| Popis: | The article discusses the cultivation of narrow-leaved lupine (Lupinus angustifolius L.) on various food backgrounds (without fertilizers; amophos + potassium sulphate + ammonium nitrate; ammophos + potassium sulphate + ammonium sulfate; ammophos).The results of the study of the influence of the background of nutrition on the yield and sowing qualities of the seeds of lupine narrow-leaved: germination energy, germination. The highest yield of lupine grain was obtained on plots without the use of mineral fertilizers – 19.49 c / ha.On fertile soils, narrow-leaved lupinedoes not respond to the use of mineral fertilizers, while the use in the experience of mixtures of mineral fertilizers ammophos + potassium sulphate + ammonium nitrate and ammophos + potassium sulphate + ammonium sulfate contributed to an increase in the size of lupine seeds.The largest seeds were obtained in plots with the application of a mixture of fertilizers ammophos + potassium sulfate + ammonium sulfate - the weight of 1000 grains was 125.0 g, which is 11.9% higher than the reference values. In all variants of the experiment, the high seed germination energy is 93.3 % (ammophos) – 99.0 % (ammophos + potassium sulfate + ammonium sulfate). High seed germination rates were obtained – from 96.5 % (without fertilizers) to 99.5% (ammophos). This indicates that the agroecological conditions of the region meet the requirements of culture. |
