Effect of spraying with dry yeast (Saccharomyces cerevisiae) and boron on the growth and production of the strawberries plant cultivated under the conditions of protected agriculture

Abstract

This study was conducted in one of the greenhouses belonging to the nursery of the Horticulture and Forestry Division in the Department of Plant Production, Directorate of Agriculture, Najaf province for the season 2016-2017 to study the effect of spraying with dry yeast (Saccharomyces cerevisiae) and boron and their interaction on the growth and production of the strawberries plant. The study included 9 treatments: spraying the plants with two concentrations of dry yeast (1, 2 g.L-1) in addition to distilled water only with three concentrations of boron (0, 2, 4 g.L-1). The experiment was conducted as a factorial experiment according to the design of the Randomized Complete Block Design (RCBD), with three replicate. The results showed that spraying the plants with dry yeast led to a significant increase in the plant height and the number of leaves at the concentration of (1 g.L-1), while the spraying treatment with concentration (2 g.L-1) gave a significant increase in the dry weight of the total vegetative, the leaves content of chlorophyll and the fruits content of Total sugars, The average production of one plant and the average production of the greenhouse. The spraying with boron showed a significant increase in the traits of vegetative growth and the of the yield traits at a concentration of (2 g.L-1). Interactions of the study factors had a significant effect on all studied traits.
