Abstract/ Executive Summary:

Walking type mechanical rice transplanter was tested in different project location during Boro/2012 season to evaluate the field performance. During test, flexible plastic tray (58 x 28 x 2.5 cm) was used to raise seedling for the transplanter. Yield performance of rice transplanting by mechanical rice transplanter were compared with hand transplanting method. In hand transplanting plot, farmer’s seedling of the same variety BRRI dhan28 and BRRI dhan29 was used. Average yield of the machine transplanting plot and hand transplanting plot were 6.42 ton/ha and 6.28 ton/ha. During evaluation, average speed (m/sec), field capacity (deci/hr), fuel required (l/hr), transplanting width (cm), no. of plants per hill, no. of hill per m², missing hill per m², floating hill per m², buried hill per m² and damaged hill per m² were found 0.82, 66.27, 0.92, 120, 3-5, 20, 1.36 0.73, 0.45 and 0.82 respectively.

Start Date: 01-07-2011

End Date: 30-06-2012

Program Area: Socio-economic and Policy

Commodity: Transplanter

Objectives:

To evaluate the field performance of mechanical Rice Transplanter in different locations of the country.

Methodology:

During test, flexible plastic tray (58 x 28 x 2.5 cm) was used to raise seedling for the transplanter. 22-28 days older seedling with 3-4 leaves was used in this experiment. Land was prepared and leveled by power tiller. After land preparation, the field was kept two days for soil settlement. 0.5 cm standing water was maintained during field operation. Seeds were soaked into fresh water for 24 hrs and stir them. After 24 hours, the shocked paddy was kept in warm condition one day for sprouting and then sows in the tray for seedling. Mechanical rice transplanter, seedling raised on tray and polythine sheet, scale, rope, tape, stopwatch, calculator, weight balance etc were used during the study. • Varieties : BRRI dhan29 and BRRI dhan28 • Seedling age : 20 to 28 for machine transplanting and 40 days for hand transplanting • Spacing: 30 ?15 cm for machine and 20 x 15 cm for hand. During performance study in different locations, the following treatments were applied: • T₁ = Mechanical transplanting • T₂ = Manual transplanting Fertilizer and management practices were the same for all treatments. Data were collected: • Performance parameters of the mechanical rice transplanter • Yield and yield components

Achievement/Findings:

Average yield of the machine transplanting plot and hand transplanting plot were 6.42 t/ha and 6.28 t/ha respectively. During evaluation, parameters of rice transplanter on average speed (m/sec), field capacity (deci/hr), fuel required (l/hr), transplanting width (cm), no. of plants per hill, no. of hill per m², missing hill per m², floating hill per m², buried hill per m² and damaged hill per m² were 0.82, 66.27, 0.92, 120, 3-5, 20, 1.36 0.73, 0.45 and 0.82 respectively.
