Field 10 Nummilohko

Basic information about the field

Area: 9,62 ha
Soil type: Humus rich coarse sand

Field is fairly even and clearly shaped. It is partially located on ground water area, which is setting some limitations for the fertilizers.

1. Mixed plantation squares (LuoVaMix)
The experiment examines mixed cultivation of woody oilseeds and legumes compared to pure crops.

Sowing density pcs/m2
Pure crops: A) fava bean Louhi 70, B) pea Ingrid 120, C) annual turning rape Synthia 250, D) annual rape Laima 150
Mixed cultivation: A+D area A 56+90, A+D area B 42+120, B+C area A 96+150, B+C area B 72+200

Viljo organic fertiliser 8-4-4
Pure pea: no fertilization
Turnip rape and oilseed rape: 500 kg/ha (40 kg N/ha)
Mixed cultivation: 1000 kg/ha (80 kg N/ha)

Fleas ate seedlings of oil plants at an early stage and them were seeded again in early June.
A few individuals of oil plants survived the first sowing and them flowering in July. The seedlings of the second sowing are falling under the weeds.

2. Mixed population -square (LuoVaMix)

The experiment examines the success of different plants as mixed crops. There are two replicates.

Oat and pea are the most successful in the grid.

3. Native grains (MoPe)
Test squares are used to study cultivation properties and there cultivated for increase of varieties of old and native seeds.

4. Hemp oil plant
The experiment observes the impact of sowing time and density on growth.
Line 1: Sown 22.5. Finola 22 kg/ha, fertilization Fertilex (6-1-2) 500 kg/ha
Line 2: Sown 22.5. Finola 27,4 kg/ha, fertilization Fertilex (6-1-2) 500 kg/ha
Line 3: Sown 30.5. Finola 30 kg/ha, fertilization Fertilex (6-1-2) 500 kg/ha

A Hemp oil plant has developed into lush in July and has begun to form seeds.

5. Pea and spring triticale whole grain silage -experiment
The experiment investigates the effect of different mixture ratios on crop yields, feed quality and harvesting technology.
Line 1 Pea Arvika 50 kg/ha and triticale Somtri 150 kg/ha
Line 2 Pea Arvika 75 kg/ha and triticale Somtri 125 kg/ha
Line 3 Pea Arvika 100 kg/ha and triticale Somtri 100 kg/ha

In July triticale Somtri has begun to put forth ears and pea Arvika blooms with purple flowers.
