Star Ruby is the main grapefruit (Citrus paradisi) variety grown in Turkey; however, small fruit size is a common problem in ‘Star Ruby’ grapefruit. Fruit size is a decisive external quality parameter in citrus at the marketing of fresh citrus fruits. Fruit size can be enhanced by several techniques such as girdling and thinning. Various plant growth regulators are known to affect the growth and size of citrus fruit. The objective of the present study was to observe the effects of 2,4 dichlorophenoxypropionic acid-p (2,4-DP-P) on the fruit size, yield and quality of Star Ruby from 20-year-old trees budded on sour orange rootstock in Adana, Turkey in 2007. Four concentrations (50, 100, 150 and 300 ppm) of 2,4-DP-P were applied 8 weeks after anthesis during physiological fruit drop when the mean fruit diameter was 13-15 mm. The results indicated that the application of 2,4-DP-P increased the fruit size of Star Ruby grapefruit without reducing yield. The application had a significant effect on fruit yield except for trees treated with 50 ppm 2,4-DP-P. Compared with the control trees, applications of 2,4-DP-P increased the number of large, commercially valuable Star Ruby (>93 mm, 89-93 mm and 84-89 mm). No effects were determined on fruit internal quality parameters. Thus, the results of the present study revealed that 2,4-DP-P can be used to improve the fruit size of Star Ruby fruitlets during the June drop.

Nano Alemu Daba | Eba Muluneh Sorecha
Lentil crop has largely been affected by global climate changing, particularly, due to rainfall and temperature changing and variability. Hence, the experiment was conducted in Central Highlands of Ethiopia, namely Akaki, Chefe Donsa and Bishoftu Agricultural Research Centre, in the 2009 and 2010 cropping seasons to assess the genotypic variation of lentil for growth and yield performances. Five lentil genotypes viz. 87S-93549 X EL-103-16, 87S-93549 X EL-103-9-1, Alemaya X FLIP 88-41L-02-AK-14, Alemaya X FLIP 88-41L-02-AK-6 were arranged in randomized complete block design with four replications at all locations. The result of study revealed that the genotype 87S-93549 X EL-103-9-1 produced the highest seed yield of 1985.90 and 2500.00 kg ha-1 during 2009 and 2010 cropping seasons, respectively, at Akaki. On the other hand, the genotype Alemaya X FLIP 88-41L-02-AK-14 gave the highest seed yield (4189.1 kg ha-1) at Chefe Donsa in 2009 cropping season. The genotype X FLIP 88-41L-02-AK-14 was found to be the earliest in physiological maturity, accounting 128.75 days, and the genotype 87S-93549 X EL-103-9-1 had yield advantage of 27.6% over the local check at Chefe Donsa in the 2010 cropping season. Generally, all lentil genotypes were performed better at Chefe Donsa, followed by at Akaki and Bishoftu locations during both cropping seasons. Rainfall and temperature conditions have enormous influences on the growth and yields performances of lentil genotypes at all research locations. The study inspires other studies to be conducted on other factors than climate events thwarting the production of lentil crops in the study areas.

The purpose of this study was to measure and analyse the economic efficiency, and to identify the main factor behind economic efficiency of sorghum and millet for small scale farmers in traditional rainfed sector in North Kordofan State. Primary data is collected using structured questionnaire for a sample of 205 farmers from four localities namely (Sheikan, Umrwaba, Elnuhoud, and Elkhowi). Stochastic frontier approach (cost function) was used to analyse economic efficiency and descriptive statistics were used to analyse socio-economic characteristics of farmers. The results of stochastic frontier cost function revealed that the estimated economic efficiency of the sorghum and millet farmers obtained was found the mean economic efficiency to be 39% and 15%, respectively. The economic efficiency is very weak, because most parameters and inefficiency effect factor found to be not significant, these determinants may give a clear picture of farmers that could be targeted in order to increase efficiency

2018
Shemelis Kebede Hundie
Policy makers need to know the relationship among energy use, economic growth and environmental quality in order to formulate rigorous policy for economic growth and environmental sustainability. This study analyzes the nexus among energy consumption, affluence, financial development, trade openness, urbanization, population and CO2 emissions in Ethiopia using data from 1970–2014. The ARDL cointegration results show that cointegration exists among the variables. Energy consumption, population, trade openness and economic growth have positive impact on CO2 in the long-run while economic growth squared reduces CO2 emissions which confirms that the EKC hypothesis holds in Ethiopia. In the short-run urbanization and energy consumption intensify environmental degradation. Toda-Yamamoto granger causality results indicate the bi-directional causality between energy consumption and CO2 emissions, CO2 emissions and urbanization. Financial development, population and urbanization cause economic growth while economic growth causes CO2 emissions. Causality runs from energy consumption to financial development, urbanization and population which in turn cause economic growth. From the result, CO2 emissions extenuation policy in Ethiopia should focus on environmentally friendly growth, enhancing consumption of cleaner energy, incorporating the impact of population, urbanization, trade and financial development.

İrem Pekgöz | Fatih Mehmet Tok
Hatay iline bağlı kayısı alanlarında ve ev bahçelerinde 2014 yılı yaz aylarında arazi çalışmaları gerçekleştirilmiştir. Arazi çalışmaları sırasında sararma, solgunluk ve kök çürüklüğü gibi belirtiler gösteren kayısı bitkilerinden örnekler alınmıştır. Hastalıklı bitki dokuları yüzeyden dezenfekte edildikten sonra içinde tetrasiklin bulunan PDA ortamına ekilmiştir. Beş günlük inkübasyonun ardından, gelişen fungal koloniler mikroskobik ve makroskobik özelliklerine göre teşhis edilmiştir. Toplam 30 izolat Macrophomina phaseolina olarak teşhis edilmiştir. Tüm izolatlar tek mikrosklerot ya da hif ucu yöntemleri ile saflaştırılmış ve +6°C’de saklanmıştır. Her bir izolattan 10mm çapında diskler alınarak PDA ortamına transfer edilmiş ve 15, 20, 25 ve 30, 35 ve 40°C sıcaklıklarda gelişmeye bırakılmıştır. Optimum gelişme sıcaklığı 25 ve 30°C olarak tespit edilmiştir. Klorat fenotiplerini belirlemek amacıyla tüm izolatlar 120mM potasyum klorat içeren minimal ortamlarda geliştirilmiş ve sonuçta 30 izolatın 21’i sıkı, 6’sı parçalı ve 3’ü ise sınırlı gelişim göstermiştir. Lokasyon ile fenotip arasında herhangi bir ilişkiye rastlanmamıştır. Patojenisite testinde, tüm izolatlar kayısı, yerfıstığı, soya, mısır ve kavun bitkilerine inokule edilmiş ve 21 günlük inkübasyon süresinin ardından hastalık şiddeti 0-4 skalası kullanılarak belirlenmiştir. Hastalık şiddeti en yüksek 3,87 ile kayısı bitkilerinde oluşurken, yerfıstığı, soya, mısır ve kavun fidelerinde orta düzeyde hastalık şiddetinin oluştuğu ve aralarında istatistiksel olarak bir farkın olmadığı tespit edilmiştir. Moleküler çalışmalarda 14 farklı RAPD primeri kullanılmış olup, agaroz jel üzerinde oluşan 51 bandın 14’ü polimorfik olarak bulunmuştur. Filogenetik ağaç üzerinde 2 temel grup gözlenirken, bu iki grupta pek çok alt grubun oluştuğu gözlenmiştir. Oluşan gruplar ile lokasyonlar, sıcaklık tepkileri, klorat fenotipleri ve patojenisiteleri arasında herhangi bir ilişkinin bulunmadığı tespit edilmiştir.
