Abstract:
Two common bean landraces (Phaseolus vulgaris L.), "Trenaria" and "Peja" representing the
indeterminate growth habit were tested in two cultivation systems: monoculture and in
association with maize hybrid NS444 (Zea mays L.). The aim of the research was to find the
advantages of the cultivation system of the common bean populations of indeterminate growth
habit based on performance of physiological growth traits and production elements. The
experiment was conducted during the cultivation season of 2016 and 2017 in the agro-ecological
conditions of Prishtina. Experimental design was random complete block with three replications,
with genotype respectively population, cultivation system and year as main factors and other
sub-factors. The studied parameters were growth traits: Leaf area index (LAI), crop growth rate
(CGR) and net assimilation rate (NAR), as well as yield components: pods number per plants
(PNplant-1
), grain number per plant (GNplant-1
), grain weight per plant (GWplant-1
) and grain
weight per unit area (GWm-2
). Research data were subject of ANOVA variance analysis. The
results of the study showed significant differences between common bean landraces in both
systems and years of cultivation. Landraces in the monoculture system showed better
performance for all studied parameters. Therefore, based on the obtained data, could be
concluded and recommended the cultivation of common bean in Kosovo in the monoculture
cultivation system, because of its advantage in terms of production compared to the system in
association with maize. |
