Sunflower

In 2007 Open Societies "Druzba" (Rostov area) tested fertilizer EDAGUM®SМ on sunflower (breed PR 63 A 90).

Despite unfavorable weather conditions, single foliat treatment of sunflower by fertilizer EDAGUM®SМ in a rate 0.450 l/hectare promoted obtaining of additional yield of 3.3 centner/hecta

Joint-Stock Company "Agriko AM" conducted testing of liquid humic fertilizer EDAGUM®SМ on sunflower (crossbreed Victoria) on a base of a farm Open Company «Solnechnaya Strana» in Volgograd area. Agricultural technique of sunflower cultivation was following: surface harrowing, cultivation, application of herbicide RAP, manual weed eradication against couch grass and dindle.

Sunflower seeds treated with fertilizer EDAGUM®SМ (220 ml/ton of seeds), vegetating plants treated in a phase of 7-8 real leaves (rate of fertilizer is 0.450 l/hectares).

As a result of application of fertilizer EDAGUM®SМ a significant additional sunflower yield was obtained: 2.8 centner/hectare which is 18.1% to control.

Influence of application fertilizer EDAGUM®SМ on sunflower (crossbreed Victoria), 2007:

In 2008 Research Institute of Oil-Producting Crops n.a. V.S.Pustovoit tested the efficiency of use of fertilizer EDAGUM®SМ on Krasnodar on early sunflower (crossbreed Jupiter).

Experimental: 1) Control (without fertilizers); 2) Seeds treatment: 220 ml EDAGUM®SМ + 15 l of water per 1 ton of seeds; 3) Spraying of plants in a phase of 3 pairs of real leaves (450 ml EDAGUM®SМ + 300 l of water per hectare) + spraying of plants 14 days after the previous spraying (450 ml EDAGUM®SМ + 300 l of water per hectare); 4) Seeds treatment (220 ml EDAGUM®SМ) + spraying of plants in a phase of 3 pairs of real leaves (450 ml EDAGUM®SМ + 300 l of water per hectare) + spraying of plants 14 days after the previous spraying (450 ml EDAGUM®SМ + 300 l of water per hectares).

Results:

1. Under unfavorable weather conditions during periods of flowering and seed plumpness of sunflower (air temperature was 29.5-37.5^оС) EDAGUM®SМ promoted increase of amount of achenes in anthodia on 32-45 pieces, increase of weight of 1000 seeds on 1.1-1.6 t/hectares; maintained yield of seeds on 0.14-0.20 t/hectares (4,7-6,7 %), and yield of oil on 0.08-0.09 t/hectares or 6.0-6.7%.

2. The highest yield (3.17 t/hectares) was obtained on treatment of sunflower seeds with EDAGUM®SМ (220 ml EDAGUM®SМ + 15 l of water per1 ton of seeds) + spraying of plants in a phase of 3 real leaves (450 ml EDAGUM®SМ + 300 l of water per hectare) + spraying 14 days after (450 ml EDAGUM®SМ + 300 l of water per hecta

In 2010 Ltd. "AGROSOYUZ - Kuban" tested fertilizer EDAGUM®SM in Krasnodar area on sunflower crops on lands of farms: farm “Kolos” (sunflower variety "Jupiter", Timashevsky District), Rice-breeding factory "Krasnoarmeiskiy" (variety "Rodnik-453", Krasnoarmeiskiy District), farm "Ivan Panin "(variety "Kubansky 247 MV", Novopokrovsky district) and farm "Zhuchenko LL" (variety "Brion", Novopokrovsky district). As a result of EDAGUM®SM application a significant increase in sunflower seeds yield was obtained: from 3.0 to 4.8 dt/ha, or 16.1 -17.2%.
