Drinking water is the most indispensable substance for humans. Bottled drinking waters are preferred over tap water with the belief that they are more nutritious, better quality, more delicious and safe in terms of health. Therefore, the Turkish bottled (spring and mineral) water market has experienced a continuous growth since 2003, as in the whole world. This study focuses on comparing the common mineral cation calcium (Ca2+), magnesium (Mg2+) and sodium (Na+) content of twenty one popular bottled spring and mineral water brands marketed in Turkey by using an inductively coupled plasma optical emission spectrometry (ICP-OES). The average concentrations of Ca, Mg and Na analyzed in bottled spring and mineral water samples were found as 14.9, 24.1 and 8.2 mg/L and 147.9, 44.3 and 117.3 mg/L, respectively. This comparison confirms that bottled natural mineral water has better quality in terms of major nutrient minerals than bottled natural spring waters.

Rabia Göçmen | Gülşah Kanbur
This study was conducted to investigate the effects of hemp seed oil replaced soybean oil as an energy supply on growth performance parameters, carcass yield, liver weight, breast meat pH, and meat color values in quails. A total of 100 one-day old quail chicks were reared in two treatment groups for 5 weeks. The experimental diets were formulated as to contain 4.4% crude soybean(control) and hemp seed oils. According to the results of the present study, crude hemp seed oil replaced soybean oil in the diet was effective on finishing body weight, feed intake, feed conversion ratio, weight gain and carcass yield. All of these parameters were lower than the soybean oil (control) group. Liver weight, and breast meat color values (L*, a*, and b*) have shown similarities between experimental groups. The breast meat pH value decreased significantly in the hemp seed oil treatment group compared to soybean oil group. Using hemp seed oil instead of soybean oil used in quail diets negatively affects performance parameters (except for feed conversion ratio).

The level of yield among sweet potato farmers is on a decline; low output and yield differences was observed, indicating the existence of inefficiency in production systems and variations in input utilization. Efficiency in resource use must be sustained in order to improve productivity and maximize farm output. This study therefore analyzed the technical efficiency of sweet potato production. Multi-stage sampling techniques were adopted in selecting 94 respondents for this study. Data collected was analyzed using descriptive statistics and stochastic frontier production function. The socioeconomic variables of the respondents affected their farm efficiency and level of farm output. The estimated ratio of the L/R test was 0.579; indicating a goodness of fit of the frontier model and thus a rejection of the null hypothesis. The coefficients of sweet potato seeds (vines) (0.362) and labour (0.439) were positive and statistically significant at 5% level of probability, while the coefficients of farm size (-1.333), fertilizer (-0.452) and herbicides (-0.766) were negative but statistically significant at 5% level of probability. The inefficiency model revealed that the coefficient of farm capital (-0.172), education (-2.281), access to credit (-0.472), farming experience (-0.639), extension contact (-0.733) and membership of cooperatives (-0.396) were negative and statistically significant at 5% level of probability. The mean technical efficiency was 0.62 (62%) implying that the sweet potato farmers in the study area were not producing at optimal capacity. The constraints identified significantly affected sweet potato production in the study area. Subsidizing input costs; sensitizing farmers on appropriate farming practices, cooperative formation and efficiency in resource utilization; improving access to agricultural inputs, technology, farm capital, credit and extension services, market linkages, farm labour supply and the development of indigenous technologies in sweet potato production are strongly recommended.

Compared to industrial wastes, the recycling of agricultural wastes is more efficient because they are organic. The low organic matter content of Anatolian agricultural lands makes the recycling of agricultural wastes even more important. In the Samsun region, compost centres are recommended in order to help increase productivity in agricultural production, develop agricultural activities and ensure rural development. It is very important to use natural fertilizers because it is to protect and improve the organic structure of the soil. The low production costs of organic fertilizers compared to chemical fertilizers provide an advantage to farmers and prevent foreign exchange loss. In this study, it is aimed to determine the animal existence and optimum facility locations for evaluation of animal wastes as compost in Samsun. For this purpose, the number of animals of the enterprises in the region was determined by using the data obtained from Samsun Provincial Directorate of Agriculture and Forestry. The coordinates of the settlements of 1,284 enterprises with bovine capacity of 40 or more in Samsun were determined according to the rectangular coordinate system. In terms of animal distribution in Samsun province, 27 cluster numbers were preferred through Elbow method and f(K) Function method. The location of most suitable compost production centres according to the distance and the total number of animals was determined by the K-Means clustering analysis method using geographical coordinates. For Samsun, the group size was taken as 2,000-10,000 cattle and the enterprises with a focal length less than 15 km were included in the compost production clusters. In line with these criteria, 10 compost production clusters for compost production have been determined in Samsun and the locations of these cluster centres are shown on the map in a way that will provide the most efficient information to investors and relevant institutions.

The aim of present study was to determine the effects of different ethephon doses on grain yield and yield components of two faba bean cultivars. The experiment was established in 2019/2020 and 2020/2021 cropping season at Research Area of Field Crops Department, Agriculture of Faculty, Cukurova University Adana, Turkey. The field experiment was laid out in randomized complete blocks design (RCBD) with three replications on the basis split plot design with cultivars (Luz de Otono and Histal) in main plots and ethephon doses (0, 500, 1000, 1500 g ha-1) in sub plots. Plant height (cm), branches per plant, pods per plant, seeds per plant, seed yield per plant (g), 100 grain weight (g), seed yield (kg ha-1) were investigated. Differences among the cultivars and ethephon applications were significant for seed yield and it varied from 1782 to 3388 kg ha-1 in the mean of the years. Seed yield also decreased with increasing ethephon doses. Seed yield was higher in 2019/2020 (3355 kg ha) than 2020/2021 (1841 kg ha-1) where low rainfed and high temperature. The present results suggested that ethephon applications at inititation of flowering were not useful for seed production of faba bean.

Mehmet Veysi Çetiz | Abdulrezzak Memon
Bitkilerde ve üzerinde yaşayan mikroplar (bitki mikrobiyomu) bitki sağlığı için kritik öneme sahiptir ve besin alımını kolaylaştırarak, bitki hormon seviyelerini düzenleyerek ve patojen saldırısına karşı koymaya yardımcı olarak etkilerini gösterirler. Bitkiler karmaşık mikrobiyomlarla ilişkili meta organizmalardır. Bitki yüzeylerinde (epifitler) veya bitki dokuları (endofitler) içinde bulunan mikroorganizmaların çoğu, herhangi bir bitki hastalığına neden olmaz, ancak genellikle konakçı bitkilerinin besin tedarikine önemli ölçüde katkıda bulunur. Ayrıca bitki mikrop etkileşimi sekonder metabolit miktarında değişimlere neden olur. Bu derlemede, bitki sekonder metabolit miktarını artıran bitki ve kökle ilişkili mikrop (Rizosfer) arasındaki etkileşimine odaklanarak bu fenomeni destekleyen mekanizmalar hakkında anlayışımızı geliştirecek detaylı bilgiler verilmektedir.
