The importance o fplanting pot marigolds (Calendula officinalis L.) in degraded public spaces from the agroecological and economic perspective

Abstract

The purpose of this paper is to analyse the introduction of certain plant species such as pot marigolds (Calendula officinalis L.) into neglected and predominantly urban spaces in the Republic of Serbia. The research was based on the results obtained in a two-year experiment conducted in the vicinity of the Novi Sad-Backa Palanka road. The primary objective of the experiment was to examine the behaviour of pot marigolds in poor-quality and neglected soils, with minimum cultural practices, in order to obtain novel plants in such adverse environments, which could be subsequently marketed in Serbia. The experiment commenced in 2014 by planting pot marigolds in plots previously cleared of weeds by mechanical tilling. In the spring of 2015, pot marigold seedlings, i.e. the first generation of plants obtained from the plots created in 2014, were planted in weed-free plots. The measurements were performed in three replicates from 10 October to 10 December 2015 in order to determine the number of volunteer plants, which could be further improved in nursery production and subsequently marketed in Serbia. The results obtained indubitably indicate that this and prospective studies exert positive ecological, agricultural and economic effects on a vast range of potential users.

U ovom radu autori analiziraju uvođenje sadnje pojedinih biljnih vrsta, na primeru biljke nevena (Calendula officinalis L.) i to na zapuštenim površinama, pretežno gradskim parcelama u Republici Srbiji. Za izradu ovog rada korišteni su dvogodišnji eksperimentalni rezultati koji su dobijeni na prostoru oboda Grada Novog Sada, u neposrednoj blizini saobraćajnice na putu Novi Sad-Bačka Palanka. Prvenstveni interes autora je bio da se eksperimentalno ispita ponašanje pomenute biljne vrste, koja je sađena u lošim i zapuštenim zemljištima, uz minimalnu mehaničku pripremu zemljišta, sa ciljem dobijanja novih biljaka koje nastaju na takvom prostoru, a koje se mogu dalje prodati na tržištu, pre svega Republike Srbije. Eksperiment je počeo tokom 2014., nabavkom biljaka koje su posađene na zemljištu koje je prethodno mehanički očišćeno od korovskih biljaka, da bi bio nastavljen tokom 2015. Početkom proleća naprethodno očišćenom zemljištu od korova posađene su mlade biljke nevena (Calendula officinalis L.), koje su u suštini prva generacija prethodno sađenih biljaka. Rezultati merenja su vršeni u tri navrata i to u intervalu od 10.10. do 10.12.2015., sa ciljem utvrđivanja broja samoniklih biljaka koje se mogu dalje doraditi u rasadničkoj proizvodnji. Cilj ovakve dorade bi bio prodaja, pre svega na tržištu Republike Srbije. Dobijeni rezultati jasno ukazuju, da ova i slična ispitivanja imaju ekološko-agrarni i ekonomski značaj. Krajnji efekti su pozitivni i ispoljavaju svoje delovanje na širi krug mogućih korisnika.
