Additive Experiment

Group (#14) members: Farisha, Jasmin, Krista, Vivian

Crop: Sorghum Weed 1: Canola

Weed 2: Rye Grass

Introduction• Additive experiment• Crop: Sorghum

Weed 1: CanolaWeed 2: Rye Grass

• 3 replicates for each given density (0, 10, 15, 20…) of weed seeds, crop density remained at 10 seeds per pot

• Watered the pots 3 times per week• Observations made throughout the experiment

Germination begins:• each pot is

marked with the replicate number and treatment level

• shoots appear

End of experiment

• cut all the shoots and counted the number of plants and weighed the plants per pot

Observations

loopers, spiders, fungus…
