Abstract: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, N… Show more
“…Achieving optimal utilisation of nitrogen fertiliser can be accomplished through the modification of cultivation techniques, with a primary focus on cultivating varieties that possess superior nitrogen absorption efficiency. This approach enables the attainment of high crop yields while minimising input requirements [24][25][26]. The utilisation of fertilisers has been found to have detrimental effects on local surface water resources, resulting in pollution.…”

The escalating severity of the water problem poses a potential threat to the prospects of sustainable development in the future. The grey water footprint is an indicator of the need for fresh water to mix and dilute pollutants and maintain air quality according to water quality standards. The evaluation of the grey water footprint (GWF) serves as a valuable measure in the mitigation and management of water contamination. The main objective of this study is to determine the grey water footprint associated with crop production along the Kampar Watershed and develop strategies to mitigate pollution levels. The grey water footprint is calculated using a water footprint assessment method. The finding show that the grey water footprint of rice farming (17.01 m3/ton) is larger than the maize (9.51 m3/ton), this indicate that necessary to improve water management on rice and maize agriculture. The water footprint performance scores of rice and corn plants are both in the poor category with scores of 11.93 and 45 respectively. To improve grey water performance and reduce air pollution, it can be done by using fertilizer according to plant needs, replacing inorganic fertilizer with organic fertilizer, implementing practices conventional tillage and maintain soil moisture.
