Four oilseed sunflower (Helianthus annuus L.) hybrids, varying widely in growth habit, were grown with rows uniformly spaced at 45 cm and in a paired-row arrangement, alternating 30 cm with 60 cm, in 1986 and 1987 at Morden, Manitoba. Soil moisture conditions were adequate in both seasons. There were no significant differences in achene yield between the row spacing treatments.Key words: Sunflower, Helianthus annuus L., row spacing, paired rows

Growth compensation of dwarf sunflower (Helianthus annuus L.) hybrids to low initial stands, later stand losses, or plant defoliation has not been reported regarding replanting decisions and crop insurance yield loss assessment. Three experiments were conducted to study the affect of stand reduction, defoliation, and row spacing on dwarf sunflower yield and quality when grown in eastern North Dakota. Experiment 1 evaluated stand reduction (0, 25, 50 and 75%) applied at growth stages (V4, R1 and R6) in 15, 45 and 76 cm spaced rows. Row spacing interactions with stand reduction and growth stage were not significant for yield indicating growth stage and stand reduction effects on yield response were independent of row spacing. In exp. 2, significant growth stage (V4, V8, R1, R2, R3, R5 and R6) by stand reduction (0, 12, 25, 37, 50, 62 and 75%) interaction showed stand reduction at vegetative growth stages not influencing yield, but as maturity progressed yield reductions became greater with increased stand reduction. Achene weight increased with increasing stand reduction at vegetative and early reproductive stages. A reciprocal relationship was noted between achene weight and achene oil content where oil content decreased as achene weight increased. Interaction of growth stage (R1 and R6) and defoliation (0, 25, 50, 75 and 100%) in exp. 3 indicated greater reduction in yield, test weight, 1000-achene weight, and achene oil conte nt as defoliatin increased at growth stage R6. Yield compensating ability of dwarf sunflower is dependent on type and level of damage and growth stage of occurrence, with total yield reduction considering all effects.

ABSTRAK Minyak komersial dan minyak hasil ekstrasi dari biji bunga matahari melalui uji kadar air, kadar asam lemak bebas, bilangan peroksida. Analisis hasil ekstrak biji bunga matahari diperoleh kadar air 0,43%, kadar asam lemak bebas 0,47% dan bilangan persoksida 5,22 mek/kg. analisis minyak komersial diperoleh kadar air 0,21%, kadar asam lemak bebas 0,28% dan bilangan peroksida 4,18 mek/kg. Hasil analisis dengan kromatografi gas kedua sampel menunjukkan kadar asam lemak bebas berbeda.       Berdasarkan uji kualitas yang dilakukan terhadap kedua sampel yang dianalisis terdapat hasil yang diperoleh tidak memenuhi syarat yang ditentukan yakni kadar asam lemak bebas 0,08% dan bilangan peroksida 2 mek/kg.

ABSTRACT Experimental study of analyzing the extract oil from sunflower seed compare with the commercial sunflower seed oil according to the company standard which includes determining of moisture content, free fatty acid content, peroxide value and the fatty acids compositions is reported in this paper. The result show that the moisture content of the extract oil is 0,43%, free fatly acid content is 0,47%, and the peroxide value is 5,22% mek/Kg. For the commercial sunflower seed oil company product that is 0,21% for the moisture, free fatty acid is 0,28% and the peroxide value is 4,89 mek/Kg. The gas chromatography analysis indicated that the most fatty acid from both samples is linoleic acid. The quality of the extract sunflower seed oil has not been improved to conform with the commercial quality according to the company standard, that is 0,08% for the free fatty acid and 2 mek/Kg for the peroxide value. Keywords: Free fatty acid, peroxide value, sunflower seeds oil
