INTRODUCTION

1. PROPERTIES OF THE STUDY
To increase productivity and yield, factors such as seeds, fertilizers, cultivation
techniques, ... play an important role, in which fertilizer is considered the main factor.
However, the long-term use of chemical fertilizers leads to high costs of investment, which
results in lower profits for farmers, as well as higher N2O emissions. On the other hand, the
excess of chemical fertilizers pollutes the soil, water and human health. The problem of crop
production increases the area of cultivated land is polluted, the fertility and productivity of the
land will reduce, causing nutrition degradation.
Research to find effective farming practices that retain high productivity while
improving soil fertility and environmental safety are essential. In addition to finding new high
yielding cultivars, organic fertilizers are recommended, which can take advantage of all
agricultural waste to produce organic fertilizer such as straw, manure, residue ... Using
organic fertilizer to reduce the amount of chemical fertilizer, improving soil fertility. Organic
fertilizers not only increase crop yields, but also increase the effectiveness of chemical
fertilizers, improve soil fertility and productivity.
Therefore, the research and application of organic fertilizers and biological products in
agricultural production to reduce chemical fertilizer, contribute to environmental protection
and building a sustainable agriculture. This is very necessary and has great significance in
agricultural production. Thua Thien Hue and central Vietnam as well, the application of
organic fertilizers and biological products has not been popularized, even very limited in the
context of the climate change towards sustainable agriculture and safe.
Based on the above issues, the topic of "Research on the effectiveness of using organic
fertilizer with Trichoderma and Pseudomonas in groundnut in Thua Thien Hue" was
conducted to select the fertilizer formula that can supply good nutrients for soil, plants and
contributing in improvement economic efficiency of groundnut production in Thua Thien
Hue.
2. PURPOSE AND OBJECTIVES

agriculture.
- The research results of the project will be new scientific advances to base bio-based
groundnut production in Thua Thien Hue and other localities.
4. SCOPE OF THE STUDY
- Research on the effect of organic fertilizer on Trichoderma and Pseudomonas in pots
in coastal sandy and gray-on-dedgraded soil at the Faculty of Agronomy, University of
Agriculture and Forestry, Hue University. The result of the pots experiment to determine the

potential formula for growth and yield in oder to develop further research in the field
conditions. Time conducting of the net house experiment from January to April, 2013.
- The research on the effectiveness of using organic fertilizer with Trichoderma and
Pseudomonas for groundnut in the field conditions. The field experiments are conducted from
December 2013 tidual yield (5.56
g/plant), followed by treatment VI (5.10 g/plant) and treatment IV (5.10 g/plant). 5,14
g/plant). The treatment with individual yields similar to control 2 were treatment III (4.77
g/plant), treatmentVII (4.88 g/plant) and control 2 gained 4.78 g/plant.
Field experiments
- Coastal sandy, treatment VI (TP50: 50) achieved the highest yield and economic
efficiency in the both cropping seasons. Winter-spring cropping seasons, yield grained
27.25 quintals per hectare and economic efficiency grained 46.175.000 VND/ha. Summerautumn crop, yield grained 15.95 quintals per hectare and economic efficiency reached
17.925.000 VND/ha. Meanwhile, the control 2 grained 22.83 quintals per hectare and
11.54 quintals per hectare, the economic efficiency grained 35,349,000 VND/ha and
7,144,000 VND/ha in 2 cropping season, respectively.
- Dedgraded soil, treatment V (TP30: 70) grained the highest yield and economic
efficiency in the both cropping seasons. Winter-spring cropping seasons, yield grained


26.45 quintals/ha and economic efficiency grained 44.175.000 VND/ha. Summer-autumn
cropping seasons, yields grained 14.39 quintals per hectare and economic efficiency
grained 14,025,000 VND/ha. Meanwhile, the control 2 grained 20.85 quintals/ha and 10.85
quintals/ha, economic efficiency grained 30,399,000 VND/ha and 5,399,000 VND/ha in 2
cropping seasons, respectively.
- Using organic fertilizers and bio-products for groundnut in the coastal sandy in
Quang Loi and the dedgraded soil in Tu Ha, Thua Thien Hue has improved the soil fertile.
Increasing organic matter content, total N content and especially potassium exchange.
Production model
The results of models at two locations showed that groundnut growth better, less pest
infection, yield and economic efficiency were higher than the control models. The model

on coastal sandy soil, profit grained 62,900,000VND/ha and cultivated VCRs was 3.87
times. The model on the dedgraded soil, profit grained 58,350,000 VND/ha and
cultivation VCR was 3.66 times.
5. CONCLUSION
The study implemented one pot experiment, eight field experiments during fours
cropping seasons and developed the best result on the demostration models at the two sites.
The final result determined the treatment of 02 tons of compost Bokashi + 40 kg N + 60 kg
P2O5 + 60 kg K2O + 400 kg lime + Trichoderma and Pseudomonas at 50:50 on the coastal
sandy and the treatment of 02 tons of organic fertilizer Bokashi + 40 kg N + 60 kg P 2O5 +
60 kg K2O + 400 kg lime + Trichoderma and Pseudomonas with the ratio 30:70 on the
dedgraded soil are the best treatments for groundnut on growth, pest and disease resistance,
physiological characters, yield and economic efficiency and some biological and chemical
indicators as well as on the coastal sandy and dedgraded soil in Thua Thien Hue.
