Özet:

 Precision agriculture PA includes advanced technologies to increase efficiency and profitability of agricultural operations from tillage to harvest and offers sustainability of the natural resources and the environment. Automatic steering AS is the mostly-used PA technology in the world and in Türkiye providing many benefits. It has potential for efficient and sustainable agronomic practices including soil ridge tillage and sowing. Adequate spacing is needed to provide equal living area for each plant in sowing. Thus, in mechanized planting, pass-to-pass plant inter-row spacing PIRS should be equal in parallel passes. Research on the benefits of the AS for providing uniform PIRS in sowing is very limited. This work aimed to appraise the pass-to-pass PIRS deviations in planting with GNSS-based AS with three signal correction sources RTK, CORS, SBAS and without AS manual steering for comparison. The data were obtained from 24 farmer fields cotton and corn with PIRS set values of 70-75 cm located in the Cukurova region of Türkiye. Pass-to-pass PIRS values were manually measured and the deviations from the set value were analyzed in terms of root mean square error RMSE. The mean PIRS variations in sowing by manual steering 7.4 cm were found as significantly higher than the AS based soil ridge tillage and  or sowing CORS: 5.0 cm, SBAS: 5.9 cm, RTK: 6.7 cm p0.05. In sum, it was found that the AS technology offers benefits in lowering the pass-to pass PIRS variations but the level of benefit changes from farmer to farmer; hence, the AS should be used cautiously with proper settings for greater benefits.

 Hassas tarım HT, toprak işlemeden hasada kadar tarımsal faaliyetlerin verimliliğini ve kârlılığını artırmayı, doğal kaynakların ve çevrenin korunmasını ve böylelikle sürdürülebilirliği hedefleyen ileri teknolojileri içerir. Otomatik dümenleme OD, dünyada ve Türkiyede en yaygın kullanılan ve birçok fayda sağlayan HT teknolojisidir. OD; sırta toprak işleme ve ekim dâhil olmak üzere tarımsal işlemlerde verimli ve sürdürülebilir uygulamalara imkân sağlar. Makinalı hassas ekimde, her bitkiye eşit yaşam alanı sağlamak için bitki sıra aralarında yeterli boşluk gereklidir. Bu nedenle makinalı ekimde paralel yan yana geçişlerde bitki sıra arası mesafesi BSAM eşit olmalıdır. Ekimde eşit BSAM sağlamak için ODnin faydalarına ilişkin yapılan araştırmalar oldukça sınırlıdır. Bu çalışma, üç farklı sinyal düzeltme kaynağı RTK, CORS, SBAS kullanan GNSS esaslı OD ile ekimde yan yana paralel geçişlerdeki PIRS sapmalarını karşılaştırmak amacıyla yapılmıştır. Çalışmada OD kullanılmayan manuel yönlendirmeli tarlalardaki BSAM değerleri de karşılaştırma amacıyla incelenmiştir. Veriler, Çukurova bölgesinde, sıra arası mesafe değerleri 70-75 cm olan 24 çiftçi tarlasından pamuk ve mısır elde edilmiştir. Paralel yan yana geçişlerdeki BSAM değerleri manuel olarak ölçülmüş ve ayarlanan değerden olan sapmalar hata kareler ortalamasının karekökü RMSE değeri ile analiz edilmiştir. Manuel dümenlemeli ekimde ortalama BSAM sapmaları 7.4 cm, OD ile yapılan sırta toprak işleme veveya ekime göre daha yüksek bulunmuştur CORS: 5.0 cm, SBAS: 5.9 cm, RTK: 6.7 cm p0.05. Özetle, OD teknolojisinin yan yana paralel geçişlerde BSAM değişimlerini azaltmada fayda sağladığı ancak fayda düzeyinin çiftçiden çiftçiye değiştiği belirlenmiştir. Bu nedenle, ileri düzeyde faydalar elde edebilmek için OD sistemleri uygun ayarlarla dikkatli bir şekilde kullanmalıdır.
