Effect of pre-sowing seed treatment, type of seed beds and time of sowing on Terminalia chebula in its natural forest

In conditions of climate change, when temperature and precipitation fluctuations occur more and more frequently during the growing season, it is necessary to obtain high quality seedlings with "immunity" to various stress factors, including high weediness, the damage from which is associated with a decrease in yield (by 25 -35%) and with a deterioration in the quality of agricultural products. Due to the imbalance in production technology, seedlings are often weakened, overgrown, with a low yield per unit area and survival rate in the field. One of the solutions to this problem is the use of PP for pre-sowing seed treatment to increase the competitiveness of seedlings in the field.

Sowing Seed

Seed of Leucaena glauca (L.) Benth. germinates slowly, and irregularly unless treated before sowing to render the testa permeable to water. Treatment with sulphuric acid is effective but inconvenient to use. Experiments with hot water over a range of temperature and time are described. An effective treatment was to immerse the seed in water at 80�Cfor two minutes. After this treatment seed can be dried rapidly and stored before sowing. Seed treated in this way has retained full viability for 15 months.

Fertilization System

The article presents an analysis of the determination of the effectiveness of mineral and organic fertilizers on the yield of winter wheat grain. The studies were carried out in 2017–2020 in the Rostov region on the southern chernozem. The object of research was the Doneko winter wheat variety. The predecessor is corn for grain. Ammonium nitrate, ANP fertilizer (16-16-16) and urea were used as mineral fertilizers, which were applied in the fertilization system of winter wheat and acted as a background option in the experimental scheme. ANP fertilizer (16-16-16) was introduced when sowing winter wheat, ammonium nitrate - scattered over thawed-frozen soil and carbamide in the heading phase by foliar method. Organomineral fertilizers were represented by the following types: Ruther, Leili 2000, Siamino Pro, Gumiful Pro, Soft Guard and Double Wine MKR (monocaliphosphate) produced by Biokepharm (Switzerland). The raw material for the production of organomineral fertilizers was the algae of the warm seas Laminaria. In the field experiment, the options for the joint application of foliar application and pre-sowing seed treatment with organomineral fertilizers were also studied. The control was the option without mineral fertilizers and the option with the background of the use of mineral fertilizers (farm fertilization system). It was found out that the use of organic fertilizers Ruter (0.5 or 0.25 l / t) and Leyli (0.25 l / t) for seed treatment before sowing, the use of Soft Guard (0.2 l / ha) and Gumiful Pro ( 0.2 l / ha) in the spring tillering phase and in the flag leaf phase against the background of sowing nitroammophoska at a dose of N32P32K32, random fertilizing on thawed-frozen soil with ammonium nitrate at a dose of N40 and the use of carbamide in the heading phase at a dose of N20 increased grain yield on average for 2018–2020 compared with the control (fertilization system of the farm) by 0.73 t / ha, or 23.0%. The maximum yield increase from the root-forming agent Ruther, used for pre-sowing seed treatment, reached 0.36 t / g, or 11.3%.

The Impact

The study of the dynamics of plant growth and yield of vegetable crops (carrot variety Absheron winter (Daucus carota subsp. sativus (Hoffm.) Schьbl.) and radish variety Virovsky white (Raphanus sativus var.radicula Pers.)) was conducted in the field conditions after presowing exposure to different temperatures: I option – sowing of seeds exposed to low temperatures (for 15 days the swollen for 24 hours seeds were kept at a temperature of 0±1°С); Option II - sowing of seeds exposed to variable temperatures (for 5 days, the swollen for 24 hours seeds were exposed to variable temperatures of + 20°C (8 hours) and 0±1°C (16 hours) and then 10 days at a temperature of 0±1°C; K1 – sowing dry seeds; K2 – sowing soaked seeds. The impact on the seeds of low and variable temperatures caused an increase in growth processes, both in radish and carrot. Both studied crops showed a tendency to increase the yield to a greater extent when exposed to swollen seeds with variable temperatures. Thus, the average weight of radish crops exceeded the control variant by 47.1% and carrots by 27.6%. The yield of root crops per m2increased by 36.4% for radish and 30.0% for carrot. To increase the productivity of vegetable crops, we recommend using the studied methods of pre-sowing seed treatment in practice.
