Abstract
The article presents the results of researches оn the effectiveness of methods of presowing sowing of seeds and outside root application of fertilizen, at different levels of mineral nutrition, on the formation of indices of individual productivity and yield of soybean seeds. The object of research – the processes of growth, development and formation of individual and seed production of soybean plants depending on fertilizer, methods of leaf-feeding and hydrothermal conditions of the region. It has been established that mineral nutrition, methods of seed dressing and outside root application of fertilizen, have had a significant impact on the formation of individual productivity indicators: the number of beans per plant, the number of seeds in a bean, a mass of 1000 seeds, and a cropindex. In particular, the number of beans per plant amounted to 29–43 un. On the background of natural fertility, for the introduction of N32P32K32 in creased to 32–50 un., for making N48P48K48 the highest was 33–57 un. Improving the level ofmineral nutrition increased the efficiency of the extra root feeding and caused an increase in the mass of 1000 seeds, as compared to control, by 2,1–2,7 g for the introduction of N32P32K32 and by 3,4–4,7 g for the introduction of N48P48K48. Among the investigated methodsof presowing seed treatment and outside root application of fertilizen, the highest (0,34–0,78 t/ha or 23,0–33,8%) increase in the yield of soybean seeds was obtained by the complex processing of seeds and two extra-root crops in different phases of soy development. The least increase in the yield of soybean seeds is provided by pre-seed treatment of seeds. Vempel K - 0,5 l/t + Oraculus seeds, 1,0 l/t + Oractal molybdenum, 0,5 l/t. The increase in control was 0,08–0,18 t/ha or 5,4–7,8 %, depending on the level of mineral nutrition. The maximum increase in the individual productivity and yield of soybean seeds, on average over two years of research: the number of beans – 56,5, seeds in the bean – 2,5 with a weight of 1000 seeds – 147,4 grams and increase in seed yield – 1,27 t/ha, formed soy plants, where seed treatment was envisaged: Pennel K - 0,5 l/t + Oraculus seeds, 1,0 l/t + Oractal molybdenum, 0,5 l/t + processing of crops in the phase 2-3 true leaves Pennant, 0,5 l/ha + crop processing in the phase of budding start: Pennant, 0,5 l/ha + Oracul boron, 1,0 l/ha + Oraculus sulfur 2,0 l/ha + Oracle zinc, 1,0 l/ha per level am mineral N48P48K48.
