Objetivou-se, com este trabalho, ajustar modelos de regressão não linear ao crescimento quatro variedades capim-elefante e duas cana-de-açúcar, cultivadas em neossolo irrigado cotejamento, na região do Vale Submédio São Francisco, sob condições baixa tecnologia, no período março a julho 2023, avaliar o desempenho morfológico produtivo dessas culturas. O delineamento experimental foi blocos casualizados (DBC) seis tratamentos blocos. Confeccionaram-se 24 sulcos metros comprimento, espaçados 1...
Este trabalho teve como objetivo avaliar as características morfológicas e produtivas de quatro variedades capim-elefante duas cana-de-açúcar cultivadas em neossolo irrigado por gotejamento na região do Vale Submédio São Francisco, sob condições baixa tecnologia. O delineamento experimental foi blocos casualizados (DBC), com seis tratamentos blocos. Foram confeccionados 24 sulcos metros comprimento, espaçados 1 metro. As parcelas experimentais consistiram linhas 4 comprimento cada....
Abstract Elephant grass [ Cenchrus purpureus (Schum.) Morrone] is a tropical forage widely used in ruminant feeding and subtropical areas, mainly cut-and-carry systems due to high potential for herbage accumulation. However, most common genotypes (tall genotypes) generally show an early stem elongation, which contributes rapid decline the nutritive value. Dwarf elephant types usually present less elongation may be considered option production of value systems. The aims this study were...
The objective of this review was to describe the main factors that influence production dairy cows submitted grazing and importance evaluation milk plasma urea nitrogen for animal performance. Pastures are fundamental in Brazilian cattle raising, guaranteeing low costs since it is most economical practical way produce offer food herd. However, despite great diversity grasses with high-quality forage potential, several regions Brazil present productivity. In recent years, due advances genetic...
Abstract This study aimed to evaluate the impact of two harvest frequencies (60 and 90 days) on morphogenic structural characteristics four Elephantgrass genotypes (two tall dwarf) in both rainy dry seasons. The research was conducted Garanhuns, Brazil from September 2019 December 2021. evaluated included leaf appearance rate, stem elongation phyllochron, plant height, diameter, length, basal tiller population density, number leaves per tiller. results showed that Elephant B had highest rate...
The objective was to evaluate the growth and hay production of Mimosa tenuiflora (Willd.) Poir. submitted regrowth control in caatinga areas Brazilian semiarid region. An experimental area 4.0 ha used, divided into four paddocks 01 ha. silvopastoral management techniques consisted lowering thinning woody species. treatments three levels regrowth: plants lowered managed allow one (01) regrowth; two (02) (03) a Witness, which allowed all regrowth. In each plot, ten were randomly selected. A...
