However, the optimal nitrogen fertilization rate and seeding density for obtaining high yield and quality forage are still unknown. In this study, the effects of nitrogen fertilization rate and seeding density on the forage yield and quality of autumn-sown ‘Gannong No. 2’ triticale were studied. We used a split-plot design, with five nitrogen fertilization rates assigned to the main plots, namely 0 (A1), 120 (A2), 240 (A3), 360 (A4), and 480 kg N ha−1 (A5), and five seeding densities assigned to subplots: 506 × 104 (B1), 675 × 104 (B2), 843 × 104 (B3), 1011 × 104 (B4), and 1180 × 104 seeds ha−1 (B5). Significant differences in lodging rate, tiller number, hay yield, crude protein content, neutral detergent fibre, and relative feed value were observed at different fertilization levels. Significant differences were found in lodging rate, plant height, tiller number, hay yield, contents of neutral detergent fibre and acid detergent fibre, dry matter digestibility, and relative feed value among the seeding density treatments. The interaction of nitrogen fertilization rate and seeding density significantly affected forage yield and quality, with the A3B3 treatment having the highest comprehensive evaluation value. In alpine grazing areas of the Qinghai-Tibetan Plateau, 240 kg N ha−1 and 843 × 104 seeds ha−1 should therefore be used for autumn-sown triticale.","PeriodicalId":12767,"journal":{"name":"Grass and Forage Science","volume":"79 3","pages":"392-403"},"PeriodicalIF":2.7,"publicationDate":"2024-04-14","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"140602996","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"农林科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

A short-term screening trial investigated the effect of 24 additive treatments, compared to a negative control, on ensiling perennial grass in mini-silos (2.75 L) for 7 d. The additive treatments comprised different ratios of Lactiplantibacillus plantarum [IMI 507026, IMI 507027, and IMI 507028] and Pediococcus pentacaceus [IMI 507024 and IMI 507025], with or without MnSO4. Target parameters, such as low levels of fresh matter loss, pH, acetic acid, ammonia-nitrogen fraction (NH3–N/Total N), and high levels of lactic acid and ASTA, were considered for treatment selection. Eight treatments were selected based on a principal component analysis and hierarchical clustering of the target parameters. These selected treatments subsequently underwent a 100 d long-term trial using lucerne, perennial grass, and perennial grass-white clover forages. All silages treated with the eight additives exhibited an improved homolactic fermentation and a lower (p < .001) pH, acetic acid, and ethanol content than the control. Although DM losses and ASTA markedly improved in the treatments containing MnSO4 in the short-term trial, these effects were not observed in the long-term trial. These outcomes suggest that the selected additives can improve silage fermentation quality across a broad range of forages, but further studies are required to assess the impact of MnSO4 on ASTA.","PeriodicalId":12767,"journal":{"name":"Grass and Forage Science","volume":"79 2","pages":"198-210"},"PeriodicalIF":2.4,"publicationDate":"2024-03-31","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://onlinelibrary.wiley.com/doi/epdf/10.1111/gfs.12668","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"140575197","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"农林科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

We identify how grassland leys in crop rotations may help to mitigate these effects, by conserving soil organic carbon and enhancing nutrient efficiency. In particular, grasslands containing legumes enhance these benefits by providing nitrogen, and displacement of mineral N fertilizer. In crop rotations, these grasslands may transfer some of the acquired nitrogen to arable follow-on crops, thereby reducing the necessity for external inputs, while at the same time providing additional benefits, such as improvement of soil quality and reduction of weed pressure. However, there are still considerable knowledge gaps about how to optimize the community composition of grassland leys to best enhance the supply of these ecosystem services. Although the benefits of multi-species grasslands for the grassland crop have been shown repeatedly and across a large gradient of environments, further research is required to determine the benefits for follow-on crops, particularly across different environmental conditions. Here, we emphasize the importance of multi-site research, such as in the research network LegacyNet. Finally, we present management techniques that are optimized for both ecosystem services and agronomic performance in mechanically cut and grazed systems. For the latter, we consider how the inclusion of bioactive plant species can enhance animal health and lower methane emissions in grazing ruminants.","PeriodicalId":12767,"journal":{"name":"Grass and Forage Science","volume":"79 2","pages":"120-134"},"PeriodicalIF":2.4,"publicationDate":"2024-03-29","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://onlinelibrary.wiley.com/doi/epdf/10.1111/gfs.12670","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"140325614","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"农林科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Tzvel. are two common contrasted scenarios during grazing. However, the biomass and nutrient allocation in L. chinensis, as well as their contribution to yield under these conditions are unclear. Therefore, a simulated grazing experiment was conducted using a factorial design that combined two defoliation heights (conservation versus elimination of growing points) and four plant heights (18, 24, 31, and 35 cm) during two growing seasons (2020 and 2021), resulting in eight treatments. Additionally, the experiment also included two identical control treatments with a single mowing in mid-August. The results demonstrated that conservation treatments for the growing point increased the regeneration time of L. chinensis during the entire growing season in both years compared to elimination treatments for the growing point, due to the alteration in biomass allocation priority and C: N: P stoichiometric ratio between stems and leaves of L. chinensis, as well as root morphological traits. The growth strategy in the treatment with 17 cm defoliation height at 35 cm plant height demonstrated the optimal combination, resulting in stabling the accumulated DM yield of L. chinensis in both years. The findings emphasize the significance of comprehending the correlation between the growing point of L. chinensis and its yield, providing a pioneering approach to guide sustainable grazing practices for L. chinensis grassland.","PeriodicalId":12767,"journal":{"name":"Grass and Forage Science","volume":"79 3","pages":"404-422"},"PeriodicalIF":2.7,"publicationDate":"2024-03-26","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"140315382","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"农林科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Most green biorefineries rely on fresh green biomass as the feedstock, but using a stable ensiled biomass could provide benefits. We evaluated the effects of silage additive treatments on silage fermentation quality and performance in a laboratory scale liquid–solid separation to simulate the first step of a green biorefinery. In Experiment 1, red clover and fresh and wilted grass were ensiled without additive or treated with a lactic acid bacteria inoculant or a formic acid based additive. In Experiment 2, grass or red clover were treated with a fibrolytic enzyme, formic acid or a combination of them, and a control without additive was also included. Silage fermentation quality was improved by additive use. Biomass dry matter concentration was negatively related to liquid yield, but effects of additive treatments on the biorefinery performance were minor and inconsistent between different forages. Optimizing agronomic and feedstock conservation management plays an important role for the success and sustainability of the biorefinery process. Good silage management practices with minimal losses during storage should be targeted, but no clear patterns in biorefinery outputs were observed in the current study when different types of additives were used in grass and clover silage production.","PeriodicalId":12767,"journal":{"name":"Grass and Forage Science","volume":"79 2","pages":"170-178"},"PeriodicalIF":2.4,"publicationDate":"2024-03-26","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://onlinelibrary.wiley.com/doi/epdf/10.1111/gfs.12671","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"140315611","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"农林科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

As an alleviation, yet unexploited strategy, mixed ensiling of grass with agro-industrial by-products may improve the ensilability and nutritive value of drought-impaired grassland. This study investigated first whether mixed ensiling of drought-impaired grass with either sugar beet pulp (SBP), wheat gluten feed (WGF) or brewers' grains (BG) has a beneficial impact on chemical composition, fermentation characteristics, in vitro gas production (GP) and physically effective neutral detergent fibre (peNDF) of silages. Secondly, it was tested whether the application of anaerobic fungi culture supernatant (AF), mixed ruminal fluid (RF) or lactic acid bacteria (LAB) provides further advantages. Additionally, the microbial community composition was evaluated in selected silages. All silages showed satisfying conservation characteristics with high lactic acid levels and low dry matter losses, and peNDF values typically found for conserved forages. Mixed ensiling with BG substantially increased the crude protein concentration, whereas SBP increased the total degradability and WGF enhanced both. The further addition of fresh AF resulted in the overall highest lactic acid levels, especially in SBP-based silages, but without changes in in vitro GP. The in vitro GP was higher with RF, particularly in mixed silages, suggesting an improved degradability. The LAB-treated silages showed lower pH compared to controls, but had no impact on in vitro GP kinetics. Concluding, mixed ensiling holds potential to produce high-quality silages from drought-impaired grassland. The further addition of silage additives can be useful for certain substrates, but appeared not mandatory.","PeriodicalId":12767,"journal":{"name":"Grass and Forage Science","volume":"79 2","pages":"179-197"},"PeriodicalIF":2.4,"publicationDate":"2024-03-25","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://onlinelibrary.wiley.com/doi/epdf/10.1111/gfs.12669","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"140299906","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"农林科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

In Argentinean Patagonia, the effects of applying cattle dry manure (M) and urea (U) (0, 60, 120, or 240 kg N ha−1 year−1) were assessed on herbage production of irrigated fescue-lotus mixtures, as well as on the activity/abundance of autochthonous arbuscular mycorrhizal fungi and N-fixing rhizobium bacteria. We hypothesised that manure has advantages over urea in increasing forage yields while maintaining the proportion of legumes and root-associated microbiota. The 120 U, 240 U, and 240 M resulted in the greatest forage production; however, yield varied depending on the source applied. The high productivity of the 120 U and 240 U was probably due to the fast grass growth immediately after fertilization, which resulted in a depressed growth of the legume. The high yield of the swards fertilized with 240 M was probably due to slight and delayed growth of grass without legume yield decline. The highest radiation interception was found in swards with a low legume proportion, suggesting a light competition from grass fertilized with the highest urea doses, which were also consistent with the highest N and P nutritional status. The microbial activity/abundance were not affected by fertilization, but the final number of nodules was positively associated with the legume proportion. In conclusion, manure fertilization increased forage yield of the mixtures, while preserving the legume proportion and the root-associated microbiota.

An underappreciated value of these lands may be in C and N storage and cycling. However, soil organic C (SOC) and total soil N (TSN) storage under humid-temperate zone pastures have not been well characterized. A survey of 31 farms in Virginia USA characterized SOC and TSN depth distributions under a diversity of grassland management scenarios, as well as in comparison with long-term no-till cropland and woodland uses on the same farms. Root-zone enrichment calculations separated management-controlled SOC and TSN stocks from a baseline condition characterized at 30-cm depth. Total stock of SOC at 0–30-cm depth varied from 46 to 88 Mg C ha−1 (5%–95% range from 304 soil profiles) across all land uses. Root-zone enrichment of SOC was maximized under mature pastures (≥20 years old) at 38.3 ± 1.6 Mg C ha−1, which was not different from that under woodland (39.8 ± 1.2 Mg C ha−1), but was greater than under no-till cropland (28.3 ± 1.3 Mg C ha−1) and conventional-till cropland (15.1 ± 5.1 Mg C ha−1). Root-zone enrichment of TSN was optimized at stocking rate of ~1 Mg live weight ha−1, but was not affected by stocking method, N fertilization history, or low levels of hay feeding.
