“…Nitrogen (N) is the most limiting nutrient essential for plant growth (Fageria & Baligar, 2005;Chen et al, 2014;Jahangir et al, 2022). The primary source of N used globally is urea, accounting for 48% of the 107 million tons (67.8 million tons) fertilizers used for crop production in 2017 (IFA, 2019).…”

“…In Bangladesh, the most important agronomic crops grown in oodplain soils are rice, potatoes, and maize, which require more N fertilizer with ine cient NUE, such as 33% for maize, 40-50% for potato, and 25-35% for rice (Jahangir et al, 2022). Residue management increases N uptake by crops and therefore, increases crop yields by in uencing several indices of NUE, for instance, NRI and SNMI (Kumar & Goh, 1999;Johnson & Raun, 2003;Huang et al, 2013;.…”

Nitrogen-use efficiency (NUE) of crops is critical for addressing global food security in response to climate change effects. The objective of our study was to evaluate the effects of N fertilization integrated with crop residue management to optimize NUE of crops. A replicated 2 x 4 split-plot experiment in randomized complete block design was conducted during the 2020–2022 on farmers’ fields at Bogura, Cumilla, and Mymensingh sites of Bangladesh. The main plots were two levels of crop residues (no residue, NR vs. 30% residue, CR) combined with sub-plots of four levels of N fertilizers (control, CL; farmers’ practice, FP; national recommended dose, RD, and 125% of RD, 125RD) on potato (Solanum tuberosum, L.), maize (Zea mays, L.), and rice (Oryza sativa, L.) systems. N fertilization when interacted with residue retention progressively increased crop yield. Residue alone contributed significantly to increase NUE of potato and maize by 9 and 6%, respectively. The NUE of rice increased significantly, while the NUE of maize decreased with N fertilization. The comparison of NUE models suggested that the nationally recommended N fertilization should be adjusted to 169, 152, 187, 92, and 112 kg/ha for potato, maize, Boro, Aus, and Aman rice, respectively. For potato and Aman rice, the SNMI showed better results, whereas for Boro, Aus, and maize, utilizing both NUE and SNMI provided maximum benefit from N management.

“…High rates of N fertilizer input, incorrect timing of application, and broadcast application of N fertilizer are the main causes of poor NUE in the rice growing context [1]. The above-mentioned causes facilitate gaseous N loss pathways such as volatilization and denitrification, which correspond to about 16-20% and 0.75-1.0% of applied N, respectively, at the research location [2,6]. The management and timing of N fertilizer application are crucial for enhancing NUE in rice.…”

Although urea placed deep reduces nitrogen (N) loss and increases rice yield, its use is not expanding due to the lack of effective application methods. A study was carried out to determine how different urea application techniques affected the yield and nitrogen use efficiency (NUE) of transplanted Aman rice (cv. BRRI dhan46). The experiment was set up in a RCBD design with seven treatments: T1 (deep placement of urea briquettes (DPUB) by hand), T2 (DPUB by battery-powered applicator), T3 (deep placement of prilled urea (PU) briquettes by BRRI applicator), T4 (DPUB by injector applicator), T5 (DPUB by push-type applicator), T6 (broadcast application of PU), T7 (zero-N), and three replications. Findings showed that the NH4+-N concentration in field water peaked on day 3 and then rapidly fell as time passed, while the NO3−-N concentration in the water and soil was minimal. T1 reported the highest grain yield, total N content and uptake, whereas T7 had the lowest values. On T1, the apparent N recovery reached its highest level (73.5%). The NUE varied from 13.26% in T3 to 29.38% in T1. Based on this finding, deep placement of urea briquette by hand is recommended for increasing the yield and NUE of T. Aman rice.
