Abstract:

A field experiment was conducted at Assosa Research center, western Ethiopia during 2017 in order to determine the optimum fertilizer rate and nutrient uptakes of Marekofana variety of Hot pepper. Experimental design of treatments was laid out in randomized complete block design (RCBD). The trial has eight levels of treatments (Recommended NP, three different blended rates for each NPSB and NPSBZn and unfertilized plot). Soil laboratory analysis indicated that the soil of the study site was acidic in reaction, clay loam in texture, low in total N, low in organic carbon. Low to very low in available P, S, Zn, B and medium CEC. The experimental result shows that highest total yield was obtained from 150% NPSBZn (2.44 t ha-1) as compared to other treatments; the nutrients concentration and nutrient uptake were significantly (P<0.05) varied among treatments and also nutrient use efficiency was improved by fertilizers application. The highest nitrogen (50.14), phosphorus (9.93) and sulfur (4.10) kg ha-1 pod uptake; higher agronomic efficiency (9.59 kg pod kg-1) and the highest apparent nutrient recovery for N (48.97%) and P (12.80%) were recorded with the application of 150 kg + 44 N kg ha-1 blended fertilizer rate. The uptake of N, P, K and S were significantly and very strongly correlated (P< 0.01) with total dry pod yield. Thus, based on the results of this experiment, the optimum fertilizer rates for Marekofana variety was obtained from the treatment of 150 kg + 44 N kg ha-1which recommended for the growers in the area.
