Abstract:

 In our country, the analysis of factors affecting yield and harvest in agricultural production and the early prediction of these products are of great importance. Farmers in the Celikli basin generally use traditional methods and quantities for wheat production to increase yield. However, with the advancement of science and technology, it is necessary to analyze agricultural input uses with crop simulation models CSM in order to achieve high and quality yields. After the necessary evaluations, a series of adaptation and precautionary measures should be implemented. Different application methods in various times and amounts have also been tried from time to time to increase the yield of the wheat varieties grown in the Çelikli basin fields. The aim of our study was to evaluate canopy height, plant nitrogen content, evaporation and transpiration amounts, leaf area and harvest indices, biomass, and harvest weights according to 15 different sowing time ST applications with the Ekiz bread wheat variety. In the study, the effects of different wheat sowing dates EZ1October 7 Actual Sowing, EZ2October 21 15 days later, EZ3November 4 30 days later, EZ4November 18 45 days later, EZ5December 2 60 days later, EZ6December 16 75 days later on relevant yields and other outputs were evaluated. According to the results obtained from the study conducted in the Central Anatolia transition zone, the most suitable planting date among different planting dates was determined to be October, although it varies based on the product output. It is predicted that significant gains will be achieved in areas such as time, environment, and cost based on the modeling results.

 Ülkemizde yapılan tarımsal üretimlerde verim ve rekolteyi etkileyen faktörlerin analizi ve bu ürünlerin erken verim tahmini büyük önem arz etmektedir. Çelikli havzasındaki çiftçiler buğday üretimini artırmak amacıyla bakım yöntemlerini genellikle geleneksel metot ve miktarlar kullanarak sürdürmektedirler. Fakat, Gelişen bilim ve teknoloji ile birlikte çevreye duyarlı yüksek ve kaliteli verim elde edebilmek için bitki simülasyon modelleri BSM ile analizi mümkün hale getirmiştir. Gerekli değerlendirmeler sonrasında ise bir takım uyum ve önlem alma uygulamaları yapılmalıdır. Çelikli havzasındaki tarlalarda yetiştirilen buğday çeşitlerinin verimliliği artırmak için farklı zaman ve miktarlarda uygulama yöntemleri de zaman zaman denenmiştir. Çalışmamızın amacı, Ekiz ekmeklik buğday çeşidi ile 15 farklı Ekim Zamanı EZ uygulamalarına göre Kanopi yüksekliği, Bitki azot miktarı, Buharlaşma ve terleme miktarları, Yaprak alan ve Hasat indeksleri, Biyokütle ve Hasat ağırlıkları değerlendirilmiştir. Çalışmada, EZ17 Ekim Gerçek Ekim, EZ221 Ekim 15 gün sonrası, EZ34 Kasım 30 gün sonrası, EZ418 Kasım 45 gün sonrası, EZ52 Aralık 60 gün sonrası, EZ616 Aralık 75 gün sonrası gibi farklı buğday ekim etkisinin ilgili verim ve diğer çıktılara etkisi değerlendirilmiştir. İç anadolu geçit bölgesinde yürütülen ve elde edilen bu sonuçlara göre, Farklı ekim tarihleri arasında en uygun ekim tarihi ürün çıktısına göre değişmekle birlikte Ekim olarak belirlenmiştir. Modelleme sonuçlarına uygun değerlendirmeler zaman, çevre ve maliyet gibi konularda önemli kazanımlar elde edileceği öngörülmüştür.
