The role of spray application of three inorganic fertilizers MnSO₄, ZnSO₄ and CaCl₂ at three concentration each viz: 50, 100 and 150 mg/l of the first two elements and 100, 200 and 300 mg/l for the latter fertilizer three times at one week interval in comparison with oxamyl at the recommended dose (0.39/plant) on development and reproduction of M. incognita infecting tomato plants cv. Castle Rock and plant growth was studied under greenhouse conditions (29±7ºC). Obviously all tested nutrient minerals with their concs. significantly improved plant growth parameters and reduced nematode criteria, respectively as well to great extent. Among the tested inorganic fertilizers, CaCl₂ at 200 mg/l/plant overwhelmed other treatments, followed by that of  MnSO₄ at 150 mg/l in the increments values of plant growth parameters such as shoot dry weights (30 and 21.1%). whereas, ZnSO₄  at 100 mg/l application had the lowest value (9.6%) in this respect, respectively. Similar trend was noticed regarding reduction of nematode criteria such as population density (90.8, 90.7 and 90.2%) respectively. Likewise, nematode multiplication was also affected by the tested nutrient elements performing the above trend, where CaCl₂ at 200 mg/l and ZnSO₄ at 50 mg/l/plant represented of minimum and maximum values that averaged 0.13 and 0.16 vs 1.39 for nematode alone respectively. N, P, K concs., chlorophyll and total phenol contents in leaves of tomato either infected with M. incognita or not as influenced by foliar spraying of the tested inorganic fertilizers were reported and discussed.
