Abstract

The impact of fertilizer of N and P on the yield of sesame in north-western Ethiopia was investigated. Field experiments were conducted in 2010 and 2011. Six levels of urea and six levels of di-ammonium phosphate were applied using a factorial completely randomized block design. Application of N and P increased the plant height, the number of capsules plant⁻¹, and the yield ha⁻¹. The number of days to flower decreased with increasing rates of nitrogen. The number of days to maturity was largest (91 days) at a rate of 23 kg N ha⁻¹. Applying 92 kg N ha⁻¹ resulted in a yield of 917.8 kg ha⁻¹ and a plant height of 104 cm. An application of 92 kg P ha⁻¹ with 36 kg N ha⁻¹ gave a yield of 908 kg ha⁻¹ and a plant height of 103.4 cm. The interaction between N and P significantly affected the number of days to flower, plant height, the number of capsules plant⁻¹, and yield ha⁻¹. Applying 128 kg N ha⁻¹ and 92 kg P ha⁻¹ gave the biggest yield (1043 kg ha⁻¹). However, application of 41 kg N ha⁻¹ and 46 kg P ha⁻¹ gave the largest marginal rate of return.
