Other crops

Vandinter Semo has a reputation when it comes to green manures. However, over the years, we have built up a unique knowledge about a range of crops that we very disrespectfully call ‘other crops’. Not because we think they are less important. But simply because we do not know how best to classify them. Therefore, we would still request your attention for our forage grasses, turf grasses, corn, quinoa, leafy turnip and fibre hemp.

turf grasses

Turf grasses

Whether for greenery of infrastructure, parks, sports fields and gardens. Again, Vandinter Semo has an extensive collection of grass mixtures. Formulated with unique grass varieties and their characteristics as a starting point, for any desired application. Slow growers with a solid initial development when it comes to public green, and high density grass mixtures with repair capacity when it comes to sports fields.


Maize silage

Vandinter Semo selects maize varieties for various European maize breeding companies. The unique Dutch climate places high demands on maize varieties. Earliness, firmness and high starch content are of particular importance.

The Dutch cattle farmer is very critical when it comes to sowing maize varieties. Contract workers and advisers play an important role in the choice of maize varieties. Vandinter Semo knows this market and responds to it. Every year, we screen dozens of new varieties. Only the very best varieties are brought onto the market. Maize silage growers know us from the MOKKA maize variety, a mid-early maize variety. In 2020, Vandinter Semo expects to be on the market again with material that is worthy of the varieties catalogue.



Quinoa (Chenopodium quinoa) is native to the Andes in South America and is closely related to purslane, spinach and beet. While quinoa is not a grain, it is prepared and eaten just like couscous or rice. Quinoa has greatly increased in popularity in recent years. This is mainly because quinoa is a meat substitute alternative for people who want to eat less or no meat.

The plant can grow to 3 metres high and blooms in plumes. Depending on the variety, the woody stem is green, red or purple. Quinoa is suitable to harvest as whole plant silage. For whole plant silage, the crop is harvested by a small grain combine which chops stem pieces of 0.6 cm. The crop is harvested when the dry matter content is at least 25%; this is achieved when the plumes are in full colour. The seeds are at half dough stage.

Leafy turnip / turnip

Leafy turnip / turnip

Leafy turnip/turnip is a traditional crop which can be cultivated both as a forage crop as well as a green manure. Night frost and even moderate frost are well tolerated. When sowing this crop in the stubble, it will no longer bloom. The feed value of leaf and petiole are high.

Leafy turnip can be cultivated as forage crop and as green manure. It is related to rape seed which has been specially selected for a rapid initial growth and a high leaf production. The crop can tolerate well any night frost and even moderate frost.

Provided it is sown in good time, leafy turnip can form a huge mass. Both for fodder production and for the contribution of organic matter, that is a valuable feature.

The feed value of leaf and petiole are high. When sown too early, the crop can, however, come into flower and form coarse stems which are harder to digest for livestock.

Fibre hemp

Fibre hemp

Hemp is a relative of the hemp plant (Cannabis sativa) and is cultivated for its fibres. It is possible to process fibre hemp into wood core and bast fibre. The bast fibre is processed into raw material for paper and textile industries and is suitable as a composite material for car interiors. Wood core is processed into bedding for, amongst others, horse stables. You can also find fibre hemp in food products and animal feed.

The cultivation of fibre hemp notably takes place in North Groningen and in the peat colonies in Drenthe. Hemp produces significantly better results on clay soil than on sandy soil. Fibre hemp has a strong and deep root system, this certainly benefits the structure of the soil.
