  3. 2005 VEGETABLE CROP REPORTS Onion Polymer Trial 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. Eachplot 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 8th, 2005 (var. Ranchero – Nunhems Seeds) Harvest and Grade – September, 2005

  6. 2005 IRRIGATION DEMONSTRATION REPORTS Hanagan Drip Irrigated Onion Polymer Demo 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 Proctor Drip Irrigated Onion Polymer Demo 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 Proctor Furrow-Irrigated Onion Polymer Demo 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).
