Abstract
An experiment was conducted at Shambat Agricultural farm to study the effect of pesticides residues on soil and potatoplant. Potato was planted on January, 2009 on ridges with a spacing of 70 cm between rows and 10 cm between plants. 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), pH, total nitrogen %, phosphorus (ppm), leaf number and size of tubers. The results revealed that both chemicals affected negatively the vegetative growth of potato and its yield. It was noticed that the yield was generally less due to the effect of the heavy clay soil of Shambat. Addition of Sevin increased the total soil nitrogen and reduced soil organic carbon while the reverse was noticed for Malathion. Both chemicals lowered soil pH, from alkaline to neutral or slightly alkaline. However, they increased soil salinity which in turn affected potato growth and yield.
Highlights
The excessive use of pesticides results in a great damage to the ecosystem
The results showed the negative effect and poor growth of wheat
A field experiment was conducted at the College Farm (380 m. above sea level) to study the effect of two pesticides on the potato growth
Summary
The excessive use of pesticides results in a great damage to the ecosystem. The production is greatly affected by this phenomena and the soil is polluted. Zaki (1978) stated that someAmerican Journal of Experimental Agriculture, 1(4): 226-230, 2011 pesticides might undergo a lot of changes and become more toxic. Khashin (1980) reported the effect of pesticides on plant part. Abdel Hamed (1989) pointed out that the residues might affect the presence of some minerals especially trace elements. The excessive use of pesticides results in a great damage to the ecosystem. The production is greatly affected by this phenomena and the soil is polluted. Soil fumigation with carbon sulphate resulted in manganese and potassium increase. Omer (2001) studied the residues at Fashir district. Addition of sodium nitrite and DDT to the soil decreased the production of ammonia and the change of ammonia to nitrate. He found high amount of pesticides of 0.0156 ppm of Sevin in the soil
