Abstract
Tomato (Solanum lycopersicum L.) is one of the most important vegetableplants in the world.Root-knot nematodes (Meloidogyne incognita) causing problemsin all growing tomato areas in Egypt. The use of such mineral nutrients is the mostenvironmentally successful method for limiting root-knot nematode damage. In thisstudy seven plant mineral nutrients i.e. calcium sulphate, zinc sulphate, magnesiumsulphate, iron sulphate, potassium sulphate N.P.K(20:20:20) and urea (5g/pot each)separately were evaluated comparing with oxamyl on root-knot nematode (1000second stage juveniles/ pot each) infecting tomato plant cv. Castle Rock undergreenhouse conditions (19±3ºC). Calcium sulphate showed the maximum values inimproving total plant fresh weight (65.0%), plant length (80.2%), shoot dry weight(97.2%) and number of leaves per plant (24.2%), with the highest reductionpercentage in nematode population density that averaged 92.3%, followed by thatof urea application (85.5%), respectively. Rates of nematode build-up under thestress of seven mineral nutrients and oxamyl were adversely affected. Such ratesranged between 0.1 to 1.8 vs 4.2 for nematode alone. Namely, calcium sulphatetreatment had reasonable lower value of reproduction, (0.3) while, that of zincsulphate had the highest one (1.8), whereas oxamyl recorded a lowest rate ( 0.1),respectively. Oxamyl as a systemic nematicide ranked second to calcium sulphatein suppressing nematode population density (88.7%), and ranked first in diminishinggalls and eggmasses numbers with values of 88.2 and 100.0%, respectively.
