This study was conducted in Campus II, property of the Private University “Antenor Orrego” (Trujillo, Peru), to determine the effect on grain yield of two yellow endosperm single hybrids corn (H1: INIA 605 and H2: DK 7508), at two planting densities (D1: 88867 plant/ha and D2: 66665 plant/ha). Density 1 was achieved by placing hills at 15cm and 30cm, with 1 and 2 plants respectively; whereas for Density 2 hills were at 20cm and 40cm, with 1 and 2 plants each. Rows were at 75 cm apart from each other. The experimental layout was a factorial in a Split Plot design with four repetitions, with Hybrids in the main plots and Hills distances in the subplots. Results indicated that, on average, the highest grain yield was obtained at Density 1 (88867 plants/ha) with a superiority of 1.16 t/ha over Density 2 (66665 plants/ha). Hybrid DK7508 had the best grain yield with 13.36 t/ha on average. The treatment combination that reached the highest grain yield was H2G3 (DK 7508 x 30 cm – 2 plants/hill, 88867 plants/ha) with 14.56 t/ha. With respect to hill distances within the same plant density, there was no statistical difference in grain yield between 15 cm-hills (1 plant/hill) and 30 cm-hills (2 plants/hill). Same results were obtained between 20 cm-hill (1 plants/hill) and 40 cm-hill (2 plants/hill). This mean that in manual planting farmers can saved a valuable effort by planting 2 plants per hill, rather than 1 plant per hill, since the latter would mean double the amount of hills. Plant density did not affected ear length, ear perimeter, grain width, grain thick, and grain length, the same as with flowering and plant height. On the other hand, basal and medium stalk diameter and ear height were affected by different plant densities.
