Conventional and chlorophyll meter–based nitrogen fertilization management for sweetpotato in the tropics

Crop, Forage &Turfgrass Management, Volume 12, Issue 2, December 2026.
Abstract Sweetpotato [Ipomoea batatas (L.) Lam.] exhibits low nitrogen (N) uptake during early growth stages, suggesting that N fertilization at planting may be unnecessary. A portable chlorophyll meter can be a useful tool for more precise determination of the timing and rate of topdressed N applications, thereby aligning fertilization with crop ...

Does amount of cut vegetal residue on the canopy influence growth and the structural characteristics of marandu palisadegrass?

Bioscience Journal, 2022
The pasture mowing in late winter removes the old forage, improving the pasture structure in spring and summer. However, the residue after mowing can affect tillering, thus limiting forage production and the structural characteristics of pasture.

Impact of Reactive Temperament on Bull Fertility in Natural Service

Reproduction in Domestic Animals, Volume 61, Issue 11, November 2026.
ABSTRACT The study aimed to evaluate the influence of temperament on semen quality and fertility in Nelore bulls. Two groups were selected based on ethological analysis, consisting of animals with either calm temperament (CA, n = 8) or reactive temperament (RE, n = 8).

Growth and senescence of Urochloa brizantha under Brazilian Cerrado conditions

African Journal of Agricultural Research, 2017
The growth and senescence of Urochloa brizantha cv. Marandu were analyzed under the Brazilian Cerrado conditions. The seeds were sowed in November at the beginning of the rainy season. Samples of tillers were collected. The culms, inflorescences, along with green and dead leaves were removed to obtain leaf area and dry matter measurements.

Weighted Single‐Step GWAS Reveals Genetic Mechanisms Underlying Pregnancy Loss in Early Nellore Heifers

Animal Genetics, Volume 57, Issue 5, October 2026.
ABSTRACT Pregnancy loss (PL) affects reproductive efficiency in beef cattle, yet its genetic architecture remains poorly understood in Bos indicus populations. Here, PL was defined as failure from pregnancy diagnosis to calving, capturing a window approximately 60 days after the breeding season.

Effect of Contrasting Tropical Grazing System Intensification on the Performance of Holstein and Jersey‐Holstein Crossbred (Kiwi Cross) Dairy Cows

New Zealand Journal of Agricultural Research, Volume 69, Issue 5, October 2026.
Milk production in Brazil relies on pasture, and intensifying production systems help reduce land use, leading to reduced deforestation and environmental impact. The hypothesis that Jersey crossbred cattle are particularly well suited to grazing systems is also important for Brazilian livestock sustainability.
