The Influence of Bioorganic Preparations on the Productivity of Conventionaly Grown Winter Rape Activating and Saving the Use of Synthetic Chemicals

Abstract

The aim was to determine the impact of Raskila bio-organic preparation on the productivity of winter rape ‘Sunday’ grown under conventional system, in order to activate and save the use of coating Rovral aqua flo and to improve the wintering of plants. The scientific article presents the data of the conventional winter rape ‘Sunday’ growth intensity, plant formation, accumulation of dry matter, seed quality parameters, fertility data and the influence of the use of bioorganic fertilizers e. winter rape 'Sunday' seeds were coated with bioorganic preparations and synthetic coatings, and additionally sprayed with a bioorganic fertilizer solution. Agrotechnics was carried out according to the technology of winter rape growing at Aleksandras Stulginskis University Experimental station. Additional coating of winter rape seeds and additional spraying with bioorganic fertilizers had a positive influence on the processes of growth and development of winter rape. By combining seed treatments and coating with bio-organic Raskila fertilizers (3 l for 100 kg) and spray in autumn (3,0 l ha-1 ), the best results are achieved: the maximum rape seed yield was 3.87 t ha-1 and the best quality production. Bioorganic fertilizers and coating Rovral aqua flo has statistically significantly increased the following indicators of winter rape Sunday: the length of the plant (118.16-127.64 cm), the number of branches (6-10), seeds in the silique (28.27), the seed yield (3.16-3.87 t ha-1). The highest seed yield was 3.87 l ha-1, applying Nagro preparations in the autumn and the Rovral aqua flo coating and spraying Raskila plants when the rape reaches a height of 5-7 cm (BBCH 10-19). Premium yield was 86.6 percent compared to control.[...]
