Tarımsal yetiştiricilikte artan su talepleri, günümüz gelişen ve teknolojilerini daha iyi sulama yönetimi stratejilerini geliştirmeyi zorunlu hale getirmiştir. Görüntüleme teknolojilerine dayalı bilgi üretimi de bu amaçlı kullanımlar içerisinde yer almaktadır. Bu çalışmada, İHA tabanlı multispektral görüntülerin yüzey altı ve yüzey üstü damla sulama uygulamalarının değerlendirilmesinde kullanılabilirliği araştırılmıştır. Bu amaçla ET0 (0.00, 0.25, 0.50, 0.75, 1.00, 1.25, 1.5) katları olacak şekilde programlanan bir slajlık mısır denemesinin büyüme sezonu boyunca insansız hava aracı kullanılarak görüntülenmiştir. Alınan görüntülerde 9 farklı vejetasyon indeksi oluşturularak uygulamaların izlenmesinde kullanılabilirlikleri birbirleri ile karşılaştırılmıştır. Yüzey altı damlama sulama yönteminde LCI ve TGI indeksleri, yüzey üstü damlama sulama yönteminde VARI indeksinin sulama programları düzeyinde kullanılabileceği belirlenmiştir (p<0.05). Gelişme dönemi boyunca temporal veriler incelendiğinde 9 bitki indeksi sonuçları arasında farklılıklar olduğu tespit edilmiştir (p<0.05). Multispektral görüntülerin analizinden türetilen yüzey ve yüzey altı damla sulama yöntemleri Vejetasyon İndeksleri (VI) ile karşılaştırıldığında işlemler arasında istatistiksel olarak anlamlı farklılık olduğu gözlemlenmiştir. Sulama oranları karşılaştırıldığında, bitki örtüsü indeksi değerlerinde de benzer farklılıklar belirlenmiştir. Elde edilen sonuçlar, farklı sulama uygulamalarına bitkilerin tepkilerini karakterize etmek için İHA entegrasyonlu multispektral görüntülerin uygulanabilirliğini göstermiştir. İHA’lar ile yapılan Akıllı Tarım, Hassas Tarım, Organik Tarım ve İyi Tarım Uygulamalarının çiftlik düzeyinde yüksek kullanım potansiyeline sahip olacağı düşünülmektedir.

Increasing water demands in agricultural cultivation have made it necessary to develop better irrigation management strategies within today's development and technologies. Information production based on imaging technologies is also included in these uses. In this study, the usability of UAV-based multispectral images in the evaluation of subsurface and surface drip irrigation applications was investigated. For this purpose, a silage maize trial programmed to be multiples of ET0 (0.00, 0.25, 0.50, 0.75, 1.00, 1.25, 1.5) was imaged using an unmanned aerial vehicle during the growing season. 9 different vegetation indexes were created in the images taken and their usability in monitoring the applications was compared with each other. It was determined that LCI and TGI indexes in subsurface drip irrigation method and VARI index in surface drip irrigation method can be used at the level of irrigation programs (p<0.05). When the temporal data were examined during the development period, it was determined that there were differences between the 9 plant index results (p<0.05). When the surface and subsurface drip irrigation methods derived from the analysis of multispectral images were compared with the Vegetation Indexes (VI), it was observed that there was a statistically significant difference between the treatments. When irrigation rates were compared, similar differences were determined in vegetation index values. The obtained results demonstrated the feasibility of UAV-integrated multispectral images to characterize the responses of plants to different irrigation applications. It is thought that Smart Agriculture, Precision Agriculture, Organic Agriculture, and Good Agricultural Practices made with UAVs will have high utilization potential at the farm level.
