The influence of production technology on yielding of spring wheat cultivars

摘要

The field experiments were conducted at the Institute of Soil Science and Plant Cultivation - State Research Institute Experimental Station in Osiny in years 2008-2010. The aim of the study was to compare spring wheat yielding depending on integratedand intensive technology. The used production technologies differed as regards the nitrogen fertilization level, chemical protection against weeds, diseases, pests and a way of straw utilization. The following cultivars were selected for the research: Bombona, Nawra, and Raweta. The weather conditions differentiated the yield of spring wheat in individual years. The wheat yield was significantly higher in 2008 as compared to 2009 and 2010, by 34.1 and 30.5%, respectively. The highest effectiveness of intensive technology, expressed as grain yield increase, in relation to the integrated technology was stated in 2009, on average by 15.6%. No influence of production technology on spring wheat yielding was stated in the others years of research. Regardlessof the applied production technology the yield increase was dependent on the number of ears per unit area and thousand grain weight.
