EGE BÖLGESİ MENEMEN YÖRESİ KOŞULLARINDA İKİNCİ ÜRÜN MELEZ MISIRIN EVAPOTRANSPİROMETRE TANKLARI İLE SU TÜKETİMİNİN ARAŞTIRILMASI

Menemen Yöresi'nde İkinci Ürün Melez Mısırın Evapotranspirometre Tankları ile Su Tüketiminin Araştırılması

Özet

Bu araştırmada P 3747 melez mısır ikinci ürün olarak ele alınmış ve aynıkoşullarında mevcut evapotranspirometrelere ekilmek suretiyle mısır bitkisiningünlük, aylık ve vejatasyon süresi içersinde net su tüketimi ile 1 kg kuru maddeoluşturabilmesi için harcadığı su miktarı araştırılmıştır.

Abstract

This research has been conducted in order to investigate the consumption of hybrid corn grown as a second by emplaying the evapotranspirometers with various ground water depths and the water consumed to assimilate 1 kg.dry matter and the effects of water consumption on the yield at the research facility of the culture technic department located at Menemen Faculty farm during the 1985-1986 years.A total of 12 transpirometre were used in the experiment each having 4 m2.Eight of them a 0.60 m. ground water depth; 2 of them have 0.90 m. Ground water depth and the remaining 2 have a 1.20 m.ground gater depth. The Daily water comsomption values of hybrid com were measured in mm.The following results were obtained from the research continued for 2 years.1- The grain yield per hectare in creased as the ground water depths increased but the vegetative part decreased.2- As the ground water depth increased the amound of water used for 1 kg.drymatter production also increased.3- The plant consumption values has decreased as the ground water depth increased.4- Under the similar soil and climaticalconditions when the irrigation depth of hybrid corn grown as a second the amount of irrigation water required was calculated as 352.6-521.0 mm.
