Abstract

The experiment was conducted in Alamria-Fallujah at Anbar proviance during spring season of 2010-2011 to study the effect of foliar application with humic acid and soil mulching and their interaction on some features of vegetative and rooting growth and yield of strawberry Rubygem &Fern variety. The foliar application of humic acid with 0, 1,2and4 ml/L where tow minds mulching with straw , black plastic in addition to control treatment without mulching were used. Factorial experiment with Randomized Complete Block Design RCBD in three replicates .The best result in total leaves area/plant, the percent of fruit set and total yield and root content of dry matter were obtained in Fern which get (1879.9cm2,, 62.83%, 166.08gm and 41.87gm)respectively. Mulching soil also had a significant effect on plant growth and yield and the treatment mulching straw the best result in mention characters which get (1592.3cm2, 40.92gm, 68.48%, 168.04gm) respectively. Foliar application with humic acid had a significant effect on average total leaves area/plant, root content of dry matter, the percent of fruit set and yield/plant which get (1968.2cm2, 44.42gm, 67.09%, 189.19gm) respectively. The interaction between mulching and foliar application had a significant effect in both varieties all mention of features.
