Abstract: The purpose of this study was to establish the optimum NPS rate based on calibrated phosphors for bread wheat productivity in Horo District. NPS fertilizer based on the critical levels of P and optimum N fertilizer determined for the district to determine the economically optimum levels of NPS. The treatments consist of 100% Pc from DAP and recommended N fertilizer and 100%, 75%, 50%, 25% Pc from NPS fertilizer with recommended N fertilizer and control (no fertilizer application) on a bread wheat, with seed rate of 150 kg ha-1. The two years (2020-2021) analysis of variance showed that biomass yield of bread wheat was highly significantly affected by the rate of NPS. The highest grain yield (5028.30 kg ha-1) and biomass yield (11455.4 kg ha-1) were obtained in response to the application of 100% of Pc from NPS + Rec. N, whereas the lowest grain yield (2882.2 kg ha-1) and biomass yield (8144.3 kg ha-1) were obtained from control treatment, respectively. The highest net benefit of 53247.4 Birr ha-1 was obtained from 100% of Pc from NPS with optimum N fertilizer application. Based on the findings of this study, 100% of Pc from NPS plus suggested nitrogen fertilizer was selected as the best and resulted in the highest yields of bread wheat production in Horo district, according to both agronomic data and partial budget analysis. Therefore, the technology's verification and demonstration for popularization should be continued.

Abstract: One of the plant species that is known for its therapeutic utilize is Salvia Rosmarinus. This experimental study aimed to evaluate anti-diabetic potential, anti-oxidant and antibacterial activities of the plant leave extracts with different solvent having varying polarity. Successive extractions were carried out with petroleum ether, ethyl acetate, and methanol and gave percentage yields of 3.00%, 10.01% and 14.04% respectively. The screening test for metabolites reveals the presence of Alkaloids, Anthraquinones, Phenols, Flavonoids, Steroids, Terpenoids, Saponins, Tannins and Glycosides from different crude extracts under some experimental protocols. The anti-diabetic ability of extract of Salvia Rosmarinus was evaluated by alpha-amylase inhibitory assay which implies that all methanol, ethyl acetate and petroleum ether extracts have greater potential to anti-diabetic activities at a higher concentration. The methanol extract showed the highest anti-diabetic activity from 59.77% to 94.19%, which is very close to the activity of acarbose a standard (72.36% to 95.71%). The ethyl acetate and petroleum ether extracts showed very slow at minimum concentration but rapidly increase their activity when their concentration becomes large from 11.31% to 94.11% and from 6.33% to 76.6% respectively. The total flavonoid concentrations of the petroleum ether, ethyl acetate, and methanol extracts were, respectively, 222.70, 152.1, and 113.71 mg QE/g. And the total phenolic content was 339, 182, and 28 mg GAE/g in methanol, ethyl acetate and petroleum ether extract respectively. Methanolic extract has higher total phenolic and flavonoid content and expected to the highest scavenging activity for free radicals. Lastly, an assessment was conducted on the antibacterial properties of the crude extracts. The highest minimum zone of inhibition was recorded in methanol crude extracts against a negative bacterium E. coli with minimum zone of inhibition 31 + 0.14 mm. Growth inhibition tests against bacteria showed a good result at a higher concentration in methanol and ethyl acetate extracts.
