Figure 1 The effect of the foliar fertilizati<strong>on</strong> up<strong>on</strong> the producti<strong>on</strong> in the crop of tomatoes<br />

(UNIREA) from the field (Oradea, 2003)<br />

The significant results of the applicati<strong>on</strong> of foliar manure <strong>on</strong> the tomato field culture are due<br />

to an organic mineral under layer and to its recovery by an extra-radicular applicati<strong>on</strong> of<br />

manure as phase/additi<strong>on</strong>al fertilizati<strong>on</strong>s (three treatments at an interval of 14 days).<br />

In additi<strong>on</strong>, the foliar fertilizati<strong>on</strong>s have de<strong>term</strong>ined a greater number of inflorescences and<br />

fruit <strong>on</strong> the plant, fact that prol<strong>on</strong>ged the period of fructificati<strong>on</strong> and cropping (table no. 2).<br />

From the efficient foliar sorts, in the first place Bi<strong>on</strong>utrifag F and Polyfeed 19-19-19 are<br />

focused at the field tomato culture, because they c<strong>on</strong>tain a balanced representati<strong>on</strong> of<br />

nutriti<strong>on</strong> elements and a superior recovery of the fertilizati<strong>on</strong> <strong>on</strong> soil.<br />
