ABSTRACT

A field experiment was conducted during rabi, 2009 on sandyloam soils to study the effect of integrated weed management practices on yield, nutrient uptake and economics of baby corn. Results revealed that the cob green fodder yield, uptake of nutrients, net returns and benefit cost:ratio were highest with pre-emergence application of atrazine + one intercultivation at 30 DAS. The weedy check registered highest nitrogen, phosphorus and potassium uptake by weeds.
