IMPACT OF SOME SOIL AMENDMENTS ON PROPERTIES OF SALT AFFECTED CALCAREOUS SOIL AND SALINITY HARMFUL IN TOMATO PLANT (Lycopersicon esculentum)

Abstract

An experiment was carried out in plastic pots under greenhouse condition during (2) successive season to investigate the effect of the organic manures (compost, peat moss, chicken and pigeon manures) or soil conditioners (vermiculite and perlite) on some properties of saline calcareous soil and tomato plant enzymes. The obtained results manifested that application of the aforementioned amendments improved soil aggregates, pH, EC, SP, cation and anion and availability of K. Likewise it decreased the activity of Catalase, Peroxidase and Superoxide dismutase tomato plants. The most beneficial influence of the above-mentioned parameters was observed with addition of peat moss, chicken manure and soil conditioners.
