SUMMARYA field study was conducted on four desiccants; Dimethipine, Metoxuron (Dosanex), Drop-leaf and Diaquat, during 1990 and 1991. Two rates of each desiccant were sprayed on sunflower (Helianthus annuus L.) hybrid NK-212 15 days after flower completion. Two harvesting dates (10 and 20 days) after desiccant application were superimposed on each desiccant treatment. The objective of this specific study was to determine the relative efficacy of different desiccants at two different rates, harvested on two different dates after application and their consequent effect on seed yield, oil quality and other agronomic characters of sunflower. As an average of the two years, desiccant treatment means were significantly different for all the traits studied. The lowest seed yields (1667 and 1674 kg/ha) were obtained from lower and higher doses of Diaquat, respectively. Conversely, higher yields were obtained by both rates of either Drop-leaf (2222 and 2342 kg/ha) or Metoxuron (2121 and 2168 kg/ha) as compared with the other treatments. Application of Diaquat and Dimethipine reduced the yield significantly as compared with the control, Drop-leaf and Metoxuron (Dosanex). Similarly, low and high oil contents were attributed to Diaquat and Drop treatments, respectively. This study concluded that Dropleaf and Metoxuron (Dosanex) can be safely used as desiccants on sunflower at the rates of 0.225 and 0.750 kg ai/ha, respectively. The sunflower crop should be harvested 35 days after flower initiation or 25 days after flower completion to get higher seed yield, oil content and low seed moisture contents to minimize the post harvest losses and simultaneously vacate the field 5 to 10 days earlier for the subsequent crop.

KUALITAS MINYAK BUNGA MATAHARI KOMERSIAL DAN MINYAK HASIL EKSTRAKSI BIJI BUNGA MATAHARI (Helianthus annuus L.) 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. Kata kunci: Asam lemak bebas, bilangan proksida, minyak biji bunga matahari  QUALITY OF COMMERCIAL SUNFLOWER OIL AND OIL EXTRACTION SEEDS SUNFLOWER (Helianthus annuus L.) 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
