Abstract/ Executive Summary:

An experiment was conducted in the field laboratory of the Department of Crop Botany, Bangladesh Agricultural University, Mymensingh, to investigate the effect of foliar application of Miyodo on morphology, yield contributing characters and yield of T. aman rice cv. BR-11. The concentrations of Miyodo used were 2 mgL^-1, 3 mgL^-1, 4 mgL^-1 and 5mgL^-1 with a control. The experiment was laid out in a randomized complete block design with three replications. Application of Miyodo by spraying at 45 days after transplanting significantly enhanced plant height, number of tillers and effective tillers, number of leaves and leaf area, size of flag leaf, total dry matter, panicle length, number of total grains and filled grains, 1000-grain weight, grain yield, straw yield, and harvest index. The result showed that the application of 5 mgL-1 Miyodo produced the highest grain yield of BR-11 compared to other concentrations as well as control. However, further study is needed to determine the higher concentration limit of Miyodo in maximizing the growth and yield of T. aman rice cv. BR-11.

End Date: 00-12-2007

Program Area: Crop-Soil-Water Management

Commodity: Rice

Objectives:

a. To assess the effect of Miyodo on morphology, yield contributing characters and yield of T. aman rice cv. BR-11, and

b. To find out the effective concentration of Miyodo for getting higher yield in BR-11.

Methodology:

The experiment was carried out at the Field Laboratory of the Department of Crop Botany, Bangladesh Agricultural University, Mymensingh, from July to December, 2007. One of the most popular transplant aman rice cultivars BR-11 was used as plant material. The concentrations of Miyodo used were 2 mgL^-1, 3 mgL^-1, 4 mgL^-1 and 5 mgL^-1 with a control. The experiment was laid out in a Randomized Complete Block Design (RCBD) with three replications. Healthy rice seedlings of 33 days old were transplanted at the spacing of 15 cm x 20 cm (plant-plant x row-row) on 26th July, 2007. The standard rice cultivation procedure was followed as indicated by BRRI (2005). Foliar application of Miyodo was done at 45 days after transplanting (DAT). The data on number of leaves and leaf area hill-1 were collected at 85 DAT, and other morphological features viz., plant height, number of tillers hill^-1, number of leaves hill^-1, total leaf area hill^-1, flag leaf area and total dry matter, were collected at 105 DAT. At final harvest (117 DAT), plant samples were collected from each plot (2m × 3m) and data on number of effective tillers hill^-1, panicle length, number of spikelets panicle^-1, number of filled and unfilled grains panicle^-1, 1000-grain weight, grain yield and straw yield were collected, and the harvest index was calculated. Collected data were statistically analyzed by using the computer software program MSTAT-C and the difference between means was adjudged by Duncan’s New Multiple Range Test (DMRT).

Achievement/Findings:

From the result, it may be concluded that Miyodo treated rice plant showed better performance in growth, yield and yield attributes. Miyodo at the 5 mgL^-1 might be the suitable concentration for higher yield in BR-11. However, further research is needed with some higher concentrations of Miyodo to find out the suitable concentration to maximize the growth and yield in BR-11. However, further study is needed to determine the higher concentration limit of Miyodo in maximizing the growth and yield of T. aman rice cv. BR-11.
