Effect of Zeolite and Mineral Fertilizers on Some Soil Properties and Growth of Jew's Mallow in Clayey and Sandy Soils

Aims: To evaluate the effect of zeolite and mineral fertilizers on some soil properties, availability of soil nutrients and yield of Jew’s mallow (Corchorus olitorius) in clayey and sandy soils.

Study Design: The experimental designed as split plot design with three replicates, the main plots were devoted to zeolite at the rates of 0, 4.76 and 9.52 Mg ha-1 and the sub plots were occupied by mineral fertilizers at the rates of 50% and 100% from the recommended NPK doses.

Place and Duration of Study: During spring and summer seasons of 2018, the field experiments were conducted in Sakha Agricultural Research Station Farm (clayey soil) and private farm at Baltium district (sandy soil).

Methodology: Jew’s mallow grains (Alexandria variety). Soil samples were collected at (0-30 cm depth) in the initial of experiment and after harvesting with the aid of soil auger at random from different parts of the experimental sites to determine the physicochemical and soil moisture characteristics of the soil. Growth characteristics (plant height and fresh mass weight) were studied.

Results: The results showed that ECe, SAR and bulk density values were decreased, while CEC, total porosity, field capacity, permanent wilting point and available water values increased due to application of 9.52 Mg zeolites ha-1 when compared to untreated soil. The maximum stem height and total fresh yield of Jew’s mallow were recorded with the application of 9.52 Mg zeolite ha-1+100% NPK.

Conclusion: It could be concluded that the use of zeolite in clayey and sandy soils improved the soil properties, improved the availability of soil nutrients and consequently decreased the environmental pollution. Also, the obtained results are promising for enhancing the horizontal and/or vertical expansion of agriculture in such problematic soils.
