Abstract/ Executive Summary:

The performance 4-walking type mechanical transplanter was evaluated in Boro (2015) season in the farmers’ field at Gosaidanga in Shailkupa upazila under Jhenidah district and at Rashidpur in Mithapukur upazila under Rangpur district. Two treatments, i.e. T₁= Hand transplanting (HT) and T₂ = Mechanical transplanting (MT) were used in the experiment. Fuel consumption of 4-row walking type mechanical transplanter obtained 5.25 litre per hectare. The field capacity and field efficiency of rice transplanter obtained 0.11-0.12 ha/hr and 64-70 percent, respectively. Conventional seedbed preparation required 37-55 man-hr/ha whereas 71-77 man-hr/ha required in mat type seedling suitable for mechanical transplanting. Labor requirement in manual and mechanical transplanting ranged from 123-150 and 9.0-10.5 man-hr per hectare which was 19-22 and 1.65-2.00 percent of total labor requirement in rice cultivation, respectively. Mechanically transplanted plot showed significantly higher grain yield (9-14%) than hand transplanted method due to use of infant seedling and better planting efficiency. The cost of growing mat type seedling for mechanical transplanter obtained 53 percent whereas the cost of raising traditional seedbed obtained 34 percent of the cost of manual transplanting.Mechanical transplanting systems increased yield, improved labor efficiency, ensured timeliness in operation and faster transplanting.

Keywords: Fuel consumption, Labour requirement, Yield, Benefit-cost ratio

Location: Jhenaidah, Rangpur

Start Date: 01-11-2014

End Date: 30-06-2015

Program Area: Farm Mechanization

Commodity: Transplanter

Objectives:

· 1. To evaluate the field performance of mechanical rice transplanter

· 2.To estimate the yield and yield contributing character

· 3.To compare the cost of mechanized cultivation over traditional method

Methodology:

Experimental location: This experiment was conducted in the farmers’ field at Gosaidanga in Shailkupa upazila under Jhenidah district and at Rashidpur in Mithapukur upazila under Rangpur district. Experimental design: The experiment was carried out in randomized complete block design (RCBD) and replicated in six plots. Twelve plots within one kilometer radius were selected to conduct this study. Treatment: Two treatments were used to conduct the experiments, which is T₁ = Hand transplanting (HT) and T₂ = Mechanical transplanting (MT). Inputs were almost similar in both practices. Seedling age was higher in MT than HT. Seedling were raised in tray for mechanical transplanter whereas, farmers raised seedling in traditional seedbed. Micronutrient was applied in both practices. Proper care and was taken and agronomic services was provided regularly in MT and HT. Data on labour requirement, field capacity, missing hill, hill density, tillering dynamics, yield and yield contributing characters were taken and analysed using software Statistix 9.0. Least significant difference was used to compare the means. In order to estimate the production cost, the data on working speed, total time and labor involvement and materials inputs to complete the operation were recorded. Rental charge of the machines was also included in the cost estimation. Land rental value and interest on investment were considered to calculate the total input cost. Price of the produce was collected from the local markets to compute total production cost, gross return, gross margin and benefit-cost ratio.

Achievement/Findings:

Mechanical transplanting increase grain yield, reduce the production costs and improved labor efficiency. It can be concluded that mechanical transplanting method is economic than the manual transplanting method.
