Abstract/ Executive Summary:

This study was undertaken at GKF site, Kurigram and RDRS site, Pirganj, Thakurgaon to determine the soil test based fertilizer dose, BARC recommended fertilizer dose and farmers dose. t was evidenced that farmers used over and under dose of fertilizers for rice production. As a result they fail to obtain desired yield goal. Significant yield difference were found both in soil test based and BARC recommendation based fertilizer used over the farmers dose irrespective of varieties. About 1-2 t/ha higher grain yield was recorded in field situations when soil test based fertilizers were used for rice production. Such higher yields motivated the farmers to test their soil for management and are willing to pay for the test.

Keywords: Integrated crop management, Nutrient and Water Management, Water Use Efficiency, Boro Rice

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: Fertilizer

Objectives:

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

Methodology:

This study was undertaken in Boro season, 2001 – 2002 at GKF site, Kurigram and RDRS site, Pirganj, Thakurgaon to influence of soil test based fertilizer management on grain yield of rice and farmers’ reaction for sustainable crop production. Soil samples were collected from the selected farmers’ field of both the sites and analyses were completed by Soil Testing Kits. Two farmers were selected from Kuriram and two from Pirganj sites for this study. The rice varieties were BRRI dhan28 and BRRI dhan36. The experiments were laid out in a randomized complete block design (RCBD) with the following treatments and replicated three times within the selected farmers fields. The treatments were:T1 = Soil test based fertilizer dose, T2 = BARC recommended fertilizer dose and T3 = Farmers dose. The fertilizers were applied as per following the recommendation. The yield and yield contributing data of rice for each treatment was measured following the standard method. The collected data were analyzed statistically. The sowing dates of the experiments in GKF site were 1^st week to middle of December, 2001 and the transplanting dates within middle to last week of January, 2002. Whereas, the sowing dates of the experiments in RDRS site were 1^st week to middle of January, 2002 and transplanting within middle to last week of February, 2002 following the optimum sowing time of that locations. The soil texture of those sites is silty loam to sandy loam. I

Achievement/Findings:

Significant yield difference were found both in soil test based and BARC recommendation based fertilizer used over the farmers dose irrespective of varieties. About 1-2 t/ha higher grain yield was recorded in field situations when soil test based fertilizers were used for rice production. Such higher yields motivated the farmers to test their soil for management and are willing to pay for the test.
