Tomato – Lycopersicon esculentum

Tuesday, June 1, 2010

Crop: Tomato
Result: Tomato yield over the control plants was 42% increase.
Location: Beijing, China (PRC)

Building on extensive Tomato studies of Agrostim™ in the United States, Vietnam, India, China, Honduras, and Guatemala, a series of Agrostim™ studies were initiated at several greenhouse facilities in the Fengtai District of China (Yushu Village & Middle Shed of Xinfadi). Studies were focused on Agrostim’s comparative impacts on increased plant growth and yield, increased disease resistance, improved fruit palatability and increased shelf life.

Middle Shed of Xinfadi:

Agrostim™ applications increased tomato yield over the control plants (76.7 to 34.6 jin) which approximates a 42% yield increase. This translates into a yield improvement of 2,070 Jin/Mu (54.5%).

Yushu Village:

Agrostim™ applications increased tomato yield over the control plants (123.6 to 116.6 jin) which approximates a 6% yield increase. This translates into a yield improvement of 305 Jin/Mu (6%).

Conclusions:

Agrostim™ is an effective fertilizer for utilization on vegetable crops.
Agrostim™ is a spray application fertilizer with foliar application an effective mode of product delivery.
The soils used in the studies was relatively “good” in quality with a relatively high organic content and contained NPK. The soil pH in both studies was above 7.0 which may require a little more Agrostim™ to properly acidify the soil and stabilizing the micro-ecosystem.
The positive controls, NP synthetic fertilizer (only) applied at a rate of 77 pounds/Mu may have provided a super nutrient rich media, especially considering the starting “rich” soils used.
The ratio of synthetic fertilizer usage compared to Agrostim™ was approximately 77 to 1 (In terms of pounds applied per Mu). A cost benefit analysis may well establish Agrostim’s superior capabilities.
Additional studies to “fine tune” the exact Agrostim™ requirements on a sustained basis will clearly show the improved yields and increased disease resistance that is seen everywhere with Agrostim™ utilization.
