The study was conducted to evaluate the effect of superabsorbent polymer (SAP) and irrigation interval on cowpea from June 15, 2021, to August 31, 2021, at Cagayan State University, Lallo Campus Sta. Maria, Lallo, Cagayan. The treatments considered in the experiment were: Factor A (SAP Levels): S1 –0.15g SAP/ 5 kg soil, S2 – 0.20g SAP/ 5 kg soil and S3 – 0.25g SAP/ 5 kg soil. Factor B (Irrigation Interval): T1 –Irrigation at Planting, T2 – 7 days irrigation interval, T3 – 14 days irrigation interval and T4 – 21 days irrigation interval. The pots were filled up with five kilograms of dried soil and the SAP was mixed thoroughly in the soil following its treatments. The study was laid out in Completely Randomized Design in Factorial with three replications. Wherein the parameters to be gathered are the following; plant height at 20, 40 and 60 days after planting, number of branches per plant, number of green pods per plant, the weight of green pods per plant, and pod length. The study result shows that the application of 80-100 kg SAP ha-1 at 14 days irrigation interval attained the tallest plants, the most number of pods per plant, more number of branches per plant, the heaviest pods per plant, and longest pods per plant. Using 80- 100 kg superabsorbent polymer per hectare and irrigation at 14 days interval is recommended for cowpea production.
