YIELD AND YIELD CONTRIBUTES OF CORIANDER (CORIANDRUM SATIVUM L.) AS INFLUENCED BY SPACING AND VARIETY

Abstract

A field experiment on coriander (Coriandrum sativum L.) taking two varieties (BARI Dhonia 1 and Faridpur local) and six spacing (20 cm x 10 cm, 25 cm x 10 cm, 30 cm x 10 cm, 20 cm x 15 cm, 25 cm x 15 cm and 30 cm x 15 cm) was conducted to find out the effect of variety and spacing on yield attributes and seed yield of the crop at Sher-e-Bangla Agricultural University farm, Dhaka, Bangladesh during the rabi season of 2011-2012. The experiment was laid out in randomized complete block design (RCBD) with three replications. Varieties, spacing and their combination showed significant variation in yield attributes and seed yield of coriander. Both the varieties produced identical results in respect of most yield attributes and seed yield. The variety BARI Dhonia 1 gave higher values in respect of number of umbels plant-1, number of seeds umbel-1 and umbellate-1 and 1000 seed weight compared to Faridpur local. The wider spacing of 30 cm x 15 cm produced the maximum plant, number of secondary branches plant-1, number of seeds umbel-1 and umbellate-1 and seed yield plant-1 compared to the closer spacing (20 cm x 10 cm). The spacing of 30 cm x 10 cm produced the maximum seed yield (2.01t ha-1) which was statistically similar with 20 x 15 cm (1.99 t ha-1), 25 cm x 10 cm (1.94 t ha1 ) and 20 x 10 cm spacing (1.95 t ha-1). The variety Faridpur local in combination with 30 x 10 cm spacing gave the highest seed yield (2.16 t ha-1) identical with 25 cm x 10 cm spacing with the same variety Faridpur local (2.10 t ha-1 ).
