The Influence Of Organic Fertilizer "Bioplant Flora" On Winter Wheat Biometric Indicators And Productivity

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 'Sirvinta1' 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 cost-effectiveness: 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 'Sirvinta 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. Fertilizer "Bioplant Flora" significantly increased all winter wheat 'Sirvinta 1' indicators: the number of plants 444-528 plants m(-2), the plant weight from 1180.56 to 1277.78 gm(-2), the number of plant stems 6,92 - 8.18, root length from 7.35 to 9.65 cm, height of sprouts from 18.5 to 20.15 cm, as we can see in Table 1. The best was Variant 4, where seeds were felted and sprayed 7 cm wheat. Comparing seeds felting and spraying, better effect had seed felting. A very important factor choosing a fertilizer is their application economical efficiency. The highest income received in variant 4 and 5, respectively, from 1132 to 1214 Ltha(-1). The difference among them is insignificant, so sufficient spray rate is 1.0 lha(-1) each time, if appling three times.
