Abstract

The present study was conducted with using split plot in a factorial design with three replications for two years from 1994 to 1996.The main factor was harvesting date with five levels started from 6th of Aug continued in a 15 days intervals and subplots were pre-germination at two levels (germinated or not germinated) and cultivars at three levels (Aula, Deraga & Kaiser). Pre-germination was achieved within one month, in a controlled environment conditions of required light intensity and temperature of 15-20 °C. The analysis of multiple variance was run and results showed that pre-germination positively influenced the number of stem in plants, date of germination, harvesting and lubrication which was significant at the 1% level. Date of harvest only affected the number of tubers per plant and this affect was significant at the 1% level. There was a significant difference amoung cultivars for recorded characteristics. Comparison between means indicated that the productivity of cv. Draga was significantly higher (32130 kg/ha) than the two others(Kaiser with 29930 kg/ha and Aula 29580 kg/ha) and this classified the former into a different class than the two later cultivars. There was a significant two way interaction between cultivarsand pre -germination, indicating that Kaiser and Aula responsed positively to pre-germination where as this was detrimental for Draga. Comparison of correlation coefficients showed that there were significant positive correlation between yield and above mentioned characteristics. In conclusion least past harvest lossen, despite a negative inconclusion, the cv. Draga with highest productively, least post-harvest Losses, despite a negative response to PRE-SPROUTING, is recommends for Ardebil provence in Iran.
