EFFECT OF NITROGEN ON THE VARIETAL PERFORMANCE ON CORIANDER (Coriandrum sativum L.)

Abstract

Coriander is one of the most important and major spices in Bangladesh as well as world. A field experiment was conducted at the farm of Sher- E- Bangla Agricultural University, Dhaka from November 2018 to February 2019 to examine the effect of nitrogen on the varietal performance on coriander. The experiment consisted of two variety viz. V = BARI Dhonia-1 and V = BARI Dhonia-2 and six levels of nitrogen viz. 0, 20, 40, 60, 80 and 100 kg ha -1 2 . The experiment was laid out in Randomized Complete Block Design (factorial) with three replications. There were 12 treatment combinations in all. The BARI Dhonia-2 produced maximum number of branches per plant, number of umbel per plant, number of seed per plant, 1000 seed weight, seed yield per plot. The highest yield (1432.40 kg ha

-1 ) was obtained from BARI Dhonia-2. The tallest plant and maximum number of leaves plant -1 were recorded at 60 kg N ha -1 followed by 80 kg N ha at different growth stages. Application of 60 kg N ha -1 gave the maximum branches plant , umbellates umbel -1 , seed plant -1 , 1000 seed weight, seed yield plot -1 and seed yield (1691.65 kg ha -1 ). Application of 60 kg N ha -1 coupled with BARI Dhonia-2 gave the maximum seed yield of (1699.98 kg ha -1 ). The highest concentration of N and K in post harvest soil was recorded in the treatment combination of BARI Dhonia-2 with application of60 kg N ha

-1 .
