An assessment on iron ions concentration in Ruanda Majenje Improved Traditional Irrigation System was done in order to comprehend its accumulation, distribution and establish appropriate remedial measures for sustainable crop production. Specifically the study identified physical indicators associated with iron toxicity and assessed water constituents in irrigation canals. Crops grown in the field, the soil and water in the canals were examined for visible symptoms of iron ions toxicity. Data were collected using standard forms and analysed using Microsoft Excel program. Key findings indicate 55% of the rice plants had tiny brown spots (bronzing) and some had uniform brown color. The water in the diversion point, main conveyance system and drainage system had zero to relatively low mean Fe2+ constituent concentration (0 - 0.22mg/l). On the contrary the mean iron constitute in the secondary canal was high >3.30Mg/L. Moreover, the mean water pH was 6.8 with a highest value of 7.0 found in the drainage system. It was concluded that despite Fe2+ being a trace nutrient element for crop productivity, Ruanda Majenje Irrigation scheme has symptoms of Fe2+ toxicity. Also, that the mean pH for optimum crop productivity was slightly low (<7) but suitable for most crops (6.5 – 7). There is a need to explore possibilities of promoting water and soil quality for among others sustainable crop production in Ruanda Majenje Improved Traditional Irrigation Scheme. More research is needed to investigate other water constituents including Cl, SO4, Mn and CaCo3
