Pre-sprouting Importance and Position in Potato Production

Earlier harvest of potatoes (solanum tuberosum l.) and achieve to the good yield can be influence by different treatments of the seed tubers such as pre-sprouting treatments. the aim of this study was assessment the pre-sprouting effects on the potato morphological properties and yield in the erzurum region. this experiment had two cultivars of potato as binella and slaney and included four pre-sprouting treatments as control, 23 march, 3 april and 13 april. in this experiment was investigated some properties such as flowering time, plant height, tuber number, special weight of tuber and total tuber yield. the results showed that the forth pre-sprouting increased the tuber number but its tuber yield decreased. it indicated that the under forth presprouting decreasesd the tuber size and following this case decreased the specific weight that resulted of the graphs. also, under the second pre-sprouting increased the tuber yield. the slaney cultivar had the significant differences for the plant height, tuber number, tuber yield and specific weight and more value for these properties in compare to the binella cultivar. as conclusion can be noted that the pre-sprouting has an important effects on the yield and potato morphology properties.
