The effect of variable mineral fertilization on yield and grain mineral composition of covered and naked oat cultivars

Abstract

Among the cereals grown in Poland, oat grain contains the highest amount of ash, composed of macro-and microelements. It has been suggested that applying increased levels of mineral fertilization, to newer cultivars of oat could have an impact on their grain yield and mineral composition. A two-factorial (2x2) field experiment was conducted for three years (1999-2001) in the south of Poland. The experiment involved two cultivars of oat, i.e. the covered cultivar Dukat and the naked cultivar Akt, and two fertilization levels, i.e. low (30 kg N, 30 kg P 2 O 5 and 45 kg K 2 O ha-1) and high (60 kg N, 60 kg P 2 O 5 and 90 K 2 O ha-1). There was no significant difference in grain yield between the studied cultivars. On the other hand, the high NPK level increased the content of Mg and Fe in the grain of Akt. At the same time, there were no significant differences in the grain content of Cu, Fe, Mn and Zn between Dukat and Akt. Overall, the high level of mineral fertilizing decreased the grain content of microelements as a result of dilution effect. The content of Cu and Zn in oat grain was suitable for human consumption according to the IUNG-PIB standards. Generally, it was shown that cv. Akt was richer in mineral elements, especially in P, K, Ca, Mg, Fe and Zn, than cv. Dukat.

Effects of reduced and traditional tillage on soil properties and diversity of diatoms under winter wheat

“…Crop growth and yield depend on the condition of the soil and the level of fertilization (NPK) and on climatic conditions (Arvidsson et al, 2013;Gajda et al, 2017;Małecka et al, 2015;Pisulewska et al, 2009). The grain yield of wheat grown in monoculture without soil inversion is usually reduced by 8-30%, depending on the site, weather conditions and crop management.…”

The effect of municipal sewage sludge on the content, use and mass ratios of some elements in spring barley biomass

“…The uptake of elements by spring barley Microelement uptake by cereals is generally low and depends on soil conditions and on the level of fertilization (Pisulewska et al 2009, Witkowicz 2016. Szoszkiewicz and Znamirowski 1989, Bergmann 1966, Falkowski et al 1996, Falkowski et al 2000.…”

Impact of bacterial leaf blight disease ( Pantoea agglomerans ) on forage yield and feeding value of oat

“…It might be due to P. agglomerans reduced the photosynthetic e ciency of oat leaves, which affected the formation and accumulation of nutrients on oat plants based on the previous research results of LBD (P. agglomerans)(Wang et al, 2022c). There are differences in growth character, forage yield and feeding value between A. nuda and A. sativa, and their resistances to biotic and abiotic stress are also different because of differences in genetic and biological characteristics(Pisulewska et al, 2009;Ma et al, 2010;Sliková et al, 2010;Ta et al, 2010;Hu et al, 2012).Tao et al (…”
