Walking through the hops fields was an awesome experience, almost like trudging through a jungle. **Rows and rows** of heavily foliaged vines were strung up on wires ten feet high, their long, straited stems twisting upward and outward. ......
Systematically, he made his way through the **hop rows**, carrying a long pole on which the hops were trained. Those wires had been hung on cross wires with large “s” hooks, so as to be readily unhooked and thrown down to the pickers, one section at a time. If they fell too close to the ground, the wires were then propped up with scissor-shaped jacks, which could easily be moved from place to place as needed.

The experiment was established in two variants: variant of irrigated plants and variant of non-irrigated plants. The irrigation was assured by means of drop irrigation distributed above the **hop rows**.
