The Neptune oat variety is a forage type with high yield, reaching 43 to 69 centners per hectare. It belongs to the Avena species and has a medium vegetation period of 88 to 115 days. The plant is erect with a medium-thick stem, 87 to 110 centimeters tall. The spike is semi-compact, 18-24 centimeters long, predominantly two-grained, with an average kernel plumpness of 24-25%. The 1000-kernel weight is 33-38 grams; the kernels are white, well-developed, with blunt tips and protein content ranging from 13.7-14.7%. The Neptune variety is resistant to various adverse factors, including drought, lodging, shattering, and major oat diseases such as rust, crown rust, and stem rust. It is also weakly affected by the oat aphid. Due to these qualities, the variety is recommended for cultivation in the forest-steppe and Polissia regions, where it yields 18% above the standard average. The recommended seeding rate is 4.5-5 million viable seeds per hectare, ensuring optimal plant development. The Neptune variety was developed by individual selection of elite plants from a hybrid combination of the Raduzhny and Desnyansky varieties and has been included in the State Register of Plant Varieties since 2005. It is intended for producing high-quality forage grain with good technological properties. Due to its resistance and high productivity, Neptune is a reliable choice for agricultural producers seeking stable and high oat yields.
