24 Why Alternative Crops? Improve Crop Diversity Rotational Benefits Buffer Seasonal Extremes Natural Resources Conservation Sustainable Use of Limited Resources

25 Why Alternative Crops? (contd) Improve Resource Use Efficiency Value Addition & Virtual Water Changing Consumer Demand Opportunistic or Alternative Uses Market Fluctuation

26 Improve Crop Diversity Stress Tolerant Cereals N Fixing & P solubilizing Legumes Deep rooted Oil seeds

27 Rotational Benefits: Wheat Yields W-W 10bu/ac C-W 25bu/ac Same Planting Date, Variety, and Fertility in the middle of the drought Canola production makes wheat farmer a better wheat farmer.

28 Rotational Benefits: Weed Control Roundup Osprey No herbicide (WSU, FS068E)

29 Buffer Seasonal Extremes: Low and high rainfall, hail storm, wind storm, heat and freeze temperatures

30 Hail Storm, Clovis (June 8, 2014)

32 Safflower Hail Damage and Regrowth Replanted Regrowth Hail Damaged Regrowth vs. Replanted (June 9, 2014) (Aug 17, 2014)

33 Alternative Crops: Hail Damage Corn: Hail damaged Safflower: Zero Hail damage Canola: Hail damaged (Clovis, 8/8/2012)

34 Canola Freeze Injury & Recovery Late Spring Frost (Mar 28, 09) Freeze Injury (Apr 17, 09) Recovery (Apr 30, 09) (Clovis, NM)

36 Herbicide Drift Injury and Recovery Guar (Drift from neighbor, unknown herbicide, July 10, 2014) Guar (Recovered, Aug 15, 2014) Safflower is fairly tolerant to herbicide drift and recovers very well. We have not seen herbicide drift issues with Winter Canola.

37 Resource Use Efficiency Shallow Rooted Crop Nutrients, water Deep Rooted Crop Multispecies cover cropping uses similar principle. Dec 12, 06

38 Value Addition and Virtual Water Movement

39 Changing Consumer Demand: healthy food, more fiber, nutrient profile, disease prevention

40 Changing Consumer Demand: Food for Energy, etc vs. Nutrition, healthy living

41 Healthy Chips Isle: Market Place, Lubbock Flax Spread: Laxmi Delights Oat Products: Sams, Lubbock Breakfast I am tired of

42 Even in Walmart

43 Opportunistic or Alternative Uses: guar for fracking, canola meal for cattle

66 Winter Canola: Farmer Experience Minimally Irrigated Rainfed Pivot Corner

67 Tips for grazing Use untreated canola seed. Adjust rate so new growth is consumed, and remove cattle when 50% of original growth remains. Have a minimum of 25% high-fiber hay. Treat as a concentrate use a bloat preventer. Closely monitor livestock. Test forage for nitrate. Graze after a hard freeze.

68 A New Generation of Desert Crops Safflower

69 Pre-season and in-season irrigation management in safflower Experimental Design: Split Plot Main plot: Soil Profile 1. Pre-irrigation (PI) (160 mm) 2. No-pre-irrigation (NPI) (depleted soil profile) Sub plot: cultivars and irrigation levels Cultivars: 2 (S333 & PI8311) Irrigation levels: 5 I 1, I 2, I 3, I 4 and I 5 (75, 150, 225, 300 and 375 mm) NPI 6-12 Buffer PI Drip & central pivot irrigation

73 Pre-irrigation was beneficial to improve WUE and HI, however increase in irrigation level does not always aid to WUE and HI. Safflower yield responded positively to preirrigation and increased irrigation levels in both the years. Increase in yield was due to increase in head numbers, seeds per head and photosynthesis.
