Twenty varieties of Musa the different genetic composition from Fedeplátano Germplasm Bank (AA, AAA, AAB, ABB, and AAAA AAAB) were characterized. Characterization includes physical properties such as weight, diameter, length, and dry matter percentage of fruit peel and functional properties of starches (pasting curves). The varieties Cachaco Pelipita, Fougamou, Kelong Mekintu and SH-3436-9 showed higher percentages of dry matter 35% indicating that these varieties would be of great importance for the sector fried and contain less water that the process be expedited increasing performance and decreasing absorption of oil. The varieties showed better behavior in relation to the properties of high viscosity, breakdown, ease of cooking and consistency were FHIA-23, Dwarf Banana, Banana Great Dwarf, Pompo Comino, indicating that these strains had great ability to withstand the retrogradation process and syneresis. | Se caracterizaron veinte variedades de musáceas de diferente composición genética del banco de germoplasma de Fedeplátano (AA, AAA, AAB, ABB, AAAA y AAAB). La caracterización incluyó propiedades físicas como peso, diámetro, longitud, materia seca y porcentaje de cáscara del fruto y propiedades funcionales de almidones (curvas de empastamiento). Las variedades Cachaco Pelipita, Fougamou, Kelong Mekintu y SH-3436-9 presentaron porcentajes de materia seca superiores al 35% lo cual indica que estas variedades serian de gran importancia para el sector de las frituras ya que al contener menos agua el proceso se agilizara incrementando el rendimiento y disminuyendo la absorción de aceite. Las variedades que presentaron mejores comportamientos frente a las propiedades de viscosidad máxima, breakdown, facilidad de cocción y consistencia fueron FHIA-23, Guineo Enano, Banano Gran Enano, Pompo Comino, lo cual indica que estas variedades tenían gran capacidad para resistir los procesos de retrogradación y la sinéresis.

Olukayode Adediran Okunade | Lisa Methven | Keshavan Niranjan
The effects of temperature and pressure processing on myrosinase extracted from fresh broccoli and brown mustard seed was studied. Brown mustard seeds had higher myrosinase activity (2.75 un/mL) than fresh broccoli (0.58 un/mL). The extent of enzyme inactivation increased with pressure (200-800 MPa) and temperature (30-80°C) for both brown mustard seeds and fresh broccoli myrosinase. However, at combinations of lower pressures (200-400 MPa) and temperatures (30-80°C), there was less myrosinase inactivation. When processing at a pressure of 300 MPa with a temperature of 70°C for 10 minutes, there was 65% myrosinase activity for brown mustard while at 300 MPa and 60°C, activity retention in fresh broccoli was 30%. Whereas, the corresponding activity retentions when applying only heat (70°C for 10 minutes) was 35% for brown mustard myrosinase, while there was no measurable myrosinase activity for fresh broccoli (60°C, 10 minutes). Thus, application of moderate pressures (200-400 MPa) on brown mustard and fresh broccoli can potentially be used to retain myrosinase activity needed for subsequent glucosinolate hydrolysis.

2020
Nuriye Meraklı | Abdulrezzak Memon
Plant growth-promoting rhizobacteria (PGPR) is a beneficial group of free-living soil bacteria that colonize the rhizosphere and are helpful in root growth and development. PGPR plays an important role in plant growth through the production of phytohormones, solubilization of inorganic phosphate, increased iron nutrition via iron-chelating siderophores and volatile compounds that affect the plant metabolism and signalling pathways. Additionally, PGPR shows synergistic and antagonistic interactions with rhizosphere microorganisms and soil which indirectly improve and enhance plant growth rate. Various environmental factors affect the PGPR growth and proliferation in the plants. There are several shortcomings and limitation in the PGPR research which can be addressed through the use of modern approaches and techniques by exploring multidisciplinary research which combines applications in microbiology, biotechnology, nanotechnology, agro-biotechnology, and chemical engineering. Furthermore, PGPR is also known to reduce the emission of greenhouse gases (GHGs), carbon footprint, and also increase the nutrient-use efficiency. Here we describe the importance of PGPR in sustainable agriculture and their role in plant growth and development.

Global urbanization and population growth obstruct the food waste management and cause uncontrolled accumulation of wastes. Ensuring the correct and efficient use and recycling of wastes having high protein content and generated throughout the food production and supply chain is becoming more important both in our country and all over the world. The evaluation of by-products released in the food industry is important for the development of new functional products and for greater economic rate of return on industrial scale. In this respect, bioactive peptides obtained from plant/animal wastes and rich in protein come into prominence. Bioactive peptides are also of great importance for human health because of their functional properties. In this review, functional properties of bioactive peptides obtained from protein-rich food wastes and their bioavailability mechanisms in human gastrointestinal system are discussed.

Büşra Ulu | Bahar Bayhan
The species of the Congridae family belonging to the Anguilliformes order are known as conger eel, and are morphologically similar to the eels which are among the species of the Anguillidae family. In both family species, the dorsal and anal fins are combined with the caudal fin. It is easily distinguished from eel species by the appearance of dorsal fin rays at a closer level to the head. There are 195 species belonging to 30 genus distributed in the world seas belonging to the Congridae family. A third genus of 3 species [Ariosoma balearicum (Delaroche, 1809), Gnathophis mystax (Delaroche, 1809) and Conger conger (Linnaeus, 1758)] shows the distribution of Turkish seas. While the first two species have distributed only Turkey's Aegean and Mediterranean seas, C. conger shows the distribution of all our seas. In this review, where morphological and biological characteristics of European conger are distributed in our country, all studies carried out both in our country and abroad are examined in detail and presented together. With this compilation study, especially biological information about species is missing in our country and attention has been made to contribute to the literature.

Ayşe Esra Peker
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 this study, the Brown Layer Pure Line that housing as individual cage system at the Poultry Research Institute in Ankara was used. Eggs obtained from 24, 28, 32, 36 and 40 weeks old eggs were collected 3 times a day in the morning (10:00), noon (12:00) and evening (15:00). On a total of 427 eggs; Shape Index (SI), Egg weight (YA, g), Albumen height (AY, mm), Roche scale (RS), Haugh unit (HB), Egg Quality Classes (YKS), Shell strength (KM, N) and Shell thickness (KK, Micron) features are emphasized and colour parameters (L*, a*, b*, Hue, Ch and ΔE) of egg shell were determined. The effect of oviposition time was found significant on the Shape index, Egg weight (g), Haugh unit and Shell thickness (micron) values. However, Albumen height (mm), Egg Quality, Roche scale and Shell strength (N) were not affected by oviposition time. Among the egg shell colour parameters, a*, b*, Hue and Chrome values were affected by the oviposition time, and the calculated difference was found to be statistically significant.

Sarria B., Doris E. | Vera, Raul R.
The development of early-weaned calves (three months old) in Andropogon gayanus, A. gayanus, Centrosema acutifolium and A. gayanus + Pueraria phaseoloides was investigated. Ten animals were used per treatment; the experiment beginning at the start of the rainy season. In this year 100 % and 45 % more rain fell in may and june respectively than the yearly average for these months. Several subjective comparison were made between the calves in the improved and group maintaned with their mothers in the native savannah until traditional early weaning occurs. The abnormally high rain-fall adverselty affected pasture recovery to the extent that it was impossible to make comparisons between the three pasture treatments. In general, however, all early-weaned calves did not perform as well as those remaining with their mothers. Results from the group in the pure stand of A. gayanus were the worst overall (live weight gains, protein and minerals in serum red blood cell), with three animals dying during the course of the trial. Early-weaning reduced anestrum pospartum and improved weight recovery of the cows. | Se midió el desarrollo corporal de terneros destetados a los tres meses de edad en pasturas de Andropogon gayanus, A. gayanus + Centrosema acutifolium y A. gayanus + Pueraria phaseoloides. Se utilizaron 10 terneros/tratamiento (70.3 ± 1.73 kg). El ensayo empezó en plena temporada de lluvias, que en este año fueron excesivas y afectaron negativamente la recuperación de las praderas. El desarrollo de los animales se redujo seriamente por la falta de forraje. Se hicieron algunas comparaciones subjetivas con un grupo de terneros que permaneció con sus madres en sabana nativa, hasta los nueve meses de edad, en la cual se realiza el destete tradicional. La cantidad de lluvia no permitió hacer comparaciones entre las pasturas. Los terneros destetados precozmente mostraron un desempeño muy pobre con respecto a los que permanecieron con sus madres; sin embargo, el grupo que pastoreó A. gayanus presentó los peores resultados en ganancia de peso vivo, porcentaje de proteína y minerales en suero, hematocrito, etc., muriendo tres animales por efecto del tratamiento. El destete precoz redujo el anestro posparto de las vacas y mejoró la recuperación de peso de las mismas.

Bu araştırma, farklı azot kaynakları ile yapılan ilave yaprak gübrelemesinin marul (Lactuca sativa L.)’da verim ve nitrat birikimi üzerine etkisini belirlemek amacı ile tarla koşullarında yürütülmüştür. Bitkisel materyal olarak bir adet yaz sıcaklarına dayanıklı kıvırcık marul (cv. ‘Bohemia F1’) çeşidi, yaprak uygulaması olarak da üre (CO(NH2)2), potasyum nitrat (KNO3) ve kalsiyum nitrat (Ca(NO3)2)’ın %0,4, %0,6 ve %0,8’lik dozları kullanılarak yaprak gübrelemesi yapılmıştır. Yaprakta toplam azot değerleri %2,20 (KNO3 %0.4) ile %3,00 (Üre %0,8) arasında değişmiştir. En yüksek nitrat birikimi 2610 mg kg-1 ile Ca(NO3)2’ın %0,8’lik uygulamasında belirlenirken, en düşük nitrat birikimi ise 2070 mg kg-1 ile sadece taban gübrelemesi (NH4NO3) yapılan parselde tespit edilmiştir. Farklı azot kaynakları ile yapılan ilave yaprak gübrelemesi sonucunda marulda en yüksek verim değerleri sırasıyla 4926 kg da-1 (Üre %0,6), 4787 kg da-1 (Üre %0,8) ve 4719 kg da-1 (Ca(NO3)2 %0,6) olarak tespit edilmiştir. Ancak, diğer girdilerin eşit olduğu araştırmada; gübre masraflarını dikkate alındığında karlılık analizinde ilk üç sıra diğer gübrelere göre düşük maliyetinden dolayı, ürenin farklı dozları ile yapılan ilave yaprak gübrelemesinde tespit edilmiştir. Araştırma sonuçlarına göre; karlılık oranları da göz önüne alındığında üre (%0,6) ile yapılan uygulamaların hem yüksek verim hem de yüksek kar elde etmek için daha uygun ve önerilebilir ilave yaprak gübrelemesi olduğu açık bir şekilde söylenebilir.

Economic literature pays a great deal of attention to economic and financial efficiency, expressed in terms of competition, concentration, productivity and profitability. This paper provides an all-embracing framework for the various existing theories in this area and illustrates these theories with practical applications. Currently, changing the size of the production potential in agricultural units in the Republic of Moldova depends to a great extent on the influence of different trends in the modification of production resources: the reduction of labor resources and agricultural land, quantitative and qualitative changes in fixed assets, and in current assets, etc. The notion of resource potential means the totality of the volume of all resources (natural, labor, material, intellectual, information, etc.) on specific enterprises, territories, branches, regions. Evaluating a broad field of research, the paper describes profit maximizing food products and demonstrates how several widely-used products can be fit into this framework. The authors also present an overview of the current major trends in the food sector and relate them to the assumptions for food products, thereby displaying their relevance and timeliness. The results include a set of recommendations for future research on this topic. The design, methodology and approach of this research is to explain why efficiency can help obtain a profit surplus, and to measure this efficiency. For quality of methodology we apply a range of statistical methods, as well as the strategic capability of organisations – made up of resources and competences. One way to approach the stategic capability of an organisation is to consider its strengths and weaknesses (for example, where it has a competitive advantage, profit, efficiency or disadvantage). Based on our research and results, we sought to understand the concepts of financial effciency and to apply these concepts to practical situations. At the start of each analysis entrepreneurship plays an important role. Most organisations have to innovate constantly to obtain profit and efficiency for food products. They need to be first into a market, or simply a follower of customers in developing new products and services.
