The Effect of Available Phosphates on Yields of Vegetable and Beet Crop Rotations, their Bioenergetic and Economic Efficiency.

摘要

ABSTRACT The article presents data on the effect of the available phosphates on crop yields of vegetable and beet crop rotations and their economical efficiency. The highest yield of sugar beet (480-490 kg/ha, 2012) can be obtained applying a double dose rate of phosphorus (P180) at seasonal average soil content of labile phosphorus more than 45 mg/kg and soluble phosphates more than 440 mg/kg of soil.
