EFEECT OF VARIETY AND NITROGEN LEVELS ON THE FOLIAGE YIELD OF CORIANDER (Coriandrum sativum L.)

Abstract

A field experiment on coriander (Coriandrum sativum L.) was conducted at the Agricultural Botany farm of Sher-e-Bangla Agricultural University (SAU), Sheree-Bangla Nagar, Dhaka during the rabi season of December 2012 to January 2013 to find out the appropriate variety and suitable nitrogen dose for the maximum foliage yield of the crop. The experiment was laid out in factorial randomized complete block design with three replications. The treatment consisted of five varieties, namely, Champak super one, Rosina, Green Beauty, Multicut 5X and Faridpur local, and four nitrogen doses viz. control (no nitrogen), 30, 60 and 90 kg Nha-1. The treatment effects were found significant in most of the parameters studied. The maximum plant height, plant spread, number of leaves plant-1, length of the longest leaf; single plant weight and fresh plant weight m-2 were obtained from the variety Rosina and 90 kg N ha-1. Application of 60 and 90 kg N ha-1 gave statistically similar results in respect of the above foliage yield contributing parameters. The variety Rosina and 90 kg N ha-1 independently as well as in combination gave the highest foliage yield of coriander. The nitrogen doses of 60 kg and 90 kg ha-1 were identical in producing foliage per hectare. The performance of the variety Faridpuri or Local was the poorest in terms of foliage yield and yield contributing characters.
