Two field experiments were carried out at the experimental farm of the
Faculty of Agriculture, Fayoum University, Egypt during 2013 and 2014
summer seasons to study the effect of microelements foliar application and
nitrogen fertilization levels on growth, yield and yield components of two
sesame (Sesamum indicum L.) verities, i.e., V1: Shandaweel 3 and V2: Sohag 1.
A split split-plot arrangement in randomize complete block design with four
replications was used in both seasons. Two nitrogen fertilization levels, i.e., N1:
40 and N2: 60 kg N fed-1 allocated in the sub-plots and with three microelement
rates, i.e., M1: 200, M2: 300 and M3: 400 g fed-1 (were dissolved in 200L water
fed-1) distributed in the sub sub-plot, while varieties occupied the main plots.
The microelement were added in form of EDTA (Fe 7.5%, Mn 3.5%, Zn
0.70%, Cu 0.28%, B 0.65% and Mo 0.30% w/w). The obtained results showed
that Sohag 1 significantly surpassed Shandaweel 3 in growth parameters (i.e.,
plant height, stem diameter and number of capsules plant-1) as well as yield and
yield components (i.e., capsules weight plant-1, seed yield plant-1, seed, oil and
biological yields fed-1, harvest index and oil %. The N rate of 60 kg fed-1
significantly exceed the rate of 40 kg fed-1 over the two seasons. Microelement
foliar application at 400 g fed-1 gave significantly the highest values for all
traits over the two seasons as compared to 200 and 300 g fed-1.
