In this research, some physicochemical and microbiological characteristics and mineral compositions of marmalades produced by traditional method using Berberis integerrima Bunge (purple barberry), Berberis vulgaris L. (pink barberry), Rosa pimpinellifolia L. (black rosehip), Rosa canina L. (pink rosehip), Malus sylvestris Miller (sour apple), and Vaccinium corymbosum L. (blueberry) wild fruit naturally grown in Bayburt and Trabzon provinces were determined. As a result of the research; pH 2.56-4.18, titration acidity (in terms of citric acid) 0.62-3.40%, dry matter 53.65-64.90%, water soluble dry matter 52.28-64.53%, water activity 0.818-0.894 and HMF (5-hydroxymethyl-2-furfural) were detected in the range of 5.81-53.40 mg/kg. As a result of microbiological analysis, total aerobic mesophilic bacteria, coliform group bacteria and yeast-mold were not detected in any of the samples. In the marmalade samples, the macro minerals Ca, K, P and Mg are ranged from 23.56-425.12 mg/kg, 1275.74-5918.10 mg/kg, 21.98-921.26 mg/kg and 125.50-776.23 mg/kg, respectively. Of the micro-minerals Fe 4034.85-22346.74 µg/kg, Mn 531.63-15065.91 µg/kg, Zn 345.40-6250.76 µg/kg, B 2872.99-7300.37 µg/kg, and Ba were found between 689.31-6455.24 µg/kg. The results of heavy metal analysis showed that marmalade samples were within reliable limits. It is concluded that these fruits, which are not usually consumed as table, but have rich mineral composition, characteristic taste and pleasant aroma, can be evaluated in marmalade production. In the years when the yields of wild fruits are high, it can be processed into products with long shelf life such as jam and marmalade and converted into added value can contribute to the regional economy.

In this study, microbial transglutaminase (MTGase) enzyme was used to produce yogurt from camel milk. It was reported that camel milk is rich in antimicrobial substances such as lysozyme, lactoperoxidase, lactoferrin and immunoglobulins, which prevent the production of yogurt from camel milk. With the advances in enzymology, it has been suggested that using enzymatic modifications to improve the functional properties and nutritional value of proteins may be effective in the production of yogurt from camel milk. For this purpose, the protein content of camel milk was increased by 6.2% with the addition of sodium caseinate, whey protein concentrate and micellar casein powder. MTGase enzyme was used at concentrations of 3 U and 6 U and the enzyme and the starter culture were added into the camel milk at the same time after that it was left for fermentation. Viscosity, pH and titratable acidity (as lactic acid, %) analyses were performed every hour during fermentation. The increase in viscosity formed as a result of cross-linking with the addition of MTGase enzyme, and the cross-linking formed were determined by decreasing the monomer band intensity of protein fractions with SDS-PAGE. It was found that the higher the MTGase concentration the higher the crosslinking reactions between the amino acids and the higher was the relative viscosity. In addition, the number of yogurt bacteria was determined on both M17 agar and MRS agar to investigate whether yogurt bacteria grow in camel milk and whether their growth is affected by the MTGase enzyme. As a result of the analysis, it was determined that the addition of MTGase enzyme has no suppressive effect on the growth of bacteria.

In addition to the good adaptation of high temperatures and poor soils, cowpea (Vigna unguiculata L.) can be a good source of forage for livestock. This study was carried out to determine seed yield and some agronomical parameters of cowpea grown in different row spaces as double crop in Samsun ecological conditions. In the experiment, forage cowpea cultivar Ulkem and Line H-8 grown in four row spaces (20, 35, 50, 65 cm) in a Randomized Split Block Design with three replications. Seeds were sowed after harvesting wheat at July 13, 2017 and 15 July 2018. Seed harvest was made at October 20, 2017 and November 5, 2018. The results showed that seed yields ranged from 765 to 2178 kg ha-1 in 2017 and 397 to 1464 kg ha-1 in 2018. 1000 seed weight ranged from 161.17 to 183.93 g in 2017 and 146.40 to 160.90 g in 2018. In 2017 and 2018, mature pod ratio were 65.7 – 85.8, 30.0 – 60.3% respectively. Pod number per plant was between 5.66-15.00 pods/plant in 2017, 9.50-16.25 pods/plant in 2018. Seed number per pod was ranged from 8.80 to 12.43 seeds/pod in 2017, from 8.00 to 11.50 seeds/pod in 2018. Though the highest seed yields were obtained from 20 cm row space, it is risky cultivated cowpea for seed production as double crop in Samsun conditions because of earlier autumn rainfall and high humidity.

The field trials were conducted during the rainy and dry seasons of 2014 and 2015 to investigate the influence of population density and time of introduction of the component maize on the performance of garden egg/maize intercrop in Nigeria. The trial was laid as a randomised complete block design in a split-plot arrangement with 3 replications. The main plots were time of introduction of maize [2weeks before transplanting (WBT), same time with transplanting (STT) and 2 weeks after transplanting (WAT)] while 9 plant population ratios were the sub plots (100M: 100G, 100M: 75G, 100M: 50G, 100M: 25G 100M: 0, 0:100G, 25M: 100G, 50M: 100G, 75M: 100G). Intercropping system was evaluated using competitive indices and data collected on yield and yield components of both crops were subjected to analysis of variance. Maize sown STT garden egg had significantly high grain yield (3.70 t/ha) while the highest garden egg fruit yields of 40.96 t/ha was obtained when maize was introduced 2 WAT garden egg. This study recommends that, 50-75% maize should be introduced 2WAT of 100% garden egg during the dry season where irrigation facilities are available for optimal crops yields and minimal intercrop losses.

Peafowl is a common name of three species of the Phasianidae family. It is known as a sacred bird in many Asian countries and India that is the homeland of the peafowl. They live in groups and prefer cultivated areas and forests where they can find more food in nature. They feed on cereal grains, insects, fruits, leaves, seeds. It has a strong structure and adapts very well to different climates. Because of this feature can be produced anywhere in the world. There are commonly known three different types of peafowl. Blue (Indian) Peafowl (Pavo cristatus), Green Peafowl (Pavo muticus) and Congo Peafowl (Afropavo congoensis). The most recognizable species of them is the Indian Peafowl. Peafowl has always been the center of attention with its striking, bright and eye-catching colors on its body and long tail, and it is natural wonders. Therefore, they are especially indispensable members of zoos and ornamental gardens. Although peafowl are usually produced for their beautiful appearance, their meat is also very tasty and beneficial. This article is prepared to give brief information about peafowl.

Hibiscus sabdariffa L. (Hibiskus) is a plant that belongs to the Malvaceae family and and is a rich source of anthocyanins and other bioactive compounds. In this study, the total phenolic and flavonoid content, antioxidant and antimicrobial activities of commercially supplied Hibiscus sabdariffa calyx extracts obtained by two different extractors (soxhlete and ultrasonic bath) were investigated. In addition, fatty acids were analysed by GC-MS analysis, 14 different fatty acids were determined and the major fatty acid components of extracts obtained from plant calyxes were palmitic acid (15.25%) and oleic acid (32.18%) and linoleic acid (30.77%). The ultrasonic bath was found to be more effective to reveal the bioactive contents of the extracts than the soxhlete. Total phenolic content and flavonoid values of plant calyx extracts (USB) were 23.29 and 3.08 mg ml-1, respectively, and FRAP and IC50 (% DPPH) values were 47.54 µg g-1 and 0.61 mg ml-1, respectively. Antimicrobial activity experiment carried out with total of 9 microorganisms consisting of seven bacteria and two yeast showed that H. sabdariffa extracts had dose-depended inhibition on test microorganisms but S. cerevisia.

Iron (Fe) is an important trace mineral for plant development, and plants grown in Fe deficiency experience yield losses due to the leaf chlorosis. In addition to agronomic measures that can be taken to minimize these losses, new plant genotypes can be developed effectively through genetic engineering. While dicots such as Arabidopsis thaliana use a reduction-based strategy to uptake high amounts of iron from the rhizosphere, the chelation strategy has evolved in Gramineous plants including barley (Hordeum vulgare). In this study, barley NICOTIANAMINE SYNTHASE1 (HvNAS1) gene, which is responsible for the production of nicotianamine that can complex with iron, was cloned and expressed at a constitutive high level in Arabidopsis plants. The expression levels of Arabidopsis genes encoding for the proteins involved in iron uptake increased together with HvNAS1 in the T3 Arabidopsis plants. Moreover, the root lengths, root and stem fresh weights, ferric chelate reductase enzyme activities of the plants also increased in the transgenic Arabidopsis plants under Fe deficiency. In addition, significant increases in iron and zinc levels were determined in the roots and shoots of transgenic Arabidopsis plants. As a result, transgenic Arabidopsis plants overexpressing the barley HvNAS1 gene can take up more iron from the rhizosphere and carry this iron to the shoots. This study demonstrates the power of genetic engineering to develop Arabidopsis plants overexpressing the HvNAS1 gene and therefore tolerate iron deficiency.
