Abstract/ Executive Summary:

We conducted an experiment at the experimental farm of Bangladesh Rice Research Institute, Gazipur during Kharif-1 season to identify alternative direct seeded Aus rice based cropping pattern for upland ecosystem. Single direct seeded Aus rice pattern produced the lowest REY (2.45 t/ha) than the rest of the tested patterns. The direct seeded Aus rice-Edible podded pea pattern produced the highest rice equivalent yield (13.05 t/ha) followed by Aus rice-Bushbean (10.15 t/ha) and DS Aus rice-Chickpea patterns (9.5 t/ha). Moreover, edible podded pea, bushbean and chickpea produced 2.25 t/ha, 0.91 t/ha and 3.33 t/ha crop residues respectively. Results of the study suggested that the upland ecosystem could be diversified and its productivity could be increased by growing edible podded pea, bushbean and chickpea.

Keywords: Direct seeded Aus rice, Cropping pattern and Upland ecosystems

Location: BRRI farm Gazipur

Start Date: 00-00-2005

End Date: 00-00-2005

Program Area: Farming System

Non-commodity: Cropping pattern

Objectives:

To observe the several alternative direct seeded Aus rice based cropping patterns to evaluate their productivity as well as to diversify cropping intensity of upland ecosystem.

Methodology:

We did the experiment at the BRRI farm Gazipur during Kharif-1 season 2005-06. The experimental plots were laid out in RCB design with three replications. BR21 was grown as direct seeded Aus rice followed by nine Rabi crops viz mustard (Tori-7 & SS-75), pea (Faridpuri), edible podded pea, bush bean, chickpea (Nabin), linseed (Nila 1), soybean (Sohag) and sunflower (Kironi). DSR BR21 was seeded on 5 May and all the tested Rabi crops were seeded on 13 November. Fertilizers (kg/ha of N-P₂O₅-K₂O-S-Zn): Tori-7: 100-80-50-30-4; SS-75: 120-80-60-40-4; Pea, Edible podded pea and Bushbean: 30-85-35-20-4; Soybean:30-80-100-20-4; Chickpea:30-90-60-20-4; Linseed: 35-60-30-0-0; Sunflower: 100-100-100-30-4 as per fertilizer recommendation guide (BARC, 1996). All other cultural practices for rice and non- rice crops were followed as per recommendation of BRRI and BARI. For optimum germination of the Rabi crops, irrigation was applied one day after seeding and at 30 days after seeding. All the Rabi crops except bush bean and edible podded pea were harvested at seed maturity whereas edible podded pea and bush bean were harvested at 80 and 71 days after seeding respectively, as green pods. Crop residues yield of all Rabi crops and nitrogen accumulated in the crop residue were recorded. The productivity of the tested cropping patterns have been expressed in terms of rice equivalent yield (REY).

Achievement/Findings:

Yield of direct seeded Aus rice in different cropping patterns ranged from 2.10 to 2.50 t/ha. The rice equivalent yields varied from 2.45 to13.05 t/ha. Single rice pattern produced the lowest grain yield (2.45 t/ha) than the rest of the tested patterns. The direct seeded Aus rice-edible podded pea pattern produced the highest rice equivalent yield (13.05 t/ha). This was followed by DS Aus rice-bushbean cropping pattern (10.15 t/ha) and DS Aus rice-Chickpea pattern (9.5 t/ha). The yield of Rabi crops contributed for achieving of higher total rice equivalent yields in these patterns. Crop residue yield of Rabi crop at harvest indicated that sunflower produced the highest dry crop residue (3.67 t/ha), which was followed by chickpea (3.33 t/ha) and edible podded pea (2.25 t/ha). Linseed cake accumulated the highest nitrogen (60.76 kg/ha) followed by edible podded pea residues (35.10 kg/ha). Results of the present study suggested that the upland ecosystem could be diversified and its productivity could be enhanced by growing edible podded pea, chickpea and linseed after DS Aus rice (BR21).
