Abstract/ Executive Summary:

This study was undertaken at GKF site, Kurigram and RDRS site, Pirganj, Thakurgaon to know initial status of soil fertility and land suitability for the crops to be grown. The result reveals that the soils at GKF site, Kurigram are mostly acidic in nature and highly degraded. It requires liming at 2-4 t/ha and addition of organic materials for profitable crop production. Most of the soils were with low to very low N, P, K, S Zn, and Ca status indicating that proper nutrient management should be followed for higher yield goal. Similarly, soils at RDRS site, Pirganj, Thakurgaon were acidic in nature, many of which would require liming at 2-4 t/ha. Most of the soils were with low to very low N, K, S, and Zn status indicating that adequate fertilizers should be added for higher yield goal. Phosphorus status of the soil varied considerably from very low to high. N rate in some cases may be required to reduce. Fertilizer needs for growing HYV T. Aman rice at RDRS site, Pirganj, Thakurgaon were stated that estimated N rates are high, which may be needed to reduce considerably based on variety and other management practices concern.

Keywords: Integrated crop management, Nutrient and Water Management, Fertilizer Management, Cropping Pattern

Location: GKF site, Kurigram and RDRS site, Pirganj, Thakurgaon

Start Date: 01-07-2001

End Date: 30-06-2002

Program Area: Crop-Soil-Water Management

Commodity: Soil fertility

Objectives:

To ensure balance fertilizer management for a crop;
To improved crop yield; and
To maintained and/or improve soil productivity.

Methodology:

This study was undertaken in Rabi and Boro seasons, 2001 – 2002 at GKF site, Kurigram and RDRS site, Pirganj, Thakurgaon to know initial status of soil fertility and land suitability for the crops to be grown. Soil samples were collected from the selected farmers’ field of both the sites and analysis were completed at Soil Resources Development Institute (SRDI), Rajshahi.

Achievement/Findings:

Soils at GKF site, Kurigram are mostly acidic in nature and highly degraded. It requires liming at 2-4 t/ha and addition of organic materials for profitable crop production. Most of the soils are with low to very low N, P, K, S Zn, and Ca status indicating that proper nutrient management should be followed for higher yield goal. Similarly, soils at RDRS site, Pirganj, Thakurgaon are acidic in nature, many of which would require liming at 2-4 t/ha. Most of the soils are with low to very low N, K, S, and Zn status indicating that adequate fertilizers should be added for higher yield goal. Phosphorus status of the soil varied considerably from very low to high. N rate in some cases may be required to reduce. So, necessary precautions will be needed while topdressing urea. Fertilizer needs for growing HYV T. Aman rice at RDRS site, Pirganj, Thakurgaon stated that estimated N rates are high, which may be needed to reduce considerably based on variety and other management practices concern.
