    Effect of Bacillus subtilis Ch-13, nitrogen and phosphorus on yield, protein and gluten content of wheat (Triticum aestivum L.)
    (Uludağ Üniversitesi, 2015-03-06) Kayın, Günsu Barışık; Öztüfekçi, Sencer; Akın, Hasan Fatih; Karaata, Ekin Ulaş; Katkat, A. Vahap; Turan, Murat Ali; Uludağ Üniversitesi/Ziraat Fakültesi/Toprak Bilimi ve Bitki Besleme Bölümü.
    The effects of Bacillus subtilis Ch-13 (BS0 Bacillus subtilis Ch-13 not applied and BS1 Bacillus subtilis Ch-13 applied) and chemical fertilizer CF0 (0 kg N da-1 , 0 kg P da-1 ), CF25 (5 kg N da-1 , 0.7 kg P da-1 ), CF50 (10 kg N da-1 , 1.4 kg P da-1 ), CF75 (15 kg N da-1 , 2.1 kg P da-1 ), CF100 (20 kg N da-1 , 2.8 kg P da-1 ) on yield, protein and gluten content of wheat (Triticum aestivum L. cv. Pehlivan), grown under natural climatic conditions were investigated. It is determined that yield, wet gluten and protein content of seed were increased by Bacillus subtilis Ch-13 application with increasing chemical fertilizer applications. Those effects of Bacillus subtilis Ch-13, nitrogen and phosphorus were found significantly important (P<0.01). However, the positive effect of Bacillus subtilis Ch-13 on yield decreased with increasing doses of chemical fertilizer. The highest yield (466.2 kg da-1 ) was obtained from CF100BS1 application. The maximum gluten and protein content have been determined in CF100BS0 (33.5 %) and CF100BS0 (10.6 %) applications respectively.

    The effects of feeding frequency on growth performance and proximate composition of young Nile tilapia (Oreochromis niloticus L.)
    (Uludağ Üniversitesi, 2015-03-16) Kaya, Gülderen Kurt; Bilgüven, Murat
    In this study, the effects of four different feeding frequency (once (I), twice (II), three (III), or six (VI) meals a day) on the growth performance, feed consumption, feed conversion ratio and proximate composition of Nile Tilapia (Oreochromis niloticus) were investigated. The average live weight of 420 Nile tilapia used in this experiment were 9.39 ± 0.19 g. Four trial groups were tested in triplicate for 10 weeks and 35 fish were stocked in each tank. The fish were fed with the feed (35% CP; 11.7 MJ DE/kg) taken from a commercial feed company. At the end of the study, it was observed that there were important differences among the groups in terms of average live weight, live weight gain, feed consumption, feed conversion ratio (FCR), protein efficiency ratio (PER) and specific growth ratio (SGR) were found statistically significant (P<0.05). Moreover, the difference in the composition of carcass among the groups is found statistically significant (P< 0.05).Consequently, it is understood that feeding frequency has an important effect on growth rate: there is a linear correlation in young fish, and there is a non- linear correlation in adult fish.

    One of the most socio-economically important sectors in Turkey is Food sector and it has grown rapidly in recent years. Bursa has become a brand city in Turkey, particularly in terms of fruit, vegetables and processed products industry, dairy industry, and beverages sector. When the export figures are analyzed, the food industry of Bursa has a significant proportion of the Turkey’s export figures. The purpose of this study was to conduct a sectorial analysis of food companies operating in Bursa and to determine their Research and Development (R&D) and test-analysis needs. In addition, this study aimed to find the problems experienced in this sector and to propose possible solutions to these problems. Based on the analysis, we found out that businesses operating in food industry in Bursa are in need of laboratory tests and analysis and have a lack of qualified employees for their R&D departments. We argue that universities can have an important role in solving these problems and that the collaboration between universities and industry can be enhanced by introducing some additional regulations to the universities’ policies.

    Yield, essential nutrients and essential oils of peppermint (Mentha x piperita L.) grown under organic farming conditions
    (Uludağ Üniversitesi, 2015-02-16) Esetlili, Bihter Çolak; Çobanoğlu, Özgür; Tepecik, Mahmut; Öztürk, Bintuğ; Anaç, Dilek
    The aim of this study was to examine the yield, essential plant nutrients (N, P, K, Ca, Na, Fe, Zn, Mn, Cu and B), essential oil and oil components of peppermint (Mentha x piperita L.) which was grown under organic farming conditions. Different certified organic fertilizers or natural inputs were the treatments of the study and tested in the nutrition of peppermint. Their effects on different parameters were examined. Results showed that fresh and dry herb yields differ according to the treatments and were found higher in the parcels where bone meal and potassium feldspate were given. Impact of different inputs/fertilizers on the secondary plant nutrients indicated that the pepermints of the parcels that received bone meal and potassium feldspate or rockphosphate and zeolite were richer in this regard. The essential oil yield (%) and compositions of essential oils of peppermint were highly affected by the bone meal applications.
