Show iper tore foot approximately, when applied ap-plied to one acre. Thus the profit on the water Is over four times the profit on the land alone. This being the case we should figure cir crop returns not In terms of acres of land but aere-lncheg of water. We will not then confine our fifteen acre-Inches acre-Inches of water to one acre of land ln order that we may reap the greatest great-est poHBlble tonnage on that one acre, but will spread It over a larger area, so that we can get greater returns from our water. For example, if spread the fifteen acre Inches ovet three acres of ground we will reap, according ac-cording to table No. 3, three times 13.76, or 51.28 tons as compared with 21.89 tons If the fifteen acre Inches are confined to the one acre of land Or, unlng oats as another example, w get a yield of 62 bunhela of oata with a Sluch application of water and 82 bushels with a 20-lnch application. Now, if we were to spread the 20 Inches over 4 acres of ground, making an application of 6 Inches on each acre, we would get a yield of 4 times 62, or 248 bushels of oats on thone four acres with the same amount of water that It took to produce 82 bush els on one acre. Whether or not this is a paying proposition can be determined deter-mined by solving a simple problem In arithmetic. The average cobI of producing pro-ducing and harvesting an acre of Irrigated Irri-gated oats Is about S8.00. I'llOULEM III. Twenty Inches of water over 1 acre produces 82 bushels of oats. 82 bu oats at 50c 141.00. Cost, $8.00. M profit on land and water. $10.00 profit on land only. $23.00 profit on water alone. Twenty acre Inches of water over 4 acres produces 218 bu. oats. 218 bu. oats at DOc.$124.00. Cost on 4 acres $32 00. $92 00 profit on land and water, wa-ter, $10.00 profit on land alone. $52.00 profit on water alone. Thus the profit Is more than doubled. doub-led. The maximum yield per acre ol land there, is much less important than the maximum yield per acre Inch of water. ECONQMiCAL DiSTRlBUTlOH ! Of IIGIT1 WATER i i ( 6y t M. WINSOR. Utah Agricultural College. Oregon Short Line Railroad Demonstration Dem-onstration Train Lecture. (Continued from last week.) Further experiments at the Utah experiment station give us these results: re-sults: TABLE NO. I. Relative Amounts of Water Required by Different Crops to Produce One Pound of Dry Matter. To produce one pound dry matter, potatoes required 1,778 pounds water. To produce one pound dry matter, oata required 1,208 pounds water. To produce one pound dry matter, wheat required 1,049 pounds water. To produce one pound dry matter, sugar beets required 1,029 pounds water. To produce one pound dry matter, oorn required 753 pounds water. This table shows us not only the different amounts of water requited by various crops, but also gives us ao Idea of the Immense quantity used by these plants for a small amount of stored up material. The results of other experiments will give us still further light on the suuJixn of the most economical amount of water to give the various plants. In Table No. 3 we see the yields of various crops as a result of the application ap-plication of different amounts of water ln terms of the depth in inches over one acre. The yields are given per acre. TABLE NO. 3. Amount of Water In Acre-Inches vs. Yield Per Acre. Average for Four Years. CHOP DTtli ovrr Tlcld our a-re per ai re 5 In. bZ buT 10 In. 65 bu.

Now, after studying this table for a mlnuie, if I were to ask, for example: "What would be the most economical distribution of water under these conditions con-ditions for sucar beets?" many of you would answer: "At the rate of fifteen acre-lnchea per acre." because the fifteen fif-teen Inch application gave the greatest great-est yield. liet us look at It from a new point of view. We inferred in the opening of this talk that the value of the land Is dependent to a very great extent ex-tent upon the water supply. Let us make this point a little clearer. Our lund without Irrigation is limit-nl limit-nl practically to the growing of wheat. In Utah (Idaho) the yield is about 25 bushels per acre, allowing an ample am-ple margin. Taking the figures of sev-eral sev-eral leading dry farmers the average cost of producing a crop is $5 60 per acre. Example 1 la aelf explanatory. KXAMPLB L 25 bu. wheat at 6.1t$1625. Subtracting Sub-tracting cost $.160, leaves $10.65 aa profit on land alone. Any additional profit, then, over $10.65 per acre which a farmer may obtain through Irrigation is due to the Irrigation and that alone. Comparing Com-paring these values we have, taking an average crop of nugar bee's as an example: EXAMPLE II. 20 tons at $1 .50 $S0.00 as the total return. Taking $31.00 as cost of pro ductlon. we have $'j9.00 a the profit on land and water. After subtracting $1065. the profit on land alone, we have $IS35 as the profit on the water |
