characteristics of the chemical composition.
