Sweet maize is an annual plant that is extremely useful and economical for planting and harvesting. However, maize stands are damaged quickly in the case of nutrient and water deficiency. This research was carried out under dripping irrigation conditions and control plots without irrigation, involving seven different maize hybrids. The obtained results showed no existing variation in the dry matter content of cob (DMC) between the irrigated and non-irrigated treatments. Correlation analysis showed that increasing DMC causes decreasing moisture content of cob (MC) of sweet maize with irrigated and non-irrigated treatments. DMC and MC are important factors in the yield index on irrigation treatments. Biplots showed that the Dessert R72 (10.82) hybrid had maximum yield and effect on Brix/Abbe and Brix/Atago Pal-1, while the Messenger hybrids (42.96) had maximum effect on MC. It was also shown that DMC and MC are important factors in the yield index on irrigation treatments on hybrids. The Noa (37.97) and Honey hybrids (27.88) had minimum effect and performance on non-irrigation and irrigation treatments. The Messenger (11.25) and SF1379 hybrids (10.5) had a maximum performance on Brix Abbe and Brix Pal in the irrigation treatment and Dessert R78 (13.5), the Messenger hybrid (11.8) had a maximum performance on Brix/Abbe and Brix/Atago Pal-1 in non-irrigation treatment. The Dessert R78 (13.5) is the best-performing hybrid in terms of the yield of Brix/Abbe and Brix/Atago Pal-1 in the performed irrigation treatments.
