摘要：The article describes the application results of various previous crops and pre-sowing using of nitrogen fertilizers for the planned yield for zoned buckwheat varieties in the forest-steppe of the Krasnoyarsk territory. On the basis of the conducted research it is established that statistically significant differences on average productivity of buckwheat were found between studied previous crops, the index of influence was 83.4 %. The maximum average yield increase was observed when buckwheat was sown after potatoes (41.6 c/ha), the minimum (16.4 c/ha) – after previous grain. The greatest reaction to the introduction of ammonium nitrate had Dasha variety, whose average yield for all three previous crops was 38.1 c/ha, and its highest yield was recorded after fertilized potatoes - 50.7 c/ha.
