Effect of growth stimulants on yield and quality of grain corn grown in Piedmont subprovince of Dagestan

Abstract

Field experiments were carried out on chestnut soils of Piedmont Dagestan in 2018-2020. Hybrids of grain corn treated with different growth stimulants were the object of еру research. The experiments showed that the harvesting ripeness of hybrids ROSS 299 MV and Mashuk 355 MV occurred 2...5 days earlier after treatment with growth stimulants compared to the control. The growth stimulants used in the experiment did not have a significant effect on seed germination rate. Among the studied hybrids, the highest seed germination were observed in Mashuk 355 MV hybrid. The highest values of leaf area and net productivity of crops were in hybrid Mashuk 355 MB. Plants treated with growth regulators had higher leaf surface by 4.4% and 5.5%; 6.0 % and 8.4%, respectively. Approximately the same dynamics was recorded for photosynthesis net productivity and accumulation of dry matter. Mashuk 355 MV hybrid showed the best yield, which was 30.5; 31.5 and 32.5% higher respectively, compared to the standard. Productivity of corn hybrids treated with growth regulators increased significantly. The highest data were observed on plants treated with Megamiks N10 growth regulator, which were higher than the control data by 30.0 and 32.5%, respectively. Aminokat 30% growth regulator increased corn productivity by 23.7 and 24.7%, respectively. Sufficiently high indicators of yield structure were 10 recorded in Mashuk 355 MV hybrid in the variant with the Megamiks N10 growth stimulator.

Water-Soluble Salts Based on Benzofuroxan Derivatives—Synthesis and Biological Activity

“…At the same time, the saprophytic and pathogenic microflora of the seeds is suppressed, their germination energy increases, root formation, growth and the development of plants increase, and resistance to diseases during the growing season increases. The crop yield increases up to 30% in comparison with the control [ 36 , 37 , 38 ]. However, quite commonly used crop regulators and growth promoters are toxic and detrimental to the environment, as well as having a negative impact on human health.…”

Innovative aspects of increasing the yield and quality of corn grain in Western Siberia

“…Nowadays, there is a sufficient selection of corn varieties and hybrids for growing for green mass and grain [9][10]. For the conditions of Siberia, it is important to use early ripening hybrids of the intensive type, which have high productivity in combination with a balanced amino acid composition of proteins [11][12]. It has been shown that elements of production technology affect the quality of corn grain by increasing the concentration of essential amino acids in proteins [13][14].…”
