Abstract/ Executive Summary:

The experiment was undertaken to evaluate the agro-economic productivity of DS rice based cropping patterns under flat and raised bed systems. Objective of the study was to evaluate the agro-economic productivity of dry seeded (DS) rice based cropping patterns under flat and raised bed systems. Result of the study showed that Dry Seeded Rice (DSR)-Potato-Fallow cropping pattern gave higher Rice Equivalent Yield (REY) compared to Mungbean-DS Aman-Wheat and Fallow-DS Aman-Mungbean sequences.

Keywords: Bed systems, Agronomic and economic productivity, Rice

Location: BRRI experimental farm, Gazipur

Start Date: 01-07-2003

End Date: 30-06-2004

Program Area: Farming System

Non-commodity: Cropping pattern

Objectives:

To evaluate the agro-economic productivity of dry seeded (DS) rice based cropping patterns under flat and raised bed systems.

Methodology:

The experiment was undertaken to evaluate the agro-economic productivity of DS rice based cropping patterns under flat and raised bed systems. The experiment was conducted at east byde of the BRRI experimental farm in a factorial RCB design with three replications. Three cropping patterns, DS Aus–Potato–Fallow, Mungbean–DS Aman–Wheat and Fallow–DS Aman–Mungbean were placed under flat and raised bed systems. The experiment was initiated in 2002.Other management practices followed for this experiment are as per recommendation.

Achievement/Findings:

The total productivity of different cropping patterns was compared in terms of rice equivalent yield (REY), which differed significantly among the tested patterns but the interaction effect between establishment methods and cropping patterns was not significant. The highest REY was obtained from the pattern DS Aus–Potato–Fallow (10.43 t/ha) followed by Mungbean–DS Aman–Wheat (8.26 t/ha) and Fallow-DS Aman-Mungbean (5.53 t/ha).
