Aim: The present work investigated the efficacy of native biocontrol candidates (antagonists) against aflatoxins, ochratoxin A, and fumonisins produced by native mycotoxigenic fungi isolated from Malaysia at different pathogen: antagonist inoculum ratios on grain corn agar and grain corn kernels.
Methods And Results: Five pathogen: antagonist inoculum ratios (100:0, 75:25, 50:50, 25:75, 0:100) were employed. Non-aflatoxigenic Aspergillus flavus Af1KD and Af5TD, and Penicillium janthinellum were used against aflatoxin B1 (AFB1) and aflatoxin B2 (AFB2) by A. flavus. Against ochratoxin A (OTA) by A. niger, and fumonisin B1 (FB1) and fumonisin B2 (FB2) by Fusarium verticillioides and F. proliferatum, respectively, the antagonists Trichoderma asperelloides, T. asperellum, and T. harzianum were used. Non-aflatoxigenic A. flavus Af1KD was the most effective against AFB1 and AFB2 at all tested ratios and substrates. All Trichoderma spp. were effective against OTA by A. niger on grain corn agar at all tested ratios. T. asperelloides and T. asperellum were effective against FB1 and FB2 produced by F. verticillioides at all tested ratios and substrates. T. asperelloides was effective against FB1 and FB2 by F. proliferatum at all tested ratios and substrates.
Conclusion: The native biocontrol candidates were effective against mycotoxigenic fungi and mycotoxin production on grain corn agar and grain corn kernels, and could be developed into biocontrol agents.

Whole pulse ingredient inclusion in macronutrient-balanced diets increased fecal concentrations of propionic acid but not total bile acids in healthy adult large-breed dogs after 20 weeks.

This study investigated the effects of up to 45% inclusion of whole pulse ingredients in grain-free (GF) diets on the excretion of bile acids (BA) and other fecal metabolites in healthy large-breed dogs. Twenty-eight adult Siberian Huskies were fed one of four experimental diets formulated to meet the same macronutrient profiles for 20 weeks: 1) grain-inclusive diet with 45% corn (Ctl), 2) GF diet with 15% pulses (Pulse15), 3) GF diet with 30% pulses (Pulse30), 4) GF diet with 45% pulses (Pulse45). All diets included chicken meal and pea starch.

In order to explore the suitable diversified planting modes in the Yellow River irrigation area of Ningxia, a total of 4 treatments were designed, including wheat-maize silage intercropping and multiple planting of sorghum-sudangrass hybrid after wheat harvest (T1); wheat-cabbage intercropping, multiple planting of oil sunflower after wheat harvest, followed by maize silage planting after cabbage harvest (T2); sole wheat, after the harvest of wheat, half of the land is used for multiple plantings of maize silage, and the other half is used for multiple plantings of oil sunflower (T3); and sole maize silage (T4). The results showed that all diversified planting modes can increase biomass and land equivalent ratio compared to the control monoculture.

Selecting low-nitrogen(N)-tolerant maize hybrids represent an effective approach to enhancing nitrogen use efficiency grain yield. However, the impact of nitrogen fertilization on protein accumulation in low-N-tolerant hybrids remain insufficiently explored. In this paper, a two-year field orientation trial was conducted at four nitrogen fertilizer rate with the different low-N-tolerant maize hybrids.

African agriculture faces triple threats of climate change, population growth and inequality, necessitating sustainability research in agriculture that comprehensively examines social, economic, environmental, and socio-political trade-offs. To examine sustainable beef production in Botswana, this study used a mixed-method approach to explore Feedlot and Free-range cattle management systems. First, competing but overlapping factors of environmental, economic, and social sustainability in beef production were identified from literature review, and a conceptual framework for sustainability was used to assess the trade-offs inherent in both management systems.

Genomic selection (GS) is an essential tool to improve genetic gain in wheat breeding. This study aimed to enhance prediction accuracy (PA) for grain yield (GY) across various selection environments (SEs) using CIMMYT's (International Maize and Wheat Improvement Center) historical dataset. Ten years of GY data from six SEs were analyzed, with the populations of five years (2018-2023) as the validation population (VP) and earlier years (back to 2013-2014) as the training population (TP).
