Abstract
A field experiment was conducted at National Agriculture Research Center (NARC), Islamabad, Pakistan to observe the
emergence and grain yield of maize crop under different fertilizer applications viz. 100-50-50, 150-75-75 and 200-100-100
kg ha-1 NPK and cattle manure 6000, 8000 and 10,000 kg ha-1 applied in the plots ploughed through tillage practices with
deep tillage, conventional tillage and zero-tillage. The non significant interaction between fertilizers and tillage methods as
well as between cattle manure and tillage methods each with three levels were found. It indicated that fertilizers and manures
should be studied independently using pair wise comparison. Pair wise comparisons indicated that the fertilizer at the rate of
150-75-75 kg ha-1 (NPK) was suitable for best germination rate and grain yield of maize. Similarly the deep tillage was
preferred over conventional and zero tillage, on the other hand, the highest level of manure (10000 kg ha-1) was
recommended for best germination rate and grain yield, where as 8000 kg ha-1 for grain weight and number of grains per cob.
