Bu makalede, bitki su durumunu ölçen yöntemlerden sulama programlaması amacıyla tarla koşullarına uygun olabileceklerin açıklanması amaçlanmıştır.
Bitkisel süreçler doğrudan bitki içindeki su koşulları tarafından belirlendiğinden, bitkinin içsel su durumunu esas alan sulama ölçütleri yersel koşullardan daha az etkilenirler ve daha yaygın bir kullanılabilirlikleri vardır.
Bitki su dengesine ilişkin çalışmalardaki yaklaşımlar özetlenmiş ve sulama programlamasındaki yararlılıkları değerlendirilmiştir. Bu yöntemlerden psikrometrik, basınç odacığı, oransal su içeriği, beta ışını ölçümü, infrared termometre ile uzaktan algılama yöntemleri incelenmiştir.

Evaluation of the Methods Based on Measurements of Internal Water Status for the Development of Irrigation Programs

Öz

The purpose of this article was to describe some of the techniques for measuring plant water status which are suitable for using at field conditions for irrigation programming.
Since plant processes are determinated directly by internal water status within the plant, irrigation criteria based on plant water should be less influenced by local conditions and should have nearly common application.
Approaches to studying plant water balance were summarized and their usefulness were evaluated for irrigation programing. These include psychrometric, pressure chaoter, beta-ray gauging, relative water content methods and remote sensing with an infrared thermometer.
