    Quality assessment of Amangwu-Edda stream and its tributaries for rice production under irrigation
    (Agricultural Society of Nigeria, 2020-08-30) Oti, N. N.; Mbe, J. O.
    Rice is one food that has solved the food security problems of many densely populated countries like China, India, Thailand and South Korea, etc. Inadequate and uneven distribution of rainfall and declining soil fertility are among the major challenges militating against increase in rice production in Sub-Sahara Africa. The problems associated with rainfall can be addressed through irrigation, a concept that involves the artificial application of water to the land in accordance with 'crop requirement', throughout the 'crop period', for fullf-ledged nourishment of the crop. Water sources to be used for rice production under irrigation in Amangwu-Edda, Afikpo-South Local Government Area (LGA) of Ebonyi State, South-East Nigeria were evaluated for their quality in terms of salt content. Laboratory results revealed that the water samples had mean pH value of 7.04 and Ca, Mg and Na values of 18.03mg/l, 6.07mg/l, and 1.75mg/l respectively. Similarly, mean SAR, K, SO CL, TDS, 4, -5 and EC were 0.913meq/l, 2.05mg/l, 202.5mg/l, 99.715mg/l, 1,001.4mg/l and 6.3x10 respectively. The result indicates that the water quality is safe for irrigated rice production. Similarly the mapping units studied are predominantly clay loamy, which is very ideal for irrigated rice production, but primary nutrients were generally low, and should be supplemented with organic or inorganic fertilizer.
