| Abstract | ||
| This investigation was carried out at Demo location EI - Fayoum. Egypt during two successive seasons (1999 - 2000) and (2000 - 2001 ). The design of the experiment was split-split plot, the main plot was planting dates (t" November, 15th, November and 1st, December), sub - plot was plant spacing ( 20 and 40 cm. between plants ) and sub - sub plots was micronutrient treatments (CUS04 .5H20 , Mn - EDTA, and Fe - EDTA ) as a foliar spray applied twice, for each season. . The main results are summarized as follows: Statistical analysis of the results indicated that fresh weight of yield and oil yield I fed dan were significantly affected by sowing dates and spacings among plants in the two seasons. The highest fresh weight I feddan was recorded for plants planted on Nov. 15th, and spaced at 20 cm. among plants, followed by early November in the two seasons. Fresh weight of yield was decreased by delaying planting date at first December. Data also indicated that the highest value ( ton I feddan ) and oil yield I fed were obtained when plants were grown at the 'narrow distance ( 20 cm.) among plants. The average fresh weight of yield was significantly increased by foliar applications with all micronutrients. The order of increases was Fe > Mn > Cu > untreated. • Fe, Mn and Cu - concentration in leaves was increased on 15 - November sampling date in the two seasons. 5. All micronutrient treatments increased Fe, Mn and Cu - concentration in leaves compared to the untreated plants. | ||
