In this study, it was determined that the varieties in lowland ecotype had low average seed yield, thousand-kernel weight and harvest index values, but the upland varieties had higher average seed yield and seed size and irrigation or water disability was effective factor on the parameters studied

📌 3 Key Takeaways

🎯
Objective & Hypothesis:Experiments were conducted for three years (2016, 2017 and 2018) under ecological conditions of Konya-Karapınar region of Turkey in randomized blocks in split plots experimental design with 3 replications.
📊
Key Findings & Data:Three irrigation treatments (S1: Full-irrigation with no water deficit, S2: 75% of S1 irrigation, S3: 50% of S1 irrigation) were placed into main plots and six switchgrass cultivars (Alamo, Kanlow, Shelter, Shawnee, Cave in rock ve Trailblazer) were placed into the subplots.

Abstract

Experiments were conducted for three years (2016, 2017 and 2018) under ecological conditions of Konya-Karapınar region of Turkey in randomized blocks in split plots experimental design with 3 replications. Three irrigation treatments (S1: Full-irrigation with no water deficit, S2: 75% of S1 irrigation, S3: 50% of S1 irrigation) were placed into main plots and six switchgrass cultivars (Alamo, Kanlow, Shelter, Shawnee, Cave in rock ve Trailblazer) were placed into the subplots. According to result of were obtained in terms of cultivars average seed yield were varied between 5.7 kg da-1 (Alamo) - 52.7 kg da-1 (Cave in rock), thousand-kernel weights between 0.82 g (Alamo) -1.66 g (Cave in rock) and harvest index between 0.21% (Alamo) – 3.57% (Cave in rock). In this study, it was determined that the varieties in lowland ecotype had low average seed yield, thousand-kernel weight and harvest index values, but the upland varieties had higher average seed yield and seed size and irrigation or water disability was effective factor on the parameters studied

Özet

Konya Karapınar koşullarında tesadüf bloklarında bölünmüş parseller deneme desenine göre, üç tekerrürlü olarak üç yıl (2016-2018 yılı) süreyle yürütülen bu çalışmada; ana parsel olarak üç sulama konusu (S1: Tam sulama, eksik nemin tarla kapasitesine getirilmesi; S2: S1’in % 75’ i kadar sulama; S3: S1’in % 50’ si kadar sulama) ve altı dallı darı çeşidi (Alamo, Kanlow, Shelter, Shawnee, Cave in rock ve Trailblazer) materyal olarak kullanılmıştır. Çalışmada su kısıtı bakımından ortalama birim alan tane verimi 15,4 kg/da (S3)-51,6 kg/da (S1) arasında, bin tane ağırlığı 1,22 g (S3)-1,41 g (S1) aralığında ve hasat indeksi 1,17 (S3)- 2,52 (S1) aralığında belirlenmiştir. Araştırmada çeşitler açısından ortalama birim alan tane verimi 5,7 kg/da (Alamo)-52,7 kg/da (Cave in rock) aralığında, bin tane ağırlığı 0,82 g (Alamo)-1,66 g (Cave in rock) aralığında ve hasat indeksi %0,21 (Alamo)- %3,57 (Cave in rock) aralığında belirlenmiştir. Çalışma ile ova (lowland) ekotipindeki çeşitlerin düşük birim alan tane verimi, bin tane ağırlığı ve hasat indeksi değerine sahip olduğu; yayla (upland) ekotipindeki çeşitlerin ise, birim alan tane verimi ve tane iriliğinin daha fazla olduğu ve sulamanın incelenen parametreler üzerinde etkili olduğu saptanmıştır.
