Cotton

RESEARCH INSTITUTE OF AGRICULTURE, TURKMEN AGRICULTURAL UNIVERSITY  named after SA Niyazov tested the influence  of fertilizer EDAGUM®SM on growth, development and yield of cotton plants  in farms of Maryi, Akhal, Lebap and Dashoguz velayats of Turkmenistan.

EDAGUM®SM was used for pre-planting seed treatment and single foliar application during growing season. Pre-sowing treatment enhanced the seeds germination by 9%, reduced root rot disease by 17.8%, increased the height of the main stem, promoted more bolls formation. As a result the additional cotton yield achieved 2.9-4.7 dt/ha  (8,8-14,5%). The highest additional yield from 4.0 up to 6.6 dt/ha (12,2-20,3%) was obtained in combined treatment:  cotton seeds treatment and spraying plants during the growing season.

In 2010 UZBEK COTTON Research Institute (Surkhandarya Branch) in Surkhandarya region of Uzbekistan investigated the efficacy of the fertilizer EDAGUM®SM on cotton (variety Bukhara-102). Cotton plants were sprayed twice during vegetation: in stages of budding and beginning of flowering at rates 200, 300 and 400 ml/ha. It was established that the fertilizer accelerated the bolls opening on 9,6-12,9%, increased the weight of one boll by an average of 0.1 g. As a result additional yield of cotton in 3.2-3.6 dt/ha, or 11.1 - 12.8% to control was obtained.

UZBEK COTTON Research Institute (Namangan branch) examined the effect EDAGUM®SM on cotton yield in 2010. Cotton plants which have been treated with humic fertilizer in doses of 200-400 ml/ha were 5.8-6.0 cm higher than the control ones, increase the number of disclosed cotton bolls (at 7.7-8.0%), and acceleration of flowering and reduction in lesion wilt (at 1.3-1.5%) were observed. As a result, the cotton yield increased by 3.9 dt/ha, or 12.5% to control.

UZBEK Institute of Plant Protection (Kokand branch) in the Fergana area of Uzbekistan, conducted the field trials of the fertilizer EDAGUM®SM on cotton variety "S-6524" in 2010. Cotton plants were sprayed with fertilizer twice in budding (400 ml/ha) and flowering stages (400 ml/ha). EDAGUM®SM had a significant impact on plant growth and development: an increase in plant height at flowering stage by 5 cm; increase in the total number of bolls by 11 pieces, and increase the number of disclosed cotton bolls in average by 1.2 pc. as compared with the control. Application of EDAGUM®SM helped to accelerate boll opening by 5.5%, increase in weight of one boll in average by 0.6 g. As a result, additional raw cotton yield in 4.0 dt/ha, (13.3%) was obtained.

UZBEK Research Institute of COTTON BREEDING AND SEEDAGE tested humic fertilizer EDAGUM®SM on cotton (variety C-6524) in Akkurgan district of Tashkent area of Uzbekistan in the fields of Experimental farm of the Institute in 2010. EDAGUM®SM was used for pre-treatment of seeds (200 ml/t) and two-time plants spraying during budding and flowering (400 ml/ha).

 EDAGUM®SM accelerated the emergence of cotton seedlings on 2-3 days, stimulated flowering and ripening, increased the number of bolls per plant in average by 5.6 pc., increased the weight of each boll by 1.5 g, opening bolls by 14.7 %, which contributed to the production of additional cotton yield in 4.7 dt/ha (8%) compared to control.

In the farm "MUNIS MUKARRAM" (Kuva district, Fergana area, Uzbekistan) due to foliar spray of cotton plants by fertilizer EDAGUM®SM during budding and early flowering at doses of 200-400 ml/ha was an increase in size of bolls, fiber length were obtained, which provided additional yield of raw cotton in 6-8 dt/ha, which was 25-30% to control.      

     Kazakh Research Institute of Soil Science and Agricultural Chemistry named after U.U. Uspanov in 2012 conducted tests on the use of fertilizer EDAGUM®SM on cotton in the south and south-east of Kazakhstan. Field and industrial experiments were conducted in Maktaralskiy district on light-gray soils.  Schemes of the experiments are as follows:  

Field experiment was held on experimental fields of the Kazakh Research Institute of Cotton.

1. Control

2. N₁₅₀P₈₀K₆₀

3. P₈₀K₆₀ + N_KC

4. P₈₀K₆₀ + N_KAC

5. Two-times spraying of cotton plants in stages of germination and early flowering by water solution of  EDAGUM®SM in rate of 400 ml per 300 liters of water (consumption rate is 300 liters per 1 ha).Plot area is 50 m² in 3 replicates. Total area of experiment was 750 m².

Industrial experiment was held in the fields of LLP "Ketebay" as follows:

1. Control

2. Two-times spraying of cotton plants in stages of germination and early flowering by water solution of  EDAGUM®SM the rate of 400 ml per 300 liters of water (consumption rate is 300 liters per 1 ha).

Areas of both treatments were 1 hectare.

Two-times spraying of cotton plants with water solution of EDAGUM®SM showed to be an effective agronomic technique. On treatments with 2-fold spraying by water solution of EDAGUM®SM additional yield of raw cotton in  field experiment on irrigated light gray soils was 7.8 dt/ha or 46% to control.

This effect was also confirmed by the yield data of industrial experiment, where additional yield was 8.1 dt/ha or 43%.to control.
