Abstract

Nitrogen nutrient losses through ammonia volatilization, denitrification, surface runoff, and leaching are causing low nutrient use efficiency in agricultural systems. Split application of N and use of slow N nutrient releasing fertilizers are among the known methods of increasing nitrogen use efficiency (NUE). A field experiment was conducted in Fogera plain to study the productivity response of upland rice to different sources of N fertilizer, rates, and time of application on a total of five farmers’ fields during the main cropping seasons of 2018 and 2019. The experiment was conducted using a factorial arrangement of two sources of N fertilizer (conventional urea and slow-release urea), three N rates (69, 103.5, and 138 kg ha^-1), and three times of application (T1=1/3 at planting, 1/3 at tillering and 1/3 at panicle initiation (PI), T2 = 1/3 15 days after sowing (DAS), 1/3 at PI and 1/3 at heading, T3 = 1/3 15 DAS and 2/3 at PI laid out in a randomized complete block design with three replications. Phosphorous at rate of 46 kg P₂O₅ ha^-1 was commonly applied at planting for all treatments. The commonly grown NERIC-4 variety was used as a test crop. The results of the experiment showed that the rates and time of N applications were significantly affecting most of the parameters. However, the different N source fertilizers as well as all interactions of the treatments did not bring statistically significant difference in all the growth and yield parameters. Regarding the rates, the highest plant height (77.35 cm), fertile tillers number (70.37 m^-1 row), grain yield (5.3 t ha^-1) and straw yield (10.0 t ha^-1 were obtained when 138 N kg ha^-1 was applied. Concerning the N application timing, the highest plant height (77.5 cm), grain yield (4.9 t ha^-1), straw yield (9.6 t ha^-1) and thousand seeds weight (28.9 g) and the lowest number of infertile tillers (1.83 m^-1 row) were observed when 1/3 of N was applied 15 DAS and the remaining 2/3 at PI. Therefore, 138 kg ha^-1, of commercially available urea with an application time of 1/3; 15 DAS and 2/3 at PI can be used to produce NERICA-4 upland rice in Fogera plain and similar Agro-ecologies in Ethiopia.
