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.
