A study was conducted to evaluate the performance of three cultivars of amaranth at five different levels of N application in respect of yield and yield contributing characters and organoleptic (taste and visual acceptability) test at the Horticultural Farm and Laboratories of Sher-e-Bangla Agricultural University, Sher-e-Bangla Nagar, Dhaka- 1207, during March to June, 2005. Morphological characters like stem color, leaf color, base color, vein color, pubescence and petiole color were recorded. Yield and yield contributing characters like plant height (cm), number of leaves, length of leaves, breadth of lcax cs. petiole length. number or branches and stem girth at 25 1)1\S. 40 DAS and 55 DA~ were noted and per plant weigh;

Considering the sweetness, sourness, crispiness and fibre of amaranth consumers prefer the cultivar Bashpata. The cultivar Bashpata got the top score (2828) based on total acceptability ranking and second score (2548) obtained by BARI danta l while the lowest score recorded in Katua (1652). Among these three cultivars Bashpata was superior to others. However, these three cul ti vars are commercially popular in different regions of the country.

lhe maximum ) icld per hectar (72.1 t/hu) was obtained from Bashputu al 97 kg t\ ha which was closely followed by Katua (65.6 t/ha) and BAIU danta l (34.0 t/ha) at the highest N level l 02 kg/ha.

As such. long term research program should be initiated to generate useful detail

information about optimum level of fertilizers application and superior selection of amaranth cultivar \\ ith quality. I lowevcr, further investigation is suggested to confirm the result of this study since the cultivars were grown in one year only and incorporating desirable traits to improve.

The optimum level of nitrogen fertilizer application was found to be 97 kg N/ha for Bashpata in presence of recommended doses of P205 48 kg, K20 l 20 kg/ha and cowdung 20 t/ha. Yield increased with increasing N level BART danta 1 and Katua showed best

performance at the highest lev cl I 02 i..g N/ha. lherefore further inv estigation is suggested \\ i th higher doses of !\I/ha. Among the three culti vars Bashpnia was superior to in over all consideration.

Present study generated information on productivity of three commercial amaranth cultivars at five levels of nitrogen which may help selection of cultivars, and nitrogen

level for successful commercial production. These as follows:
