Effect of Atriplex Halimus with Mineral and Organic Fertilization on the Proportion of Proteins and Soluble Sugars of Potato Tuber in the Salt Stress

Abstract Context: In agricultural areas that suffer from an increase in salinity in the soil or irrigation water, the farmer complains of a lack of yield despite the use of improvement techniques such as fertilization. Therefore, we suggest using a biological method to reduce these forms in the cultivation of halophytic plants. Objective: This work aims to study the effect of Atriplex halimus on proteins and soluble sugars in potato tubers (Solanum tuberosum L.) under salt stress. Methods: After water and soil analysis, we planted the A. halimus In each hole three to four plants of the age of two months in rows between the potatoes, after harvesting the tubers, we dried them, Four samples were taken from all untreated potato tubers Atriplex halimus ( a witness Organic fertilizers and mineral fertilizers (urea and phosphorus)) and treatment with Atriplex halimus ( a witness Organic fertilizers and mineral fertilizers (urea and phosphorus)), then measured the percentage of soluble sugars, based on the phenol method to read the spectrophotometer at the wavelength of 490 nm, also for proteins, first we prepared the reagents and then we measured the absorbance at 750 nm using a spectrophotometer. Resultants and conclusions: The results recorded showing a decrease in soluble sugars in the phosphorus and A. halimus interaction, compared to the other interactions: With regard to proteins, an increase was recorded in the interactions A. halimus urea, A. halimus phosphorus fertilizer, and A. halimus organic fertilizer compared to the other interactions, and this is due to the effect of the culture of A. halimus on the stres saline. Significance: The Atriplex halimus has a major role in reducing the salinity rate in the soil. Experience has proven that the cultured of Halophyte plante with potatoes and the addition of fertilizers, especially phosphorous and urée fertiliser, lead to improving the production observed from the lack of salt stress represented by the increase in proteins and the decrease in sugars in the potato tuber
