Abstract/ Executive Summary:

The experiment was conducted at west byde of BRRI experimental farm to find out agronomically productive cropping patterns with new varieties for Boro-Fallow-T. Aman cropping pattern. Objective of this study was to find out agronomically productive cropping patterns with new varieties for Boro-Fallow-T. Aman cropping pattern. From this study it was observed that the BR6110/ BRRI dhan31-Fallow-BRRIdhan29/ BR4828 gave higher yield than the other tested pattern of BR6110/ BRRI dhan31-BRRI dhan28/ BR5877/ BR6110.

Keywords: Agronomic productivity, Economic productivity, Cropping pattern

Objectives:

To find out agronomically productive cropping patterns with new varieties for Boro-Fallow-T. Aman cropping pattern.

Methodology:

The experiment was conducted at west byde of BRRI experimental farm to find out agronomically productive cropping patterns with new varieties for Boro-Fallow-T. Aman cropping pattern. The experiment was laid out in a RCB design with three replications. Ten alternative cropping patterns i) BRRI dhan31-Fallow-BRRI dhan28, ii) BR6110-Fallow-BRRI dhan28, iii) BRRI dhan31-Fallow-BRRI dhan29, iv) BR6110-Fallow-BRR Idhan29, v) BRRI dhan31-Fallow-BR4828, vi) BR6110-Fallow-BR4828, vii) BRRI dhan31-Fallow-BR5877, viii) BR6110-Fallow-BR5877, ix) BRRI dhan31-Fallow-BR6110 and x) BR6110-Fallow-BR6110 were tested. This experiment was initiated in 2002 and is being continued. Reported results represents the second season data during 2003-2004. Recommended management practices followed in the experiment.

Achievement/Findings:

Agronomic productivity of different cropping patterns was found to differ significantly. Total grain yield ranged from 8.23 to 10.38 t/ha. Among the patterns, BR6110-10-1-2-Fallow-BRRI dhan29 (10.38 t/ha), BR6110-10-1-2-Fallow-BR4828-54-4-1-4-9 (9.97 t/ha) and BRRI dhan31-Fallow- BR4828-54-4-1-4-9 (10.39 t/ha) produced comparable grain yield but significantly higher than other combinations.
