Growth and Yield of Three Carrot Plant Cultivar on Different Planting Distance

Abstract

The selling price of high-quality carrot has a higher selling price compared to the low-quality carrot. Setting plant distance and planting superior cultivars can improve yield quality. This study aims to study the interaction of carrot plant cultivars and plant spacing on the growth and yield of carrot plants. The study was conducted in June 2016-September 2016 in Pasirhalang-Cisarua-West Bandung (1,100 m asl). The experimental research method used in this study uses a split-plot design. The main plot is carrot plant cultivars (v1=Kuroda EW Select, v2=New Kuroda, v3=Red Judy) and subplots are spacing (j1=7.5 cm x 7.5 cm, j2=10 cm x 10 cm, j3=12.5 cm x 12.5 cm, j4=15 cm x 15 cm) each experiment unit is repeated three times each. Growth and yield parameters observed were plant height, crown width, plant dry weight, tuber length, and fresh weight of carrot. Data from observations were then analyzed using variance at 5% significance level, and Duncan’s mean difference test at 5% significance level. The results showed that the spacing of 15 cm x 15 cm and cultivar Kuroda EW Select produced the highest growth and yield of carrot plants. The selection of carrot plant cultivars and spacing can increase crop yields.
