Influence of soil management and crop rotation on characteristics that define the industrial quality of wheat

Wheat quality is affected by genetic and environmental factors such as soil , climate and cultural traits. The objective of this study was to evaluate the effect of soil management and crop rotation systems on characteristics that define wheat industrial quality (hectoliter weight, thousand-kernel we ight, milling quality, alveograph characteristics, sodium dodecyl sulphate microsedimentation test and falling number). The experimental design used w as in complete randomized blocks, with split plots and three replications. Main plot consisted of the soil management systems (no-tillage system, conv entional tillage with disc and moldboard plough and minimum tillage) and th e subplot consisted of the crop rotation systems (monoculture, one winter a nd two winters without wheat). Conventional soil preparations with discs ' plough reduced the falling number; the crop rotation systems with two winte rs without wheat increased the hectoliter weight; the monoculture of this c ereal reduced the hectoliter weight, increased the gluten strength and the values obtained in the microsedimentation test with sodium lauril sulphate; the interaction of soil management, crop rotation system and year of manag ement affected the weight of one-thousand grains and the year of cultivatio n had great influence in all characteristics of the industrial quality of w heat.
