Plant population and cultural practices on yield of bell peppers (Capsicum annuum L.)

A field trial at the Experimental Field of the Biotechnical Faculty in Ljubljana was carried out in 2004 growth season on bell pepper (Capsicum annuum L.) cultivar Bianca F1 to investigate the interactive effect of different plant densities (22, 000 ; 16, 500 and 10, 000 plants/ha) with an in-row spacing of 15, 20, or 30 cm between plants in rows 30 cm apart and different mulch system (PE black mulch, PE white mulch and bare soil) on yield and quality attributes. Yield component analysis indicated that the fruit size was larger on mulching soil (irrespective of mulch colour) in comparison to bare soil at all population densities. The results revealed that PE black mulch and PE white mulch significantly increased fruit lenght, fruit width and fruit weight which are indirectly related to yield. In addition, results suggest that decreasing plant density significantly reduced the marketable fruit yield. Additionally, use of PE black or PE white mulch generally resulted in earlier and higher yield at the firs harvest compared to plants grown on bare soil.
