This research was conducted at the IVITA Mantaro station of the National University of San Marcos, in the Junín Region. The objectives were: (a) To determine the effect of pea cultivation as a temporary crop in the establishment of an associated pasture (Gramineae with legumes) in the Mantaro valley; (b) To determine the diversity and effect of weeds in the establishment of the associated pasture in the Mantaro valley; and (c) To determine the sustainability of the incorporation of the pea as a temporary crop, during the establishment of the associated pasture, seeded in the Mantaro valley. The treatments were: T1 (establishment of the associated pasture, with manual weeding and without pea), T2 (establishment of the associated pasture, without weeding, nor pea) and T3 (establishment of the associated pasture, without manual weeding, seeded with pea). Treatments were arranged in a randomized complete block design with three replicates. In each plot the associated pasture (Gramineae with legumes) was seeded, in amounts equivalent to 10 kg ha-1 of Lolium multiflorum, Var. “Tama”, 10 kg ha-1 of Lolium x boucheanum Var. “Belinda”, 5 kg ha-1 of Medicago sativa Var. “SW8210” and 3 kg ha-1 of Trifolium pratense Var. “Quiñequeli” In treatment T3, prior to planting of the associated pasture, the equivalent of 50 kg ha-1 of pea Var. “INIA103Remate” was broadcasted. The botanical composition of the pastures was evaluated at 120 days after sowing. It was found that weed population in T2, which was 21.63% by the absence of manual weeding, was reduced to 13.85% in T3, which indicates that the pea competed advantageously with the weeds. When the economic analysis was carried out, it was determined that the net profit from the sale of peas at 120 days, covers the costs of establishing the associated pasture. Weeds of the Asteraceae and Poaceae families recorded the highest number and richness of species, while the Brassicaceae family recorded the highest abundance during the establishment of the associated pasture in the Mantaro Valley. The most important species, according to the Importance Value Index were: Brassica rapa subsp. campestris, Avena sativa and Medicago polymorpha. It is concluded that the incorporation of pea as a temporary crop during the establishment of an associated pasture is a sustainable practice for the Mantaro valley.
