Description
Summary:A field experiment was conducted to study growth and yield response of maize to organic and inorganic sources of N at the Agronomic Research Area, University of Agriculture, Faisalabad. Two maize varieties namely Composite-78 and Composite-79 were fertilized with farmyard manure @ 15000 kg per ha and urea @ 260 kg per ha on a sandy clay loamy soil. Composite varieties differed significantly in plant height, numbers of cobs per plant, number of grains per cobs, 1000-grains weight, grains yield and harvest index. Composite-78 performed best with respect to all growth and yield parameters expect numbers of plants per unit area and number of cob bearing plants. Combined use of urea and farmyard manure performed best than their sole application in respect of grain yield, which was 6.13 tons per ha.
