Movement ecology of exotic nilgai antelope: A threat to the re‐emergence of cattle fever ticks in the southern USA

Ecosphere, Volume 14, Issue 2, February 2023., 2023
Abstract Wildlife plays an important role in the emergence of livestock diseases, and their movements can complicate disease management efforts. One of the most significant vector‐borne diseases of livestock worldwide is bovine babesiosis, spread by cattle fever ticks (CFTs; Rhipicephalus [=Boophilus] microplus and Rhipicephalus [=Boophilus] annulatus).

Forage conservation in sub‐Saharan Africa: Review of experiences, challenges, and opportunities

Agronomy Journal, Volume 114, Issue 1, Page 75-99, January/February 2022., 2022
Abstract Forage conservation is an important potential solution to seasonal variation in feed quality and quantity and herder‐farmer conflicts in sub‐Saharan Africa (SSA). Considerable variations exist in the type of forages conserved and the preservation methods across SSA. Hay from cultivated forages is commonly made with mechanical mowers and balers

Gender dynamics around introduction of improved forages in Kenya and Ethiopia

Agronomy Journal, Volume 114, Issue 1, Page 277-295, January/February 2022., 2022
Abstract Improved forages of genus Brachiaria and Panicum grasses were introduced to men and women farmers in western Kenya and southern Ethiopia. To provide an understanding of the social and demographic characteristics of farming systems, a household survey was implemented in 2018/2019.

Maize and sorghum root growth and yield when intercropped with forage grasses

Agronomy Journal, Volume 113, Issue 6, Page 4900-4915, November/December 2021., 2021
Abstract Integrated crop–livestock systems that intercrop forage crops with grain crops are effective for increasing forage production and improving nutrient cycling and soil health. However, the potential for root competition when maize (Zea mays L.) and sorghum [Sorghum bicolor (L.) Moench] are intercropped with forages in sandy soils is unknown. The

Guiding fall fertilization of cool‐season turfgrass lawns with verdure tissue‐N tests

Crop Science, Volume 61, Issue 3, Page 2090-2112, May 2021., 2021
Abstract Objective tests are not widely used to guide fall N fertilization of turfgrasses, and N is applied at predetermined rates regardless of plant‐N status. This study was conducted across 3 yr in Connecticut to determine if fall verdure concentrations of total N, dry‐tissue extractable nitrate (NO3)–N, and fresh sap NO3–N could guide fall N ...

Introduction of forage legumes into Aruana Guineagrass pasture

Boletim de Indústria Animal, 2020
The experiment was developed at the Instituto de Zootecnia in Nova Odessa-SP. It was designed to evaluate forage mass, forage legumes ratio in the available forage mass and the transfer potential of the nitrogen fixed by the forage legumes to Aruana Guineagrass pasture grazed by lambs under intermittent grazing.

Estimativa da área foliar de Panicum maximum usando dimensões lineares do limbo foliar Leaf area estimate in Panicum maximum weeds, using leaf blade linear dimension

Planta Daninha, 2001
Com o objetivo de obter uma equação que, por meio de parâmetros lineares dimensionais das folhas, permitisse a estimativa da área foliar de Panicum maximum, estudaram-se relações entre a área foliar real (Sf) e os parâmetros dimensionais do limbo foliar,

Adaptation of the C4 grass Panicum maximum to defoliation is related to plasticity of N uptake, mobilisation and allocation patterns

Scientia Agricola, 2012
Dry mass production and persistence of Panicum maximum pastures depends on nitrogen supply. Defoliation influences N uptake and allocation patterns yet its effects on plasticity of N dynamics in P. maximum have not been investigated. Stable isotopes of N

Using near infrared reflectance spectroscopy for estimating nutritional quality of Brachiaria humidicola in breeding selections

Agrosystems, Geosciences &Environment, Volume 3, Issue 1, 2020., 2020
Abstract Brachiaria humidicola (BH) (syn. Urochloa humidicola) is an important forage grass in the tropics due to its capacity to grow in nutrient‐deficient soils, tolerate waterlogging, and inhibit soil nitrification. A major objective of BH breeding is to improve its nutritional quality. Therefore, a rapid and low‐cost method is needed to assess main
