Abstract:
Background and Objective: Salinity is a serious agro-environmental problem which limiting plant growth and productivity especially in arid and semi-arid regions of the world. Most of the developing countries suffer from shortage of cultivated area and lack of water resources as well as increasing salinity of agricultural land as a result of climate changes. So growing non-traditional crops such as halophytic plants is a promising solution to solve problems of saline habitats. Methodology: For this concern, two field experiments were carried out during 2014 and 2015 seasons at the Model Farm of National Research Centre, El Tour, South Sinai to study the impact of organic fertilization with farmyard manure (5 t fed–1), chicken manure (5 t fed–1) and foliar application with KNO3 (2%), Zn-EDTA (100 ppm) as well as their interaction on biomass production, biochemical composition of Spartina patens. Results: Organic treatment (chicken manure 5 t fed–1) significantly increase the fresh weight of different cuttings, total productivity, chlorophyll a+b, crude protein, potassium content and K/Na ratio compared with control treatment or with farmyard manure. On the other hand, organic treatment (Farmyard manure or chicken manure) decreased the contents of soluble carbohydrates, sodium, calcium and proline as well as succulence, osmotic potential values and Ca/Na ratio. Foliar spraying with KNO3 significantly increase fresh weight of different cuttings, total productivity, chlorophyll a+b, crude protein, potassium content and K/Na ratio compared with tap water or Zn-EDTA. Meanwhile foliar spray with tap water significantly increase the contents of soluble carbohydrates percentage, sodium, calcium and proline as well as the values of succulence, osmotic potential and Ca/Na ratio. As for the interaction effect between organic treatment and foliar treatment, data show that, the highest values of fresh weight cuttings, total productivity, chlorophyll a+b, crude protein percentage, potassium content and K/Na ratio were recorded in plants fertilized with chicken manure (5 t fed–1) and sprayed with 2% KNO3. Furthermore, plants sprayed with tap water without organic manure produced the highest content soluble carbohydrates percentage, sodium, calcium and proline as well as succulence and osmotic potential. Conclusion: It can be recommended the applications of both organic fertilizer (5 t fed–1) and foliar spray with K+ and Zn-EDTA under saline sandy soil conditions.
