Todeter mine the effect of time and temperature ill warming of seed rotato befor planting an experiment of splitsplit plot design with for replication and two variaty of potato (Draga , Moren) was carrid out for three year (1991 - 93). Mai.n plot was san time of. warming Of seed potato (5°-10°- 15°) subplot was sail time of warming (9 Nar ch - 3 April - 18 April ) and variaty was subsub p l o t all fieldrecords of plant _ development st.age such as sprouting date. Time of full canopy. Number of stalk perplant vegetative growth.Tuberinitiation.ect. were thorouchli taken.The yields were analysed statistically and simple and combined basis. The results obtained no significant difference in the tim~ of warmin? seed tuber before planting and No signiUcant dif(errence in temperature in warming but the tuber that were warming in 10° C had more yield them 5°, 15°
