Abstract :ÖZET Erzurum Ekolojik şartlarında dikim ve tepe alma zamanmm patateste verime ve diğer bazı agronomik karekterlere etkisini tesbit etmek için bu çalışma yapılmış, erkenci ve geç olgunlaşan 34/962 ve 49/962 çeşitler bu denemeye alınmıştır. Neticede, en fazıa verim en erken dikim zamanı olarak tayin ediıen 13 Mayıs tarihinde a.ltlnmış, tepe aımanm· veya sürgün öıdürmenin önemli etkisi görülmemiştir. SUMMARY Potato yield, the average size, the number and the largest ıuber in the hi/s as effected by date of planting and vine kil/ing. In 1969-1970 the effeet on potata yield, average size of tuber, number of tubers per hill and the largest tuber in the hills due to the date of planting and vİne killing has been investigated under Erzurum ecologecal eondition The experiments were located near number fOUf well at Atatürk University area. Four different date of planting treatments of May 13, 28 and June 13, 28 were conducted and two potata varieties, the earliest being 34{962 and the latest 49{962 used in four replieated spht plot desing. Tlıe vines were killed on the 13th 28th of May and 13 th and 28th of june. One parsel was used as a control The results of this experiment are given below. 1- The higest yield was obtained from the earliest date of planting in both of varİeties. The yie1d was icnereased 215 percent in the early planting of early varietyand 114 percent of Iate variety. 2- The number of tubers in per hil been affeeted by the date of plantlg. The number of tubers of both variety where plantea earlier, were usually greater than that of Iate planting. The percentage of inerease was 62.7 in the earlyone and 33.2 in the Iate variety. 35 3- Average weight of one tuber was olso heiger the early planting than lhat of Iate planting. 4- Time of vine kiııing has not any signİficant effect on the features of potato tubers
