Öner CANAVAR*, Mustafa Ali KAYNAK Adnan Menderes University, Faculty of Agriculture, Department of Field Crops, Aydın - TURKEY Received: Abstract: This study was conducted in the experiment fields at the Field Crops Department of the Faculty of Agriculture at Adnan Menderes University in 2004-2005. The experiment was performed in a split-plot design with 3 replications. The goals of this study were to determine the appropriate planting date for peanut under the ecological conditions of Aydın and to investigate the effect of different planting dates on some agronomic traits, yield, and yield components of 3 commercial peanut cultivars (Gazipaşa, Florispan, and NC-7) and the local cultivar. It was determined that the planting date had a statistically significant effect on pod yield, days to maturity, days to 50% flowering date, number of pods per plant, plant height, shelling percentages, pod yield per plant, and 100seed weight. The results showed that the suitable planting date was 20 May and the Gazipaşa and local cultivars were promising for Aydın conditions. Peanut growth is affected by planting date in semi-arid regions, such as Aydın, where high temperatures and drought stress occur during late crop development and maturation periods.

Farklı Ekim Zamanlarının Verim ve Verim Unsurlarına Etkisi Özet: Adnan Menderes Üniversitesi Ziraat Fakültesi Tarla Bitkileri bölümü deneme arazisinde 4 yerfıstığı çeşidi, 4 farklı zamanda ekim yapılmıştır. Ekim zamanının verimi etkileyen bazı morfolojik ve agronomik özelliklere etkisini belirlemek amacıyla, Aydın iline en uygun ekim zamanının ve çeşidi tespit etmek için yapılan bu çalışma, bölünmüş parseller deneme deseni ile üç tekrarlamalı olarak 2004 ve .
