The possibilities of increasing the production abilities of soya vegetation by seed treatment with biologically active compounds

Abstract

In three-years experiments soya seeds were treated with biologically active compounds: Lignohumate B (mixture of humic and fulvic acids), Lexin (mixture of humic and fulvic acids enriched by auxins), brassinosteroid (syntetic analogue of natural 24 epibrassinolide) and so-called complete seed treatment (mixture of saturated solution of sucrose, Lexin, fungicide Maxim XL 035FS and adjuvant on the base of pinolene Agrovital). During vegetation following characteristics were observed: field germination, density of vegetation after germination and before harvest, height of plants, height of apical part of the lowest pod from the ground and yield. The results imply that the most effective way of seed treatment is the complete seed treatment, which ensured the yield of 3.29 t of seeds per hectare (average for three years), the second best was the treatment with the compound Lexin, thanks to which the achieved yield was 3.18 t of seeds per hectare.

Effects of biologically active substances used in soybean seed treatment on oil, protein and fibre content of harvested seeds

“…The positive effect of Lexin and brassinosteroids was also shown at experiments by Štranc et al (2008) or Adamčík et al (2016). The positive influence of auxins on the division and growth of plant cells is also mentioned by Procházka et al (2015). Brassinosteroids often act in synergy with auxins (especially IAAs), which is also the cause of the positive results of the variant treated with brassinosteroid (a synthetic analogue of natural 24-epibrassinolide).…”

“…Lignohumate B is a mixture of humic acids produced in the process of organic transformation from waste wood with the ratio of humic and fulvic acids 1:1 (Procházka et al 2015).…”

The influence of pre-sowing seed treatment by biologically active compounds on soybean seed quality and yield

“…According to Egli and TeKrony (1995) and Procházka et al (2015a) fully wired and homogeneous seed stand is one of the basic assumptions of quality seed production. Figure 2 shows that the seed treatment by biologically active substances before sowing leads to higher field emergence, which is an important precondition for high-yielding crop stand.…”

“…The highest yields were harvested in variants whose One of the conditions to achieve high seed vigour is the content of a sufficient amount of storage compounds (Pazderů 2009, Procházka et al 2015a. Main ingredients in soybean are proteins and fats, which in sufficient quantities play an important role in seed germination and seedling emergence.…”

Soybean seed treatment: how do fungicides translocate in plants?

“…and thereby mitigates stand loss and protects the health of seedlings. [2][3][4][5][6][7][8] Phytophthora root rot, for example, was estimated to cause more than two million tons in yield losses in the eight top soybean producing countries around the globe, while damping-off caused by Rhizoctonia sp. was estimated at over one and a half million tons.…”
