Structural and productive features of Panicum cultivars submitted to different rest periods in the irrigated semiarid region of Brazil

Bioscience Journal, 2019
The objective of this study was to evaluate the structural and productive features of Panicum maximum cultivars (Tanzânia, Mombaça, Massai, and Zuri) in three rest periods (30, 45 and 60 days), in the semiarid region of Brazil. The experiment was carried

Breeding Efficiency for Salt Tolerance in Alfalfa

Life, 2023
Alfalfa (Medicago sativa L.), one of the most extensively grown forage crops, is sensitive to saline soils. We measured the breeding efficiency for increased salt tolerance in alfalfa by comparing lines selected from BC79S, CS, and SII populations with ...

Does the residual effect of n-fertilization applied on corn phase maintain forage production of the following pasture phase in an integrated crop-livestock system?

Bioscience Journal, 2020
Nutrient cycling represents an important nutrient source in the Integrated Crop-Livestock Systems (ICLS). In general, only the crop phase of the ICLS is fertilized, however little is known about this residual effect of nitrogen fertilization from summer ...

Photosynthetic Physiological Basis of Forage Mass Stability in a Progeny of Rhizome-Rooted ‘Qingshui’ Medicago sativa L.

Agronomy, 2023
Rhizome-rooted alfalfa (Medicago sativa L.) is an excellent forage for establishing grazing and ecological grasslands, requiring a high and stable yield. Studying the genetic and physiological basis of stable expression of biomass traits is essential for

Forage potential of S3 corn progenies in topcrosses and selection of testers of different genetic bases [PDF]

Pesquisa Agropecuária Brasileira, 2020
: The objective of this work was to identify corn (Zea mays) genotypes with forage potential and to evaluate the efficiency of testers to discriminate forage traits in topcrosses, considering the contribution of additive and nonadditive genes.

Breeding limits foraging time: evidence of interrupted foraging response from body mass variation in a tropical environment [PDF]

Journal of Avian Biology, 2017
Birds should store body reserves if starvation risk is anticipated; this is known as an ‘interrupted foraging response’. If foraging remains unrestricted, however, body mass should remain low to limit the predation risk that gaining and carrying body reserves entails.

Methodologies in the evaluation of forage mass in tree legumes

Revista Brasileira de Ciências Agrárias - Brazilian Journal of Agricultural Sciences, 2018
To choose the method of forage mass estimation (FM), consider the plant species, required accuracy and available technology. In this sense, the objective was to evaluate the methods of determination of direct FM and comparative visual per­formance with five and 10 patterns, in the trees Gliricidia (Gliricidia sepium Jacq.) and Sabia (Mimosa ...

Forage intake processes by goats on a massai grass pasture with different sward heights

Semina: Ciências Agrárias, 2016
The objective of this study was to evaluate the forage-intake process of goats feeding on Massai grass pastures with different heights (40, 50, 60, and 70 cm). The experimental design was completely randomized, with treatments corresponding to four sward
