Salih Eroğlu
Bu çalışmada çekirdekli ve çekirdeksiz nar taneleri (Punica granatum L.) ince tabaka halinde farklı sürelerde ultrason ön işlemi (US) uygulandıktan sonra 70 °C’de 1,3 m/s hava hızında kurutulmuştur. Nar tanelerinin kuruma kinetiğinin incelenmesi amacıyla literatürde çok kullanılan ancak karmaşık ve verilerin dönüştürülmesini gerektiren çok parametreli modeller yerine en çok iki parametreli modeller kullanılmıştır. Bu modeller Lewis (Newton), Page, Modifiye Page I, Weibull, Weibull I ve Modifiye Çift Terimli III modelleridir. Kurutma işlemlerini en iyi açıklayan modelin seçilmesi amacıyla hata kareleri ortalamasının kare kökü (RMSE) ve belirleme katsayısı (R2) değerleri incelenmiştir. Elde edilen sonuçlara göre çekirdekli nar tanelerinin kurutulmasını tüm işlem koşullarında en iyi Page modelinin açıkladığı belirlenmiştir. Çekirdeksiz nar tanelerinde ön işlemsiz ve 10 dakika US ön işlemli nar tanelerinin kurutulmasını en iyi açıklayan modelin Page modeli, 20 ve 30 dakika US ön işlemli nar tanelerinin kurutulmasını en iyi açıklayan modelin ise Weibull modeli olduğu belirlenmiştir. Bununla birlikte, kurutma öncesinde uygulanan farklı sürelerdeki US ön işlemlerinin çekirdekli ve çekirdeksiz nar tanelerinin kuruma sürelerini önemli ölçüde azalttığı belirlenmiştir.

Radish is a widely cultivated root crop susceptible to chemicals for its growth and development. The experiment was conducted to study the effect of different sources of organic fertilizers on growth and yield parameters in the Tokinashi variety of radish. The experiment was laid out using one factorial completely randomized block design with six treatments replicated four times. Vermicompost, goat manure, chemical fertilizers (NPK), poultry manure, farmyard manure and control were the applied treatments. Various growth and yield parameters of radish were measured and assessed at 15-day intervals. Various growth and yield parameters of radish were measured and assessed at 15-day intervals. Growth parameters were observed at 15, 30, 45, and 60 days after sowing. For yield parameters, destructive samples were taken and observed at 30 DAS and 45 DAS and harvested at 60 DAS. The assessments of plant growth and yield parameters showed that poultry manure (PM) treatments were superior. At the time of harvesting, the treatment comprising poultry manure had considerably greater plant height (30.55 cm), leaf length (29.44cm), leaf breadth (10.78cm), leaf number per plant (9.23), root diameter (10.33cm) and root length (20.16cm) with superior yield per ha (33.59 mt ha-1). Poultry manure significantly enhanced root yield and was positively correlated with all growth parameters. The highest benefit-cost (B: C) ratio was recorded in chemical fertilizer (3.99), which was statistically at par with poultry manure (3.81), suggesting that poultry manure might potentially replace chemical fertilizers for the Tokinashi variety of radish cultivation.

A survey was conducted in three selected kebeles of Kombolcha Regiopolitan City in South Wollo Zone. The selected kebeles were in proximity to brewery factory, Ethiopia. A semi-structured questionnaire was used to collect perception data from purposively selected three kebeles and a total of 57 randomly selected dairy farmers. Data collected were analyzed with a statistical package for social sciences (Version 20) and Microsoft Excel (2010). Smallholder dairy farmers had average herd size of 10.7 and 0.08 hectare total dairy farm per household. Average daily milk yield and lactation length of dairy cows was 10.8 liter/day and 9.5 months, respectively. The majority of farmers (59.6%) reared dairy cows with 50-75% exotic blood. The most smallholder dairy farmers satisfied their feed demand from the market and had a trend of providing both dense and poor quality affordable feed ingredients. Smallholder dairy farmers gave priority to feed different kind of cattle in the order of lactating cows, calve, pregnant, heifers and dry cows and used (100%) wet brewery spent grain as a source of dairy feed. Though, there was a brewery by-product supply deficit for half of year. The majority smallholder dairy farmers delivered brewery by-product directly from the brewery factories and followed by wholesalers and retailers. The majority of smallholder dairy farmers (96.4%) stated that the brewery spent grain was fed and stored freshly using different conservation techniques, and the remaining stored in ensiled (1.8%) and dried (1.8%) forms. Smallholder dairy farmers had no brewery spent grain ensiling practice and feeding brewery yeast to dairy animals. Smallholder dairy farmers indicated that high price due to abnormal market chain and shortage of brewery spent grain supply were the major challenges to sustain dairy industry in the study area, and the majority (40.6%) claimed to get swift solutions at high cost and less accessible brewery by-product.

Many allelopathic crops are cultivated in agricultural fields, and these plants can influence the growth of other plants in the cultivation environment with their phytotoxic compounds. One of these plants is the faba bean. In this study conducted under the ecological conditions of Sakarya/Arifiye, the allelopathic effects of Eresen-87, Salkim, Bilecik, and Sakarya faba bean genotypes on weeds such as Johnson grass (Sorghum halepense L.), curly dock (Rumex crispus L.), purslane (Portulaca oleracea L.), and wild mustard (Sinapis arvensis L.) were investigated. Weed seeds used in the experiment were collected from agricultural fields in the Sakarya province. Extracts from dried plant parts of faba bean genotypes were prepared and applied to petri dishes containing weed seeds at concentrations of 5% and 10%, with four replications. At the end of the research, it was observed that all faba bean genotypes at all application doses caused a decrease in germination rate (%), root length (cm), and shoot length (cm) parameters in the four weed species tested. The best results were determined as Eresen-87 and Bilecik at 10% concentration. When the activities of fresh and dry extracts of faba bean genotypes was compared, it was determined that dry application had a higher allelopathic effect.

Merve Bozdemir Akçil | Zeki Bayramoğlu
This study examines the problems arising from that the agricultural sector has become a significant employment area for migrant labor due to migrant migration. The presence of migrant labor in the agricultural sector has increased because of the cost advantages provided by agricultural operators of cheap labor supply despite informal working conditions. Migrant labor has crucial contributions to the sustainability of production activities, especially in the agricultural sector, where the local labor does not want to be employed. However, the perspective of local people toward migrants differs over time, especially due to different social and cultural characteristics. Since these differences are more noticeable in small settlements, such as rural areas people who are migrant to society or national identity become unwanted in the living spaces of local people over course of time, this study aimed to determine the perspective toward migrant labor and to evaluate the impact of this situation on the sustainability of production. In line with the results obtained, policy recommendations were made for the integration of migrant labor and the planning of agricultural activities.
