GROWTH AND YIELD OF QUINOA (Chenopodium quinoa) AS AFFECTED BY SOWING DATE

Abstract

A field experiment was carried out at the research field of Sher-e-BanglaAgricultural University, Dhaka during the period of November to May, 20172018

to study the effect of variety and sowing date on growth and yield ofquinoa. The experiment comprised of two factors; Factor A: Variety (2) viz. Titicaca (V 1 ) and Vikinga (V 2 ) and Factor B: sowing date (5) viz. S 1 (Nov-10),S 2 (Dec-10), S 3 (Jan-10), S 4 (Feb-10) and S 5 (Mar-10). The experiment was laidout in split-plot design with three replications. Data on different growthparameters, yield attributes and yield were significantly varied for differentparameters. The highest plant height (63.75 cm), highest fresh straw weight ofplant -1 (23.47 g) and (372.54 kg ha -1 ) , dry straw weight of plant (2.65 g), and(31.91 kg ha -1 ), 1000-seed weight (2.04 g) seed weight plant -1 (3.16 g) and(52.22 kg ha -1 ) and husk weight (17.13 kg ha -1 ) was found from Titicaca variety.The sowing date resulted higher plant height (72.83 cm), highest fresh strawweight of plant -1 (36.67 g) and (614.31 kg ha -1 -1 ), dry straw weight of plant (4.13g) and (69.12 kg ha -1 ), 1000-seed weight (2.58 g), seed weight plant (7.47 g) and (180.01 kg ha -1 ) and husk weight (42.46 kg ha -1 -1 ) was obtain from V 1 . Highest branch No. (25.88) provide by V 1 S 3, Higher inflorescence No. (31.46)and inflorescence diameter (14.41 cm) in V 2 S 2. From the above results it was appeared that Titicaca with sowing date November

provided the best yieldattributes and yield of quinoa. -1 S 1
