ABSTRACT:The energy balance for the production of sunflower oil and cake was carried out during the agricultural and industrial stage phase, where it was considered a cold extraction by hydraulic pressing, with the plant location in a rural area with a radius of 30km range. Data on productivity was used in two varieties of sunflower (Helio 358 and Aguará 04) grown in different seasons (2007/2008, 2008/2009), under different irrigation levels. Data showed that irrigation resulted in an increase in productivity of both varieties, and the best response was observed for Aguará 04 variety. Moreover, the increased intensity of irrigation negatively affected the energy balance, reducing the ratio between energy produced and energy used in the production chain. The most significant inputs in the energy intake were fertilizer followed by diesel oil, when irrigation was not used for. When the irrigation technique was used, the most significant inputs, in order of representativeness, were: energy, fertilizer and equipment.KEYWORKS: bioenergy, sunflower, irrigation, energy balance. IMPACTO DA IRRIGAÇÃO NA PRODUTIVIDADE E NO BALANÇO ENERGÉTICO DA PRODUÇÃO DE ÓLEO E TORTA DE DUAS VARIEDADES DE GIRASSOLRESUMO: Realizou-se o balanço energético para a produção de óleo e torta de girassol na fase agrícola e na fase de extração a frio por prensagem hidráulica, com a localização da usina em área rural, num raio de abrangência de 30km. Foram utilizados dados de produtividade de duas variedades de girassol (Helio 358 e Aguará 04) cultivadas em safras distintas (2007/2008, 2008/2009), submetidas a diferentes lâminas de irrigação. Os dados mostraram que a irrigação propiciou aumento de produtividade das duas variedades, sendo que a melhor resposta foi observada para a variedade Aguará 04. Por outro lado, o aumento da intensidade de irrigação afetou negativamente o balanço energético, reduzindo a relação entre energia extraída e energia utilizada na cadeia de produção. Os insumos mais representativos nas entradas de energia foram os fertilizantes, seguidos pelo óleo diesel, quando não se utilizou de irrigação. Quando utilizada a técnica de irrigação, os insumos mais significativos, em ordem de representatividade, foram: energia elétrica, fertilizantes e equipamentos.PALAVRAS CHAVE: bioenergia, girassol, irrigação, balanço de energia.

ÖzBu araştırma, Eskişehir koşullarında farklı giberellik asit (GA 3 ) dozları uygulanan ayçiçeğinde verim ve verim öğeleri ile tohuma uygulanan GA 3 dozlarının abiyotik stres koşullarında çimlenme üzerine etkilerini belirlemek amacıyla yürütülmüştür. Çalışmada materyal olarak Sanbro MR ayçiçeği çeşidi ile GA 3 kullanılmıştır. 2013 yılında yürütülen tarla denemelerinde kontrol (saf su), 50, 100, 200, 300 ve 400 ppm GA 3 dozları bitkiler 6-8 yapraklı (V 6 -V 8 ) olduğu dönemde uygulanarak verim ve verim öğeleri incelenmiştir. Çimlendirme denemelerinde, aynı dozlarda GA 3 ayçiçeği tohumlarına 8 ve 16 saat süreyle uygulanarak tuz ve kuraklık stresinde çimlenme performansları incelenmiştir. Araştırma sonuçlarına göre, artan GA 3 dozları çiçeklenme süresinin 2 gün kısalmasını sağlamıştır. Bitki boyu ve bin tane ağırlığı GA 3 dozları ile artmasına rağmen, çiçeklenme süresi, tabla çapı, bitkide tane verimi, yağ oranı, yağ verimi ve klorofil içeriği azalmıştır. Laboratuvar denemelerinde ise özellikle düşük dozlarda uygulanan GA 3 dozları tuz ve kuraklık stresinde etkili olmuştur. Tohuma 8 saat süreyle uygulanacak 50 ppm GA 3 dozunun tuz stresinin çimlenme üzerine etkisini azaltmak bakımından yararlı olabileceği sonucuna varılmıştır. AbstractThis study was carried out to determinate the effects of different gibberellic acid doses on sunflower yield, yield components in Eskişehir conditions and to detect the GA 3 doses on seed germination under abiotic stress conditions. Field and laboratory experiments were performed in 2013 using Sanbro MR and gibberellic acid as materials in this study. Yield and yield components of sunflower were investigated after gibberellic acid doses of control (distilled water), 50, 100, 200, 300, 400 ppm were pulverized to the plants with growing stage of 6-8 leaves (V 6 -V 8 ). Salinity and drought stresses were performed by using the same doses of GA 3 applied to the seeds both for 8 and 16 h. According to the research results, although plant height and one thousand seed weight enhanced by increasing GA 3 doses, blooming time, head diameter, seed yield per plant, oil content, oil yield, chlorophyll content decreased. Increasing GA 3 doses shortened two days of blooming time. In laboratory experiment, especially lower doses of GA 3 were effective for salt and drought stresses. It was concluded that seed treatment with 50 ppm dose of GA 3 for 8 h can be beneficial for decreasing the effect of abiotic stress conditions on germination.

“…Undoubtedly, supplemental irrigation is an effective way to maintain or increase sunflower yield (and oil concentration) in dry conditions (Rinaldi, 2001;Göksoy et al, 2004;Demir et al, 2006;Champolivier et al, 2011;Klocke et al, 2013) but future water resources could be limited because of competition among users especially in the Mediterranean area (Falloon and Betts, 2010). More water in winter could however be stored (dams, lakes, etc.)…”

-Climate change is characterized by higher temperatures, elevated atmospheric CO 2 concentrations, extreme climatic hazards, and less water available for agriculture. Sunflower, a springsown crop often cultivated in southern and eastern regions of Europe, could be more vulnerable to the direct effect of heat stress at anthesis and drought during its growing cycle, both factors resulting in severe yield loss, oil content decrease, and fatty acid alterations. Adaptations through breeding (earliness, stress tolerance), crop management (planting dates), and shifting of growing areas could be developed, assessed and combined to partly cope with these negative impacts. New cultivation opportunities could be expected in northern parts of Europe where sunflower is not grown presently and where it could usefully contribute to diversify cereal-based cropping systems. In addition, sunflower crop could participate to the mitigation solution as a low greenhouse gas emitter compared to cereals and oilseed rape. Sunflower crop models should be revised to account for these emerging environmental factors in order to reduce the uncertainties in yield and oil predictions. The future of sunflower in Europe is probably related to its potential adaptation to climate change but also to its competitiveness and attractiveness for food and energy.Keywords: CO 2 / temperature / crop model / biotic stress / water deficit Résumé -Culture du tournesol et changement climatique : vulnérabilité, adaptation et potentiel d'atténuation via des études de cas en Europe. Le changement climatique se caractérise par des températures élevées, de plus fortes concentrations atmosphériques en CO 2 , des risques climatiques extrêmes et moins d'eau disponible pour l'agriculture. Le tournesol, culture semée au printemps dans le sud et l'est de l'Europe, pourrait être plus exposé à l'avenir aux fortes températures et à un déficit hydrique marqué dès la floraison, avec pour conséquences des pertes de rendement, une diminution de la teneur en huile et une altération de la composition en acides gras. Des adaptations sont possibles à court et moyen terme par la sélection (précocité, tolérance aux stress), la conduite de culture (date de semis) et le déplacement des zones de production, permettant de faire face en partie aux impacts négatifs attendus. Ainsi le tournesol pourrait être cultivé plus au nord participant utilement à la nécessaire diversification des bassins céréaliers. En outre, la culture de tournesol étant faiblement émettrice de gaz à effet de serre par rapport aux céréales ou au colza pourrait contribuer davantage à la solution climatique apportée par l'agriculture. Les modèles de culture devraient être revus pour mieux tenir compte de ces facteurs environnementaux émergents si l'on veut réduire les incertitudes dans les prédictions de rendement et de teneur en huile. L'avenir du tournesol en Europe est probablement lié à son potentiel d'adaptation au changement climatique, mais dépendra aussi de sa compétitivité et de son attractivité en t...
