The experiment was conducted at the Agronomy Field Laboratory, Bangladesh Agricultural University during November 2016 to April 2017 to investigate the effect of nutrient management on the growth performance of some aromatic rice varieties in Boro season. The experiment was laid out in a randomized complete block design with three replications considering two factors viz. varieties and nutrient management. This experiment consisted of three varieties viz., BRRI dhan50, Basmati and BRRI dhan63, and seven nutrient managements viz., poultry manure 5 t ha-1, recommended dose of chemical fertilizers (i.e. 250, 126, 120, 100 and 10 kg N-P-K-S-Zn, respectively ha-1), 25% less than recommended dose of chemical fertilizer + poultry manure @ 2.5 t ha-1, 50% less than recommended dose of chemical fertilizer + poultry manure @ 5 t ha-1, vermicompost @ 10 t ha-1, 25% less than recommended dose of chemical fertilizer + vermicompost @ 5 t ha-1 and 50% less than recommended dose of chemical fertilizer + vermicompost @ 10 t ha-1. The results revealed that variety, nutrient management and their interaction exerted significant influence on growth characters of aromatic fine rice in Boro season. The highest plant height (55.14 cm, 66.14 cm) at 70 and 85 DAT, dry matter hill-1 (15.39 g) at 85 DAT and chlorophyll content (39.29) at 55 DAT was recorded from BRRI dhan63. While, Basmati produced the highest leaf area index (0.60) at 60 DAT and the highest number of total tillers hill-1 (11.52, 10.81, 9.619) was obtained from BRRI dhan50 at 55, 70, 85 DAT. In case of nutrient management practices, 25% less than recommended dose of chemical fertilizer + vermicompost 5 t ha-1 produced the highest plant height (45.22cm, 55.22cm, 65.67 cm) at 55, 70, 85 DAT, leaf area index (0.70) at 60 DAT and chlorophyll content (41.56) at 55 DAT, respectively. Again, from the interaction, it was observed that all the growth parameters were significantly influenced and increased with suitable variety along with proper nutrient management. Therefore, from this study, it can be decided that BRRI dhan63 fertilized along with 25% less than recommended dose of chemical fertilizer + vermicompost 5 t ha-1 might be the best possible combination for proper growth of plant.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
