The new groudnut variety TK10 has the high yield and good quality compared to other currently growing cultivars in the North of Vietnam. It has a distinct characteristics namely 100 seed weigh over 70 gr, a high pod and kernel ratio about 75-80%, the pod evarage yield ranges 39.37 to 40.8 quintal/ha and the kernel evarage yield about 29.56 to 30.72 quintal/ha that meet the market demand and is very promissing variety for many groudnut cultivation areas. A study on the appropriate cultivation techniques for TK10 showed that the optimal growing date is begining of February as main spring season and a first half of August as autumn -winter season with the density about 40 plants/m2 and one plant per hole; fertilizing rate is 945 kg/ha of the mixed fertilizers with NPK content 3:9:6, respectively. Mulchy is recommended to use by plastic membrance or rice straw to cover the whole row. A groudnut seeds is treated by chemical Enaldo 40FS with the dose 3ml/kg seed or by Trichoderma with the rate 60kg/ha that gave a higher yield about 10-20%.
