Study the some technical methods for rice cultivation in saline soil at Duy Vinh district, Quang Nam province

1. General information

Project title:

“STUDY THE SOME TECHNICAL METHODS FOR RICE CULTIVATION IN SALINE SOIL AT DUY VINH DISTRICT, QUANG NAM
PROVINCE,”

Code number:  DHH2013-02-31

Coordinator: Trinh Thi Sen

Implementing institution: Hue College of Agriculture and Forestry, Hue University

Cooperating institution(s):

1) Mr. Vo Duc Lam, Agricultural cultivation of Duy Xuyen Cooperative, Duy Xuyen district, Quang Nam Province.

2) Mrs. Hoang Thi Thai Hoa, Department of Soil and Fertilizer, Agronomy of Faculty, Hue University of Agriculture and Forestry.

3) Mr. Duong Minh Vien, Department of Soil Science, Agricultural Faculty,  Can Tho University.

Duration: from the 1^st December, 2012 to 1^st December, 2014

2. Objectives

- To determine the suitable cropping for saline tolerance rice variety (OM8104)

- To determine the suitable potassium dose for saline tolerance rice variety (OM8104)

3. Creativeness and innovativeness

There are very few researches to determine crop season and potassium rate for the promising rice varieties in the saline soil at central Viet Nam and Quang Nam as well as. Therefore, this study has creativeness and innovativeness in theory and as facts.

4. Research results

Research study determined planting and potassium dose for the salty tolerance rice variety (OM8104) as follows:

- For crop season: The most suitable transplanting times for the OM8104 salty tolerance variety is 22^nd January in Winter–Spring, and  May 30^th and June 9^th in Summer seasons on the effected saline soil of Quang Nam province, Vietnam. Grain yield was 9.1 tons/ha for both planting times in Winter-Spring season and in 4.4 tons/ha and 4.6 tons/ha in summer seasons, respectively.

- Potassium dose: The most suitable potassium dose for the OM8104 saline tolerance variety in  Winter - Spring and Summer seasons is 60 kg K₂O/ha on the base of 100 kg N + 60 kg P₂O₅ + 8 tons/ha FYM in effected saline soil of Quang Nam province, that obtained the highest yield and economic efficiency, soil fertility improvement.

5. Products:
