Effect of some growing media on growth and flowering of Gazania plant [electronic resource]

Includes references.

The present investigation was carried out at the Horticulture Research Institute, Agricultural Research Center, Ministry of Agriculture, Alexandria Egypt during the year of 2012 at two different locations Le. Maamoura and Montaza .. The aim of this study was to evaluate the effects of using 6 'different media which produced from adding different ratios (v/v) of compost or/ and sand to the calcareous soil on the vegetative growth, flowering characteristics and some chemical analysis of Gazania rlgens L grown in 25 cm diameter clay pots. Generally results of the two locations revealed that using calcareous soil alone gave the lowest values of most of the studied parameters of Gazanla plant, compared with other media. While adding compost at 25% or 50'Vo to the calcareous soil led to significant increases of almost all the measured parameters of Gazania plant, compared with using calcareous soil alone. Furthermore, adding sand at 25% or 50% to the calcareous soil or using an equal mixture of calcareous soil at 33.3%, compost at 33.3'Vo and sand at 33.3°/o did not gave any significant effect on most of the studied parameters of Gazanla plant, compared with using calcareous soil alone with exceptions of inflorescence diameter, pedicle length, inflorescence dry weight and leaf content ofN, P, K, Mn and Zn. It can be generally recommended to add compost at 25% to the calcareous soil to obtain a good growing medium for growing Gazania rlgens with high quality
