Influence of Using Water Hyacinth Bio-Fertilizer and Micro-Organisms (EM) on Eggplant

摘要

Tow field experiment were conducted during the two successive summer seasons of 2017- 2018 on eggplant (Solanum melongena L). cv. Laala-2 as two experiments one on the nursery (to investigate the effect of seed soaking at six hours in EM (Effective micro-organisms) and water hyacinth bio-fertilizer (WHB) using three concentrations from 30, 60, 90% from both compounds), while the second as field experiment. The two experiments were conducted at the Experimental Farm of Kaha Station, Qalubia Governorate, Egypt in clay soil. The aim of the current experiment was to examine the effect of two rates from the recommended mineral NPK of eggplant i.e.100% (as control) and 50%, as treatments whereas distribution in the main plots and four safety materials, i.e. water (as control), EM (Effective micro-organisms) at 3ml/l and water hyacinth bio-fertilizer (WHB) at1.5ml/L as foliar spray and their interactions which were arranged in the subplots and the influence of that on the vegetative growth, yield and its components of eggplant. The results indicated that, all different seed soaking treatments had highest values of all vegetative growth parameters, leaf chlorophyll concentration and germination parameters of the seedling at the nursery compared with seedling produced without soaking (control) or seeds soaked in water, it is notice that the using seed soaking in WHB 60% gave favorable significant values on seedling growth and germination parameters compared with the other treatments. Moreover, it noticed that in the field experiment the all treatments used, i.e. foliar spray by EM and WHB led to increment in the vegetative growth parameters, total yield and its components in the two seasons compared with the control, in addition the highest fruit yield (33.29 and35.51 ton/fed at the two successive seasons was obtained from the treatment of No9 (soaking eggplant seed in WHB 60% spraying plants by WHB at 1.5 ml/L) comparing with the control which produced 27.08 and 27.38 ton/fed in the two seasons . The same treatment produced the pest fruit quality and the concentration of K% and total phenols in the fruits.
