The Effect of Farmyard Manure and Mineral Fertilizers on Sugar Beet Beetroot and Top Yield and Soil Chemical Parameters

In order to recommend the dose of fertilization for sugar beet under currently unstable weather conditions, we analysed beetroot and top yields, content (SC), effect on soil chemistry over a three-year period (2016–2018). All three years were characterized by different conditions. The year 2016 was very warm dry. 2017 with normal precipitation. 2018 extraordinary We compared following ten treatments: unfertilized control, farmyard manure (FYM), mineral fertilizers NPK1–4, FYM + NPK1–4. applications FYM, NPK, NPK resulted in significantly higher yields beetroots tops as while no significant differences recorded among treatments. SC not affected fertilization. application lower pH value, highest values control increased organic carbon (Corg) soil, total nitrogen (Ntot), P K concentrations. According results linear-plateau model, recommended N is 112 kg ha−1, corresponding yield 66 t ha−1.
