Show 16 YEARS OF PRY-FARM PRY-FARM EXPERI-MENTREPORTS EXPERI-MENTREPORTS The Utah Agricultural Experiment Station has Just published ns Station Bulletin 170 a report of 16 years of dry farm experiments in Utal The I report was prepared by Dr. P. S. Harris, director and agronomist ot the station, and Messrs A. F. Bracken! and I. J. Jenson, assistant agronom-j Ists who have done considerable work j on tho experiments. j MA XV PROJECTS UNDKK INVES-T1GATION INVES-T1GATION AT NEPHI The major portion of the bulletin I is devoted to a discussion of some of tho results of the seven major projects pro-jects under investigation at Nephl, including cropping systems with winter win-ter wheat, tlllago methods with win-J tor wheat, rotations with winter i wheat, winter barley, spring oats,! peas, ptatoes and corn; varietal tests, or inter and spring wheats, oats, barleys, bar-leys, spelt and emmer, and or peas, beans, corn, nnd potatoes; fertility tests with barnyard and green man-i tiro; breeding work with winter, wheats, winter barley and oats; and' a forage crop test. ALFALFA THE MOST PROMISING DRY FARM FORAGE Tho tests on forage crops as reported re-ported In tho bulletin included alfal-ra, alfal-ra, sweet clover, corn, peas, vetch, bromo grass, tall meadow oat grass, Sudan grass millet, grain sorghums nnd rape. Though some success was had with most of these crops, alfalfa alfal-fa has proven to bo the most profitable profit-able crop for forage under most conditions. con-ditions. In experiments which have been conducted yearly slnco 100G, tho averago ylold of alfalfa por year has been approximately ono ton to tho acre, while Individual years havo run ns high as a ton and a halt. Sweet clover, tall meadow oat grass, ! and brouio grass have given fair, yleld but aro open to serious objections. objec-tions. . i POTATOES AVT.RAGi: 7t HDSnKIj PER ACRK i The different varieties of potatoos as shown by extensive tables In tho fcullotln, wero found to vary very I (Continued on Page Eight) I id tcKSOFDRYFARM EXPERIMENT REPORTS RE-PORTS (Continued From Pago One) much in thnii adaptability to dry-farm dry-farm conditions.

I1KST YIKIJIIXU VAIUKTIKS OP ' SMAMj GRAINS Winter wheat, according to tho tnbuntors.ln the, bulletin, has proven to bo by fnr1the, mosl Important dry farm crop. Crimean, Turkey, Uelo-gllna Uelo-gllna and Bulgarian varieties of winter win-ter wheat have given tho 'best avor-age avor-age yields over a' long period of tlmo ranging from 26,7 to 2 liD "bushels r if ' per, ncre. J Spring wheats have proven to bo useful sometimes where1 winter wheat has failed to give a satisfactory stnnd. The beat yielding varieties of common spring wheats hsvo been Chul, Saumur, Early Uaart, Ohlrka nnd Koola with yields ranging from 13.4 down to 10.S bushels per aero. The best yielding durum spring varieties vari-eties have been Kubandn, Adjinl, Mohammed Mo-hammed lien llachlr and Velvet Don. Hnrley ranks next to wheat In yield of grain on the experimental dry rurinsj Ilulgnrian and Turkeston 1 winter vnrlelles have shown great I promise. Oats and spring barleys have not yet yielded satisfactorily on tne experimental rarms. FARMS OI'ERATKD IX BttpXS OTHKU COUNTUIS In addition to tho farm at Nephl the results on soYon othor dry farms which have been operalcd to test tho possibilities of various sections aro reported In tho bulletin. Tho farms 'in San Juan, Sevier, Tooele and Washington counties have been abandoned. aban-doned. The San Juan farm demonstrated demon-strated very conclusively that tho area was Veil adapted to dry farming farm-ing npd while crops were secured on the Sexier nnd Toonlo fnrms tho yield In most cases Indicated that ih sections weie not very promising, for dry farming. Tho "Washington count) Tarm wns used largely In tho production of pure strains of seed and was later brought under Irrlgn-Hon Irrlgn-Hon nt whjch tlmo It was abandoned. ' The farms now In operation aro t Nephl. Cedar City, Kannb. nnd Wldt-soe, Wldt-soe, Garfield county. Teh latter three are being operated to test the adaptability adap-tability of these sections to dry farming, farm-ing, the latter two of which have already shown themselves to be very nrouiialnt; sections though the work has not progressed far enough for definite conclusions.
