“…Integration of organic manures with inorganic fertilizers also enhance soil properties particularly the soil organic carbon status and microbial community [22][23]. It has been also reported that combined application of manures and inorganic fertilizers increases cauliflower production in acid soil of Bangladesh [24]. Thus, economic and eco-friendly application of manures along with mineral fertilizers for profitable vegetable yield and sustainable soil health is a long-awaited demand both in agriculture and horticulture.…”

Aims: Under the intensive agriculture system, it is crucial to maintain the soil fertility for the sustainability of crop production. Therefore, the study was conducted in the experimental field of the Department of Soil Science of Bangabandhu Sheikh Mujibur Rahman Agricultural University (BSMRAU), Gazipur to investigate the effect of different manures in combination with synthetic inorganic fertilizers on growth, yield and yield contributing characters of BARI Mistimorich 1 (Capsicum annuum L.), a variety of sweet pepper. Nutrient content of capsicum and soil fertility status were also assessed. Materials and Methods: The field trial was established following a randomized complete block design (RCBD) having four replicates. Treatments of the field trial included T1= 100% recommended dose of chemical fertilizers (RDCF), T2= 10t/ha cowdung (CD) + IPNS based chemical fertilizers (CF), T3=10t/ha poultry manure (PM) + IPNS based chemical fertilizers (CF) and T4= 10t/ha vermicompost (VC) + IPNS based chemical fertilizers (CF). Results: Experimental results reveal that application of organic manures in combination with chemical fertilizers produced significantly higher plant height, plant weight, number of branches per plant, number of flowers per plant, number of fruits per plant, fruit weight, fruit length, fruit diameter, total yield and nutrient content and uptake in sweet pepper. Organic manures (CD, PM and VC) in combination with chemical fertilizers ensured higher nutrient uptake when compared with the sole application of inorganic fertilizers. Among the treatments, vermicompost treated plots gave the higher yield of sweet pepper and improved the post-harvest soil nutrient status. Conclusion: Vermicompost was found to be suitable as substitute of other organic manures for the production of capsicum.

“…Manures of both plant and animal sources bear great potential to enhance crop production and sustain soil fertility (Adekiya et al, 2019;Akhtar et al, 2019;Khanam et al, 2022;Salma et al, 2022). Manure reduces the use of inorganic fertilizers in crop production and lessens the detrimental effects on air, water, and soil environment (Iqbal et al, 2020).…”

A large amount of nitrogen (N) fertilizer is required for paddy cultivation, but nitrogen use efficiency (NUE) in paddy farming is low (20–40%). Much of the unutilized N potentially degrades the quality of soil, water, and air and disintegrates the functions of different ecosystems. It is a great challenge to increase NUE and sustain rice production to meet the food demand of the growing population. This review attempted to find out promising N management practices that might increase NUE while reducing the trade-off between rice production and environmental pollution. We collected and collated information on N management practices and associated barriers. A set of existing soil, crop, and fertilizer management strategies can be suggested for increasing NUE, which, however, might not be capable to halve N waste by 2030 as stated in the “Colombo Declaration” by the United Nations Environment Program. Therefore, more efficient N management tools are yet to be developed through research and extension. Awareness-raising campaign among farmers is a must against their misunderstanding that higher N fertilizer provides higher yields. The findings might help policymakers to formulate suitable policies regarding eco-friendly N management strategies for wetland paddy cultivation and ensure better utilization of costly N fertilizer.

“…Nutrient uptake from the soil was calculated by using the formula: Nutrient uptake = (% A x Y) ÷ 100 kg ha -1 [12] Where, %A = Nutrient content of plant dry matter in percent Y = Total dry matter production of plant (kg ha -1 ) Soil moisture used by the crop was determined by using the following formula:…”

A field experiment was accomplished from November 2018 to April 2019 at the site for agricultural research of Bangabandhu Sheikh Mujibur Rahman Agricultural University, Gazipur, Bangladesh to assess the effect of irrigation and nitrogen application on uptaking of primary nutrients by maize plant. A Randomized Complete Block Design (RCBD) with two factors and three replications was used to execute the experiment. Four irrigation treatments (I1, I2, I3 and I4: irrigation concerning 20%, 40%, 60% and 80% of soil available water, respectively) as factor A and three nitrogen doses [N1, N2 and N3: Nitrogen application at 75%, 100% and 125% of prescribed dose (PD) as per fertilizer recommendation guide (FRG)] as factor B was implemented. The crop responded significantly in uptaking N, P, K to different levels of irrigation and nitrogen. The uptake of N at its highest level (141.66 Kg ha-1) was observed in treatment I3N3 but the maximum uptake of P (49.17 Kg ha-1) and K (159.39 Kg ha-1) were found under the treatment I4N2. The addition of irrigation and nitrogenous fertilizer also enhanced the N (0.08%), P (8.75 ppm) and K (0.18 meq/ 100g) content of post-harvest soils. The maximum total consumptive use of water of the crop was found to be 446 mm in I4 treatment regardless N levels. Irrigation at 80% of soil available water using 100% N on prescribed dose (I4N2), appeared to be the most acceptable combination for optimal nutrient absorption by maize in the specified region.
