Genetic Parameters of Resilience Indicators Across Growth in Beef Heifers and Their Associations With Weight, Reproduction, Calf Performance and Pre‐Weaning Survival

Journal of Animal Breeding and Genetics, Volume 143, Issue 1, Page 79-91, January 2026.
ABSTRACT In tropical extensive beef cattle systems, heifers raised on pasture are exposed to various environmental challenges that affect their growth and reproductive performance during the first breeding. Resilience indicators derived from deviations in longitudinal traits can quantify the magnitude of these challenges and the ability of an animal to

Inoculation and Co‐Inoculation With Plant Growth–Promoting Bacteria in Chickpea: Physiological Aspects and Plant Growth

International Journal of Agronomy, Volume 2026, Issue 1, 2026.
The inoculation of plants with growth‐promoting and nitrogen‐fixing bacteria is considered an effective alternative to reduce the use of nitrogen fertilizers and promote plant growth. This study aimed to evaluate the effect of inoculation and co‐inoculation with growth‐promoting bacteria on the physiological traits and growth of chickpea plants.

Marandu palisade grass intercropped with densely spaced teak in silvopastoral system

Semina: Ciências Agrárias, 2017
This study was conducted to evaluate two systems of production: integration between teak and forage (silvopastoral system) and forage only (monoculture). The forage species used was Marandu palisade grass (Urochloa brizantha cv. Marandu). In January 2009,

Soil Phosphorus Fractions: Effects of Silicate Amendments and Phosphorus Sources in Brazilian Tropical Soils

Journal of Sustainable Agriculture and Environment, Volume 4, Issue 4, December 2025.
ABSTRACT This study evaluated the effects of alternative phosphorus (P) sources and soil pH amendments on P fractions and soil chemical properties in two contrasting Brazilian tropical soils. A greenhouse experiment was conducted using a sandy Arenosol and a clayey Ferralsol treated with triple superphosphate (TSP), reactive phosphate (RP), or ...

Integrated triple cropping enhances soybean productivity

Crop Science, Volume 65, Issue 5, September/October 2025.
Abstract Using soil cover residues from previous crops through integrated systems has proven effective in driving changes in soil properties with nutrient cycling, promoting higher grain production. However, there is still a need to investigate the changes that different cultivation arrangements of these management systems can influence on soybean ...
