I acknowledge with gratitude the support, advice and encouragement
provided by my supervisor Prof. Mohammed Osman Gafar throughout the
project study. Also I would like to thank my friends for their help and support.
My sincere thanks are extended to my colleagues and staff of the laboratory
at the college for their help, kind gestures and friendly attitude during this
study and thank for abdelateaf. And Special thanks warmly go to my brother
Ahamed.
An experiment was conducted at Shambat Agricultural Farm to study the effect of
two pesticides Sevin and Malathion on soil and plant. Cucumber was planted on
2
November, 2012. Sevin and Malathion pesticides were added at different
concentrations to evaluate their effect on the plant growth and soil.
The measurement taken was plant height (cm), fresh and dry weight (gm), leaf area
(cm2), and number of leaves per plant.
The results revealed that both Sevin and Malathion Pesticides at all the
concentrations dose gave negative effect on height, leaf area, weight and number
of leaves per/ plant, compared with the control.
Soil pH, total nitrogen %, phosphorus (ppm), soil particles size analysis (sand,
silt and clay %), ECe dS/m, CEC cmol (+)kg- 1 and O.C %.The result revealed that
both chemicals affected negatively the vegetable growth of Cucumber except the
ECe of the saturation extract was increased (0.4dS/m before planting and
0.98dS/m)after planting.
However, both chemicals increased soil salinity which in turn affected plant
growth and soil yield.
