Abstract:
This paperwork reflects the three-year research results on impacts of different agricultural practices to growth and development of rye (Secale cereale L.). This research has been performed within the framework of biological reclamation phase of deposol in the mine Stanari. The significance of growing rye is reflected in the production of grain and total biomass. The aim of the overall research is to determine the impacts of different doses of fertilizers and agromeliorative measures to yield, seed quality and other quantitative properties of rye. A three-year research (2010, 2011 and 2012) has been performed on deposol in the process of reclamation. Deposol to be researched is located on the internal dump site for overburden from the open pit Raškovac - Stanari. Field two-factor experiment was set up according to the randomized block design with four replications. The first factor (A) represents agromeliorative measures applied before and during the sowing (liming and NPK fertilizers). The second factor involves tracking the impact of different doses of nitrogen top dressing in vegetation. Measurement and statistically analysis of plant height, seed yield and 1000 grain weight has been performed. The achieved results indicate the existence of a statistical differences occurring especially between the applied treatment with nitrogen top-dressing. The maximum measured height of rye plants was 153,67 cm and average height was 128,31 cm. Maximum seed yield was 5,53 t/ha, with the average 2,60 t/ha. The average value of 1000 seeds is 37,28 g, the maximum value of 61,92 g and 12,11 g minimum. The minimum value of plant height was 86,53 cm, and grain yield was 0,35 t/ha. The highest medium plant value and grain yield were achieved in the treatments with the highest nitrogen top dressing (N54). Medium maximum value of 1000 seeds was achieved in the treatments with a dose of 27 kg/ha N. The applied treatments, along with the environmental conditions affecting the habitat of different traits measured results. The achieved results prove that rye can be grown successfully in the process of biological reclamation of deposol, and later in potential production in the permanent conversion of land.
