| Abstract Interference from weeds directly affects the productivity and the quality of elephant grass (Pennisetum purpureum) fodder. The difficulty in controlling weed species is one of the primary limitations to the production and use of elephant grass as forage in dairy farming and for biomass production in energy generation. The objective of this study was to determine the different periods in which yellow nutsedge (Cyperus esculentus) interfered with elephant grass forage yield. Two field experiments were conducted using a randomized complete block design with four replicates in Valenga, Rio de Janeiro State, Brazil. Elephant grass and weeds were maintained together for increasing periods of time: 0, 14, 28, 42, 56 and 70 days after planting (DAP)... |
