Maize-forage grasses intercropping systems have been increasingly adopted by farmers because of their capacity to recycle nutrients, provide mulch, and add C soil. However, shown increase nitrous oxide (N 2 O) emissions. Some tropical cause biological nitrification inhibition (BNI) which could mitigate N O emissions in the maize cycle but reactions microbial changes that explain are little know...

We aimed to test the associative effects among forages, and between forage concentrates on in vitro digestibility of dry matter neutral detergent fibre using an artificial ruminal fermentation system. The study consisted two assays, which were evaluated three sugarcane, maize silage, Tifton 85 hay under incubation conditions (single feed or all feeds together a jar), sugarcane soybean meal and/...

Maize (Zea mays L.) is widely cultivated worldwide for food, feed, and fuel uses. forage has become a valuable feed material, there much interest in characterizing its friability, as friability may shape value through effect on ingestibility. The objective of this study was to characterize the maize based milling behavior within collection inbred lines maize. We proposed two indexes—Particle Si...

Abstract Optimizing agronomic efficiency (AE) of nitrogen (N) fertilizer use by crops and enhancing crop yields are challenges for tropical no-tillage systems since maintaining residues on the soil surface alters nutrient supply to system. Cover receiving N can provide superior biomass, cycling plant residue mineralization. The aims this study were (i) investigate application forage cover or as...

Forty-two crossbred lambs (33.4 kg initial body weight; twenty-four wethers and eighteen ewes) were used in a 42 d experiment with a 2 x 3 factorial treatment arrangement to determine effects of forage level and source on splanchnic tissue mass. Diets were 250 and 750 g/kg of chopped lucerne (Medicago sativa) (A), ryegrass (Lolium multiflorum)-wheat (Triticum aestivum) (RW) or bermudagrass (Cyn...

Density and fertilization mode are the key factors regulating crude protein synthesis in forage maize; however, there is a lack of systematic understanding regulation mechanism. Here, nitrogen/potassium ratio (N/K), free amino acid (AA) content, enzyme activities (nitrate reductase (NR), glutamine synthetase (GS) glutamic pyruvic transaminase (GPT)) content yield leaves, stems, grain maize, as ...

ABSTRACT Five tropical maize lines were tested and compared with the susceptible control line B73 for resistance to Maize stripe virus (MStV) and Maize mosaic virus (MMV), both propagatively transmitted by the planthopper Peregrinus maidis (Homoptera: Delphacidae). Resistance to each virus was evaluated separately by artificial inoculations with planthoppers viruliferous for either one virus or...

Dear Editor, Sugarcane mosaic virus (SCMV) causes severe viral diseases in maize worldwide (Fuchs and Gruntzig, 1995), resulting in significant losses in grain and forage yield in susceptible cultivars of maize and related crops. The most promising solution is to cultivate resistant varieties, which contribute to sustainable crop production. Two epistatically interacting major SCMV resistance l...

The effect of the forage source on ruminal fermentation in vitro was investigated for fine (F) and coarse (C) milled diets, using a modified Hohenheim gas production test and a semi-continuous rumen simulation technique (Rusitec). It was hypothesised that the replacement of maize silage by grass silage might lead to associative effects and that interactions related to particle size variation co...
