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.

精密滴灌系统对甜玉米品种物候和产量指标的影响

甜玉米是一种一年生植物，在种植和收获方面非常有用且经济。然而，在营养和水分缺乏的情况下，玉米林分会迅速受损。这项研究是在滴灌条件和不灌溉的对照地块下进行的，涉及七种不同的玉米杂交种。获得的结果表明，灌溉和非灌溉处理之间玉米穗轴干物质含量（DMC）没有变化。相关性分析表明，增加 DMC 会导致灌溉和非灌溉处理的甜玉米穗轴 (MC) 的水分含量降低。DMC和MC是影响灌溉处理产量指数的重要因素。Biplots 显示 Dessert R72 (10.82) 杂种对 Brix/Abbe 和 Brix/Atago Pal-1 的产量和影响最大，而 Messenger 杂种 (42. 96) 对 MC 的影响最大。还表明，DMC和MC是杂交种灌溉处理产量指数的重要因素。Noa (37.97) 和 Honey 杂交种 (27.88) 对非灌溉和灌溉处理的影响和性能最小。Messenger (11.25) 和 SF1379 混合型 (10.5) 在 Brix Abbe 和 Brix Pal 的灌溉处理和 Dessert R78 (13.5) 上的性能最高，Messenger 混合型 (11.8) 在 Brix/Abbe 和 Brix/Atago 上的性能最高Pal-1 在非灌溉治疗中。在所进行的灌溉处理中，就 Brix/Abbe 和 Brix/Atago Pal-1 的产量而言，Dessert R78 (13.5) 是表现最好的杂交种。88）对非灌溉和灌溉处理的影响和性能最小。Messenger (11.25) 和 SF1379 混合型 (10.5) 在 Brix Abbe 和 Brix Pal 的灌溉处理和 Dessert R78 (13.5) 上的性能最高，Messenger 混合型 (11.8) 在 Brix/Abbe 和 Brix/Atago 上的性能最高Pal-1 在非灌溉治疗中。在所进行的灌溉处理中，就 Brix/Abbe 和 Brix/Atago Pal-1 的产量而言，Dessert R78 (13.5) 是表现最好的杂交种。88）对非灌溉和灌溉处理的影响和性能最小。Messenger (11.25) 和 SF1379 混合型 (10.5) 在 Brix Abbe 和 Brix Pal 的灌溉处理和 Dessert R78 (13.5) 上的性能最高，Messenger 混合型 (11.8) 在 Brix/Abbe 和 Brix/Atago 上的性能最高Pal-1 在非灌溉治疗中。在所进行的灌溉处理中，就 Brix/Abbe 和 Brix/Atago Pal-1 的产量而言，Dessert R78 (13.5) 是表现最好的杂交种。
