VALUATION OF NOT CONVENTIONAL SALT WATERS IN DRY CULTURE

Zouaoui Ahmed, S.A. Snoussi

Abstract


In the dry and semi-arid zones, the water requirements of the cultures are raised while the available water presents a strong unfavorable mineralization in irrigation. Our study concerned the culture of tomato, variety “Saint Peter†averagely sensitive to the salinity. Plants were Subdued to two series of solutions (series 1: natural salt waters T1, T2, T3 and series 2: T1C, T2C and T3C corrected salt waters) and a standard nourishing solution noted T4. The addition in nutriments in natural salt waters improved considerably the growth of the plants of tomato which was translated by a smooth running of the photosynthetic processes, and a production of important fresh and dry biomass. So, there is a more important accumulation of proline and soluble sugars in the various parts of the plant which is made in the sense: root stalk-leaf.
