THE CONTENT OF PHOSPHORUS AND POTASSIUM IN MIXTURES OF FIELD PEA AND SPRING TRITICALE DETERMINE THE QUALITY OF GREEN MASS

Abstract

Background. The cultivation of mixtures of legume and cereal can bring many benefits to agriculture, among others it can provide good quality roughage for direct feeding in the form of green fodder. The aim of this study was to evaluate the effect of the share of components in the mixture of field pea with spring triticale and the harvest date on the content of phosphorus and potassium in green matter.
Material and methods. The field experiment was conducted in 2016–2018 and two factors were studied: I – the proportion of components in the mixture: field pea – clean sowing, spring triticale – clean sowing, field pea 75% + spring triticale 25%, field pea 50% + spring triticale 50%, field pea 25% + spring triticale 75%; II – harvesting date: flowering stage of field pea, flat green pod stage of field pea.
Results. The highest content of phosphorus and potassium was found in field pea, while among the mixtures, in the one with 75% of field pea and 25% of spring triticale. A higher content of the mineral elements in question was found in mixtures harvested at the field pea flowering stage compared with mixtures harvested at the stage of the flat green pod of field pea.
Conclusion. The most favourable concentration of phosphorus and potassium in green matter is provided by a mixture with 75% of field pea and 25% of spring triticale harvested at flowering stage of field pea.
