Agronomy of New Potato Lines (2004) - 5 pages
The irrigated trials were planted on May 14 and May 28 and harvested on August 16 or Sept 16. This resulted in plots harvested at 80, 90, 105 and 120 days after planting. Separate plots were grown for each planting and harvest date in the irrigated trial. In the dryland trial, only a single combination of planting and harvest dates was used - the crop was harvested 120 days after planting. In both the dryland and irrigated trials, each treatment plot consisted of a single, 8-m long section of row. Each treatment was replicated three times in a randomized complete block design. The rows were spaced 1 m apart with 25 cm between plants within a row. The irrigated plots were watered whenever soil moisture potentials in the hills dropped below -60 kPa. Weed control was achieved through the application of herbicides and cultivation.
