Tuesday, June 1, 2010

Crop: Cabbage, Celery and Green Onion
Result: Produced higher crop yields, improved plant growth and spread of roots, and deeper, more vibrant leaf color with improved disease resistance.
Location: Sichuan Province, China

This Agrostim study was conducted in China using three cultivar vegetable species in the following experimental design:
A. Cultivar: Chinese Cabbage
Species: Brassica rapa L. pekinensis (f. Cruciferae)

B. Cultivar: Celery
Species: Apium graveolens L. (f. Umbelliferae)

C. Cultivar: Green Onion
Species: Allium fistulosum L. (Alliaceae)

Location: Pengzhou City, Chendu, Sichuan Province, China
Dates: September 1996 to June 1997

Experimental Design: 3 Separate Treatments plus Control:

A. Control: Conventional fertilizer application (NPK)
25 kilograms/mu 15:15:15 applied 3 times, plus 20 buckets of liquid farm manure applied 4 times

B. Agrostim: 1.5% (dilution in water) soil applied (root area)
Applied 3 times plus Agrostim 1% foliar application

C. Agrostim: 1% (dilution in water) foliar applied 3 times.

D. Green Leaf Fertilizer (Organic Competitor of Agrostim):
1% (dilution in water) foliar applied 3 times.

Chinese Cabbage – Brassica rapa L. pekinensis

Study Results:

1. Soil Conditions & Previous Crop Yield:

The soil is alluvial, grey-brown clay loam soil for growing rice. Previous crop was rice. The growth was even, which indicates that the soil conditions are even (homogeneous) – soil quality – Average.

2. Test Plot design:

Each of the 4 general treatments was repeated 3 times for a total of 12 replicate samples. Each test plot was 20 m3 – Groups were separated by a cleared barrier 50 cm wide for ease of management and to ensure little or no fertilizer application spread to adjacent plots.

3. Test Plot management:

Seed sowing was made on October 6, 1996, and seedlings were transplanted on November 2, 1996, spacing 0.44m x 0.6m, equivalent to 2,500 plants per mu. 75 plant holes per plot. Crop harvested on March 20, 1997.

4. Observations:

Celery – Apium graveolens L.

Study Results:

1. Soil Conditions & Previous Crop Yield:

The soil is alluvial, gray-brown clay loam soil for growing rice. Previous crop was rice. The growth was even, which indicates that the soil conditions are even (homogeneous) – soil quality – Average.

2. Test Plot design:

Each of the 4 general treatments was repeated 3 times for a total of 12 replicate samples. Random arrangement of each group. Each test plot was 20 m3 – Groups were separated by a cleared barrier 50 cm wide for ease of management and to ensure little or no fertilizer application spread to adjacent plots.

3. Test Plot management:

Seed sowing was made on August 20, 1996, and seedlings were transplanted on October 14, 1996, spacing 8.1 x 22.1 centimeters, equivalent to 37,200 plants per mu. Crop harvested on January 6, 1997.

Production by plots – Treatments B, C & D are Significantly Greater than the Control (A) by Analysis of Variance at the 0.001 Level of Significance.

Production by weight produced – Treatment B is Significantly Greater than Treatments C & D and the Control (A) and Treatment C is Significantly Greater than treatment D by ANOVA at the 0.01 Level of Significance.

Note: Significant Differences are noted by separate colors.

Additionally, the Report indicates:

Agrostim increased Chinese Cabbage yield by 280 to 410 kilograms per Mu.
Improved plant growth & spread of roots
Agrostim treated plants responded faster than control or plants receiving other Organic Fertilizer Treatments.
Agrostim treated Celery & Green Onions were significantly heavier, taller plants than the control plants or plants receiving other Organic Fertilizer Treatments.
All Agrostim plants displayed a deeper, more vibrant green leaf color. Agrostim treated plants were more disease resistant.
Based upon a production increases, at local prices the average farmer obtained a net profit increase of 2.80 to 5.30X (280% – 530%) over the cost of the Agrostim.
