الملخص EN

This research was conducted during the winter season of 2014/2015 inside unheated green house in Technical Institute Musayab, to investigate the effect of sprays numbers and different concentrations of nutrient foliar AL- Nebras ( 0.0, 1.0, 1.5, 2.0 and 2.5 cm3 .l-1) and their interaction on growth and yield of Eggplant var.

Barshelona using (RCBD) with three replicates.

Results showed that the sprays number and the concentrations of AL- Nebras and their interaction had a significant effect on vegetative growth characteristics and yield.

The interaction of three sprays with 2.5 cm3 .l-1 of ALNebras gave the highest average of plant height (103.34cm), branches number.plant-1 (11.98) , leaves number.plant-1 (116.87) leaf area.plant-1, ( 198.99 dc2) flowers number (72.86) and set of flowers percentage (91.12).

Results also gave the highest average of fruits number.plant-1, fruit long, fruit weight, yield.

Plant-1, early yield, and total yield /greenhouse amounted to( 38.67, 21.67cm, 121.88gm, 4.713kg, 0.788ton, 9.049ton) respectively.

While the average was 10.54 fruits number.plant-1, 11.22 cm fruit long, 80.55g.

fruit weight, 0.848 kg.

total yield.

Plant-1, 0.143 ton early total yield and 1.631ton yield/greenhouse respectively for control treatment.
