Annual precipitation impacts on the quantity and quality manifestation of wheat and maize yield

Year, pages: 2013, 446 - 450

Yield samples of winter wheat Triticum aestivum L. and maize Zea mays L. taken from consecutive harvests of crop years at the Nagygombos experimental site of the Szent István University have been evaluated. Impact of precipitation on yield quantity and quality was studied. In case of wheat protein, wet gluten, farinographic value and Hagberg sedimentation, while in case of maize protein, starch, oil and fibre content was evaluated. Yield figures of wheat and maize varieties have been highly variable regarding crop years. In general wheat was less affected by precipitation, but extremely high precipitation and drought also caused yield depression. Water demand of yield formation was in accordance with that of C3 – C4 physiological patterns. There were significant yield differences in different crop years. Wet gluten content of wheat samples proved to be a most stable characteristic. Protein, farinographic values and Hagberg sedimentation figures were more variable in relation with the precipitation of crop years. Yield quantity of maize proved to be more variable than quality parametres of the crop. The amount of protein was smaller, and starch values higher in rainy years. Oil and fibre parametres have shown no consequent changes that could be related to the amount of annual precipitation.
