Abstract
A field experiment was conducted at Forage Research Farm, Department of Plant Breeding and Genetics, PAU, Ludhiana and Regional Research Station, Gurdaspur during the Kharif season of 2020 in fodder maize to evaluate the impact of different weed management treatments on the relationship amongst weed parameters, fodder maize crop characters and green fodder yield. Green fodder yield of maize showed a significant positive correlation with weed control efficiency, maize plant dry weight and plant height. On the contrary, these parameters were negatively correlated with the weed density and biomass at the knee high stage of the crop. The average of the two locations indicated that a unit increase in weed density and biomass reduced maize fodder yield by 0.0655 and 0.083 t/ha, respectively. Similarly, the increase in the maize fodder yield due to a unit increase in weed control efficiency was estimated at 0.166 t/ha.
