Abstract
Esta investigacion se llevo a cabo en el Centro de Investigaciones IVITA de la Universidad Nacional Mayor de San Marcos en el departamento de Junin, Peru. El objetivo principal fue determinar el efecto de plantas de arveja ( Pisum sativum ), sembradas al voleo para establecer un cultivo temporal, sobre la abundancia y composicion botanica de especies de malezas durante el establecimiento de una mezcla de pastos de gramineas y leguminosas en el Valle del Mantaro . Se evaluaron los siguientes tratamientos: T1, pasto mixto con deshierbe manual, sin arveja. T2, pasto mixto sin deshierbe y guisante de olor. T3, pasto mixto con guisante de olor y sin deshierbe. Se utilizo un diseno de bloques completamente aleatorizados con tres repeticiones para el analisis estadistico del experimento. Todas las parcelas fueron sembradas con, 10 kg ha-1 de Lolium multiflorum Justicia. 'Tama', 10 kg / ha de Lolium boucheanum K. 'Belinda', 5 kg / ha de Medicago sativa L. 'SW8210' y 3 kg / ha de Trifolium pratense L. 'Quinequeli'. 50 kg / ha-1 adicionales de Pisum sativum L. 'INIA 103 Remate' se difundieron primero en el tratamiento T3. La composicion botanica de las malezas se evaluo en los tratamientos T2 y T3. Las familias de malezas Asteraceae y Poaceae registraron mayor numero de especies mientras que la familia Brassicaceae registro la mayor abundancia, durante el establecimiento de pasturas en el Valle del Mantaro. Las especies mas importantes segun el Indice de Valor de Importancia (IVI) fueron: Brassica rapa subsp. campestris, Avena sativa y Medicago polymorpha .
Highlights
In the Mantaro valley, 60 kg/ha of seed is used for sowing garden pea, and its cultivation involves cultural practices
As early varieties of garden pea with erect growth and high demand as vegetables are available, some studies showed the possibility of planting them as a temporary crop during pasture establishment (Ordóñez et al, 1999; Ordóñez and Bojórquez, 2001)
Forage mixtures planted in the Mantaro valley are characterized by a tolerance to competition produced by weeds and by having a subsequent recovery in vigour and dry matter production (Ordóñez and Bojórquez, 2011)
Summary
In the Mantaro valley, 60 kg/ha of seed is used for sowing garden pea, and its cultivation involves cultural practices (sowing, weeding, tillage, hilling, pest management and control, etc.). As early varieties of garden pea with erect growth and high demand as vegetables are available, some studies showed the possibility of planting them as a temporary crop during pasture establishment (Ordóñez et al, 1999; Ordóñez and Bojórquez, 2001). Temporary crops have certain benefits such as: rapid growth and cover of the soil when forage grasses and legumes are in the early stages of development, weeds are supressed, soil erosion by water is reduced, fodder production is ensured and competition is minimized. Forage mixtures planted in the Mantaro valley are characterized by a tolerance to competition produced by weeds and by having a subsequent recovery in vigour and dry matter production (Ordóñez and Bojórquez, 2011). In the central highlands there is no research on weed diversity nor on their effect on pasture establishment (Rojas et al, 2011, 2012, 2013a, 2014a)
