Dun pea (hibernating type) – are fodder and food grains, winter, lower than vetch. Due to weak stems and diseases affecting the rootstock, the mature pods tend to fall under their weight. At the moment, several varieties have been developed that are more resistant to lodging, some varieties have a stronger grip on the whiskers and thus remain intact in the crop.
Use: grown for grain, but also possible for green manure, green fodder, hay (especially when grown with oats). Grown alone and in mixtures with cereals. Accumulates atmospheric nitrogen.
Cultivation features: the soils are very suitable for peas, but they should be non-acidic (pH – at least 6.0), and if they are more acidic, it is advisable to lime them. In acidic soil, nodule bacteria are less able to accumulate nitrogen, so both plants are impoverished and the goal of increasing soil N reserves is not achieved.
Peas will also grow poorly in very heavy clays or springy, hilly soils with high groundwater. Peas are one of the earliest plants that can be sown, they need moisture to germinate, so it is important not to overdry the soil in the spring. Suitable for rolling the sown field. Covering the seeds with effective nodule bacteria provides energy for seed germination, which then promotes plant growth. By the way, it is very important for nodular bacteria to have sufficient soil moisture and aeration (i.e. that the soil is not compacted).
