Time of Harvest as the Determinant of Dry Matter Productivity and Chemical Composition of Field Pea (Pisum sativum) and Oat (Avena sativa) and their Mixture in the Abandoned Lands of Subtropical Terai Nepal

The grass-legume mixture formulation is an important criterion to improve biomass availability with improved balance of the nutritive components. objective ofthis reseach was determine yield and forage quality traits (green fodder yield, dry matter yield) chemical composition (protein, fibre mineral contents) field pea (Pisum sativum) oat (Avena sativa) their mixtures under subtropical conditions. experiment performed over 4 months (December 2018 March 2019) at Agriculture Forestry University Livestock Farm, Rampur, Chitwan, Nepal, using four different treatment rates crops. Treatments were; treatment-1 - 100% Pea+0% Oat, treatment-2 75% Pea+25% treatment-3 -50% Pea+50% Oat treatment-4 25% Pea+75% Oat) samples were collected in three cutting stages (the jointing stage oat, scabbard milk dough oat). plant height affected by growing days while tillers branches peas respectively both time harvest seed proportions. According results, it suggested that highest productivity observed mix 3rd harvest, followed harvest. As well as, within intercrops, best protein obtained a 50% (16.73%) 1st oat-pea intercropping. Besides, + should be harvested milk-dough for better content increase value forage.
