Abstract: Winter wheat field experiment were carried out 2010 - 2011 m. in organic field of Aleksandras Stulginskis University Training farm in PLb – g4 Endohypogleyi – Eutric Planosol – Ple – gln – w.Experiment with winter wheat ‘Širvinta1’ was established on 21st of September, 2010, in 5 hectares plot, according to the scheme: 1. Control - “Bioplant Flora” fertilizer unused; 2. Felting of seed with “Bioplant Flora” fertilizer 1 lt-1; 3. Spraying of winter wheat, which reached 7 cm “Bioplant Flora” fertilizer 0.5 lha-1; 4. Felt of seeds 1 lt-1 and spray winter wheat, which reached 7 cm “Bioplant Flora” fertilizer 0.5 lt-1. Following parameters of winter wheat has been determined applying this scheme: seed germination energy, germination, wintering, the number of plants, plant weight, number of stems in plants, root length and shoot height, chlorophyll a and b, and the ratio of carotenoids in green mass of sprouts. In another experiment, established on 21st of September, 2010 was carried research on the preparation spray rate and frequency. The flowing scheme was applied for investigation of: yield, yield quality, biometric parameters and estimation of the costeffectiveness: 1. Unsprayed “Bioplant Flora”. 2. Sprayed with 0,5 lha-1+0,5 lha-1+0,5 lha-1; 3. Sprayed 0,75 lha-1+0,75 lha-1+0,75 lha-1; 4. Sprayed 1,0 lha-1+1,0 lha-1+ 1,0 lha-1, 5. Sprayed 1,25 lha-1+1,25 lha-1+1,25 l ha-1. The investigation has showed that in organic plot of Aleksandras Stulginskis University Training farm “Bioplant Flora” fertilizer significantly increased all winter wheat ‘Širvinta 1’ characteristics: seed germination from 89.5 to 93.4 percent, germination energy from 88.3 to 91.9 percent, wintering from 89.4 to 93.7 percent. The most prominent difference was noted in Variant 4, where seeds were felted and sprayed 7 cm wheat. Comparing seeds felting and spraying, there seed felting had greatest effect
