<b>Agronomic performance and nutritive value of millet silages

Abstract

ABSTRACT. The objective of this study was to assess agronomic characteristics and nutritional values of silages of millet genotypes. Planting was done in randomized blocks, with five replicates per genotype. Green matter yield for genotypes ADR 500 and CMS 01 was higher and similar to each other, with 40.16 and 41.36 t ha (p > 0.05). There was no significant difference for dry matter yield, with the mean being 9.93 t ha (p > 0.05). The silages were similar (p > 0.05) as to pH, Aw and N-NH3/TN, presenting values of 3.92, 0.97 and 7.64%, respectively. There were no significant differences (p > 0.05) concerning the bromatological composition of the silages of the different genotypes, with a mean of 30.74% of dry matter, 10.21% for crude protein and 58.69% for neutral detergent fiber (p > 0.05). The dry matter digestibility mean stood at 59.90%. Based on the nutritional values and digestibility of the millet silages, the five genotypes are suitable for silage production, with potential for the North of Minas Gerais.Keywords: digestibility, dry matter yield, silage.Desempenho agronômico e valor nutritivo das silagens de milheto RESUMO. Objetivou-se com este trabalho avaliar as características agronômicas e o valor nutricional das silagens de genótipos de milheto. O plantio foi realizado em blocos casualizados, com cinco repetições por genótipo. A produção de matéria verde para os genótipos ADR 500 e CMS 01 foram superiores e semelhantes entre si, com 40,16 e 41,36 t ha (p > 0,05). Não houve diferença significativa para a produção de matéria seca, e a média foi de 9,93 t ha (p > 0,05). As silagens mostraram-se semelhantes (p > 0,05) em relação ao pH, Aw e N-NH3/NT, apresentando valores de 3,92; 0,97 e 7,64%, respectivamente. Não foram encontradas diferenças significativas (p > 0,05) em relação à composição bromatológica das silagens dos diferentes genótipos, sendo observados médios de 30,74% de matéria seca; 10,21% para proteína bruta; 58,69% para fibra em detergente neutro e (p > 0,05). A média da digestibilidade da matéria seca foi de 59,90%. Com base no valor nutricional e na digestibilidade das silagens de milheto, os cinco genótipos apresentam-se adequados à produção de silagem com potencial para o norte de Minas Gerais Palavras-chave: digestibilidade, produção de matéria seca, silagem.

Pearl millet cultivation with brackish water and organic fertilizer alters soil properties

“…Among the diversity of forage available to feed herds in semi-arid regions, Pearl millet (Pennisetum glaucum) has good yield and nutritional quality, short cycle and regrowth capacity (17,18) in addition to tolerance to saline stress (19,20) , characteristics that make pearl millet a sustainable alternative for cultivation in biosaline systems.…”

Production of Pearl Millet Irrigated with Different Levels of Brackish Water and Organic Matter

“…One of the techniques used for cultivation of plants in saline environments is the use of resistant and adapted species, such as pearl millet, highlighting its ability to adapt to saline environments and semi-arid conditions. Pearl millet has high biomass productivity, agronomic and nutritional characteristics necessary for use as forage, has adequate nutritional quality for the production of hay, silage and fresh consumption (Moura et al 2018).…”
