ABSTRACTMSc THESISTHE EFFECTS OF FERTILIZERS CONTAININGDIFFERENT MINERAL NUTRITIONS ON YIELD AND SOMEAGRICULTURAL CHARACTERISTICS IN MAIN CROPPEDPEANUTbrahim Halil ÖNCELERUNIVERSITY OF CUKUROVAINSTITUTE OF NATURAL AND APPLIED SCIENCEFIELD CROPS DEPARTMENTSupervisor: Prof.Dr. H.Halis ARIOĞLUYear: 2005, Page: 76Jury: Prof.Dr. H.Halis ARIOĞLUAssist.Prof.Dr. Sezer S NANAssist.Prof.Dr. Tahsin SÖĞÜTThis study was conducted at the experimental area of Field Crops Departmentin Agricultural Faculty of Çukurova University in 2004. The experiment wasdesigned as a randomized complete blocks with 3 replications under main cropconditions. The objective of this study is to determine the effects of differentingredients of fertilizers as basal fertilizer, which are Triple super phosphate,diammonium phosphate, 20.20.0, 15.15.15, and as top dressing, which are urea,ammonium nitrate, ammonium sulfate on agricultural characteristics of Osmaniye-2005 peanut variety. As a result of this study, due to the usage of fertilizers withdifferent ingredients, the yield of peanut changed between 5698-7025 kg/ha. Thehighest yield, which is 7029 kg/ha, was obtained as a result of 200 kg/ha Triple superphosphate + (200+290) kg/ha ammonium nitrate application, and followed by 6896kg/ha obtained from 200 kg/ha diammonium phosphate + 280 kg/ha ammoniumnitrate application. The lowest yield, which is 5698 kg/ha, was obtained as a result of200 kg/ha diammonium phosphate + 450 kg/ha ammonium sulfate application. Also,different ingredients of fertilizer applications were effective on 100 seed weight, 100pod weight, the yield per plant and the oil yield. However, no effects weredetermined in the other investigated characters.Key words: Peanut, Osmaniye-2005, Fertilizers have different ingredients, YieldII
