Effect of Fertilizer and Agronomic Practices on the Growth of Boro Rice (cv. BRRI dhan58) in Haor Area

Abstract

The experiment was carried out at Sunamganj district during November 2014 to April 2015 to observe the fertilizer management and agronomic practices on the growth of boro rice (cv. BRRI dhan58) in haor area of Bangladesh. The experimental site was located under Sylhet basin (AEZ-21) having moderately acidic and medium with very low drainage facility and the soil was Loamy clays type. The experiment comprised two level of fertilizers viz. farmers’ practice based fertilizer (F1) and BARC recommended fertilizer dose (F2) and  three agronomic practices viz. farmers’ agronomic practice (P1), proper seedling age and proper spacing (P2), proper seedling age and proper spacing + Integrated Pest Management (IPM), (P3). The experiments were laid out in a 2x3 factorial fitted into a randomized complete block design (RCBD) with five farmers’ replications. Fertilizer significantly affected the growth parameter of boro rice (cv. BRRI dhan58). BARC recommended fertilizer treatment gave taller plant height (90.38 cm) at harvest than farmers’ practice based fertilizer treatment. The number of tillers (17.64) hill-1 at 90 DAT was significantly affected due to BARC recommended fertilizer than farmers’ practice based fertilizer. The growth parameter was not significantly affected due to agronomic practices. The non-significant effect of their interaction was recorded the highest plant height (90.50 cm) obtained from (F2P3) and number of tillers hill–1 increased up to 90 days after transplanting (DAT). From the results of the study it can be concluded that BARC recommended fertilizer dozes (F2) with proper seedling age and proper spacing + IPM (F2P3) gave the best growth performance of boro rice (cv. BRRI dhan58) in haor area.
