?Rotatinuous? stocking is a grazing management strategy based on animal behavioural responses to sward structure which is designed to maximize herbage intake per unit of grazing time. It is an alternative to traditional grazing management practices focusing on pasture use efficiency and maximizing herbage accumulation and harvesting. To investigate this approach, Italian ryegrass (Lolium multiflorum) pastures grazed by sheep were evaluated in 2014 and 2015 under two contrasting grazing management strategies.

Resumen: Se evaluó el efecto de suplementar con ensilado de grano húmedo de maíz o un concentrado comercial sobre el consumo y producción de vacas lecheras. Cuarenta vacas pastoreando una pradera sembrada fueron asignadas a los siguientes tratamientos según un diseño de bloques completos al azar durante 9 semanas:sin suplementación, suplementación con 3 o 6 kg de materia fresca de ensilado de grano húmedo de maíz, suplementación con 3 o 6 kg de materia fresca de un concentrado comercial.

Abstract:Background and aims:The concepts of critical nitrogen (N) concentration and nitrogen nutrition index (NNI) provide effective tools for assessing the N nutritional status of pastoral systems. However, no conclusive data exist concerning the effects of stubble height at harvest on the Ndilution curve [N concentration (N%) = a(biomass)?b] and mixed species cultivation on N nutritional status of forage plants with contrasting growth strategies.

ABSTRACT. Soybean crop productivity is limited by several biotic factors, particularly plant-parasitic nematodes. Several species have been reported to cause crop damage, especially those of the genus Meloidogyne. Therefore, the aim of this study was to evaluate, the reaction of 28 soybean genotypes to Meloidogyne arenaria and M. morocciensis in a greenhouse. The soybean genotypes were the same for experiments with different species of plant-parasitic nematodes and were individually inoculated with 5,000 eggs + second-stage juveniles (J2) of Meloidogyne and kept in a greenhouse.

Simple Summary: Interest in selection for milk yield and thermotolerance in cattle has grown, since heat stress has caused great losses in milk yield. However, few studies on how to carry out concurrent selection are available. Milk yield was analyzed by traditional methods, including heat stress indicators, in genetic evaluation. The results showed that the best sires for milk yield are not the best for heat tolerance, and only a small proportion of individuals have the aptitude for joint selection.

ABSTRACT. Citrus fruit are sensitive to chilling injury (CI) during cold storage, a peel disorder that causes economic losses. C-repeat binding factors (CBFs) are related to cold acclimation and tolerance in different plants. To explore the role of Citrus CBFs in fruit response to cold, an in silico study was performed, revealing three genes (CBF1, CBF2, and CBF3) whose expression in CI sensitive and tolerant cultivars was followed. Major changes occurred at the early stages of cold exposure (1?5 d).

Abstract- CONTEXT:Successful scaling up from crop level research to adoption by farmers depends on its practitioners being aware of the constraints that arise as scaling up proceeds. Promising ideas from crop level research are not adopted by farmers in many cases. OBJECTIVE:Scaling up is explored here in a study conducted in five vegetable farms in south Uruguay, where tomato production was one of the main sources of income.
