Abstract/ Executive Summary:

An experiment was carried out at the farm of Bangladesh Institute of Nuclear Agriculture, Mymensingh during the Aman season of 2006 to observe the performances of five advanced rice lines along with a check variety. The advanced rice lines were PNR-381, RD-2586, PR-26305-M-2, TNDB-100 and DM-25 and the check variety was Binadhan 4. The experiment was laid out in a randomized complete block design with three replications. All the growth parameters recorded at different growth stages from 35-65 days after transplanting (DAT) were significantly different among the advanced lines/variety. DM-25 produced the tallest plant and PR-26305-M-2 produced the highest number of total tillers hill^-1, leaf area, leaf dry weight, stem dry weight, total dry matter, leaf area index, crop growth rate and net assimilation rate. Check variety Binadhan 4 produced the maximum relative growth rate. The yields were significantly different among the advanced rice lines/variety at harvest. Among the advanced rice lines/variety, DM-25 produced the highest plant height (125.3 cm). Advanced line RD-2586 produced the highest 1000-grain weight (28.47 g), grain yield (5.18 t ha^-1), straw yield (6.73 t ha^-1) and biological yield (11.91 t ha^-1). Check variety Binadhan 4 produced the highest number of grains in primary rachis branch panicle^-1 (51.8) and grains panicle^-1 (99.4).

Objectives:

1. The present study was conducted to observe the growth and growth efficiency of the advanced rice lines with a check variety.

Methodology:

There were five advanced rice lines viz., PNR-381, RD-2586, PR-26305-M-2, TNDB-100 and DM-25 and one check variety Binadhan 4. Binadhan 4 is a well established high yielding variety of Aman rice. The experiment was laid out in a randomized complete block design with the three replications. The whole field was divided into 3 blocks each containing 6 plots. In total, there were 18 unit plots. The size of a unit plot was 12 m² (4 m × 3 m). Plot to plot distance 50 cm and block to block distance was 1 m. The uprooted seedlings of 28 days old were transplanted in the puddled land with row to row distance 20 cm and plant to plant distance 15 cm. Three seedlings were transplanted in each hill. Two hills from each plot were marked by bamboo sticks excluding two border lines and hills. Growth measures on plant height, leaf area (LA), leaf area index (LAI), leaf dry weight, stem dry weight, total dry matter (TDM), crop growth rate (CGR), relative growth rate (RGR) and net assimilation rate (NAR) were recorded from these two hills at an interval of 15 days from 35 days after transplanting (DAT) to 65 DAT for all the advanced lines/variety. Maturity of crop was determined when about 90% of the grains became golden yellow in colour. Five hills (excluding border hills) were randomly selected from each unit plot and were cut at soil surface for recording necessary data at maturity. After that 20 random hills (excluding border hills) were cut at soil surface from the whole plot at maturity and cut on different dates for different lines/variety. The harvested crop was threshed by pedal thresher and then they (grain and straw) were dried in sunlight and finally cleaned by winnowing. The grain and straw yields data of each plot was taken from these 20 hills. The grain yield was adjusted to 14% moisture content. LAI, CGR, RGR and NAR were calculated by the standard formula. Grain yield was recorded at maturity from the 20 hills. The straw yields of the 20 hills at maturity were dried in sunlight and their weights were recorded. The collected data at harvest were analyzed following the ANOVA-technique and the mean differences were adjudged by the Duncan’s Multiple Range Test (DMRT) as per Gomez and Gomez.

Achievement/Findings:

All the growth parameters recorded at different growth stages from 35-65 days after transplanting (DAT) were significantly different among the advanced lines/variety. DM-25 produced the tallest plant and PR-26305-M-2 produced the highest number of total tillers hill^-1, leaf area, leaf dry weight, stem dry weight, total dry matter, leaf area index, crop growth rate and net assimilation rate. Check variety Binadhan 4 produced the maximum relative growth rate.
