An investigation entitled “Evaluation of spring maize hybrids under irrigated conditions” was conducted at the instructional farm of Krishi Vigyan Kendra Langroya to check the yield potential of three maize hybrids during spring 2018 season. The experiment was laid out in randomized complete block design (RCBD) with six replications. All the crop management practices were followed as per the recommendations of Punjab Agricultural University, Ludhiana. The statistical analysis of data revealed that all the hybrids were non-significantly different with respect to maize cob weight, cob weight, grain: cob ratio, cob length, cob girth at base, middle and top. Numerically, P1844 resulted in highest value of maize cob weight, cob weight, grain: cob ratio, cob length, cob girth at base, middle and top in comparison to PMH 10 and DKC 9108. Maize hybrid P 1844 had significantly higher number of rows per cob (17.50) as compared to PMH 10 (14.67) but statistically at par with DKC 9108 (16.33). Other yield attributes viz., shelling percentage, 100-seed weight were found to be non-significantly different. The significantly higher grain yield was recorded in P 1844 hybrid (85.46 q/ha) followed by DKC 9108 (69.55 q/ha) and PMH 10 (68.71 q/ha).
