“…It has also shown that the NE ® Model treatment showed the extra benefit if farmers really desire to grow the maize as advocated by NE ® model treatments. At present, the lack of technical knowledge in making inventory of various production technologies of crops is lacking in Nepal and farmers are getting less profitability from their farming (Amgain et al, 2022;Devkota et al, 2022). The adoption of NE ® -Maize model would help the farmers to compare their production and profitability levels in advance in making the cropping system more scientific and technological.…”

“…The green revolution in agriculture became successful only after the judicious management of seeds, fertilizers, irrigation water and their scientific management in most of developed world. The government of Nepal (GoN) has also planned to change its subsistence agriculture to commercial and more intensive enterprise-oriented systems for maintaining the balanced human nutrition in sustainable manner as indicated by UN-Sustainable Development Goals (Amgain et al, 2022, MoALD, 2021Timsina, et al, 2021). Manures and fertilizers being the vital components of the production in any agriculture system, GoN has also given special emphasis on it, but the unavailability of the Urea Nitrogen to be applied on demand at the time of transplanting to heading stages of main season rice, and the same problem with DAP and MOP fertilizers even in spring maize and wheat growing seasons have created the havoc situation, and it is looking a great threat of the country and the agricultural planners and concerned stakeholders are forced to think critically on its alternative remedies.…”

A multi-locational field trials were assessed to know the innovative fertilizer management tool (Nutrient Expert®) for improved nutrient management of Spring Maize in Rani Jamara Kulariya Irrigation Project Command Area (RJKIPCA) of Tikapur, Kailali during spring season of 2021. The layout and planting of Spring Maize for NE® - Hybrid Maize model for 42 farmers’ fields (Tikapur-18, Janaki-18 and Lamkichuha-6)], and Nutrient Omission Plot Technique (NOPT) maize trials for 21 farmers’ fields (Tikapur-9, Janaki-9 and Lamkichuha-3) were grown using baby trail/ diamond trials in Randomized Complete Block Design (RCBD) considering farmers as replications. Data recording, tabulation, and analysis and interpretation of the data was performed by using ANOVA through the use of R Stat-software. Data analysis was also done for the yield gap analysis using percentage change in yield of Spring Maize over the location due to changes in crop cultivars and NOPT. The experimental results highlighted that most of the soils in the project site were deficit in N followed by K, with the minimum yield loss due to omission of P. The treatment; farmers' fertilizer practices (FFP) with their own cultivar has shown more decreasing trend in Spring Maize yields and it was more prominently seen within the farmers growing hybrid maize than the open pollinated variety (OPV). With huge percentage of yield gaps in Spring Maize denoted that the soil of Janaki and Tikapur were found to be more prone to N and K nutrients deficient than the soils of Lamkichuha. NE®- Hybrid Maize model has fairly predicted the Spring Maize yields and predicted the sound results on profitability with assured actual attainable yield over the FFP. Therefore, NE-model for Spring Maize is suggested to adopt as a recommended decision support system (DSS) tool in the project command areas of RJKIPCA, Tikapur, Kailali.

“…It also enhances sustainable agricultural practices, which have longlasting beneficial impacts on the livelihood of farmers. CA can also enhance food access and nutrition by improving production and agricultural efficiency (Amgain et al, 2022). CA, when combined with value-chain interventions and postharvest management, can ensure the availability of nutritious food to the most vulnerable populations, thus decreasing malnutrition and improving human health.…”

Conservation agriculture (CA) aims to achieve productive and sustainable farming while preserving the natural resource base and environment. This article explores how CA aligns with Sustainable Development Goals (SDGs) of the United Nations and contributes to their achievement, particularly SDG 2: Zero Hunger, SDG 6: Clean Water and Sanitation, SDG 12: Responsible Consumption and Production, SDG 13: Climate Action, and SDG 15: Life on Land. CA has gained significant attention as a sustainable farming system on over 200 million hectares of global cropland, with an annual increase of 10 million hectares since 2008. The principles of minimum soil disturbance, diverse crop rotations and permanent soil cover help improve soil health, nutrients and water management, and contribute to biodiversity preservation. By encouraging sustainable agriculture and enhancing nutrition, SDG 2 seeks to end hunger. CA practices enhance soil health and nutrient availability, increasing crop productivity and reducing reliance on synthetic inputs like pesticides and fertilizers. The resilience of CA to climate change challenges further supports food production. For SDG 6, minimum tillage and soil cover components of CA help reduce soil erosion, resulting in cleaner water by preventing sedimentation in water bodies. Improved water management and conservation contribute to sustainable water use and sanitation. SDG 12 seeks responsible consumption and production patterns. CA promotes efficient resource use, reduces waste, and minimizes the negative environmental impact of agricultural inputs, leading to sustainable production systems with less reliance on external inputs. Regarding SDG 13, CA practices improve soil and water management, increase soil carbon absorption, and lower greenhouse gas emissions, all of which help agricultural systems become more resilient to climate change. Lastly, SDG 15 focuses on life on land preservation. CA's promotion of biodiversity through cover cropping and decreased chemical use provides habitats for organisms, supporting ecosystem services and sustainable land use. In conclusion, CA plays a significant role in achieving multiple SDGs by promoting sustainable agriculture, conserving resources, mitigating climate change, and preserving biodiversity. The adoption and expansion of CA practices are essential for a sustainable and resilient future

“…There are several factors that contribute to Nepal's low wheat yield, the most important of which is improper and insufficient fertilizer use (Amgain et al, 2022;Bhatta et al, 2020). This causes a large yield gap between a genetic potential of 11-13 t ha -1 (Senapati & Semenov, 2020) and actual yield at farmer's field.…”

“…It has been reported that the efficiency of N use in wheat in South Asia could be improved by using fertilizer N management strategies that are responsive to temporal variations in which N demands and supply vary from field to field (Amgain et al, 2022;Singh et al 2010). Improved synchrony of N supply with crop demand, N supply by soil, and applied N fertilizer at optimum dose appears to be more promising in wheat.…”

A field experiment was conducted at Tikapur, Kailali located in Sudur-Pashim Province of Nepal from November 2021 to April 2022 to determine the effects of site-specific nutrient management practice son the yield, economics and resource use efficiency of wheat (cv: Vijay). Six fertilizer treatments were laid-out in a Randomized Complete Block Design. The treatment includes nitrogen omitted plot (N0), blanket recommendation (BR), Nutrient Expert based-NPK (NE), Nutrient Expert based nitrogen recommendation and farmers fertilizer practice for other fertilizers (NE-N), leaf color chart-based nitrogen recommendation (LCC-N) and farmers fertilizer practice (FFP). NE produced the highest yield compared to BR and FFP. Grain yield between NE and LCC was similar (p>0.05). LCC-N produced the highest harvest index (0.46) and nitrogen use efficiency while they were the lowest in farmer-based practice. As with yield, NE produced higher gross revenue and benefit-cost ratio compared to farmers’ practice. Similarly, the maximum nitrogen uptake by grain and straw and soil residual N was observed in NE treated plot. These results suggested that NE based NPK management could increase yields, NUE and farm profit. However, similar benefits could also be achieved using either LCC based N management with 25 to 40% less N compared to NE. So, the fertilizer recommendation using NE-Wheat model in combination with LCC (if available to farmers) for N management could be suggested to the farmers for successful wheat cultivation.
