¹ Süleyman Demirel Üniversitesi Ziraat Fakültesi Tarla Bitkileri Bölümü – ISPARTA - This research was carried out to determine the effects on some fenological observations and biological yield of tiller, tassel and leave removal of sweet corn Isparta ecological conditions in 2000 and 2001 vegetation periods. The research was designed according to randomized block with three replications and it was used `merit` hybrit (F₁) sweet corn cultivar as experimental material.

According to two years average results; tassel period of tiller removal didn`t effect and this period was determined as 55.8 days. The tiller removal was extented the period of ear silking and this period was determined as 60.5 days. The maturity period changed between 76.1-84.0 day and treatment shorted maturity period. The first ear hight ranged from 45.3 cm to 51.1 cm and the high was reduced by the treatments. The biological yield changed between 4446-3369 kg/da, the treatmnets of the tiller, tassel and leaf removal reduced the yield. Keywords : Sweet corn, tiller removal, leaf removal, tassel removal
