Amaranth (Amaranthus hypochondriacus) is a potential C<inf>4</inf> food and forage crop with high yield and quality, which is expected to improve quality forage supply in southern Kyushu region. However, the use of amaranth as a forage crop is limited in southern Kyushu, Japan. Amaranth was seeded in early May 2020 and 2022 to test its adaptability, yield, and forage quality. These characteristics were compared with those of four typical small-grained forage species that is foxtail millet (Setaria italica), Japanese barnyard millet (Echinochloa esculenta), proso millet (Panicum miliaceum), and forage sorghum (Sorghum bicolor). In both years, the highest yield and the rate of crop growth were observed in the first harvest plants in the amaranth. In addition, amaranth also had the highest in vitro dry matter digestibility (IVDMD) and crude protein (CP) content in addition to the lowest neutral detergent fiber (NDF) content in 2020. Both IVDMD and CP content were lower in 2022, due to the fact that the crops were more mature at harvest, although NDF content was the lowest. Among small-grained forage plants, forage sorghum had the second highest yield after amaranth and the highest IVDMD in first-cut plants. The amaranth crop was extensively damaged in 2020, when 31.7% of the crop was lodged by a strong wind from typhoon No. 5. Compared to conventional small grain forage species, amaranth has the potential for high forage yields and quality. However, protecting amaranth plants from typhoon damage requires further study.

This research aimed to assess how different sowing methods and seeding rates influenced the growth, yield characteristics, and forage nutritional value for establishing American jointvetch, a tropical forage legume known for its high productivity and quality, in grasslands in southwestern Japan. The experimental treatments involved two sowing methods, row sowing (RS) and broadcast sowing (BS), and combinations of four different seeding rates (SR, 5, 10, 20, or 30 kg ha−1). The sowing methods affected dry matter yield (DMY): BS resulted in higher DMY (11.3 vs. 8.7 t DM ha−1) and leaf area index (LAI, 7.2 vs. 5.3) than RS, respectively. However, in vitro dry matter digestibility (IVDMD) and crude protein (CP) concentrations were not influenced by the sowing methods. The SR affected LAI, particularly RS, and LAI increased with increasing SR. Contrary to expectations, SR did not affect DMY, IVDMD, CP, digestible DMY, or CP yield. The findings of this investigation indicate that broadcast sowing is the superior method for planting, and even when using a reduced seeding rate of 5 kg ha−1 of seed-in-pod, there was no significant impact on the yield or forage quality of American jointvetch under the conditions examined in this study. This information will contribute to the proper management of its cultivation to ensure higher productivity for use as livestock fodder.

Amaranth (Amaranthus hypochondriacus L.) is a potential forage crop with a high yield and crude protein (CP) content; however, establishment methods need to improve for the crop to be less sensitive to typhoons. Optimal establishment, cultivation, and utilization in amaranth were examined in a variety of seasons and methods of establishment in 2021–2023. Four methods were examined: (1) direct seeding in rows, (2) direct seeding in spots, (3) soil seed balls, and (4) transplant pretreatment methods under a randomized blocked design (n = 3). Sowings every month from April to August were applied only in 2021, while establishments in April, May, and August with both pretreatment methods were applied in 2022 and 2023. The establishment in August successfully escaped damage from typhoons. The direct seeding of either rows or spots showed marginal success in establishment compared to stable establishment in pretreatment methods. In 2022 and 2023, the highest yield and CP content were achieved in soil seed balls plots in April and in both pretreated plots sown in August, respectively. The quality of silage fermentation showed a high pH, ranging from 4.52 to 6.39, due to the high CP content in 7.59–18.36% dry matter (DM). Sowing in April or August established with soil seed balls can avoid typhoon damage to have stable forage yields and can be processed with a favorable quality of amaranth silage in the region.

This study assesses the impact of defoliation applied to three developmental stages across three cropping seasons from 2021 to 2023 on growth, yield and forage quality in maize. The experimental design included three treatments: defoliation of three expanded leaves at the 3rd–4th leaf stage (DF1), the 5th–6th expanded leaves by leaf punch (DF2) and expanding leaves with the DF2 treatment (DF3) at the 6th–7th leaf stages, compared with no defoliation (control). Over three years, the most significant decrease in dry matter (DM) yield occurred in DF1 during spring sowing, while in summer sowing, the largest reduction was in DF3, both of which were correlated with changes in the number of grains per ear. The DM yields at harvest were positively correlated with plant leaf areas at the silking stage. The digestibility of forage in in vitro DM decreased concomitantly with an increase in acid detergent fiber content, indicating a decrease in forage quality. Given the frequent severe damage observed in summer sown maize and the detrimental effects of early growth stage leaf feeding on quality and quantity of spring sown maize, the application of registered insecticides is advised to reduce pest damage to maize crops.

This study was conducted to investigate the effects of sowing methods (broadcast or row sowing) and seeding rate (0.5, 1.0, 2.0 or 3.0 g/m2) on growth, yield characteristics, and forage quality of phasey bean (Macroptilium lathyroides (L.) Urb.) cv.“Murray”). Experiments were carried out in 2002 and 2003. Sowing method affected dry‐matter yield (DMY): broadcast sowing resulted in higher DMY than row sowing in 2002, and during the first harvest in 2003. Dry‐matter digestibility (DMD) and crude protein (CP) concentration were not influenced by the sowing method, except when DMD and CP of the broadcast sowing treatment increased as the plant weight increased. Contrary to expectation, seeding rate did not affect leaf area index, DMY, DMD, CP, digestible dry‐matter yield or CP yield. Even the lowest seeding rate did not influence the yield and forage quality of phasey bean, compared with the recommended higher seeding rate.

© 2019 by the authors. Licensee MDPI, Basel, Switzerland. A triple cropping system, combining spring maize, pearl millet, and twice-cut blast disease resistant Italian ryegrass, was examined for the 2016–2017 and 2017–2018 growing seasons to achieve quality herbage production in Miyazaki, southern Kyushu, Japan. The growth of the three crops reached to harvest, even though typhoon and heavy rainfall occurred. Annual dry matter (DM) yield of the triple crops was 4098 g m−2 and 4349 g m−2 in the first and second cropping seasons, respectively. The observed total digestible nutrients (TDN) were higher in spring maize (up to 68.2% and 76.8%), pearl millet (up to 60.0% and 67.9%), and Italian ryegrass (up to 71.6% and 68.6%), during the first and second season, respectively, leading to an annual TDN yield of 2357 g m−2 and 2938 g m−2. The results suggest that the present established triple cropping system is feasible for obtaining high yields with more digestible nutrients in the forages.
