Development of Alternate Cropping Pattern Potato/maize-t.aman Rice Against Maize -fallow–t.aman Rice

Chief Scientific Officer & Head, OFRD and Relevant Scientists of OFRD

Abstract/ Executive Summary:

A field trial was conducted at the farmers' field of Sherpur MLT Site (AEZ 4), Bogra during 2013-14 to fit potato in the Maize-Fallow-T.Aman cropping pattern and to increase cropping intensity. There were two treatments i.e, F: Existing cropping pattern (Maize-Fallow-T.Aman rice) and FA: Alternate cropping pattern (Potato/Maize-T.Aman rice). Seeds of maize were sown as a relay after 30 days of potato planting in Potato/Maize-T.Aman rice cropping pattern. Higher rice equivalent yield, gross return and gross margin were obtained from alternate cropping pattern over existing cropping pattern due to additional yield of potato.

Keywords: Alternate pattern (Potato/Maize-T.Aman rice), Existing pattern (Maize-Fallow-T.Aman rice) , Cropping intensity, Rice equivalent yield

Location: Sherpur MLT Site (AEZ 4), Bogra

Start Date: 00-00-2013

End Date: 00-00-2014

Program Area: Farming System

Commodity: Potato, Maize, Rice

Objectives:

To study inclusion possibility of potato in the Maize-Fallow–T.Aman rice cropping pattern in the Bogra region.

Methodology:

The trial was conducted at the farmers' field of Sherpur MLT Site (AEZ 4), Bogra during 2013-14. The experiment was laid out with six dispersed replications. There were two treatments i.e, F: Existing cropping pattern (Maize-Fallow-T.Aman rice) and FA: Alternate cropping pattern (Potato relay Maize-T.Aman rice). The unit plot size was 12m x 10m. Potato (var. BARI Alu-8) were planted on 28-30 November 2013 at 60cm ×25cm spacing. Maize (exotic var. Decalb-981) were sown as a relay 30 days after potato planting on 28-31 December 2013 in alternate cropping pattern whereas in existing pattern maize seeds were sown in line on 22 November-06 December 2013. The spacing of maize was 75cm x25cm in both treatments. Potato was harvested on 22 February to 05 March, 2014. Sole maize was harvested on 1-11May 2014 and maize in alternate cropping pattern was harvested on 25 May-03 June 2014. In T.Aman rice, thirty days old seedlings (BRRI dhan 49) were transplanted on 5-15 August 2014 at 20cm×15cm spacing. The crop was harvested on 18-24 November 2014. Plant protection measures for the crops were taken as required. Intercultural operations were done as and when required. Data on yield and yield contributing characters of the crops were recorded carefully. The yield per plot was recorded and converted into yield per hectare. The cost and return analysis was calculated on the basis of prevailing market price of the commodities.
