“…It is observed that while the researches related to yield and facilitating selection studies were carried out intensely un-til 1999, they decreased from 2000 and onward. It is known that earliness in maturity has increased and maturity periods are reduced due to the effects of phenological deviations resulting from global climate change, which has accelerated recently (Penuelas and Filella 2001;Walther et al, 2002;Craufurd and Wheeler, 2009;Visser et al, 2010;Sayılğan, 2016;Yavaş and Ünay, 2018;Gülser et al, 2019). In order to develop varieties with high adaptation to these conditions, revealing the effects of phenological features and new developments in plant morphology on yield is important in terms of the success of the breeding programs and prospective predictability.…”

In this study, the relationships between grain yield and yield characteristics were analyzed by running correlation and linear regression analyses. In the study, the herbal properties of 18 registered chickpea varieties and 3 local chickpea lines were used. The trials were continued for two years in two locations in the transitional zone of the Antalya-Korkuteli-Ulucak village and the coastal conditions of Antalya Aksu in the western Mediterranean region. According to the results of correlation and regression analysis, significant correlations were found between the yield and the number of the days to 50% emergence (r = -0.6707 and p<0.01), the number of days to 50% flowering (r = -0.6446 and p<0.01), number of days to maturity (r = -0.7303 and p<0.01), plant height (r = 0.4304 and p<0.01), first pod height (r = 0.5990 and p<0.01), number of pods per plant (r = -0.1681 and p<0.05) and the number of seeds per pod (r = 0.2696 and p<0.01). Although the data obtained as a result of the regression analysis did not exactly match the data determined, it was determined that close or average values could be reached, which may be beneficial for breeding activities.

“…The implications of increasing volumetric heat capacity in the soils under different land use types showed there is a positive correlation between volumetric water content and volumetric heat capacity. Gülser et al (2019) showed that volumetric heat capacity increased from 0.497 cal cm -3 °C to 0.541 cal cm -3 °C by increasing volumetric water content from 0.286 cm 3 cm -3 to 0.330 cm 3 cm -3 . The higher volumetric heat capacity of the soil under continuously cultivated soil and forest land is probably due to adsorption of water (from soil moisture content) forming thick hulls around the soil particles, which greatly enhanced its effective heat capacity (Abu-Hamdeh, 2003).…”

Article InfoAn in-depth knowledge on variations in soil heat transfer under different land uses is essential for proper understanding of the variations in thermal energy transfer under different human activities and modifications on land. This paper presents an investigation on the variations in soil heat transfer under different land use types in Abia State. This study evaluates three land use types: forest land (FL), continuously cultivated land (CC) and excavation site (EX). The parameters investigated in this study include; particle size distribution, bulk density, volumetric moisture content, atmospheric temperature, soil temperature, soil thermal conductivity, soil heat flux, soil volumetric heat capacity and soil thermal diffusivity. The results show that the different land use types studied influenced the soil heat energy transfer and had a significant effect on soil thermal properties. The results revealed that excavation site recorded the highest soil bulk density (1.70 Mg m -3 ) and soil temperature (42.6 o C) while forest land recorded the lowest bulk density (1.36 Mg m -3 ) and soil temperature (30.3 o C). The transmission of heat through a unit length of soil per unit cross-sectional area (2.476 W mk -1 ) was higher in forest land than the other land use types studied. Soil under continuously cultivated land recorded the highest volumetric heat capacity (1.407 J (m 3 K) -1 ). This study will help farmers and land owners in terms of choice and management of different land use types for agricultural and industrial purposes.

Toprakta sıcaklık alanının oluşumu ve ısı transferinin gerçekleşmesi toprakların ısısal özelliklerinin değişimi ile ilişkili olmaktadır. Isısal özellikler iklim faktörlerine ve toprak özelliklerine bağlı olarak değişmektedir. Bu araştırmada topraklarının hacimsel ısı kapasitesi, ısısal yayınım ve ısı iletkenliği katsayıları gibi ısısal özellikleri ile deneysel olarak daha kolay belirlenebilen bazı fiziksel ve kimyasal toprak özellikleri (EC, OM, Kil, Silt, Kum, HA, θ) arasında regresyon modeller oluşturulmuştur. Toprakların hacimsel ısı kapasitesiyle EC, OM, kil, silt, kum ve HA özellikleri arasında yapılan regresyon modelinin istatistiksel anlamlılık düzeyi (p=0.001) ve regresyon katsayısı (R 2 =0.76) yüksek olarak belirlenmiştir. Bağımsız değişkenlere hacimsel nem içeriğinin ( θ ) eklenmesi modellerin performasını (R 2 =0.77-0.99) yükseltmiş; θ, EC, OM, Kil, Silt, Kum, HA özelliklerini kapsayan regresyon modelinin istatistiksel anlamlılık düzeyi (p=0.000) ve regresyon katsayısı çok yüksek olarak saptanmıştır. Toprakların ısısal yayınım katsayısı ile EC, OM, Kil, Kum, Silt, HA, θ özellikleri arasındaki regresyon modelleri için R 2 =0.76 ve 0.79 (p=0.000 ve 0.002) olarak saptanmıştır. Regresyon modellerinin toprak özelliklerinin karesi, karekökü ve çarpımını kapsayan polinomlarla ifadesi modellerin performansını yükseltmiş; Kil, θ, Kil 2 , θ 2 , √OM (EC•HA), √Kil , OM, OM 2 , HA toprak özelliklerini içeren model yüksek düzeyde istatistiksel anlamlılık (p=0.001) göstermiş ve daha yüksek regresyon katsayısı (R 2 =0.90) ile karakterize edilmiştir. Isı iletkenliği katsayı ile Kil, Silt, Kum, HA, θ toprak özellikleri arasındaki regresyon modelinin performansı yüksek (R 2 =0.71; p=0.001); θ, Kum, Kil, Silt, HA, EC 2 , OM 2 , HA 2 , θ, EC, √OM, parametreleri arasındaki modelin performansı ise çok yüksek (R 2 = 0.91; p= 0.012) olarak belirlenmiştir. Elde edilen regresyon modellerin, toprakların ısısal özelliklerinin tahmin edilmesinde uygulanabilirliği mümkün gözükmektedir.
