Abstract/ Executive Summary:

The experiment was conducted at the Agronomy Field of Sher-e-Bangla Agricultural University (SAU), Dhaka during July to November 2005 to study the performance of newly developed Subash, promising aromatic genotypes under different transplanting dates along with BRRIdhan38. The experiment consists of two factors viz. A: Cultivar: Subash 1, Subash 2, Subash 5 and BRRIdhan38, B: Transplanting date: 15 July, 1st August, 15 August and 1st September. The experiment was laid out in split plot design with three replications. Experimental result showed that variety/genotypes and transplanting date individually had significant effect on the agronomic attributes. The results reveled that among the variety/genotypes Subash 1 gave the highest yield (3.95 t ha^-1) but it was lowest in Subash 2 (3.47 t ha^-1). 1st August transplanting gave the highest grain yield (4.13 t ha^-1) and lowest grain yield was found in 1st September transplanting. The combined effect of variety/genotypes and date of transplanting had also significant effect on yield and yield contributing characters. Subash 1 and BRRI dhan38 planted on 1st August showed highest yield attaining good yield contributing characters.

Start Date: 00-07-2005

End Date: 00-11-2005

Program Area: Variety and Species

Commodity: Rice

Objectives:

1. To evaluate the yield performance of transplanted aromatic rice in respect to planting time.

Methodology:

The research work was conducted at the Agronomy research field, Sher-e-Bangla Agricultural University, Dhaka during July to December, 2005. The experiment consists of two factors viz. (A) Cultivar: Subash 1(C₁), Subash 2(C₂), Subash 5 (C₃), and BRRI dhan 38 (C₄); (B) Transplanting date: D₁= 15 July, D₂= 1st August, D₃= 15 August, D₄= 1st September. The experiment was laid out in split plot design where the cultivars were assigned in main plots and date of transplanting in sub-plots. The unit plot size was 4m X 2.5m. Thirty days old seedlings were transplanted in different dates maintaining the spacing of 20cm X 15cm. The experiment was replicated thrice. The land was fertilized with Urea, TSP, MP, Gypsum and Zinc Sulphate @ 270-130-120-70-10 kg ha^-1 respectively. The entire amount of TSP, MP, Gypsum and Zinc Sulphate was applied at final land preparation. The entire amount of Urea was top dressed in three equal installments at 15, 30 and 45 days after transplanting (DAT). All intercultural operations were performed in time as per requirement of the crop. Plot-wise grain and straw yields were recorded following the harvesting of the central 3 m² area plot^-1 and converted to t ha^-1 and expressed at 14% moisture content basis. Crops were harvested at maturity when 80% grain become in golden colour due to the variation of planting dates and variation of life cycle of rice genotypes/varieties. Collected data were analyzed statistically by using the analysis of variance technique and the significance of mean difference were analyzed by DMRT.

Achievement/Findings:

The combined effect of variety and date of transplanting was found to be significant for all the parameters. The tallest plant height and panicle length was obtained from BRRI dhan38 with 15 July transplanting and lowest one was found 15 August transplanting with Subash 2 and 1st September transplanting with Subash 1 respectively. The treatment combination of 1st August planting with BRRIdhan38 produced the highest number of total tiller/m², number of total spikelet /panicle, number of effective tillers/m², number of filled grains/panicle and grain yield. The highest straw yield and biological yield was obtained from combined effect of 15 July transplanting with BRRI dhan38. The lowest number of total tiller/m², number of total spikelet/panicle, number of effective tiller/m², number of filled grains/panicle and biological yield was observed from 1st September transplanting with Subash 5 variety/genotypes. However, the lowest grain yield (3.10 t ha^-1) recorded from 1st September transplanting with BRRI dhan38 interaction treatment. Yield decreases more rapidly in BRRI dhan38 from early transplanting date to late transplanting date than other tested varieties/genotypes.
