Abstract: Corrosion has adverse environmental consequences since it affects the manufacturing sector resulting in enormous economic loss. The corrosion characteristics and mechanism of mild in the solution of hydrochloric acid was studied. Extract of bush cane (Costus afer) was screened for physicochemical and phytochemical properties and utilized as corrosion inhibitor for mild steel, the process was optimized using Response Surface Methodology (RSM). The presence of OH, NH of alcohols, phenols, or substituents connected to aromatic rings, C=O for amides and ketones, C-N of aliphatic amines, and C=C of alkenes and nitriles were shown using Fourier Transform Infrared Spectroscopy (FTIR). The optimum condition was found by minimizing time, temperature, inhibitor concentration and corrosion rate while maximizing weight loss, and inhibitor efficiency. The results obtained revealed that the bush cane extract contain saponin, flavonoid, alkaloid and tannin, which suggests the potency of the extract as a good inhibitor as it contains a considerable amount of phytochemical with basic heteroatom. The statistical significance of the weight loss, corrosion rate and inhibitor efficiency were evaluated using the analysis of variance (ANOVA). it was observed that the regression was statistically significant at the F-value of 94.60, 25.87 and 4.72 respectively. P-value of > 0.0235, > 0.0001 and 0.0265 respectively. The optimum temperature, inhibitor concentration and contact time were found to be 27.9°C, 20.0% and 5 hours respectively at desirability value of 0.637. At this optimum condition, the weight loss was found to be 0.102%, corrosion rate was 1.583mg/cm2hr and inhibitor efficiency was 62.9%. From the results obtained in this experiment, It is concluded that the bushcane extract can be used as a corrosion inhibitor for the protection of mild steel.

Abstract: Potato is ranked third after rice and wheat in terms of consumption in the world, and first among root and tuber crops. However, the production is limited by several factors including low in soil fertility, lack of improved varieties, inappropriate spacing, and other poor agronomic management. The objective of the present study is to recognize the optimum rate of the blended NPSZnB and potassium fertilizers for profitable production of potato at Assosa area. The experiment was laid out in RCBD with arrangement of split plot in three replications. The main plot consisted of two potato varieties i.e. Belete and Gudane varieties. The subplot consisted of four levels of blended NPSZnB with potassium chloride rates, one recommended NPK (nitrogen, phosphorus and potassium) and unfertilized plot. The interaction effects of potato tuber size distribution and quality traits were not significantly (P>0.05) affected by different rates of NPSZnB with adjusted nitrogen, phosphorus and potassium chloride fertilizers and different potato varieties. Out of different potato varieties, Belete variety gave the highest yield as compared to Gudane variety. The highest total tuber yield and large sized tuber yield were obtained by the application of 200% NPSZnB (35.4N+70.6P2O5+15.2S+0.5B+4.4Zn) +138 kg K2O ha-1, with adjusted 184.6kg N+ 109.6kg P2O5 per ha therefore, we are tentatively recommended for beneficiaries at Assosa area.
