The influence of irrigation and nitrogen fertilization on growth of plants and grain yield of two varieties of millet (Panicum miliaceum L.) on a very light soil

The purpose of the study conducted in the years 2005–2006 in Kruszyn KrajeÅ„ski near Bydgoszcz was determining the influence of irrigation and nitrogen fertilization on morphological features of root systems as well as overground parts of millet cultivable varietes Gierczyckie and Jagna including the structure of grain yield. The plants were cultivated on a very light soil. The research shown that irri-gation significantly determined various values of morphological features of over- and undeground parts in each tested varitety of millet, where Jagna variety re-acted better on this experiment factor than Gierczyckie variety. In each variety the mass of overground parts of millet as well as the mass of grain increased more in-tensive in relation to the mass of roots and P2 (ratio of the overground-part mass and roots mass). Each variety used in the experiment reacted positive on nitrogen fertilisation, where, with no irrigation, Gierczyckie variety more effectively use higher nitrogen frtilisation doses (80-120 kg•ha-1), whereas Jagna variety lower doses (40-80 kg•ha-1). Irrigation increases the effectiveness of nitrogen fertilisa-tion for Gierczyckie variety, when nitrogen fertilisation dose reach 40-80 kg•ha-1 and for Jagna variety 40 kg•ha-1. ...

sprinkler irrigation, spring wheat, nitrogen fertilisation, baking value of grain

The aim of the research was to evaluate the effect and interaction of sprinkler irrigation and nitrogen fertilisation on the grain yield and baking value of ‘Monsun' spring wheat cultivar grown in light compacted soil. A field experiment was performed in 2013-2014 in an experimental field of the Department of Land Improvement and Agrometeorology, the UTP University of Science and Technology, at MocheÅ‚ek, in the vicinity of Bydgoszcz. It was found that sprinkler irrigation significantly increased the spring wheat grain yield. The grain from sprinkler-irrigated stands demonstrated greater plumpness; it contained significantly less protein and gluten and showed a lower sedimentation value, as compared with the grain of non-sprinkler-irrigated plants. However, the protein yield produced under sprinkler irrigation conditions was on average 11% higher, compared to the control conditions. The effect of nitrogen fertilisation on the spring wheat grain yield and quality correspond to earlier findings. Similarly to other research reports, a regular yield increase and enhanced quality of baking features along with an increase in the nitrogen rate were identified. Considering the quantitative and baking features of the grain yield, it was found that the optimal nitrogen fertilisation rate in ‘Monsun' spring wheat, in both water variants, was ...
