Impact of the Agricultural Four-field Crop Rotation System on the Productivity of the Ordinary Winter Wheat Variety Sadovo 1
H. Georgieva
Abstract: During the period 1991 – 2009 a study was conducted on the plot of land with Cinnamonic Forest Soil (Chromic Luvisols, WRBSR, 2006) in the Agricultural Experiment Station for Irrigated Crops, Pazardzhik on the impact of two agricultural systems – minimal and optimal conditions – on the productivity of the ordinary wheat variety. The wheat is the second culture of the four-field crop rotation system with corn for grain as a forerunner.
The study showed that the optimal and minimal soil treatment has strong impact on the sowing density.
The disc plowing is effective for growing of wheat included in crop rotation after corn.
The tested factors do not have a significant impact on the growth rate of the wheat planted on slightly weeded plot of lands.
Keywords: fertilization; herbicides; soil treatment; wheat included in four-field crop rotation
