 Abstract

Traditional crop rotation in northern Kazakhstan is spring wheat-summer fallow monoculture (SF-W-W-W-(W-W) with fallow practiced once in 4-6 years. Summer fallow is known to cause land degradation.  Pulses are the best replacement of summer fallow but so far, they are grown on small areas. In this paper, results of long-term experiment on comparison of summer fallow replaced by three pulses followed by spring wheat are presented. Dry pea provided the highest grain yield followed by chickpea. Spring wheat grain yield was lower after pulses compared with wheat yield after summer fallow. Protein content in spring wheat grain was the same when sown after fallow or pulses in dry years while it was higher in wheat sown after pulses under favorable weather conditions. Replacing fallow with pulses provided production of valuable crops with high market values. Pulse crops were more profitable than spring wheat sown after fallow. Average annual net profit of sequences consisting of pulse crops or fallow followed by wheat was the highest on lentil-wheat followed by chickpea-wheat and the lowest was on fallow–wheat. This was due to the very high market prices of lentil and chickpea grain. This shows that summer fallow can be successfully replaced by pulse crops resulting in more profitable use of cropland and reduction of soil degradation.
