Yellow-MaizeThe present study aims to investigate the effect of wastewater on the yield of maize seeds based on randomized blocks with three frequencies. The treatments were applied in terms of two types of water qualities (Q1: well water and Q2: urban wastewater) as primary factors and three percent of water need (I1=100, I2=85, and I3=70) were regarded as secondary factors. The results showed that the treatment using purification wastewater, show more significant yield level than the other treatment approach using well water. The application of a 100-percent water need with wastewater in comparison to the treatment with an 85-percent water need culminated in a 4.6 percent increase in production yield, 6.7 percent boost in seed weight, 4.4 percent increase in the number of seeds in a row, as well as 3.5 percent boost in the number of seed rows. Also, the study indicated that the amount of consumable water in the treatment with 85-percent water need was reported to be 2420 square meters less than the control treatment. Furthermore, the water level of efficiency increased by 11 percent for the treatment with 85-percent water need. Hence, the study showed that irrigation with wastewater brings about a higher significant level of production for maize seeds rather than irrigation with well water.
