The effects of green manures on yields and yield quality of spring wheat
Year: 2009
Type: article
Abstract: A field experiment was conducted in the period of 2004-2006 to investigate the effect of green manure treatments on the yield and yield quality of spring wheat. In the experiment, different green manure crops were compared for amounts of N, C and organic matter applied into soil and their effect on the yield and yield quality of succeeding cereals. The amount of organic matter applied into soil was dependent on the cultivated crop. The highest amount of organic matter was applied with hybrid lucerne, the lowest, with unfertilised oats. With sowings of red clover, lucerne and hybrid lucerne, 4.91-7.70 Mg C ha -1 and 341.9-379.1 kg N ha -1 were added to soil with green material and roots. The yield of spring wheat on unfertilised soil was 2.12 Mg ha -1 , but the treatment with hybrid lucerne as a preceding crop gave an extra yield of 1.45 Mg ha -1 . Green manure crops did not have a unilateral effect on the quality of spring wheat. Grain yield grew with the increased norm of mineral nitrogen, but there was no significant improvement in quality indicators.
