Spring wheat is major crop in northern Kazakhstan occupying about 10 million hectares. Traditionally it is grown in summer fallow-wheat rotations with varying frequency of fallow. Fallow is used for accumulation of water, control of weeds and production of nitrates from organic matter. This practice however leads to soil degradation and should be avoided. In a long-term study at Shortandy site on black soils various fallow-wheat rotations from two year to six year were compared with continuous wheat practice. The objective of the study was to find out influence of long-term wheat growing with various frequency of summer fallow on soil fertility and economics of wheat production. The wheat yield on fallow was higher than on stubble land. However, the annualized wheat grain yield was increased with lengthening of the rotation with the highest yield in continuous wheat – 88% higher as compared to alternate fallow-wheat rotation. During fifty years, the soil   organic matter content decreased from 3.90 to 2.48% in two year fallow-wheat rotation as compared to 3.28% in continuous wheat. Continuous wheat is more profitable at medium and high market prices of wheat grain. Continuous wheat growing instead of summer fallow-wheat rotation is suggested. Agricultural policy supporting adoption of No-Till and application of fertilizers should be strengthened to reduce traditionally tilled summer fallow area to minimum. The reduction of tilled summer fallow area is critical to control soil erosion and degradation.

Key words: summer fallow, continuous wheat, annualized wheat production
