This paper presents the research results of some indicators of water exchange in relation to the yield of 10 varieties Oac ly, sen lai, L08, 112, 114, 118, 119, 123, TB25, 126) in spring 2013 and 2014 in Trieu Son district, Thanh Hoa province. The experimental results grouped peanut yield into 3 groups: high yield: 126, 118, TB25 (126 highest yield 3.58 kg/10 m2), low yield group: lac ly, 112, sen lai (lac ly lowest yield achieved 2.27 kg/10 m2), the remaining varieties have average yield. The varieties of high-yield group as 126, TB25, 118 has good water exchange indicator than some varieties like lac ly, sen lai, 112. Typically, high yielding varieties 126 least exchange indices most affordable water: water content in leaves reached 82.03 percent, water holding capacity 9.36 percent, the ability to absorb water 4.04 percent, transpiration intensity 11.85 mmol / m 2 / s , while varieties lac ly have the lowest yielding have water content in leaves was only 78.74 percent, water holding capacity 13.09 percent, the ability to absorb water 6.12 percent, transpiration intensity 8.75 mmol / m 2 / s . Other varieties such as L08, 123, 114, 119 valuable at the average.
