El área de cultivo de alfalfa en América Latina es muy heterogénea, desde los 3,2 millones de hectáreas que Argentina cultiva actualmente hasta las 35.000 hectáreas en Brasil. Las formas de utilización son variadas y van desde el uso exclusivo bajo corte para la producción de heno o para pastoreo mecánico hasta el uso en pastoreo directo para la pr...
La alfalfa se considera uno de los forrajes más importantes por reunir características importantes como productividad, calidad proteica, aceptabilidad, digestibilidad, capacidad de fijar el nitrógeno atmosférico y baja estacionalidad de la producción de forraje. Sin embargo, es un cultivo exigente en manejo y su expansión en América Latina depende ...
The selection of native forage species with yield potential under climate change scenarios can strengthen resilience of the Brazilian semiarid region. This study aimed to evaluate the effect of increasing temperature on growth and morphological and yield responses of plants of the genus Manihot. The experimental design was completely randomized in ...
ABSTRACT - Sorghum is a crop of great interest in animal feed in semiarid regions. The environment and nitrogen fertilization can influence its productive potential and nutritional quality. This study aimed to evaluate sorghum biomass genotypes associated or not with Azospirillum brasilense managed at different sowing sites on the yield and nutriti...
Integrated systems (crops, livestock, and forest) are tools to avoid increases in greenhouse gas (GHG) emissions, such as CO2, CH4, and N2O. The objective of this study was to evaluate the GHG emissions and soil biological and chemical characteristics in an integrated system. The experiment was carried out in an area with crop-livestock-forest inte...
The objective was to evaluate the effect of different irrigation systems and harvest frequencies on the cultivation of cactus pear. The study was conducted in the semi-arid region, in the municipality of Russas, CE, Brazil. The experiment was a split plot randomized block design, with four replications. Plots were represented by irrigation systems ...
In dry regions worldwide, providing feed for ruminants has been a great challenge, with a need to use plants which contribute to the resilience of production systems. Maniçoba is seen as a potential forage resource in the Brazilian semiarid, being used as hay or silage to feed ruminants. This review summarized results regarding forage production of...
Traditional procedures for biomass estimation usually use destructive methods with great demands on time, resources, and labor. The development of models for automated estimation of pasture biomass, particularly from images captured by Unmanned Aerial Vehicle (UAV), in addition to high spatiotemporal resolution combined with flexibility in image ac...
No Nordeste brasileiro, as práticas agropecuárias tradicionais seguem o modelo migratório, que inclui o desmatamento total, a queimada da madeira, a agricultura extrativista, o superpastejo, o regime de criação predominantemente extensivo e o baixo ou nenhum uso de insumos, culminando no processo de degradação dos solos. Com isso, observa-se a nece...
