The effect of organic fertilizers, mineral N, P, K, increasing doses of mineral N, and soil-climate conditions on biomass yield of maize

Popis výsledku v původním jazyce

Extreme weather conditions, such as drought and warmer climate, occur more often, significantly affecting production of arable crops and growing areas in the Czech Republic. Farming practices, especially in the field of fertilization, are also changing. To study the effect of soil-climate conditions, and the effect of organic manures (farmyard manure) and mineral fertilizers we evaluated how two consecutive seasons (2014, 2015), and six fertilizer treatments – 1) unfertilized Control, 2) farmyard manure (FYM), 3) FYM with mineral P and K (FYM+PK), 4) FYM with mineral N1PK, 5) FYM+N2PK, and 6) FYM+N3PK, affected silage maize biomass production in two localities (Ivanovice, Lukavec) with different soil-climate conditions. Our results show that application of farmyard manure (FYM) ought not to be connected with any beneficial contribution when droughts occur. Benefits of mineral fertilizers also depend on weather conditions, but mainly on soil type, where higher effect can be found on naturally poorer soils (Cambizem). Increasing doses of mineral nitrogen was not connected with an increase of biomass yield, application of 40 kg of N ha-1 (FYM+N1PK) resulted in comparable, or even higher biomass yield than in the case of higher doses of nitrogen. High quality soil type (Ivanovice, Chernozem) helps to decrease the negative impacts of unsuitable weather conditions, resulting in a lower fluctuation of biomass yield production. And finally, changing climate conditions will lead in the future to reconsideration of traditional growing areas. In: Makádi, M.
