### Which crop lines are there besides maize?

Alongside hybrid maize there are the oilseed sunflower, multi-purpose alfalfa and feed barley crop lines; their technical sheets are not yet published. Oilseed Sunflower: BySun and MakroSun varieties. Technical sheets in preparation. Multi-purpose Alfalfa: The perennial forage component of our feed-crop programme. Feed Barley: In growers' fields across Eastern Anatolia with the CHAMPIE variety.

### Which FAO maturity group of maize should I choose?

It depends on the length of the growing season in your area and on your sowing date. Lower FAO numbers (early varieties) suit short seasons and second-crop sowing, while higher FAO numbers (late varieties) suit long-season main-crop sowing.

Each variety sheet states the FAO group. To work out together which variety fits your field, fill in the information request form or give us a call.

### What is the difference between grain maize and silage maize?

Grain maize is grown for its mature kernels, while silage maize is grown so the whole plant can be chopped and ensiled. For grain, kernel yield, dry-down and test weight matter most; for silage, total green and dry matter yield, plant height and foliage become important.

Each variety sheet states whether the variety suits grain, silage or both.

### Should hybrid maize seed be bought again every year?

Yes, that is the recommendation. Hybrid seed is the first generation (F1) produced by crossing two different parent lines. If grain harvested from a hybrid crop is sown again, the plants segregate and lose uniformity in height, maturity and yield.

### Where are the technical sheets for the sunflower, alfalfa and barley varieties?

The technical sheets for these crop lines are in preparation and not yet published on the site. For technical information, fill in the information request form or get in touch with us.
