Abstract/ Executive Summary:

The present experiment was conducted at the research field of Patuakhali Science and Technology University (PSTU), Patuakhali to evaluate the Performance of hybrid boro rice (genotypes) in coastal area of Bangladesh. The experiment consisted of five rice varieties as treatment such as Arize Tej, Tea Sakti, Shathi and BRRI Dhan 28. Data were collected on morphological characters such as plant height, number of leaves plant^-1 and leaf area hill^-1, growth characters such as leaf area index (LAI), crop growth rate (CGR) and relative growth rate (RGR), yield and yield components such as number of effective tillers hill^-1,number of non effective tillers hill^-1, panicle length, number of filled grains panicle^-1, number of unfilled grains panicle^-1, 1000 grain weight, grain yield, straw yield, biological yield and harvest index (%) were recorded. The experiment was laid out in a completely randomized block design (RCBD) with three replications. The collected data were analyzed statistically and means were adjudged by DMRT at 5% level of probability. Among the five varieties the Arize Tej gave the highest performance. From the above investigated results, it was observed that the Arize Tej was the most efficient for better growth and higher yield of hybrid boro rice genotypes grown in coastal area of Bangladesh.

Keywords: Performance; Hybrid, Rice; Coastal area

Location: Patuakhali Science and Technology University, Patuakhali

Start Date: 00-12-2011

End Date: 00-05-2012

Program Area: Variety and Species

Commodity: Rice

Objectives:

The growth performance of five hybrid boro rice genotypes in coastal region of Bangladesh.

Methodology:

An experiment was conducted at the research farm of Patuakhali Science and Technology University, Patuakhali during the period from December, 2011 to May, 2012. The research farm is located at 22⁰37´ N latitude and 89⁰10´ E longitudes. The area is covered by Gangetic Tidal Floodplains and falls under Agroecological Zone “AEZ–13”. The area lies at 0.9 to 2.1 meter above mean sea level (Iftekhar and Islam, 2004). The experiment was laid out in a Randomized Complete Block Design (RCBD) with three replications. The experiment consisted of five rice varieties as treatment such as Arize Tej, Tea, Sakti, Shathi and BRRI Dhan 28. The urea, triple super phosphate (TSP), muriate of potash (MP) fertilizers were applied in the experimental plots at the rate of 86, 135, 65 kg ha^-1, respectively. The entire amount of triple super phosphate, muriate of potash were broadcast and incorporated into the soil at final land preparation. Whole urea was applied in three equal splits at 15 days after transplanting, active tillering and panicle initiation stages (FGR, 2012). The seedling of boro rice was transplanted in the research field on January 05, 2012. The distances between row to row and plant to plant were 20 and 15 cm, respectively. Morphological characters such as plant height, number of leaves plant^-1 and leaf area hill^-1, growth characters such as leaf area index (LAI), crop growth rate (CGR) and relative growth rate (RGR), yield and yield components such as number of effective tillers hill^- ¹,number of non effective tillers hill^-1, panicle length, number of filled grains panicle^-1, number of unfilled grains panicle^-1, 1000 grain weight, grain yield, straw yield, biological yield and harvest index (%) were recorded. The data obtained from experiment on various parameters were statistically analyzed in MSTAT–C computer program (Russel, 1986). The mean values for all the parameters were calculate and the analysis of variance for the characters was accomplished by Duncan’s Multiple Range Test (DMRT) and the significance of difference between pair of means was tested by the Least Significant Differences (LSD) test at 5% levels of probability (Gomez and Gomez, 1984).
