The significance of the fallow year in the dry-farming system of the Great Konya Basin, Turkey.
AbstractAbout 20% of the area is irrigated and about 35% dry farmed using a fallow period of stubble to prevent wind erosion and hold snow in place in winter. In about 30 trials on farmers' fields during 1966-68, the contribution of moisture stored during the fallow year to the transpiration of a following wheat crop was 45 and 65%, indicating the indispensability of the fallow period. A tentative scheme for the area recommends the following: with an annual precipitation of <200mm, no wheat crop possible; with 200-260mm precipitation, 2 years of fallow to 1 year of wheat; with 260-350mm, 1 year of fallow to 1 year of wheat; with 350-450mm as in the preceding, also small N dressings; with >450mm precipitation, permanent cultivation, with N dressings replacing the fallow year.[281:132.2].
