Growth Characters of Boro Rice as Affected by Different Fertilizer Doses in Haor Area of Bangladesh

Abstract

The experiment was conducted at Bahadurpur village under the Laksmanshri union of Sadar upazila of Sunamganj district during November 2014 to May 2015 to evaluate the response of different varieties with the application of different fertilizers for obtaining optimum growth of boro rice in haor area of Bangladesh. Two varieties were selected from Bangladesh Rice Research Institute (BRRI)   viz. V1= BRRI dhan 29; V2= BRRI dhan 58 and three fertilizer treatments viz. F1= Farmers' practice-based fertilizer; F2= BARC recommendation guide based fertilizer; F3= Soil test based fertilizer were included in the experiment. The experiment was laid out in a randomized complete block design (RCBD) with five farmer field replications. BRRI dhan58 (92.17 cm) was significantly taller than BRRI dhan29 (89.60 cm). Plant height also significantly influenced due to application of fertilizer. The tallest plant (93.84 cm) was produced due to application of BARC recommendation guide based fertilizer. Number of tillers hill-1 was significantly affected in two rice varieties at 15, 30 Days after transplanting (DAT) and at harvest. Different fertilizer application significantly affected the number of tillers hill-1 of all Days after transplanting (DAT) and at harvest. At 75 Days after transplanting (DAT), the highest number of tillers hill-1 (18.72) was produced due to application of BARC recommendation guide based fertilizer. BARC recommendation guide based fertilizer treatment show best growth performance of boro rice in haor area.
