Field experiment was conducted to determine the effect of prilled urea (PU) and urea super granule (USG) with their different nitrogen levels (N1 : 70, N2 : 100 and N3 : 130% of the recommended dose) on rice and NH4+-N/NO3- -N in post-harvest soil. Experiment was laid out in a randomized completely block design with three replications at Bangladesh Institute of Nuclear Agriculture (BINA) Farm, Mymensingh, Bangladesh during 2015-16. Higher yield attributing characters (plant height, effective tiller panicle-1, panicle length were achieved from USG × N2 treatment. USG, N2 (100% N) and USG × N2 produced the highest grain (3.60, 3.64, 3.78 t ha-1) and straw yield (3.55, 3.45, 3.70 t ha-1) respectively. Though USG × N3 treatment produced the highest effective tiller, panicle length and unfilled grain but USG × N2 treatment produced maximum grain yield of rice due to higher filled grain. In respect of mineral nitrogen, NH4+-N was decreased with the increase in soil depth but opposite result was found in NO3- -N in soil. Deep placement of USG fertilizer released NH4+-N slowly and steadily compared to prilled urea in soil. As a result, one time fertilizer application of USG is better than three times broadcast application of PU in terms of crop yield, nitrogen status in different depth of soil and labour cost. Future research needs to develop the effective USG fertilizer applicator for deep placement in soil during crop production.

Bark beetles (Coleoptera: Curculionidae) are among the important pests of forest in the world and in Turkey. Pine-feeding bark beetles interact chemically with their host tree via the behavioral, physiological, and biochemical effects of one class of monoterpenes. The half of oleoresin producing by trees such as pines, spruces, firs in the forests is the monoterpene. The monoterpenes occur in the oleoresin and function as behaviorally active kairomones for pine bark beetles and their predators, presenting a classic example of tritrophic chemical communication. The monoterpenes are aggregation pheromones for pine bark beetle. In the control of bark beetles, monoterpenes are used in traps. For example, the monoterpenes are an attractant for bark beetles. Also, Myrcene is used for a synergistic effect in the trap. Monoterpenes can toxic to insects. Limonene is among the most toxic monoterpenes to bark beetles. Also, the interaction is found between monoterpenes and prey of bark beetle. Monoterpenes are enhanced to respond of predatory to the pheromone of bark beetle.

Günümüz koşullarında, hayvancılık işletmelerinin ve işletmecilerin karşılaştığı en büyük sorunlardan biri, işletme kapasitesini büyütmek için nitelikli ve güvenilir iş gücü temini ve bunun getirdiği maliyet sorunlarıdır. Buna paralel olarak yem hazırlama ve dağıtımı ile ilgili iş gücü, zaman ve maliyet sorunları da işletmeler için önem taşımaktadır. Hayvancılıkta yemleme işlemi günlük çalışmalar içerisinde önemli bir yer tutar. Kullanılan yem, bunun sevki ve idaresi hayvan sağlığını ve işletme verimini etkileyen en önemli faktörlerdendir. Bu çalışmada, durumun önemi göz önüne alındığında, yem hazırlama ve yem dağıtım ile ilgili iş gücü, zaman ve sürü yönetimi sorunları için çözüm olabilecek ve ülkemizde kullanımı yaygın olmayan ve henüz tanınmayan yemleme robotu hakkında operasyon bilgileri verilmiş, sürü yönetimi üzerine etkileri belirlenmiş ve geleneksel yem hazırlama ve dağıtma sistemleri ile karşılaştırılması sonucunda iş gücü ve zaman analizleri yapılmıştır. Özellikle yüksek kapasiteli işletmelerde, yemleme robotu aracılığıyla sağlanan otomasyonun klasik sistemler ile karşılaştırıldığında iş gücünden %75 oranında, zaman girdisi konusunda ise 13,75 kat tasarruf olanağı çıkan sonuçların en önemlilerindendir. Bunun yanı sıra modern işletmelerde kullanılan süt sağım robotu gibi diğer otomasyon içeren işler için de bir destek unsuru ve sürü yönetimi olarak bütünleyici bir etkisi olduğu çıkan diğer bir önemli sonuçtur.

Genetic improvement in components of economic importance along with maintaining a sufficient amount of variability is always the desired objective in the any maize (Zea mays L.) breeding program which will be handled under the conditions of Haramaya, Eastern Ethiopia. Therefore, an experiment was conducted using (27) and (3) check/control varieties to determine the genetic variability of maize genotypes at Haramaya, eastern Ethiopia. The study results revealed that significantly the tallest plant heights for (PH) were recorded from (3) (170 cm) and (18) (167.5 cm) genotypes whereas the shortest PH were recorded from (13) (117.5 cm) and (23) genotypes (120 cm). Good plant aspects (PA) were obtained from genotype 12, 22 and 26 (PA-1.5) and poor PA were attained from genotype 1 (PA-2.5). Besides, genetic and phenotypic variances were estimated for seven components. The highest genotypic coefficients variation (GCV) and phenotypic coefficients of variation (PCV) were calculated from grain yield (GY – 23.39%). Comparatively the higher GY were attained from the genotypes of 3, 9 and 12. It can be concluded that almost all components of the PCV are greater than the GCV. Superior selected genotypes are recommended to the researchers /breeders to develop disease resistant and high yielder varieties to increase maize production by farmers under Haramaya and other similar agroecologies.

That agricultural sector is examined closer from every point of view and is restructured in complied with the requirements of the age has to be structured comes to our face as a reality any longer accepted by every sector of the society. The various developments experienced in the world in the recent years have directly or indirectly affected agricultural sector. In the economy of Turkey, one of the countries attracting attention with its rapidly growing, there are many theoretical studies dealing with the direct or indirect contribution of agricultural sector. However, it is necessary to increase the number of the applied studies introducing the existing situation of the sector and enabling to develop the effective policies for the sector. For, it is highly important for the theories put forward in theoretical framework to be supported by empirical analyses in terms of forming effective policy suggestions. In the study, the three sub-sectors were considered such as the subsectors of cereal, legume, and fruit-vegetable and the existing situation of the sector was analyzed by moving from the macro variables. In order to identify the effects of macroeconomic variables (inflation, exchange rate, interest, monetary supply), selected in the direction of the aim of the study, panel cointegration test was utilized. Setting off from this point, when the analysis made in the study is examined for all sectors, it was identified that the variable affecting the sector the most was interest rate. When the results of panel cointegration test between interest rate and agricultural production were examined, while there was a negative directional relationship between the production of subsector “fruit vegetable” and the variable “interest” as expected, it attracts attention that there was a positive relationship between the subsector of cereal legume and interest in contrast to this.

In sub-Saharan Africa, multiple plant nutrients deficiency besides nitrogen (N) and phosphorus (P) is a major growth-limiting factor for crop production. As a result, some soils become non-responsive for Rhizobium inoculation besides P application. Based on the soil test result, the soil of Experimental sites had low organic matter (OM), nitrogen (N), phosphorus (P), sulphur (S) and zinc (Zn)[xy1]. Hence, an experiment was carried out on-farm at Gondar Zuria woreda in Tsion and Denzaz Kebeles to evaluate the effect of Rhizobium inoculation, S and Zn application on yield, nodulation, N and P uptake of chickpea. The experiment included twelve treatments developed via factorial combination of two level of inoculation (Rhizobium inoculated, un-inoculated), three level of S (0, 15, 30 kg Sulphur ha-1) and two levels of Zn (0, 1.5 kg Zinc ha-1). The treatment was laid out in randomized complete block design with three replications. Results showed that the highest mean nodule number (15.3) and nodule volume (1.3 ml plant-1) over locations were obtained with Rhizobium inoculation integrated with 15 kg S and 1.5 kg Zn ha-1 which resulted in 37.8% and 116.7% increment over the control check, respectively. It was also observed that combined application of Rhizobium and 30 kg S ha-1 caused the highest (6.7) mean nodulation rating and seed yield (1775.5 kg ha-1) over locations which resulted in 86.1% and 28 % increase over the control check, respectively. Moreover, this treatment improved P use efficiency of chickpea. On the bases of observed result, it can be concluded that the response of chickpea to Rhizobium and P application can be improved by S application and Rhizobium inoculation with application of 30 kg S ha-1 with recommended rate of P and starter N is recommended for chickpea production at the experimental locations in Gonder Zuria Woreda.

Consumer demands for raw or unprocessed foods increased due to consumers’ awareness of the importance of a healthy life. However, searching alternative techniques instead of heat treatment is an important issue for the industry in order to enhance the microbiological quality. Non-thermal techniques are encouraged because of their effectiveness on the preservation of natural aroma, flavor and microbiological quality without causing any change in the structure of the product. Plasma technology is one of these alternative techniques. Plasma technology, known as the fourth state of matter, is known as the partial ionization of positive and negative ions, free radicals, charged particles and molecules in electron and photon form. Plasma is usually forms or formed by electric or electrical discharge or by a strong radiation effect. Plasma is classified according to its temperature, thermal equilibrium, and pressure. Cold plasma technique is used in foods for contaminated surfaces and cleaning of medical instruments. In this review, plasma technology applied to foods and their effects are presented.

The aim of study is to investigate; the effect of increasing several doses P application on soil C, N and P concentration in Long term experiment conditions. Tested hypothesis; increasing P doses application increases soil C, N and P concentration, consequently plant yield can increase. The experiment has establish at University of Çukurova, Faculty of Agriculture, Research and Application field on Arık soil series from since 1998 until update. Four doses of P applied; such as 0 kg P2O5 ha-1 (P0), 50 kg P2O5 ha-1 (P50), 100 kg P2O5 ha-1 (P100) and 200 kg P2O5 ha-1 (P200) with tree replications. Under rain fed condition Adana-99 species wheat (‎Triticum aestivum L.) seeds were sown in November 2017 and harvested at May 2018. Soil samples were taken at different depth (0-15 cm and 15-30 cm) of rhizosphere and non-rhizosphere part at harvest. Soil P concentrations, organic C (OC), inorganic C (IC), soil total carbon C and N were analyzed. Result shown that there is a statistically difference as P concentration, especially in both depth of rhizosphere and non-rhizosphere soils, the best application is P200 compared to the control. As the P dose increased, also soil P content increased linearly. In terms of soil OC content, there was a statistically significant difference at a depth of 15-30 cm in rhizosphere and non-rhizosphere soils and, the best practice was got at P200 application compared to control treatment. In addition, due to increasing doses of P application, the mean soil OC, total N and C content increased. The founded results are support our hypothesis.

The world’s population is increasing day by day, and the need of the energy and food is increasing at the same rate. As it is known, facilities which engaged in agricultural activities take a large share of the world’s industrial pie, so the pollution sparked by the activities of these industries is also uncondescending. Energy production from organic wastes exposed as a result of agricultural activities is an important working area; damage to the environment will also be reduced by the recovery of the wastes. In this study, hydrogen gas production from organic wastes released by agricultural activities will be demonstrated. In addition, literature review on the state of hydrogen energy from organic wastes in the world and in Turkey will be carried out.
