Reduced Irrigation Norm as a Sustainable Agrotechnical Measure in Sweet Corn Production

The study evaluated the effects of a reduced irrigation norm (50% of the full rate) on morphological characteristics of sweet corn grown under different genotypes and sowing dates. The experiment was conducted over two growing seasons using three hybrids and three irrigation treatments. Results showed that reduced irrigation did not significantly affect plant height, ear height, or number of leaves in more tolerant hybrids, while enabling substantial water savings. Statistical analysis confirmed significant effects of irrigation, genotype, sowing date, and their interactions on most traits. The findings demonstrate that reduced irrigation norms can be successfully applied as a sustainable agrotechnical measure in sweet corn production under conditions of limited water resources and climate change.
