Abstract

The aim of the study was the assessment of productivity of maize and sorghum in depend on cultivation method and fertilizer dose cropped in ecological system. The study was conducted at the Institute of Soil Science and Plant Cultivation - Agricultural Experimental Station Grabow [Poland]. The first order factor was cultivation method and the second factor were composted manure dose. The study showed that the use of mechanical weed control in the cultivation of maize and sorghum resulted in a significant increase in the fresh matter yield compared to the control treatment. Increasing composted manure dose positively affected the yield of both plant species. The yield of fresh matter of maize fertilized with a dose of 20t ha-1 in the treatment without weed control, was by about 15% lower than yield of maize fertilized with a twice higher manure dose.
