1 Optimal Usage of Water TAIA Lubbock Regional Meeting Jay Yates Extension Program Specialist III Risk Management Lubbock, TX

2 Declining capacity Increased efficiency Increasing energy costs Varieties with higher potential yields Texas Southern High Plains Irrigation Situation

3 Looked at the following cotton alternatives: – Fully irrigate 120 acre pivots with 300 gpm each – Irrigate 1/2 pivots, treat the rest as dryland – Irrigate 2/3 pivots, treat the rest as dryland – Drill new wells to irrigate entire pivots on owned land with 600 GPM Drilling 4 new wells for the 4 pivots on owned land at a cost of $40,000 each Water ½ pivots on rented ground * None of the alternatives included DCP Program Direct Payments FARM Assistance Analysis

10 TTU Lubbock Mesonet Site – Cumulative Reference ET from 4/15 – 9/15 – 2.36 Rainfall during the same period – 98 days of 95 degrees or more – 58 days of 100 degrees or more Official Lubbock record of 48 breaks old record from 1934 of 29 3 bale cotton in 2011 took from ac/in with 4-5 gpm per acre capacity Well irrigated pivots and drip had significantly higher net returns Observations From 2011

11 Petersburg, Texas Dryland planted May 4 – Picture taken August 25, 2011

12 Shallowater, Texas Pre-watered Only Planted May 4 – Picture taken August 25, 2011

13 North of Petersburg, Texas Yield.9 BPA Sub-Surface Drip, 1.5 GPM per acre – Picture taken August 25, 2011

14 Petersburg, Texas Yield 1.5 BPA Sub-Surface Drip, 2.5 GPM per acre – Picture taken August 25, 2011

15 Lubbock, Texas Yield 3.3 BPA Sub-Surface Drip, 4.1 GPM per acre – Picture taken August 25, 2011

16 Sandhill, Texas Yield 3.5 BPA Sub-Surface Drip, 4.5 GPM per acre – Picture taken August 25, 2011

17 South of Shallowater, Texas Yield 3.95 BPA Sub-Surface Drip, 6 GPM per acre – Picture taken August 25, 2011

18 TTU Lubbock Mesonet Site – Cumulative Reference ET from 4/15 – 9/15 – 6.24 Rainfall during the same period – 69 days of 95 degrees or more – 25 days of 100 degrees or more Official Lubbock record prior to 2011 was 29 from 1934 Official Lubbock record of 24 tied for 5 th most with bale cotton in 2012 took only slightly less irrigation than 2011 Well irrigated pivots and drip had significantly higher net returns Not Much Better in 2012

19 TTU Lubbock/Reese Mesonet Site – Cumulative Reference ET from 4/15 – 9/3 Would expect another 2.5 over next 2 weeks based on forecasts, making 2013 as high of ET as 2011 – 7.82 Rainfall during the same period Normal rainfall is for this period 33 of top 36 driest periods on record for Lubbock come between 9/15 and 4/15. (Thats why winter wheat is not as successful here) – 48 days of 95 degrees or more – 13 days of 100 degrees or more Still warmer than average (~10 days/year), but closer to average temperature compared to the past 2 years. Not as Hot and Dry in 2013 But still above average

29 GPM*GPM/AcreInches/Acre/DayInches/Acre/ Season (24/7)* What Does It Take To Apply Inches of Irrigation? * Assumes 125 acre pivot and irrigating season from April 15 to September 15

30 In 2011 with virtually no sub-soil moisture or rainfall during the growing season, it took at least 4 gpm/acre to make a profitable cotton crop. Long term analysis shows that systems with the ability to deliver less than 3 gpm/acre would be more profitable cutting irrigated acreage back to that level. Irrigation profitability is more sensitive to lower cotton prices than higher energy prices. Expected price level for 2013 would indicate that profitable irrigated yields are still attainable.
