Abstract

An experiment was conducted during the winter seasons of 2015- 2016 in unheated plastic houses , Department of Horticulture, College of Agriculture, Al-Qasim Green University, to study the effect of Biofertilizer (Bacteria mix) and Nutrient Solution (Primo) on growth and yield of eggplant. This experiment was designed according to (R.C.B.D) with three replicates and two factors. The first factor included two levels of Biofertilizer (0 and 20 g.L-1) and the second factor was three levels of nutrient solution ( 0 , 2.5 ml.L-1 foliar application and 5 ml.L-1 ) applied to the soil. Using Biofertilizer with nutrient solution showed a significant effect in growth and yield characteristics of eggplant. The treatment 20 g.L-1 biofertilizerwith 5 m.L-1 nutrient solution applied to the soil gave the highest average in plant height , number of branches , number of leaves , chlorophyll content , leaf area, percentage of dry weight of leaves , length of fruit ,early yield per plant, early total yield and percentage of N,P,K in leaves ( 80.33 cm ,11.00 branch.plant-1, 88.00 leaf.plant-1, 58.6 %, 2288 cm2, 12.957%, 15.20cm,1.057 kg.plant-1, 0.887ton.plastic houses , 2.287%, 0.432%, 2.680% ) respectively as compared to control treatment which gave lowest average ( 55.00 cm , 5.67 branch.plant-1, 57.00 leaf.plant-1, 39.5 %, 1211cm2, 10.447 %, 10.737 cm , 0.450 kg.plant-1, 0.378 ton.plastic houses, 1.093 %, 0.292 % , 1.313% ) respectively.
