Greenhouse energy consumption for tomato and cucumber seedlings production

Abstract

Greenhouse production is most energy consuming branch in agriculture and in same time with lowest energy efficiency. Concerning the fact that energy input in greenhouse production has a highest share in product market price more detailed energy analysis must be taken. In this paper energy analysis of tomato and cucumber seedlings production is given. Tomato and cucumber seedling were produced in double plastic covered tunnel. Energy consumption and energy productivity per seedling were calculated.

Proizvodnja povrća u zaštićenom prostoru predstavlja granu poljoprivrede sa najvećom potrošnjom energije i niskom energetskom efikasnošću. Utrošena energija u proizvodnji povrća čini najveći deo u strukturi cene koštanja gotovog proizvoda. Otuda i potreba da se detaljnije ispitaju svi energetski inputi, kako bi se povećala energetska efikasnost proizvodnje i samim tim smanjila cena gotovog proizvoda. U ovom radu su definisani energetski inputi (direktni i indirektni) u proizvodnji rasada paradajza i krastavca i prikazana je potrošnja energije za datu biljnu proizvodnju.
