The experiment was conducted at the Bangladesh Institute of Nuclear Agriculture (BINA) farm, Mymensingh during 17 December 2006 to May 2007 in the Boro season. The experimental land was sandy loam in texture having soil pH 6.8. The experimental materials such as seeds for the experiment were collected from the Agronomy Division and Plant Breeding Division of BINA, Germplasom centre of BRRI and Agronomy Farm of BAU. The unit plot size was 4.0 m x 2.5 m. The plots of aromatic and non-aromatic fine rice were fertilized with N, P, K, S, Zn at the rate of 135, 39, 67, 29 and 1.8 kg ha-1, respectively according to the fertilizer recommendation guide (BARC, 2005). The whole amounts of triple super phosphate, muriate of potash, gypsum and zine sulphate were applied to the soil at the time of final land preparation. Urea was applied in three equal splits. One split of urea was applied with other fertilizers as basal dose and the other two splits were applied at 21 and 45 days after transplanting (DAT). The experiment was laid out in a Randomized Complete Block Design with three replications. The average value of daily maximum temperatures during the period of December 2006 to May 2007 was 26.22, 23.64, 24.41, 29.13, 30.44 and 33.330C, respectively. A total of 33 aromatic and non-aromatic fine rice varieties were evaluated in this study. The varieties were as follows; BRRI dhan38, BRRI dhan34, BRRI dhan37, Jesmin, Chiniatab, Chinisagar, Ukunimadhu, Kalobhough, Kalizira, Dudhsar, Jumadhuma, Binadhan-4, Binasail, Basmati, Kasmiribasmati, Chikonlal, Kala manik, Lalmoi, Lalgilona, Minikichi, Maharani, Marichbati, Pulashi, Sharisaful, Surjamukh, Sonamukhi, Tripunachinal, Chinikahai, Banajira, Kataribhough, Awnless Minicat, Awn Minicat, Kamonisail. Only selected healthy seedlings were transplanted in the experimental plots on 7 February 2007 in 20 cm apart line maintaining a distance of 15 cm from hill to hill with three seedlings hill-1. Intercultural operations and pesticide application were done as and when necessary. From each plot, 10 hills (excluding border hills) were selected from an inside row for collecting different data at 30 DAT, 60 DAT and 90 DAT. Each plant sample was separated from leaf as their area was measured with the help of a portable area meter (Model Fx-3000 Japan). Just after transplanting, 10 hills were randomly selected and tagged for measuring plant height, total tillers, total dry matter production and chlorophyll contents of leaf. Chlorophyll content of leaves were determined with SPAD meter. During harvest, 10 hills were again randomly selected from plots excluding border hills and from the hills data on yield contributing characters were collected. Grain and straw yields were sun dried and the weight of grains was adjusted to 12% moisture content. Grain and straw yields were then converted to t ha-1. Data were analyzed statistically using “Analysis of Variance” technique and differences among treatments means were adjudged by Duncan’s Multiple Range Test (DMRT).
