Show DURUM WHEAT ON DRY FARMS If Soil Is Sufficiently Retentive Fifteen Fif-teen Inches of Rainfall Is Enough for Crop Probably fully twothirds of the acreage of durum wheat Is in localities locali-ties where on an average other wheats would be a failure There are therefore about 40000000 bushels of wheat added yearly to the total production pro-duction In the United States by virtue vir-tue of the production of durum which was accomplished in the year of 1900 Although durum wheat is now a thoroughly established crop both agriculturally agri-culturally and commercially Its introduction intro-duction has been attended with many difficulties and unfortunately these difficulties havo been unwittingly brought about at times by the friends of the wheat For example it Is extremely ex-tremely Important to grow durum only where the rainfall is on an average aver-age at least below 20 Incites per annum an-num If the soil is sufficiently retentive retent-ive of moisture 15 inched Is sufficient for a good crop Whine the rainfall Is greater than 20 inches there is certain to bo a deterioration in tho quality of the kernel more so than in other wheats but because of tho great yielding power of this wheat enthusiastic farmers have grown it where It should not be grown Had have thus Injured the reputation of the wheat It Is therefore alsc true that durum wheat should never be irrigated ir-rigated In many cases under experiment experi-ment durum wheat when irrigated and grown on lands similar In every other respect to that where there was no Irrigation has furnished samples of wheat so very different from tho other oth-er that they could not be Identified by ordinary parties as being the same wheat Also durum is strictly a spring wheat under ordinary conditions condi-tions and therefore cannot be grown profitably In tho south unless sufi ciently far south to be sown in the fall or midwinter without injury by cold weather An effort is now being made by the department to develop a winter variety of durum with already al-ready partial success but from three to five years will probably yet be required re-quired to establish such a variety Durum should be kept constantly free from other kinds of wheat no more because of Injury to the other wheat however than because of Injury to the durum Importers will promptly refuse re-fuse durum wheat that has any considerable con-siderable mixture of common wheat There are several varieties of durum but the most common one grown lii tluo United States and by far the best for breadmaking Is the Kubanka The names Arnautka Wild Goose Hcloturkn and Nicaragua are synonyms i syn-onyms |
