an application of water seven days after sowing, which is a bad prac- 

 tice. The December planting was made in a seed bed which had re- 

 ceived water November 18 and December 11, respectively. The latter 

 irrigation placed the seed bed in excellent condition for planting nine 

 days later. 



The two plats of White Australian show a difference of 720 pounds 

 per acre in favor of the November 15 planting as compared with the 

 November 29 planting. There were two factors that may have had a 

 bearing on these results. The November 29 planting was made on a 

 more gravelly plat than the other, and the seed for the November 15 

 planting was home grown, while that for the other came from Yuma. 

 Seed should be locally grown, when of good quality, on account of 

 the influence of acclimatization. In the case of the heavier yield the 

 crop was irrigated subsequent to seeding, as it was with several of the 

 other plats, but in spite of this improper practice the yield was greater 

 than the White Australian grain on the poorer soil. 



Barley: Nine varieties of barley were included in the variety test 

 plats this year. All of these were sown in the fall. No spring planting 

 was made on account of previous year's trials showing the fall planting 

 superior to the same varieties planted in the spring. 



Table II gives the varieties in the order of yields per acre, and also 

 indicates the dates of planting, harvesting, irrigating, and rate of seed- 

 mg per acre. All of the seed was treated for smut with formalin, 

 which resulted in there being no smutted grain in any of the plats. All 

 of the seed was grown on the farm last year.
