Willamette Valley

150-250 day season; warm days, cool nights; length of season may very considerably from year to year

Muskmelon and Tomato Production in Response to Plant Protection (1988)

Introduction

Tomato and muskmelon production in the Willamette Valley is limited by cool springs, a short growing season, and relatively cool nights, even during mid-summer. Cultural techniques to increase the mean air and soil temperature around plants, such as black plastic ground mulch, floating row covers, and tunnels, have hastened development and increased yield of both these crops.

Introduction

Control of virus-vectoring aphids is essential in potato seed production to exclude viruses such as potato virus Y (PVY) and leaf roll. Floating row covers might protect plants from insect attack, reducing the need for insecticides.
