KubeSovA, K., J. bAlIK, o. SedlAR and l. PeKlovA, 2014. effect of ammonium fertilization by CulTAN method on dry matter accumulation and dynamics of nitrogen uptake by maize. Bulg. J. Agric. Sci., 20: 563-570 The aim of this trial was to assess the influence of nitrogenous fertilization by CULTAN (Controlled Uptake Long Term Ammonium Nutrition) method on the dynamics of above-ground biomass dry...

This article presents the results of a field experiment investigating energy efficiency grain produced by semi-dwarf genotype winter triticale at different levels agricultural inputs. The production was evaluated in two low-input and high-input cultivation practices that differed rate nitrogen fertilizer (split application) disease control. inputs associated with low were determined to be 14.5 ...

Biological efficacy of rapeseed spray oil against twospotted spider mite (Tetranychus urticae Koch) on cucumber, against European red mite [Panonychus ulmi (Koch)] on apple, green peach aphid (Myzus persicae Sulzer) on pepper and pear psylla [Cacopsylla pyri (L.)] was evaluated in seven field and three greenhouse trials at eight localities in Serbia during 2005-2008. The efficacy of rapeseed sp...

Sensor- and satellite-based determination of nitrogen uptake provides critical data in site-specific fertilization algorithms. Therefore, two basic noncontact measurement methods (sensor satellite) were investigated winter wheat, their precision was evaluated this study. Nitrogen at four characteristic growth stages (BBCH 31, BBCH 39, 55, 65) determined using algorithms based on sensor satellit...
