“…The importance of quality coarse fodder in ruminant feeding is high. In recent years, Italian ryegrass, which is considered a high-quality coarse fodder and whose cultivation has become widespread, is a single-annual, fodder plant (Dornelles et al, 2022). Due to its high digestibility and high content of nutrients, the plant provides an increase in yield and quality of milk and stock due to the high proportion of dry matter.…”

This research was carried out to determine the effects of different additions (urea and molasses) used with Italian ryegrass (Lolium multiflorum L.) silage on fermentation, in vitro gas production, microbiological properties, in vitro digestibility parameters, and relative fodder quality (RFQ) in silages made under laboratory conditions. The Italian grass (Lolium multiflorum L.) used in the study was chopped to an approximate size of 2–3.0 cm. Amounts of 0, 2, and 4% molasses and 0, 0.5, and 1% urea were added to the fresh material as a percentage of dry matter. Because of the urea, crude protein (CP) of Italian ryegrass silage increased, but the content of neutral detergent fibre (NDF), acid detergent fibre (ADF), and acid detergent lignin (ADL) decreased. While the addition of urea decreased the acetic acid and butyric acid concentrations of the silage, it increased the pH, lactic acid, and ammonia (NH3) content. Molasses addition increased in vitro gas production and organic matter digestibility (OMD); urea increased metabolic energy (ME) and the net energy lactation (NEL) values of silages. Urea and molasses both increased in vitro digestibility parameters, microbial protein production and synthesis, and relative fodder quality of the silage. As a result of the research, it was determined that urea and molasses could be used at contents of 1.5% and 4%, respectively, in Italian ryegrass silage.

“…Italian ryegrass is widely used for grazing and the production of hay and silage in temperate‐climate regions and subtropical regions around the world, including areas in China (Barth Neto et al, 2014; Dornelles et al, 2021; Gayer et al, 2019; Pan et al, 2018). Italian ryegrass grows rapidly and is tolerant to intensive defoliation (Pavinato et al, 2014).…”

This study aimed to investigate the effect of a soil ammonia‐oxidizing bacterial (AOB) strain on Italian ryegrass (Lolium multiflorum Lam.) regrowth. Potted Italian ryegrass was used as test material. We isolated and screened an AOB strain from the soil for use in inoculation of other soils to increase nitrification. The sequence of the two isolated and screened AOB strains (S2_8_1 and S2_7_25) were 100% similar to that of Ensifer sesbaniae and Acinetobacter pittii. The nitrification inhibitor 3,4‐dimethylpyrazole phosphate (DMPP) was also added to the soil to inhibit nitrification. The experimental design involving the inoculation of the soils with the AOB strain included seven treatments: (1) regrowth without any additives, (2) regrowth with blank enrichment medium added to the soil, (3) regrowth with S2_8_1 strain inoculation, (4) regrowth with S2_7_25 strain inoculation, (5) regrowth with DMPP added to the soil, (6) regrowth with DMPP added to the soil and with S2_8_1 strain inoculation, and (7) regrowth with DMPP added to the soil and with S2_7_25 strain inoculation. Compared with regrowth treatment without any additives, the regrowth treatment with S2_8_1 and S2_7_25 inoculations significantly increased leaf biomass by 23.5–48.6%, the leaf net photosynthetic rate by 27.9–48.5%, the rhizosphere soil nitrification rate by 43.0–144.2%, leaf cytokinin concentrations by 23.7–24.9%, and xylem sap cytokinin concentrations by 32.5–43.2%. The increase of nitrate nitrogen content in rhizosphere soil induced by S2_8_1 and S2_7_25 promoted the transfers of cytokinin from roots to leaves, resulting in the increase of cytokinin concentration in leaves. This increase in leaf cytokinin concentrations improved Italian ryegrass regrowth. However, the S2_8_1 and S2_7_25‐induced increases in the nonrhizosphere soil nitrification rate were not closely related to Italian ryegrass regrowth. The tested AOB strains have considerable potential to increase Italian ryegrass regrowth.

Nitrogen (N) and potassium (K) are essential nutrients for Italian ryegrass (Lolium multiflorum L.) growth. A 2-year field experiment with a split-plot design was conducted to study the effect of N fertilizer type combined with different K fertilizer rates on the soil mineral N and K availability, and growth characteristics of Italian ryegrass. The main plots were assigned to two N fertilizer types, controlled-release urea (CRU) and common urea. While low, moderate and high potassium chloride (KCl) rates (150, 300 and 450 kg ha−1, respectively) were assigned to the subplots. Compared with the common urea treatments, the CRU significantly increased the SPAD value, plant height, leaf area, and photosynthetic index of Italian ryegrass, which significantly prolonged the green stage of Italian ryegrass and prevented premature senescence. Moreover, the dry yields of the CRU increased by 4.5–12.5% in 2019 and 10.9–25.3% in 2020 compared with the urea, respectively. At the same time, compared with the KCl150 and KCl450 treatments, the KCl300 treatment resulted in better plant growth. Overall, the CRU × KCl300 maximized the soil inorganic N and different soil K forms, and reduced the soil N/K leaching. The root length, volume, surface area, average diameter, tips and branches were also improved, and there was a significant N × K interaction effect on the tips. The CRU combined with 300 kg ha−1 KCl fertilization enhanced crop growth by improving leaf photosynthesis, soil fertility, and yield and should be recommended as the best fertilizer ratio for Italian ryegrass production.
