Abstract/ Executive Summary:

The study was conducted in the farmers’ field Kodma, Omorpur, Nandigram, Bogra during aman season 13. Self-propelled four rows walking-type rice transplanter was used to transplant seedling. Mechanical transplanting was found faster than manual transplanting. Missing/floating hill was observed insignificant mechanically transplanted field. Fuel consumption of mechanical transplanter obtained 4.4 L/ha. The tiller production sharply increased from 20 DAT and the maximum tillering stage reached in 40 DAT in aman season then it was decreased gradually due to tiller mortality.TP produced 14% higher grain yield in aman season. The total cost of production, gross return, gross margin and BCR were the highest in TP in two seasons. BCR was higher in TP than FP due to higher grain and straw yield. Transplanting rice in TP was profitable than transplanting rice in FP in aman season.

Keywords: Tegra, Tender age seedling, Fuel consumption, Yield, Benefit-cost ratio

Location: Omorpur, Nandigram, Bogra

Start Date: 01-07-2013

End Date: 30-06-2014

Program Area: Farm Mechanization

Non-commodity: Performance

Objectives:

To evaluate the Tegra mechanical transplanting over traditional method
To analyse benefit cost ratio of Tegra method

Methodology:

What is Tegra: TEGRA™ is a solution for rice growers in Asia and Tegra package consisting of planting high quality seeds coated with seed treatment includes seed, raised seedlings, mechanical transplanting, labour for logistics while transplanting, and application of herbicides at the time of transplanting, besides advisory on agronomic practices. Experimental location: The study was conducted in the farmers’ field Kodma, Omorpur, Nandigram, Bogra during aman season 13. The soil type was clay loam (Sand 0%, Silt 3% and Clay 97%), AEZ 25 level Barind tract. The experiment was carried out in randomized complete block design (RCBD) with two treatments, viz. farmers' practice (FP) and machine transplanting (TP). In each season, six farmers within one kilometer radius were selected to conduct this study. Tray preparation: The plastic trays were used to raise mat-type seedlings. Dry soil was filled in tray in such a way that the soil was free from any stone, stubble and grass. Sprouted seeds were spread uniformly over the tray. To protect the seeds from the birds, the mats were covered with straw. Water was sprinkled twice a day by rose cane until there was complete emergence of seedlings. The mat seedlings were ready to transplant when they had 2-3 leaves and 10-12 cm height. BRRI dhan49 was used in the experiment. Sixteen-days old seedling was used in mechanical transplanting whereas, twenty-days old seedling was used in traditional transplanting. Comparative inputs: Seedling were raised in tray using special Syngenta developed media whereas, farmers raised seedling in traditional seedbed. Rice variety, fertilizer rate, cultural practices, disease infestation depended on rice season. Farmers always followed the management practices of TP and applied similar inputs in their land. In aman season, micronutrient magnesium and boron was only applied in TP. Proper care and agronomic services were provided regularly in TP.
