Hemp Fiber & Grain Yield
This project is a continuation of a previous hemp project that was led by Dr. Jan Slaski at InnoTech Alberta. These trials were built on the knowledge that was gained from the previous trials and the questions that couldn't be answered the first time around.
This project combines the seeding rate and seeding date trials that were separate in the first project to study their interaction effects. The fertility trial determines the optimum rate and timing of fertilizer to maximum hemp fiber and grain yield.

Determine the effect of seeding rate (100, 250, and 400 seeds m-2), and seeding time (early, normal, and late) on hemp growth and yield for Finola and Silesia strains.
Determine the effect of different rate and timings of fertilizer application on hemp fiber and grain yield
Days to start and end of flowering and days to maturity.
Three trials were conducted at three locations each, for a total of 9 trials. The hemp fertility trial consisted of ten treatments including -
50 % N,P + 50% ESN + P + micronutrients
75 % N,P + 75% ESN + P + micronutrients
75% N,P + 25% UAN (4WAS)
Grade (yield, moisture, TKW)
100% N,P + 25% UAN (4WAS)
100% N,P + 25% UAN (8WAS)
100% N,P + 25% UAN (4WAS) + 25% UAN (8WAS)
These treatments were tested for Finola and Silesia strains of hemp. The hemp rate X date trial consisted of three seeding rates (100, 250, and 400 seeds m-2) and three timings of seeding (early, normal, and late) tested on Finola and Silesia strains.
