Abstract/ Executive Summary:

ZTSS method gave an average yield of 8.1 t/ha which was about 0.5 ton higher than TP method. The higher yield in ZTSS method was mainly due to higher number of panicles/m² area. Crop under ZTSS method matured about 8 to 12 days earlier than TP method. Agro-economic analysis shows higher gross margin in ZTSS compared to TP method. The reason to have higher gross margin in ZTSS method was due to less cost in crop establishment method and higher yield compared to TP method. Because of lower cost of production and higher gross margin, ZTSS method may be an alternative option for Boro rice production in medium low and lowland ecosystem.

Keywords: Zero tillage, Surface seeding, BRRI dhan29, Farmers income

Location: Seven dispersed farmers’ fields of Gazipur district

Start Date: 01-07-2005

End Date: 30-06-2006

Program Area: Crop-Soil-Water Management

Commodity: Rice

Objectives:

To validate and transfer the technology for increasing farmers' income.

Methodology:

Zero tillage surface seeding (ZTSS) has been reported as an alternative crop establishment method to reduce the cost of production. For its validation, a trial was conducted in seven dispersed farmers’ fields of Gazipur district during Boro 2005-06. As a test material BRRI dhan29 was used. The experiment consisted of two methods of establishment: transplanting (TP) and zero tillage surface seeding (ZTSS). In ZTSS, sprouted seeds were sown in line using drum seeder onto the wet soil without any tillage just after recession of floodwater. In both the methods of planting, all amounts of P, K, S and Zn were applied at the time of final land preparation. Nitrogen was applied in three equal splits at 15, 40 and 55 days after transplanting in TP method while in ZTSS it was applied at 20, 40, 65 and 80 days after sowing. Other recommended management practices followed for this experiment.

Achievement/Findings:

In Kapasia, zero tillage surface seeding (ZTSS) using drum seeder gave 1.3 ton higher yield per hectare and matured 8 to 12 days earlier than TP method. ZTSS gave higher gross margin than TP.
