Received, October 3, 2016; Accepted in revised form, October 10, 2016; Approved, October 12, 2016; Available online, November 2, 2016. Cultivation of peanuts provides higher returns compared to other crops, such as; corn, soybeans, and green beans. Peanut is a commercial crop and as an important source of income for farmers either on dry land or in the paddy field of rice crop marks. Peanut risk of crop failure due to pests and diseases is smaller than the soybean. This study aims at investigating the growth and production of peanut genotypes on double Stress: drought and shade. Findings show the treatments of shade and without shade, field capacity and drought have a significant influence on the parameters at the growth phase; flowering, plant height at the age of 30 HST, plant height at the age of 60 HST, the number of leaves at the age of 30 HST, number of leaves at the age of 60 HST, the number of branches at the age of 30 HST, and the number of branches at the age of 60 HST. Treatments of shade and unshade, field capacity and drought have a significant influence on the parameters in the productive phase, namely the total number of pods on the harvest, the total number of pod contains, heavy-wet stover, and heavy dry stover. The treatments of genotypes providing the best results are strains 6 (G6) and 8 (G8) for the best growth phase in all parameters and strains 10 (G10) for the best productive phase in the parameter of the pods total and pods contains.
