The Mekong Delta Rice Research Institute is a public scientific unit under the Vietnam Academy of Agricultural Sciences, Ministry of Agriculture and Rural Development, and is one of the leading units in researching and developing specialty rice varieties currently on the market.
In the last summer-autumn crop, JVSF cooperated with the Mekong Delta Rice Research Institute to conduct the experiment “Evaluating the impact of NEMA2 on the growth, development and yield of rice”, the experiment used the OM 5451 variety bred by the Institute and was carried out in the summer-autumn crop in O Mon district, Can Tho city.
With the application of Organic Carbon technology in NEMA2 from the soil preparation and rice seed soaking steps, it helps the seedlings have strong vitality, the ability to withstand adverse environmental conditions as well as pests and diseases, thereby increasing rice yield, bringing a bumper crop.
Experimental field at the Rice Institute – Can Tho
Each stage in the growth and development of rice plants contributes significantly to the final yield component. To clearly see the impact of Nema2 in each stage, the experiment was arranged with 4 treatments and 3 replications corresponding to 2 cultivation methods. The plots were evenly spaced to ensure objectivity in terms of water resources, weather and soil.
Implementation methods
The difference from the control experiment is that #Nema2 is added in the early stages of soil preparation and seed soaking. After 2-3 days of soaking and incubating rice seeds with Nema2 solution, the germination rate is higher, the root system develops faster (quantity and length). The rice seedlings have important premises to continue developing in the next stages. The image below of the root system at the maximum growth stage of the plant will show more clearly the outstanding development when using Nema2.
Roots corresponding to 25NSS, 45NSS, 60NSS and 75NSS
During the growth of rice plants, the Rice Institute used scientific measurement solutions, the results showed that: the rate of pests and diseases, leaf blight affecting rice using Nema2 was less, the chlorophyll index (SPAD) of leaves using Nema2 was always higher. In particular, the difference in root length of rice in both cultivation methods was clearly visible, Nema2 gave stronger and nearly 20% longer roots than normal rice.
Chart measuring some evaluation criteria
Because the plant has a deep root system that helps increase its resistance to adverse weather conditions, combined with the stiffness of the rice stalk, the lodging rate in the area applying Nema2 is significantly reduced, nearly 50% lower than rice without Nema2, especially at low sowing density, the plant almost never falls over.

In terms of yield, low sowing density using advanced farming methods combined with Nema2 gives the best results in all indicators. With traditional farming methods (common in the Mekong Delta), the T4 treatment using Nema2 but reducing the amount of fertilizer has a yield 15% higher than the T3 treatment not applying Nema2 (but using more fertilizer). This leads to a significant increase in economic efficiency when applying Nema2.
Productivity comparison chart
Close, scientific experiments in Viet Lua, as well as large-scale experiments on organic fields in Quang Tri, Long An, Kien Giang… have created solid scientific and data bases, affirming that Nema2 with its organic carbon atoms has helped improve the soil, support the growth and development of rice plants throughout the process, bringing about efficiency in yield and economic efficiency. These results help farmers in the Mekong Delta have a fundamental solution to achieve a specialized area of high-quality, low-emission rice associated with green growth.
