3 2005 VEGETABLE CROP REPORTS Jim Valliant and Mike Bartolo Arkansas Valley Research Center Colorado State University Plots – Each plot was two beds wide (5 feet) and 25’ long. Each bed had two rows spaced 10" apart on top of the bed with an in-row spacing between plants of ~3”. Eight bed feet (8’ X 1 row) was used for yield determination. Each plot was replicated four times in the trial. For the drip trial, a single drip line was placed down the center. The furrow-irrigated onions received 96.0 inches of irrigation water and the drip-irrigated onions received 27.0 inches. Polymer Application –“AgriBlend” – (HYDROGEL + zeolite) was banded at the rate of 20 lbs/acre prior to planting on March 7. The AgriBlend was applied by hand in the area to be seeded to onions. *HYDROGEL is a cross-linked molecular structured polyacrylamide (polymer). Planted - March 8 th, 2005 (var. Ranchero – Nunhems Seeds) Harvest and Grade – September, 2005

6 2005 IRRIGATION DEMONSTRATION REPORTS Jim Valliant Cooperative Extension Colorado State University Zones – Each zone of the drip irrigation system was 8.0 acres with 60-inch beds. Three rows of onions were planted on each bed. Each row was spaced 7 inches apart. The drip lines were placed in the center of the beds about 15 inches below the surface. Eight feet of bed was harvested (8’ X 3 rows of onions) at 12 locations in each treatment for yield determination. Approximately 30.0 inches was applied through the drip-irrigation system. Polymer Application – “AgriBlend” – (HYDROGEL* + zeolite) was banded at the rate of 10 lbs/acre in the transplant furrow just prior to transplanting the seedling onions. The AgriBlend was applied immediately behind the transplant furrow-opening chisel. *HYDROGEL is a cross- linked molecular structured polyacrylamide (polymer). Transplanted – April 10, 2005 Harvest and Grade – July 26, 2005

9 2005 IRRIGATION DEMONSTRATION REPORTS Jim Valliant Cooperative Extension Colorado State University Zones – Each zone of the drip irrigation system was 5.7 acres with 60-inch beds. Six rows of onions were planted on each bed. Each row was spaced 3 inches apart. The drip lines were placed in the center of the beds approximately 8 inches below the surface. Eight feet of bed was harvested (8’ X 6 rows of onions) at nine locations in each treatment for yield determination. Approximately 26.5 inches of water was applied through the drip-irrigation system. Polymer Application – “AgriBlend” – (HYDROGEL + zeolite) polymer was banded at the rate of 10 lbs/acre at planting on March 1 and 2. The AgriBlend was applied in front of the covering wheel so that it was in the furrow with the seed. *HYDROGEL is a cross-linked molecular structured polyacrylamide (polymer). Planted - March 1, 2005 (Cometa), March 2, 2005 (Vaquero) Harvest and Grade – August 29 and 30, 2005

14 2005 IRRIGATION DEMONSTRATION REPORTS Jim Valliant Cooperative Extension Colorado State University Areas – The field was bedded with 30-inch spacing and the onions were planted at two rows per bed. The rows were 8 inches apart. Eight feet of bed was harvested (8’ X 2 rows of onions) at 9 locations in each treatment for yield determination. Polymer Application – – “AgriBlend” – (HYDROGEL* + zeolite) was banded at the rate of 10 lbs/acre in the transplant furrow just prior to transplanting the seedling onions. The AgriBlend was applied immediately behind the transplant furrow-opening chisel. *HYDROGEL is a cross-linked molecular structured polyacrylamide (polymer).
