    Effect of row space and irrigation on seed composition of Turkish sesame (Sesamum indicum L.)
    (Wiley, 2001) Alpaslan, M; Boydak, E; Hayta, M; Gerçek, S; Simsek, M
    The effect of row space (RS) and irrigation (IR) on total protein, total oil, and fatty acid composition of Harran-grown sesame seed was studied. Total oil content of sesame varied from 46.4 to 51.5%. The oil and protein contents were significantly different among treatments (P < 0.01) in 1998 and 1999. IR affected oil content significantly (P < 0.01) in both years, and RS had no significant effect. The protein content was significantly influenced by RS and IR at P < 0.05 and P < 0.01, respectively. RS 70 cm had the highest protein content followed by RS 60, 50, and 40 cm, respectively. IR every 24th day resulted in the highest level of protein, followed by 18th-, 12th-, and 6th-day irrigation, respectively. Correlation coefficients between protein and oil content were -0.34 in 1998 and -0.59 in 1999. RS (P < 0.05) and IR (P < 0.01) influenced oleic and linoleic acid contents significantly. Interactions of RS and IR were also found to be significant (P < 0.05) over the oleic and linoleic acid levels.

    Seed composition of Soybeans grown in the Harran region of Turkey as affected by row spacing and irrigation
    (Amer Chemical Soc, 2002) Boydak, E; Alpaslan, M; Hayta, M; Gerçek, S; Simsek, M
    This study was conducted to determine the effects of row spacing (RS) and irrigation (IR) on protein content, oil content, and fatty acid composition of soybeans grown in the Harran region of Turkey. Oil content of the seed varied from 20.9 to 22.3%. Oil and protein contents were both affected by year. RS and IR affected protein and oil contents significantly (P < 0.01) in both years. RS of 70 cm had the highest protein content, followed by RS of 60, 40, and 50 cm, respectively. IR every 3rd day resulted in the highest level of protein, followed by 6th, 9th, and 12th day irrigation, respectively. The correlation coefficient (r) between protein and oil content was -0.791 in 1998 and -0.721 in 1999. RS (P < 0.01) and IR (P < 0.01) influenced oleic and linoleic acid contents significantly. Interactions of RS and IR were also found to be significant (P < 0.05) for the oleic and linoleic acid contents of soybeans.
