Bu çalışmanın amacı, buğdayın ZD 3.0 (sapa kalkma başlangıcı) döneminde klorofil metre (SPAD) ve GreenSeeker (NDVI) optik sensörler ile buğdayın N alımı ile tane verimi arasındaki ilişkileri ölçmek, doğrulamak ve gübre tavsiyeleri için denklem oluşturmaktır. Bu çalışmada, kuru koşullarda 4 farklı çeşit (Altay2000, Gerek79, Sönmez2001 ve Bezostaja1), 6 farklı azot dozuna (0, 3, 6, 9, 12 ve 15 kg N da-1) karşılık olarak verdikleri mevsim içi spektral yansıma okumalarından hesaplanan vejetasyon indeksleri ve mevsim içi verim tahmini yöntemiyle belirlenmiştir. Zadoks (ZD) 2.4 (kardeşlenme), ZD 3.0 (sapa kalkma başlangıcı), ZD 3.1 (sapa kalkma 1 boğum dönemi) ve ZD 3.2 (sapa kalkma 2 boğumlu dönem) olmak üzere 4 ayrı dönemde vejetasyon indeksi (NDVI) okumaları yapılmıştır. Bu dönemlerden en uygun Zadoks 3.0 (sapa kalkma başlangıcı) döneminde yapılan okumalar en gerçekçi yaklaşım olarak değerlendirilmiştir. Yaprak klorofil değerleri hakkında da bilgi veren spadmetre (SPAD) kullanımına göre mevsimiçi verim tahmini yapmaya olanak sağlayan NDVI yöntemi daha uygun bulunmuştur. 8 çiftçi tarlasından alınan değerlerin karşılaştırılmasında, optik sensör (NDVI) yönteminin önerdiği azot dozlarının çiftçi uygulamasıyla benzer verim düzeylerinde 0.9 kg N da-1 daha az azot kullanım sağladığı görülmüş, yani sistemin ekonomik etkinlik yönü öne çıkmıştır. Spadmetre kullanılarak erken ilkbahar döneminde azotlu gübre tavsiyesinde, normalize edilmiş spad (NSPAD) değerlerindeki artışın verimde neden olduğu artışı gösteren 4 dönemde de aynı Klorofil Yeterlilik İndeksi (Chlorophyll Sufficiency Index) 0.95 kritik eşik değeri nin altında olduğu zaman azotlu gübre tavsiye önerilmiştir.

This study aimed to determine the Wheat response to nitrogen topdressing doses and calibrate the optic sensör NDVI reading. The objective of this study was to quantify and validate the relationships between N uptake and grain yield of wheat using in-season measurements by chlorophyll meter and GreenSeeker optical sensor at Zadoks3.0 growth stage (stem elongation) of wheat. In the study, responses of four winter wheat cultivars (Altay2000,Gerek79,Sönmez2001 and Bezostaja1) to six N rate (0,3,6,9,12 and 15 kgNda-1) under rainfed conditions were compared with vegetation indices based on spectral reflection and In-Season Estimates of Yield calculated from these indices. GreenSeekersensor was used for this purpose. Vegetation indices (NDVI) were obtained at growth stages Zadoks2.4, Zadoks3.0, Zadoks3.1 and Zadoks3.2, Zadoks3.0 (stem elongation) was found to be the most realistic reading time. In the last year of the project NDVI based calibration equations were preferred for tests in actual farmers’ fields due to the fact that NDVI method had an advantage, over Spadmeter (SPAD) use, of giving information on biomass, in addition to nitrogen nutrition status of the crop, making in-season yield estimation possible. A comparison of the system with traditional farmer applications, based on the average of 8 farmers’ fields, the new system was shown to give similar yields with 0.9 kg da-1 less Nitrogen in the spring (ZD3.0), showing its economically promising value. Chlorophyll Sufficiency Index was determined by using spadmeter in the early spring nitrogen fertilizer recommendation in the same period as 0.95 critical threshold value which showed increase in yield caused by increase in NSPAD values.
