Abstract

Soil fertility decline results from different factors. Blanket fertilizer application throughout the country without considering soil types and agro-ecological are among the bottlenecks to obtain sustainable desired yield. This calls for site-specific nutrients managements and soil test based crop response fertilizer recommendations. The objective of the experiment was to determine economically optimum N, Phosphorus critical (Pc) and Phosphorus requirement factor for food barely production at Sinana district. A field trials were conducted from 2019 to 2021, using factorial combinations of four N levels (0, 23, 46 and 69 Kg/ha) and Six P levels (0, 10, 20, 30, 40, and 50 Kg/ha) chemical fertilizers, laid out in randomized complete block design with three replications. Food barely (Robera variety) with recommended seed rate of 125 kg/ha was used. Composite soil sample before plating and intensive soil samples after 21 days of sowing were taken from each plot and analyzed for selected physicochemical properties following standard laboratory procedures. Phosphorus critical level (Pc) determination was done using C'ate-Nelson diagram method. Agronomic data such as plant height; tiller, seed per spike, biomass, grain yield and thousand kernel weight were collected and subjected to two way factorial analysis of variance (ANOVA) using R software while the partial budget analysis was done using CIMMYT (1998). The results revealed that both N and combined NP fertilizer rates significantly influenced the agronomic parameters of food barely. Optimum nitrogen rate (46 N kg/ha), P critical concentration (20 ppm) and P requirement factor (4.60) for food barely production were determined at Sinana District. Therefore, uses of 46 N kg/ha fertilizer for food barely production at Sinana District and areas having similar soil conditions and agro-ecology is advisable. Farther verification of the result on farm land could be a pre request before disseminating the technology to the user.
