The influence of universal bioorganic nano fertilizer NAGRO on spring barley crop productivity

Abstract

Fertilizing field experimentation was carried out in 2012, at the Experimental station of Aleksandras Stulginskis University. Spring rape, spring barley plus under-crop, perennial grass I years of using, winter wheat are grown in four-field rotation of crops. Purpose of the experiment was to evaluate the influence fertilizer on spring barley with bioorganic universal nano fertilizers NAGRO and N60P60K70. Spring barley breed 'Luokė' was used for the experiment. The effectiveness of N60P60K70 and bioorganic universal nano fertilizers NAGRO on spring barley crop was investigated in the experiment. The research shoved that N60P60K70 and Bioorganic universal nano NAGRO fertilizers had positive effect on the yield of spring barley 'Luokė'. Grain yield increased from 8,8 % to 18,8 % and straw yield - from 10,5 % to 25,5 % when comparing with the control. Best yields were obtained when fertilizing with N60P60K70 and bioorganic universal nano fertilizers NAGRO 1 l ha-1 and sprayed twice. When fertilizing with N60P60K70and Bioorganic universal nano fertilizers NAGRO 1 l ha-1 and sprayed twice the rate of crude protein content in grains increased by 0,51 %. Grain quality was better in 2012, when grain proteins up to 10.32 %. NEM controls the maximum number of fields from 77.79 to 78.22%, oil from 2.04 to 2.12 %. Investigated potassium fertilizer and their combinations with when fertilizing with N60 P60 K70 and bioorganic universal nano fertilizers NAGRO 1 l ha-1 and sprayed twice. Investigated N60P60K70fertilizer and Bioorganic universal nano fertilizers NAGRO 1 l ha-1 and sprayed twice 1000 seed weight increased from 55.7 to 57.3 g, increase a significant impact 80.0 – 92.8 % on germination 92.5 – 95.8%.
