Triticale (x Triticosecale Wittmack): organic bioestimulants and nitrogen fertilization on forage yield components in small campaign-Mantaro Valley. Scientia Agropecuaria [online]. 2019, vol.10, n.4, pp.469-477. ISSN 2077-9917.  http://dx.doi.org/10.17268/sci.agropecu.2019.04.03.

The fractional application efficiency of nitrogen fertilizer and organic biostimulants is affected by the time of supply in the crop. The objective of the study was to determine the effect of the fractionated application of nitrogen and organic biostimulants in different phenological stages of triticale (xTriticosecale Wittmack), and its relationship with forage yield and its components under small campaign conditions and low irrigated. The trial was carried out in fallow fields of 2018, lot 2, EEA El Mantaro-UNCP, El Mantaro-Jauja. The treatments consisted of the application of two and three fractions, of nitrogen, dose 150 kg ha-1 and biostimulants, 3 l ha-1, during two and three early phenological stages: tillering, expanded flag leaf and boot. The experimental design was randomized complete blocks with three repetitions. The fractionation in two, of the nitrogenous fertilization (75 kg ha-1) and of the Stym25 biostimulant (1.5 l ha-1) applied in two stages, tillering (five tillers) and stem elongation (expanded flag sheet), were associated with higher production of aerial biomass (forage) and greater establishment of stems (tillers) per unit area, implanting 47.89 t ha-1 of forage and 600 stems m-2
