Abstract

In 1997 and 1998, the effect of different fertilizer systems on energy flow and efficiency traits of 4 SUNFLOWER cultivars were evaluated in Miandoab Agricultural Research Station, Iran. In both years, a split plot design in randomized complete block arrangement was used. The main plot was composed a various levels of chemical fertilizers N (40, 80, 120, 160 and 200 kg/ha) different levels of manure (6, 12, 18, 24 and 30 ton/ha) and a mixture of different rates of chemical fertilizers and manure N=40kg+ 24 ton/ha, N=80kg+18ton/ha,N=120+12ton/ha and N= 160kg + 6ton /ha) and control (no fertilizer) treatment. The four cultivars, Hysun-33 and As-508 hybrids, and Armaverski and Record O.P.S., was made up of sub plot and randomized in fertilizer treatments. Grain and oil energy output and efficiency were determined. The results obtained from the first and second years of the experiments showed that the different fertilizer treatments had significant effects on grain, and oil energy and efficiency increase of application of N fertilizer and manure grain and oil energy output and efficiency recorded also increased, and highest grain and oil energy was obtained in both years of experiments in chemical fertilizer systems, with N =200 kg/ha treatment and with ORGANIC fertilizer of 30ton/ha. Integrated fertilizer systems, had produced high oil and grain energy and efficiency of energy. The results showed that mixture of chemical fertilizer and manure improved efficiency use of chemical fertilizer and could decrease the use of chemical fertilizer in the cultivated land. The hybrid cultivars produced significantly high seed and oil ENERGY EFFICIENCY than the other cultivars and suitable for culture in the Mindoab plain.
