Abstract/ Executive Summary:

The experiment was conducted at the Regional Agricultural Research Station, Rahmatpur, Barishal during rabi Season of 1992-1993 and 1993-1994. Three tillage implements such as country plough, BARI plough and power tiller were compared in loamy sand soil at 2, 3, 4, 5 and 6 number of ploughings. There was on significant effect of tillage implements on the yield of potato but the effect of number of ploughings were significant. The highest BCR values were found for 5-6 number of ploughings by country plough and BARI plough and that of 4-5 number of ploughings by power tiller. Considering yield, timeliness of land preparation and economic return, 4 ploughings by power tiller was found to be best tillage system for potato cultivation in loamy sand soil.

Keywords: Potato, Tillage, Number of Passes, Cost of Ploughing

Location: Regional Agricultural Research Station, Rahmatpur, Barishal.

Start Date: 00-11-1992

End Date: 00-02-1994

Program Area: Crop-Soil-Water Management

Commodity: Potato

Objectives:

To find out the effect of tillage operations on potato production.

Methodology:

The experiment was conducted at the Regional Agricultural Research Station, Rahmatput, Barishal during rabi season (Nov.- Feb.) 1992-93 and 1993-94. The land was medium high and the texture of soil was loamy sand. The pH of soil ranged from 6.6 to 7.5 and bulk density was 1.42 g/cc.

Achievement/Findings:

From the above discussion it may be concluded that there is no significant difference among country plough, BARI plough and power tiller on the yield of potato. Number of tilling operations increases yield up to number of ploughings. Ploughing cost by power tiller was found lowest. In preparing the land, up to 5-6 ploughings by power tiller were found economic. Six ploughings by country plough, 5 ploughings by BARI plough and 4 ploughings by power tiller are optimum for potato cultivation in loamy sand soil.
