Forgotten or neglected arable land plants, such as buckwheat, are becoming increasingly important in crop production. Grain and one seed nuts are in the usage for humans and domestic animals diet. On the fields of the Institute of Field and Vegetable Crops, Backi Petrovac, researches were conducted in terms of conventional (2010-2012) and organic cropping systems, 2012. Analysis of the average yields showed that Novosadska buckwheat variety achieved a statistically significantly higher yield in 2010th (2,996 kg ha-1) compared to the 2011th and 2012th (p <0.01). The year showed statistical significance based on the analysis of variance. The average yields of Novosadska buckwheat variety, the variant with foliar fertilization in the conventional cropping system, were significantly higher compared with the control. The average yields amounted 1.395 kg ha-1 and were higher by 214 kg ha-1, or 18.12% compared to the control. The average plants height was 144 cm. 1000 grain weight was on the average of 23.72 g for the entire experiment. Average yields in the organic cropping system were higher in variants with foliar fertilization (1322 kg ha-1) by 7% compared to the control and plants were higher by 7.28%. Plants were higher in the organic system of cultivation by 13 cm, or 9% compared with plants grown in conventional cropping system, while the yields fell for 73 kg ha-1, respectively by 5.52%. Foliar fertilizers proved to be a possible method for yield, 1000 grain weight and plant height increasing in conventional and organic cropping systems.
