EFFECT OF BIOSTIMULANT APPLICATION IN CULTIVATION OF SPRING BARLEY
Journal Title: Acta Scientiarum Polonorum – Agricultura - Year 2017, Vol 16, Issue 2
Abstract
Background. Biostimulants support plant growth and development, induce increased resistance to stress and may have a favourable effect on yields of agricultural crops and vegetables. Material and methods. The strict field experiment was conducted over the years 2010-2011, at the Research Station of the Faculty of Agriculture and Biotechnology in Mochełek (53°13’ N; 17°51’ E). The aim of this study was an assessment of the effect of biostimulants on yield components, grain and straw yield, root weight and the accumulation of NPK and Mg in spring barley grain. The one-factor experiment with spring barley cv. Nuevo aimed to study the effect of the seaweed biostimulant Kelpak (at a rate of 2 dm3∙ha-1) and its combined application with the preparation Lithovit (at rates of 1.5 dm3∙ha-1 + 1.5 kg∙ha-1, respectively) on the biometric traits of plants and on grain yield. Results. The foliar application of the biostimulant Kelpak at a rate of 2 dm3∙ha-1 at the tillering (4-5 leaf stage) or the combined application of the preparations Kelpak 1.5 dm3∙ha-1 and Lithovit 1.5 kg∙ha-1 had a favourable effect on grain yield. The application of only Kelpak caused an increase in the fresh weight of spring barley roots, and the combined use of Kelpak and Lithovit had a favourable effect on straw weight. In both treatments, thousand grain weight was higher than in the control. After the combined application of both preparations the barley grain was characterized by the highest protein concentration. The application of only Kelpak resulted in an increased accumulation of N, P, K and Mg in barley grain. The combined application of Kelpak and Lithovit caused an increase in the accumulation of N and Mg in grain. Conclusion. The beneficial effect on yield of the biostimulant Kelpak at a rate of 2 dm3∙ha-1 or the combined application of preparations Kelpak 1.5 dm3∙ha-1 and Lithovit 1.5 kg∙ha-1 at the tillering (4-5 leaf stage) justifies the application of those preparations in the cultivation of spring barley.
