Efecto de tres abonos orgánicos en el rendimiento de Solanum tuberosum L. VAR. YUNGAY en Santiago de Chuco – La Libertad

The research work was carried out in the field of the former Agricultural Institute in Santiago de Chuco, La Libertad, to determine the effect of three organic fertilizers on the yield of Solanum tuberosum L. Var. Yungay. Full Random Block Design was used, with four treatments and four replicates; By means of the Analysis of Variance and the test of Tukey to 5%, it was possible to determine if there is a significant difference between treatments and blocks, being treatments T0 (Witness), T1 (20 t.ha-1 of sheep manure), T2 T.ha-1 of beef manure), T3 (20 t.ha-1 of guinea pig manure). The yields were T1, 46426.459 kg.ha-1; followed by T3, 38628.219 kg.ha-1; T2, with 37321.517 kg.ha-1, showing statistically significant differences between the T0 treatment, 26457.661 kg.ha- 1. It is concluded that the T1 treatment achieved higher performance compared to the other treatments under study; Number of tubers (22.80), tubers weight (1,525 kg), yield per additional and first category was 949,235, and 215,160 g.plant-1, including the number of stems 6.45, except plant height (81.469 cm), Diameter of stems 9,367 mm and yield of other category 176,000 g.planta-1 with T3 and the category Second 235.520 g.planta-1 with T2.
