REPORT on research work "Study of efficiency of liquid humic fertilizer EDAGUM®SM on rice plants", State scientific establishment the All-Russia Research Institute of Rice, 2007

The field experiment was carried out on rice crops (cultivar Rapan) on chernozem-like meadow weakly solonized clay loam soil of Krasnodar Territory, with bare fallow as forecrop. The treatments were as follows: 1. Background fertilization N100P50K40; 2. Background + seeds treatment with EDAGUM®SM, 30 ml per ton; 3. Background + treatment of vegetating plants with EDAGUM®SM, 450 ml/ha during tillering (5-6 leaf); 4. Background + treatment of vegetating plants with EDAGUM®SM, 450 ml/ha during tillering and booting (8-9 leaf), 450 ml/ha.

Results:

1. Application of EDAGUM®SM promoted an increase of rice yield.

2. Treatment of rice seeds with EDAGUM®SM by a half-dry method (10 liters per ton) in a rate 30 ml/ton provided an increase of seedlings density on 4% and yield on 0.37 tons per hectare.

3. Foliar fertilizing of rice plants during a tillering phase in a rate 450 ml/ha resulted in an increase of yield on 0.51 t/ha.

4. The most significant increase of yield was obtained with plants treatment during tillering and booting phases in rates 450 ml/ha: 0.62 ton/ha.

5. The combination of seeds treatment and foliar fertilizing of rice plants with EDAGUM®CM in phases of tillering and booting enables to achieve the maximal effect from the application of this fertilizer.

6. The application of EDAGUM®SM is economically reasonable. Relative net proceeds for double treatment in rates 450 ml/ha in phases of tillering and booting achieved 3095 rub/ha (84.17 EUR/ha).

 

In 2008 EDAGUM®SМ was tested on rice (breed Khazar).

Experimental:

1) Control: N120P30K20 (without treatment of seeds and plants);

2) N120P30K20 + preplant seed treatment (220 ml of EDAGUM®SМ + 10 l of water = 1 ton of seeds);

3) N120P30K20 + foliar spray on rice plants in tillering phase (450 ml of EDAGUM®SМ + 300 l of water = 1 hectares) + foliar spray on rice plants in shoot phase (450 ml EDAGUM®SМ + 300 l of water = 1 hectares);

4) N120P30K20 + preplant seed treatment (220 ml of EDAGUM®SМ + 10 l of water = 1 ton of seeds)+ foliar spray on rice plants in tillering phase (450 ml of EDAGUM®SМ + 300 l of water = 1 hectares) + foliar spray on rice plants in shoot phase (450 ml EDAGUM®SМ + 300 l of water = 1 hectares);

5) N120P0K0 + preplant seed treatment (220 ml of EDAGUM®SМ + 10 l of water = 1 ton of seeds)+ foliar spray on rice plants in tillering phase (450 ml of EDAGUM®SМ + 300 l of water = 1 hectares) + foliar spray on rice plants in shoot phase (450 ml EDAGUM®SМ + 300 l of water = 1 hectares);

Results:

1.Application of EDAGUM®SМ promoted increase rice yield.

2.Treatment of rice seeds by EDAGUM®SМ provided increase of yield on 0.35 t/hectares.

3.Foliar feedings of rice plants by EDAGUM®SМ at rates 450 ml/hectare in tillering and shooting phases provided increase of yield on 0.53 t/hectares.

4.The most considerable additional yield – 0.67 t/hectares – was obtained at seed treatment (EDAGUM®SМ, 220 ml/t) with following foliar feedings per 450 ml/hectares in tillering and shooting phases.

5.Application of EDAGUM®SМ on trials where no phosphoric and potassium fertilizers were used resulted in no decrease in rice yield in comparison with trials where these fertilizers were applied.

6.Increase of yield on treatments with EDAGUM®SМ application occurred due to increase of rice plants quantity, grain weight per plant, weight of 1000 grains, and also owing to decrease of blind-seeds.

7.Processing of rice seeds by EDAGUM®SМ (220 ml/t) provided faster formation of shoots (2-3 days earlier), increase of shoots quantity on 3-5%, increase of their survival rate on 6-8%, and also faster coming of flowering and ripening phases (3-4 days earlier).

8.Use of EDAGUM®SМ promoted increase of rice plants provision by nitrogen on 2.5-6.2%, at seeds treatment combined with foliar feeding in tillering phase on 2,3-10,0 %.

9. No significant changes in grain quality parameters typical for rice breed Khazar was revealed due to application of EDAGUM®SМ.

 

In 2007 Open Companies AF "Slavyanskaya" (Krasnodar territory) tested fertilizer EDAGUM®SМ on rice crops (breed Rapan) on 2100 hectares.

EDAGUM®SМ was applied as single treatment in a mixture with herbicides in a rate 1 l/hectare. This reduced plant stress from influence of agrochemicals and did not require any additional expenses for its application.

As a result of using of EDAGUM®SМ rice ripened earlier, which allowed to start harvesting 5-6 days earlier. The better plants resistances to drowning, low level of blind-seed disease, even maturing of lateral sprouts, larger and smoother grain were observed. Treated crops were not damaged by blast disease of rice. In comparison with untreated trials the yield of increased on 5-7 centner/hectare

In 2010 Uzbek Scientific Research Institute of Rice conducted the field trials of fertilizer EDAGUM®SM on rice (variety "Iskander") in Tashkent and Khorezm areas of Uzbekistan and in laboratory experiments. Fertilizer was used for pre-sowing seeds treatment (200 ml/t) and during the vegetation plants were sprayed at tillering stage (400 ml/ha).

EDAGUM®SM stimulated germination energy, germination, increased the length of the stems, roots and seedlings biomass.

 As a result of EDAGUM®SM application panicle length and 1000-grain weight increased, blind-seed disease decreased, and the yield increase achieved 6.8 dt/ha (11.6%) compared to control.

Under the conditions of the Khorezm area a stimulating effect of EDAGUM®SM on growth and development of rice was confirmed. As a result of humic fertilizer application panicle length and 1000-grain weight increased, blind-seed disease decreased and yield increase achieved 12.0 dt/ha or 27.4% from the control.

Kazakh Research Institute of Soil Science and Agricultural Chemistry named after U.U. Uspanov in 2012 conducted field experiments to study the efficiency of fertilizer EDAGUM®SM on rice in the south and south-east of Kazakhstan. In the Balkhash area experiments to test the effect of EDAGUM®SM on rice yield were carried out on the territory of the soil experimental station of Ili expedition of the above institute on lands of Bakbaktinsk rural district on rice-paddy soils. Experimental design:

1. Control - untreated seeds

2. Seeds treated in water solution of EDAGUM®CM;  dose is 400 ml EDAGUM®SM + 10 l of water per 1 ton of rice seed.

3. Area of experimental plots is 100 m2; three replicates, totally 600 m2 are under experiment.

            Estimates of the biological productivity of rice shows that the recommended application rates of EDAGUM®SM in a field experiment provided positive results.  The yield gain from the pre-treatment of rice seeds of "Bakanassky" variety with water solution of  EDAGUM®SM on rice-paddy soils was 4.5 dt/ha or 15.5% to control.
