ABSTRACT

The objective of the study was to determine the effects of different irrigation levels on the yield and quality characteristics of two silage maize hybrids. Hybrids were established under four treatments of irrigation regimes with different tension in the soil: T1) 5–15 cbar, T2) 25–35 and 75–95 cbar, T3) 75–90 and 25–35 cbar, T4) 95–110 cbar. Variables were: dry matter yield (DMY), plant height, efficient irrigation water, efficient use of water resources, crude protein, neutral and acid detergent fibre (NDF and ADF, respectively), and net energy for lactation. Data analysis was undertaken with a randomized block design for each maize hybrid. Subsequently, quadratic equations were made to determine a maximum relative value. Irrigation treatment showed statistical differences between means in all agronomic hybrid characteristics. The best DMY in H-311 hybrid was noted in T1, T2, and T3 treatments (29 756–31 061 kg/ha), for 35p12 hybrid the best was T3 with 30 221 kg/ha. There were no differences in nutritional variables for H-311 hybrid. In 35p12 hybrid, T4 accumulated the highest concentrations of NDF and ADF with 61.83 and 44.19%, respectively. The maximum relative value of efficient use of water resource in H-311 was 4.9 kg/m³ with 518 mm, and 35p12 showed 5.6 kg/m³ with 405 mm. So, it is possible to achieve optimal yield and quality forage, reducing the depletion of aquifers.

摘要：本研究旨在确定不同灌溉水平对两个青贮玉米杂交种产量和品质特性的影响。在四种不同土壤张力的灌溉制度下建立杂交种：T1）5 ⁓ 15 cbar，T2）25 ⁓ 35和75 ⁓ 95 cbar，T3）75 ⁓ 90和25 ⁓ 35 cbar，T4） 95 ⁓ 110 cbar。变量包括：干物质产量（DMY）、株高、有效灌溉水、水资源的有效利用、粗蛋白质、中性和酸性洗涤纤维（分别为NDF和ADF）以及泌乳净能量。采用随机区组设计对每个玉米杂交种进行数据分析。随后，建立二次方程以确定最大相对值。不同灌溉处理的两个杂交玉米种所有农艺杂交性状的均值均存在统计差异。在T1、T2和T3处理（29 756 ⁓ 31 061 kg/ha）中，H-311杂交种的DMY最好，在35p12杂交种中，T3处理（30 221 kg/ha）的DMY最好。H-311杂交种的营养变量没有差异。在35p12杂交种中，T4积累的NDF和ADF浓度最高，分别为61.83%和44.19%。H-311水资源有效利用的最大相对值为4.9 kg/m3（518 mm），35p12为5.6 kg/m3 （405 mm）。因此，水分优化利用有可能实现最佳产量和优质饲料，减少含水层的损耗
