Sažetak
The aim of this research was to investigate the impact of the drip irrigation method with the application of mineral nutrients dissolved in water for irrigation which contained all the macroelements and microelements with the appropriate amount of boron which was a key element in these studies (fertirigation) along with irrigaton. Studies were carried out on two farms (Topolnik, Mirkovac) at Belje d.d. in 2014 with four repetitions in 2015. The results were analysed statistically by analysis of variance.
The soils on which the studies were conducted are humogley.
In two climatically different years of research, the application of fertirrigation statistically justified increase of yield and sugar content in sugar beet root. It was especially been emphasised in the second year of studies which recorded very little rainfall and their schedule during the vegetation period. From sowing to extraction of sugar beet (March-October) there was 342 mm of rain, and during the summer months (June-September) only 145 mm, which caused deterioration of the larger part of the leaf surface and reduced assimilation of CO2, weaker root development and the lower sugar content with a strong retro-vegetation on non-irrigated variance. Application of the fertirrigation in 2014 increased the root yield by 14.6% and in a very dry 2015 the same agrotechnical measure increased the yield by 42.9%. Application of dissolved nutrients in the water used for irrigation (especially boron) increased digestion of sugar beet by 1.5% and significantly influenced the overall economic result of production in two years of research.
