Influence of different mineral fertilizer solutions concentrations to the initial vegetables growth

Većinu hranjiva biljke usvajaju iz prirode, a mogu biti anorganska ili organska, ovisno o tome potječu li iz minerala zemljine kore ili su produkt razgradnje žive tvari. U poljoprivrednoj proizvodnji osobito su važna makrohranjiva dušik, fosfor i kalij jer ovisno o njihovim zalihama u tlu, nadomještamo ih gnojidbom, kako bi biljke imale ujednačen rast i razvoj te optimalne prinose. Povrće možemo uzgajati na otvorenim površinama, a presadnice najčešće uzgajamo u zatvorenim površinama, plastenicima ili staklenicima uz kontrolu čimbenika rasta. Za postizanje dobrih presadnica važno je imati zdravo sjeme, osigurati dovoljno svjetla, vode, pogodno tlo i optimalnu gnojidbu. U ovom radu je prikazan uzgoj i optimalna gnojidba lisnatog povrća pri uzgoju iz presadnica te trenutna istraživanja koja se bave primjenom mineralnih gnojiva i ulogom folijarne gnojidbe.Most nutritional plants are adopted from nature and may be inorganic or organic, depending on whether they originate from crude earth minerals or are the product of degradation of living matter. In agriculture, macronutrient nitrogen, phosphorus and potassium are especially important because, depending on their reserves in the soil, they are replaced by fertilization so that the plants have a uniform growth, development and optimum yields. Vegetables can be grown on open surfaces and the seedlings are usually grown in closed areas, plastic greenhouses or glass greenhouses under the control of growth factors. To achieve good seedings it is important to have healthy seeds, provide enough light, water, a good soil and optimal fertilization. This paper presents cultivation and optimum fertilization of leafy vegetables in breeding from seedlings and current researches dealing with the application of mineral fertilizers and the role of foliar fertilization
