Abstract/ Executive Summary:

The study was conducted in order to investigation the relationship between grain yield with the morphological parameters of five local and three modern aromatic rice varieties. The varieties Kataribhog, Radhunipagal, Chinigura, Badshabhog, Kalizera, BRRI dhan34, BRRI dhan dhan37 and BRRI dhan38 were transplanted. All the parameters varied significantly in different aromatic rice varieties. Among the aromatic rice varieties the highest grain yield was obtained from BRRI dhan34 which identically followed by Kataribhog. The highest plant height was observed in Chinigura which statistically similar to Kataribhog. The highest number of fertile tillers hill^-1 was observed in BRRI dhan37 and it was identically followed by Radhunipagal, Badshabhog, Chinigura, BRRI dhan38 and the lowest fertile tillers hill^-1 was obtained from Kalizera which was statistically similar to Kataribhog. The highest number of grains panicle^-1 was found in BRRI dhan34 and that was the lowest in BRRI dhan38. Maximum 1000 grain weight was observed in BRRI dhan38. In respect of yield BRRI dhan34 and Kataribhog are suitable for Dinajpur region in Bangladesh during T. aman season.

Keywords: Morphological attributes, Agronomical attributes, Aromatic rice varieties

Location: Hajee Mohammad Danesh Science and Technology University farm, Dinajpur, Bangladesh.

Start Date: 00-00-2004

End Date: 00-00-2004

Program Area: Variety and Species

Commodity: Rice

Objectives:

To study the effect of local and modern varieties of aromatic rice on their yield performance .

Methodology:

The experiment was conducted at Hajee Mohammad Danesh Science and Technology University farm, Dinajpur, Bangladesh during aman season of 2004. The experimental site was a medium high land with sandy loam soil having a pH value 6.0. The experiment was laid out in a RCBD with three replications. Five local and three modern aromatic rice varieties namely, Kataribhog (V₁), Radhunipagal (V₂), Chinigura (V₃), Badshabhog (V₄), Kalizera (V₅), BRRI dhan34 (V₆), BRRI dhan37 (V₇) and BRRI dhan38 (V₈) were used in this study. The unit plot size was 4.0x2.5 m. The unit plots were uniformly fertilized as per recommendation with urea, TSP and MP at the rate of 120, 50, 60 kg ha^-1 as source of N, P and K, respectively. All P and K fertilizer were applied as basal dose during final land preparation. Urea was top dressed in 2 equal splits at 20 and 45 days after transplanting. All other cultural practices were done uniformly as and when required. The 30 days old seedlings were transplanted at a spacing of 20 x 15 cm using 3 seedlings hill^-1. At harvest, 10 hills from each plot were taken out randomly to record yield parameters and the whole plots harvested to obtain grain and straw yields. Data were analyzed followed the ANOVA technique and mean differences adjudged with Duncan’s Multiple Range Test.

Achievement/Findings:

Kataribhog gave the highest straw yield (8.9 t ha^-1) and the lowest straw yield (5.8 t ha^-1) was obtained from Kalizera identically followed by BRRI dhan37 and BRRI dhan38. Panicle length differed significantly in aromatic rice varieties. Maximum panicle length was found by BRRI dhan38 (24.14 cm) and minimum panicle length. Positive linear relationship of panicle length with the number of spikelets panicle^-1. It could be concluded that BRRI dhan34 and Kataribhog are suitable in Dinajpur region in respect of yield.
