Abstract

An experiment was conducted during winter season of 2006 - 2007 in unheated plastic house at College of Agriculture – Basrah University . The objective of the experiment was to study the effect of stem numbers/plant(one and two.) and soil mulching (with or without black polyethylene). Randomized Complete Block Design was used with three replicates . Duncan's, Multiple Range Test was used at probability of 0.05 to compare mean variations . Results can be summarized as follows:- Plants growth with two stems gave significant increases in total leaf number/plant, fresh and dry weights of vegetative growth, flower number/inflorescence , flower number/plant and inflorescence number/plant ,early and total plant yields, production of plastic house and yield /donum, while plant grown with one stem gave significant increase in plant height.The soil mulching gave a significant increases in total leaf number/plant, fresh and dry weight of vegetative growth, flower number/inflorescence , flower number/plant , inflorescence number/plant and early plant yield. Whereas, soil mulching was not significantly influenced plant height, total yield /plant, total production of plastic house and donum production.Interaction between plant training and soil mulching gave a significant effects on all studied parameters.
