Abstract/ Executive Summary:

The experiment was conducted at the Bangladesh Rice Research Institute Farm, Gazipur, in boro season to determine the optimum planting date and to select the varieties having high yield potential. Traditional aromatic photoperiod sensitive fine rice varieties; Kalijira, Kataribhog, Chinigura and Badshabhog were transplanted from 10 December and continued up to 25 January, both in 2000 and 2001 years, at an interval of 15 days. Forty-day old seedlings were transplanted spaced at 20 cm x 20 cm. Results exhibited that plant tallness, number of tillers and dry matter increased with the advancement of planting dates. On the contrary, the number of panicles, grains panicle^-1, panicle length, grain yield, straw yield and growth duration decreased with delaying of planting dates. The intermediate short stature plant type of Chinigura exhibited higher number of panicles (300-331 m^-2) and comparatively heavier individual grain (12.25-12.31 g), consequently gave higher grain yield (2.79-3.53 t ha^-1) planted with in December. However, in late planted situation in 10 January Kalijira exhibited higher number of panicles, grains panicle^-1, resulted higher grain yield than the rest of the varieties. Thus, cultivation of traditional aromatic fine rice Chinigura and Kalijira have the potentiality to produced higher grain yield when planted in early December in Boro season.

Program Area: Crop-Soil-Water Management

Commodity: Rice

Objectives:

So, it is important to determine the optimum date of planting and to select fine rice aromatic varieties having high yield potential for growing in Boro season to obtain higher grain yield.

Methodology:

The experiment was done at the Bangladesh Rice Research Institute Farm, Gazipur, during Boro season. Forty-day-old seedlings of traditional aromatic rice Kalijira, Kataribhog, Chinigura and Badshabhog were transplanted started from 10 December, 25 December, 10 January and 25 January both in 2000 and 2001 years, spaced at 20 cm 15 cm by using 2-3 seedlings hill-1 . The treatments were distributed in a split-plot design, placing planting date in the main plot and varieties in the sub plot and replicated thrice. Fertilizers were applied @ 80-60-40-10-4 kg N, P₂O₅, K₂O, S and Zn ha-1 , respectively through urea, triple super phosphate, muriate of potash, gypsum and zinc sulphate during final land preparation except urea. Urea was top-dressed in three equal splits at 15 days after transplanting (DAT), 30 DAT and at 5 days before panicle initiation as per BRRI (2004). The crop field was kept weed free by 2 hands weedings at 20 and 40 DAT of each planting date. The plant height, tiller number and dry matter were measured at different growth stages at 15 day intervals starting from 30 DAT. Five destructive sample hills were collected from each individual plot outside of the harvested area to measure different growth parameters. The plant height was measured and the tillers were counted from the sample hills. The same sample was also used for the dry matter determination drying them in an oven for 72 hours. For grain yield five square meter areas was harvested from the center of the plot. The grain yield was adjusted to 14% moisture content and expressed in ton ha^-1. The straw was dried in the sun until complete drying. Results were made on averaging the values of two years. Data were analyzed and the means were compared using computer package”Irristat” developed by IRRI (IRRI, 1992).

Achievement/Findings:

it may be concluded that it is important to cultivate high yield potential photoperiod sensitive traditional aromatic fine rice varieties having cold tolerance at the early growth stage which may be provided through transplanting them in early December to increase production in Boro season.
