Photosynthetic and seed yield of soybean crops depending on technological methods of cultivation in the conditions of the forest-steppe of right-bank
Journal Title: «Таврійський науковий вісник» - Year 2018, Vol 100, Issue 2
Abstract
The influence of complex application of inoculation with bacterial preparations on the basis of nitrogen fixing and phosphormobilizing bacteria “Risoactive” (2.0 l/t) + “Phosphophetrain” (0.8 l/t) and treatment of crops in the phase of the 3rd triple leaf “Omex 3X” (0.5 l/ha) + “Agrohumat” (0.5 l/ha) and in the phase of blossom “Omex Micromax” (0.5 l/ha) + “Agrohumat” (0.5 l/ha) the indicators of photosynthetic productivity of soybean crop (leaf area, photosynthetic potential, net productivity of photosynthesis, dry matter) and yield of seeds of varieties of different groups of ripeness as the basis: “Oriana” (early ripe) and “Diadema of Podillya” skirts (medium ripe). The maximum indicators of the photosynthetic apparatus of soybean plants and the yield of “Oriana” (2.69 t/ha) seeds and “Dyadema of Podillya” (2.80 t/ha) were obtained on experimental variants, which carried out double inoculation of seeds with bacterial preparations “Risoactive” (2.0 l/t) + “Phosphophetrain” (0,8 l/t) and foliar nutrition in the phase of the 3rd triple leaf “Omex 3X” (0,5 l/ha) + “Agrohumate” (0,5 l/ha) and in the phase of blossom “Omex Micromax” (0,5 l/ha) + “Agrohumat” (0.5 l/ha).
