Genetic Variability for Seed Yield, Oil Content and Fatty Acid Composition in Germplasm Accessions of Sunflower (Helianthus annuus L.) and Their Response to Different Seasons

This study was carried out to determine the efficiency of nitrogen (N) doses (0, 30, 60, and 90 kg N ha−1) under supplemental potassium (K) application (50 kg K2O ha−1) on black cumin in 2011 and 2012. The results showed that increased N levels resulted in increasing seed yield and N and K contents in seed, while oil content decreased. The seed yield and oil yield were peaked at the doses of 60 kg N ha−1and 50 kg K ha−1. An increase in N doses caused a reduction in oil content regardless of K supply. Saturated fatty acids and oleic acid were slightly increased by K application, while minor changes in linoleic acid were detected. It was concluded that 60 kg N ha−1with supplemental K application should be advised for enhancement in seed yield, oil yield, and N and K contents in seeds of black cumin without significant changes in fatty acid composition.

Ridomil MZ alone or Ridomil MZ followed by protectant fungicides was tested to manage white rust (Albugo candida) (Pers. ex Lev.) Kuntze on Brassica juncea L. var. RL-1359, sown at the normal time in 1989–90 and 1990–91 and under delayed sown conditions in 1990–91 at 2 different geographical locations of the Punjab state. Two spray applications of aqueous suspension of Ridomil MZ at 450 g a.i./ha or 1 foliar application of Ridomil MZ at 450 g a.i./ha, followed by another spray of Dithane M-45 at 600 g a.i./ha or Blitox-50 at 375 g a.i./ha at 15- or 20-day interval to a 70-day-old crop significantly reduced both foliage and floral infections. These treatments significantly increased the seed yield over control and other treatment combinations, without having an adverse affect on the oil content and fatty acid composition of the oil. The same fungicide regime was effective to control white rust when applied to a 50- or 60-day-old crop under delayed sown conditions. The seeds harvested from the plots treated twice with Ridomil MZ exhibited no detectable residue of metalaxyl and mancozeb. The timing of application of these fungicides may be critical in the control of white rust, particularly in the late sown crop.
