Soil Science Research Section
The Soil Department is responsible for the Efficient Use of Fertilizer for crops; Research on Soil Fertility Maintenance in the soil and Site Specific Nutrient Management for Site Nutrition and Target Yield for crop yields are being carried out with the following objectives.
Objective
a) To develop techniques for maintaining plant nutrients in the soil.
b) Develop effective fertilizers for crops.
C) Develop plant nutrient management practices that can achieve regional and crop target yields.
d) Research and develop low-yield, low-yield fertilizers per crop.
e) To conduct research on soil and plant sampling techniques and to test soil and plant samples.
Ongoing Research
A) Research on sustainable crop yields in waterlogged areas
1) Study of changes in crop yields and changes in soil properties in the long run by planting two varieties of paddy annually in the same soil.
2) Study on changes in paddy yields and changes in soil properties in the long run of annual paddy-paddy-paddy and paddy-pulses-paddy cultivation in the same area.
3) The effect of using Gliricidia as a green manure on perennial crop yields:
4) Paddy – Nitrogen, nitrogen and urea based on soil tests in paddy crops. A comparative study with the Blanket Recommendation on the effect of the application of phosphorus and potassium fertilizers on crop yields on a regular basis.
5) Selection of high yield responsive paddy varieties in the field conditions for the production of special green yield paddy.
6) Fertilizer test plots will be carried out in the paddy fields to draw a line of local fertilizer response to the soil testing and fertilizer rate recommendation. (Paddy _ Yezin, Kyaukse, Kyauktada, Myaung Mya, Letpadan, The Gone, Tayaw, Mohnyin, Loikaw, Zalop, Yar paddy _ Kyaukme, Kengtung and Tayaw).
7) Fertilizer test plots will be carried out to draw the soil fertility rate curve for the legume analysis and recommendation of fertilizers in pulses.
8) Testing the effectiveness of boron in pulses (Kyaukme, Zalaw, Myingyan).
B) Research activities to improve crop production and improve social life in areas without water and soil conditions.
1) Measuring Nitrogen Efficiency in Nitrogen Deficiency Resistant Rice Varieties.
Research Results
(A) Findings of Fertilizer Research on Paddy Crops
1. Sulfur deficiency has been identified in Myanmar’s paddy fields, with a 100-pound pound of gypsum fertilizer increasing the yield by 28% to 30%.
2. Applying zinc fertilizer (zinc sulphate) at the rate of 3 pounds per acre in paddy can increase paddy yield by 10% to 15%.
3. Urea fertilizer used in paddy can be applied in batches and mixed with dry urea powder equal to the amount of urea to be applied one night before each feeding to reduce urea consumption by 30% and increase paddy yield by 15% to 20%.
4. Applying half of the amount of potash fertilizer to the crop twice during harvest and germination can reduce potash loss and increase crop yield by up to 4%.
5. Nitrogen and boron leachate can be applied to the leaves at the beginning of the crop to increase the yield of 3% to 15% in the crop.
6. Of the 106 varieties currently tested, ITA-344, Yezinya 9 and IRAT 191 rice varieties were found.
(B) Pulses Fertilizer Research Findings
1. In legumes, the application of molybdenum seeds and lentils can increase pulse yields by 30% to 40%.
2. In legumes, nitrogen and boron-containing lettuce can be applied to the leaves during flowering to increase crop yields by 30% to 35%.
