“…Here, it is observed that reduced fertilizer dose found to produce a negative effect on plant height (Figure 3). Similar result on plant height due to fertilizer doses have also been reported in previous studies (Singh et al, 2006;Paul et al, 2020 andPaul et al, 2021), who noticed that higher fertilizer application significantly increased plant height. The other crop characters, yield components and yield were not significantly influenced by fertilizer management (Table 2).…”

The Study was carried out at the Salpoborian village under Sadr papilla of Mymensingh from February to June 2014 to assess the effect of crop establishment method and fertilizer management on the yield performance of Boro rice (var. BRRI dhan28) in T. Aman-Mustard-Boro rice cropping pattern. The experiment comprised three crop establishment methods viz. traditional puddled-transplanting (TPT), unpuddled-one pass in dry condition (UDC), unpuddled-zero tillage (UZT) and five levels of fertilizers viz., 100-60-40-60-10 N-P-K-S-Zn kg ha-1 at recommended (RD) dose (F1), N-K-S-Zn at RD plus 50% P (F2), N-P-S-Zn at RD plus 50% K (F3), P-K-S-Zn at RD plus 75% N as Guti urea (2.7 g/4 hills) (F4), P-K-S-Zn at RD plus 75% N as pilled urea (F5). The experiment was laid out in a split -plot design with 4 replications with crop establishment method in the main- plots and fertilizer management in the sub-plots. Grain yield was not significantly influenced by crop establishment method, fertilizer management and their interactions. However, numerically the maximum grain yield of 3.19 t ha−1 was found in both unpuddled-one pass in dry condition (UDC) and unpuddled-zero tillage (UZT) with 3.32 t ha−1 in P-K-S-Zn at RD plus 75% N as pilled urea (F5) and 3.47 t ha−1 in unpuddled-one pass in dry condition with P-K-S-Zn at RD plus 75% N as pilled urea and traditional puddled-transplanting with P-K-S-Zn at RD plus 75% N as pilled urea. Similar higher gross margin (Tk. 26629 and Tk. 27428) and benefit cost ratio (1.61 and 1.60) was also observed in UZT × F4 and UDC × F5, respectively. So, it can be concluded that unpuddled-zero tillage with P-K-S-Zn at RD plus 75% N as Guti urea (UZT × F4) and unpuddled-one pass in dry condition with P-K-S-Zn at RD plus 75% N as prilled urea (UDC × F5) is the beneficial technique for Boro rice (var. BRRI dhan28) cultivation in T. Aman-Mustard-Boro rice cropping pattern. Bangladesh Agron. J. 2023, 26(1): 32-39

Nitrogen and phosphorus are the essential nutrients involved in various physiological processes and affect the grain yield of rice. An experiment was conducted at the Agronomy Field Laboratory, Bangladesh Agricultural University, Mymensingh to find out how nitrogen and phosphorus affect the growth and productivity of fine aromatic rice. The experiment consisted of five levels of nitrogen viz. 0, 25, 50, 75 and 100 kg N ha-1 with four levels of phosphorus viz. 0, 15, 30, and 45 kg P2O5 ha-1. The experiment was set up using a randomized complete block design with three replications. According to the findings, the level of nitrogen, phosphorus and their interactions had a big impact on the yield and growth of aromatic rice. At harvest, the highest grain yield (4.15 t ha-1) was found in 75 kg N ha-1 which was identical with 100 kg N ha-1 while the lowest one was found in control (0 kg N ha-1). In case of phosphorus, 30 kg P2O5 ha-1 produced the maximum grain yield (3.73 t ha-1) compared to other treatments and the lowest grain yield was discovered in control (0 kg P2O5 ha-1). In interaction, the highest plant height (150 cm), number of effective tillers hill-1 (7.33), panicle length (24.00 cm), grains panicle-1 (136.9) and grain yield (4.37 t ha-1) were recorded in 75 kg N ha-1 × 45 kg P2O5 ha-1. Application of 75 kg N ha-1 along with 45 kg P2O5 ha-1 appears to be a promising combination for growing aromatic fine rice (cv. Binadhan-13).

“…Rice is consumed as the staple food in Bangladesh and has been given the highest priority in meeting the demands of its ever-increasing population (Paul et al, 2021a;Paul et al, 2021b). Based on the seasons of rice cultivation in Bangladesh, it has three distinct classes namely Aus, Aman and Boro, which are cultivated during the period of April to July, August to December and January to May, respectively.…”

“…Boro rice cultivation land increases 0.52% than previous year and covers an area of about 4.79 million hectares of land with a production of 19.89 million metric tons (BBS, 2021b) which accounts for 55 percent of the country's total rice production. In Bangladesh, more than 37 aromatic rice cultivars are grown but most of the scented rice varieties in Bangladesh are of traditional type, photoperiod sensitive, and cultivated during the Aman season but Boro season rice cultivar are few in number (Kabir et al, 2004;Paul et al, 2021b). Aromatic rice of Bangladesh is popular in Bangladesh and worldwide on account of its high export potential and its taste as well as better eating qualities (Rathiya et al, 2017;Teli et al, 2018).…”

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.
