In agricultural production, one of the limiting factors on plant growth and yield is soil salinity. The plant growth regulators are of considerable importance in alleviating the negative effect of salt stress. The study was carried out to determine the effects of salicylic (SA) and gibberellic acid (GA3) on the growth and some physiological characters in canola (Brassica napus L.) under salinity conditions in greenhouse. For this purpose, a factorial experiment set up as completely randomized design was conducted with three levels of SA (0, 0.5 and 1 mM) and GA3 (0, 50 and 100 mg l-1) and four levels of NaCl (0, 50, 100 and 150 mM) with three replications. In the study, leaf area, plant height, electrolyte leakage, chlorophyll content and the loss of leaf turgor were investigated. Salt treatments reduced significantly all of the considered parameters, compared with the control. Salinity caused a significant reduction of 63 and 67%in plant height and leaf area, respectively, as compared to the control plants. On the contrary, electrolyte leakage was markedly increased (six-fold) with increasing NaCl levels. Gibberellic acid increased significantly plant height and reduced the loss of leaf turgor, without a significant improve in other parameters. The results indicated that application of SA and GA3 to salinity stressed plants did not significantly affect canola vegetative growth. However, GA3 caused a partial decrease in the adverse effect of salinity.

Ünal Şirin | Sedat Karaman | Fatih Mehmet Kızıloğlu
Milking parlours are concrete constructions where milk is milked from cows, stored and transferred. These create the last stage of the work flow chart in dairy cattle farms. Quality of milk is important in the production of milk and dairy products owing to the fact that milk is one of the basic food requirements of people. The quality of milk depends on the genetic conditions of the cows as well as their well-being, the appropriate level of care and environmental conditions and milk being obtained in a clean environment which isolated from negative external factors. Milking parlours should be planned under a separate roof from the dairy cattle barns in order to ensure hygiene conditions, facilitate the work flow and reduce the negative effects on the health of cows and people. However, not including very large enterprises, it is planned as an add-on to other items under the same roof with the dairy cattle barn due to reasons such as decreasing the cost in the small, medium and majority of large-scale enterprises and the society does not care about hygiene conditions. Production in this wise is not appropriate to ensure the requirements about hygiene conditions in the production of milk and dairy products, since the milking parlours are directly under the environmental conditions of the barn. In this paper, it is explained the criteria to be considered in the process to plan and design milking parlour and it is aimed the generalization of milking parlour be built as a construction separate from the dairy barn, with an exemplary milking parlour project with 2×12 fishbone milking system.

Known as the world’s most healthy and natural source of vegetable oil, the history of olives dates back to 10,000 years ago. The homeland of olives, a member of the Oleacea family, is Upper Mesopotamia and Southern Asia, including Southeastern Anatolia and Syria. Olives, BC It started to be cultivated on the eastern shores of the Mediterranean in the year 3000 and is one of the first fruit species cultivated in the Mediterranean region. In this respect, olive has an important place in the economy, nutrition and culture of Mediterranean countries. Currently, in most olive growing countries, olive, leafy stem or cuttings are rooted or by propagating stem shoots from seed or clonal stem. However, the so-called table olives are very difficult or completely impossible to root. The olives, which are very difficult to root, should be supported with biotechnological approaches such as micropropagation method in order to increase the product productivity. So far, many fruit species have been propagated in vitro using tissue culture methods and at the same time, some olive varieties have been successfully propagated by micro-propagation method. It made in tissue culture in the world and Turkey Olives have been compiled resources to work for the researchers in this study.

In wheat cultivation, sowing frequency is one of the crucial agronomic applications affecting grain yield. The aim of the research was to determine the effects of application of different sowing frequency (350, 500, 650 and 800 seeds m-2) for bread wheat cultivars (Alpu 01, Atay 85, Bezostaja 1, Harmankaya 99, Sönmez 01 and Sultan 95) on yield and yield components. Trials was carried out in Transitional Zone Agricultural Research Institute Eskişehir central campus fields during at 2012-13 and 2013-14 crop seasons in irrigated and rain fed conditions with 3 replications in randomized complete blocks design. In this study, the factors such as grain yield, number of spike per square meter, spike length, number of grain per spike, weight of grain per spike and harvest index were examined in terms of sowing frequency applications and cultivars in both conditions. As a result, the maximum grain yield was obtained from 650 seeds m-2 in rainfed conditions and this value was obtained from the application 500 seeds m-2 in irrigated conditions. Harmankaya_99 variety reached the highest values in terms of grain yield in both conditions and followed this by Alpu01 variety. In both conditions spike length, number of grain per spike, weight of grain per spike and harvest index parameters decreased inversely with increasing sowing frequency, while the number of spike number per square meter increased in direct proportion to increased sowing frequency. In rainfed conditions while there was a positive correlation between the grain yield with number of spike per square meter and harvest index, there was negative correlation among grain yield with spike length, number of grain per spike and weight of grain per spike. There was found significant positive correlation between grain yield with spike length and harvest index in irrigated conditions.
