Abstract/ Executive Summary:

The experiment was conducted at the farmers’ fields of two villages namely Bahadurpur and Noagaonat Sadar upazilla and Daskin Sunamganj, respectively under Dekhar haor of Sunamganj district during the period from November, 2015 to May 2016 to find out the effect of variety and fertilizer on the, yield and yield contributing characters of premium quality rice in haor area. Two varieties (BRRI dhan50 and BRRI dhan63) and three fertilizer treatments (Farmers’ practice, FRG and Soil test based fertilizers) were included in the experiment. The experiment was laid out in a Factorial Randomized Complete Block Design (RCBD) with three dispersed replications. Tillers hill^-1 was significantly affected due to different varieties at 60, 75, 90 DAT (Days after Transplanting) and at harvest but significantly varied due to different fertilizers application at 30 and 60 DAT interaction at 45 and 60 DAT. The maximum grain and straw yield of 3.86 and 5.67 t ha^–1, respectively was produced from the BRRI dhan63. Though the grain yield was identical but lower yield in the STB and maximum in farmers’ practice due to higher fertilizer. practices

Start Date: 00-11-2015

End Date: 00-05-2016

Program Area: Crop-Soil-Water Management

Commodity: Rice

Objectives:

The trial was conducted to find out suitable variety and optimum fertilizer for premium rice of haor areas

Methodology:

The experiment was conducted at the farmers’ fields of two villages namely Bahadurpur and Noagaon at Sadar upazilla and Daskin at Sunamganjunder Dekhar haor of Sunamganj district during the period from November, 2015 to May 2016. Two varieties- V₁= BRRI dhan50 and V₂= BRRI dhan63 and three fertilizer treatments- F₁₌ Farmers’ practice (180-42-42 kg/ha of urea-TSP-MoP), F₂= Ferilizer Recommendatio Guide ’12 based on fertilizers dose (300-112-127-75-11 kg/ha of urea-TSP-MoP- CaS0₄-ZnS0₄) and F₃= Soil test based fertilizers (265-175-134-35-4 kg/ha of urea-TSP- MoP-CaS0₄-ZnS0₄) were included in the experiment. Soil texture, pH, organic matter, available P and S, Zn and exchangeable K, were determined following standard methods (Black, 1965; Jackson, 1962; Walkley and Black, 1935; Olsen et al., 1954 and Page et al., 1982). The experiment was laid out in a Factorial Randomized Complete Block Design (RCBD) with three dispersed replications. Seeds were sown in seedbed on 28 November 2015. Seedlings were transplanted on 4-5 January 2016 at 25 cm × 15 cm spacing. Urea was applied as top dressing in three equal splits at 15, 30 and 45 days after transplanting.. Two hand weddings were done where first weeding at 25 days after transplanting followed by second weeding after first weeding at 45 days. Standing water was maintained 2-3 cm in the field throughout the growing period. Five hills were tagged for counting the tillers and measuring the plant height. Harvesting was done on 21-22 April 2016. Ten hills were collected from each plot to record the yield contributing characters. The grain and straw yields were recorded. The data were analyzed and mean separation was done by DMRT.

Achievement/Findings:

The result of the experiment revealed that the higher grain and straw yield of 3.86 and 5.67 t ha^–1, respectively was produced from the BRRI dhan63. Soil test based fertilizer dose failed to show higher yield than farmer practice. Besides, FRG with high fertilizer dose did not increase yield in both the varieties. Though slightly higher grain yield was obtained from BRRI dhan63 with farmers practice with the use of affordable fertilizer dose and as such farmers of haor areas are very much
