Purpose: is to enhance the nutrients use efficiency (NUE) along with the crop yield and quality by magnetic treatment (MT) of the groundnut (Arachis hypogaea L.) seeds pre-sowing as well as the MT of water used to dissolve the nitrogen (N) fertilizer under sandy soil field conditions. Methods: Treatments were distributed in a split-plots design in triplicates. The control CL has received the recommended dose RD of the N-fertilizer while other treatments received a 50% of the RD applied to the surface soil 30 days after planting. The main factor (F1) was the N-application rates 1000, 2000, and 3000 mg kg-1 of urea dissolved in the magnetically treated water (MTW) then sprayed on the soil in the liquid form five times after planting. The sub-factor (F2) was the time of MT (15, 30, and 45 min) of the groundnut seeds exposed to a magnetic field MF 1.4 T intensity before planting. Results: The soil available N, P, K, Fe, Mn, and Zn (mg kg-1) were increased significantly by 34.8%, 23.0%, 3.49%, 9.4%, 22.2%, and 23.2% respectively, at P ≤ 0.05 by the 45 min MT and 3000 mg kg-1 N relative to its corresponding control (CL). The MT has increased the seeds yield (kg ha-1) significantly in the order 45 min >30 min >15 min for the N-rates 1000, 2000, and 3000 mg kg-1. At the 45-min time, it was increased by 17.5, 15.3, and 14.8% for the N-rates, respectively. Conclusions: The 2000 mg kg-1 rate with MT of seeds for 15 min can be recommended for an acceptable nutrients use efficiency (NUE).

This research aimed to determine the best combination of nitrogen levels and hybrid varieties for optimal growth and yield of hybrid maize in Sundar bazar municipality, Lamjung, Nepal. The study used a two-factor factorial randomized complete block design (RCBD) with 12 treatments and three replications. The treatments consisted of two hybrid maize varieties (Rampur Hybrid-10 and CP 808) and six different levels of nitrogen doses (control, 120, 150, 180, 210, 240 kg N ha-1). The results showed that the growth and yield parameters of hybrid maize varieties increased significantly with increasing nitrogen levels. The application of nitrogen at the rate of 240 kg N ha-1 produced the highest plant height, number of leaves, leaf area index (LAI), stem diameter, thousand grain test weight, grain per cob, grain yield, biological yield, and harvest index. Even a small difference of 30 kg of nitrogen ha-1 within a treatment showed a significant effect on the growth and yield parameters of hybrid maize. The control plot had the least growth and yield parameters. The hybrid maize variety CP 808 outperformed Rampur Hybrid-10 in terms of grain yield, thousand grain test weight, cob length, grain per cob, and LAI. In conclusion, this study suggests that cultivating hybrid maize variety CP-808 with the use of nitrogen at the rate of 240 kg ha-1 is optimal for maize production in Sundar bazar, Lamjung, and mid-hills of Nepal with similar altitude and climatic conditions. This information can assist maize farmers in achieving high yields and increasing their income.

ABSTRACT

AUTOREGRESSIVE DISTRIBUTED LAG MODELING OF IMPACT OF CLIMATIC AND NON-CLIMATIC FACTORS INFLUENCING SORGHUM PRODUCTION IN ETHIOPIA

This study examined factors influencing sorghum output in Ethiopia using ARDL model over the period 1981 to 2020. The elasticity coefficient of crop growing period mean temperature showed negatively significant impact on sorghum production in the long-run, aligning with theory. Conversely, main-season rainfall had positively significant impact on sorghum output, contrasting with the theory. Among non-climatic variables, sorghum price and area under sorghum had affirmatively considerable contribution to sorghum production as expected in theory. In the short-run, mean temperature revealed negatively significant impact on sorghum production, supporting the theory. Conversely, the main season rainfall and area under sorghum production demonstrated positively significant impact on sorghum production. Furthermore, sorghum output is positively responsive to own price during the second lag differences, implying that any price incentive strategy should be released before the last year. Equally, sorghum output is positively responsive to fertilizers applied in the first lag, which implies that fertilizers applied on sorghum cultivation during first lag difference have positive contribution to sorghum output supply. In view of the results of the current study, it is strongly recommended that the government should come up with strategies and policies that help sorghum farmers to mitigate and adapt to climate change.

Sugarcane is a cash crop typically cultivated for sugar. Due to climate change, there is a rise in temperature, disruption in the rainfall patterns and cycle of seasons. Such changes in weather parameters affect sugarcane production as well as sugar recovery from the canes. The study was conducted in Uttar Pradesh, India using GIS (Geographic Information System) based models and statistical multiple linear regression from districtwise data on yield and climatic parameters over the study period (1986 to 2015). The GIS models reveal that climatic factors like rainfall, temperature and evapotranspiration changed significantly throughout the study.The multiple linear regression model shows that such changes in climatic parameters have a significant impact on the yield of sugarcane. Graphical analysis of yearly data on temperature and sugar recovery (%) showed that temperature affects the amount of sugar recovered from the canes. The study aims to illustrate the evidence of climate change and its impact on sugarcane production in Uttar Pradesh.

Purpose: This study investigated the suitability of nine common market food wastes in Nigeria for rearing Hermetia illucens. Methods: Substrate suitability was determined through periodic assessment for survival, and measurement of body length, width and weight of H. illucens on each substrate in the laboratory. Results: Survival of H. illucens larvae and pre-pupae on maize flour, cowpea flour, over-ripe banana peels, amaranth leaves, watermelon peels, and bread was comparable to the control substrate (chicken feed). In contrast, survival of larvae to pre-pupae on cabbage and pineapple flesh was significantly lower than on the control. Generally, larvae and adults reared on chicken feed had significantly higher body size and weight compared to those on pineapple flesh or pineapple peels. Conclusion: Due to their inherently high moisture, low protein and low carbohydrate contents, pineapple flesh and pineapple peels are the least suitable substrates for H. illucens survival and growth in the study.
