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 Grabów [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.Maize plants that were not cultivated by mechanical methods contained less dry matter, regardless of the composted manure dose, compared to mechanically treated plants.The dry matter content in cobs was much higher than in whole maize plants.Much less dry matter content in the cobs of maize not mechanically cultivated than in the cobs of mechanically cultivated plants.The share of seeds in the maize cob in the control treatment, was about 15% lower than in the mechanically-treated plants.An increase in organic fertilization dose, had no effect on the share of cob in maize plant structure, while the cultivation method had significant influence of this feature.
