SOLIS ROSAS DIAZ, Luis Felipe; TEJADA SORALUZ, Jorge  e  JIMENEZ DAVALO, Jorge. Wheat yield cv. ‘centenario’ under different planting densities in a pressurized irrigation system. Rev. Inv. Cs. Agro. y Vet. [online]. 2021, vol.5, n.14, pp.204-217.  Epub 31-Ago-2021. ISSN 2664-0902.  https://doi.org/10.33996/revistaalfa.v5i14.111.

The experiment was carried out in the province and department of Ica, Perú (central coast) under a pressurized irrigation system, in the cultivation of wheat (Triticum aestivum ssp. Aestivum) cv. ‘Centennial’, in which there is a lot area under irrigation with high salinity water, wheat due to its resistance to high water salinity is a viable alternative. The Completely Random Block Design was used with factorial arrangement, with 9 treatments and 4 repetitions. Applying 2 factors, spacing between seeds (S) S0.5 cm, S1.0 cm and S2.0 cm and number of lines (L) L2, L4 and L6. For the comparison of means the Duncan test was used at 0.05 of significance. In all the variables in the analysis of variance, there was no significance obtained in the interaction between the factors S and L.In yield per ha-1 with the spacing between seeds at 1.0 cm and 2.0 cm (S1 and S2), 11513.89 and 11044.44 kg per ha-1 were obtained respectively and with four lines of wheat (L4) 12343.75 were obtained. The highest number of spikes per m-2 was obtained when sowing between seeds with 0.5 cm and 1.0 cm with 681.42 and 653.33 spikes per m-2. With 4 and 6 lines, 727.67 and 693.50 spikes per m-2 were obtained. To obtain the best yields and save seeds, factors S2 and L4 should be used. The highest number of spikes per m-2 was obtained with the factors S0.5, S1.0, L4 and L6.
