Abstract:
Soil productivity one of the
essential factors which enhanced either
through adding the chemical fertilizer or by
incorporation of organic sources of nutrients
to the soil. Regardless by the used of
imbalanced fertilizer without the application
of organic manure and without seeking
knowledge of crops and fertility
classification of soil causes to much hazards
such as deterioration of soil structure, soil
and water pollution etc. Two years field
experiment was carried out to check the
impact of transitory nitrogen sources on the
nutrient concentration, uptake and
production of hybrid maize at the
Agronomic Research Area, University of
Agriculture Faisalabad, Pakistan, during the
year 2008-2009. Treatments included two
hybrids: H1 (Pioneer-30Y87) and H2
(Pioneer-31R88) with six nitrogen sources
each, which included at the rate of S0:
control (0) kg N ha-1, S1: chemical source
(urea) 250 kg N ha-1, S2: poultry manure
(PM) 9.6 t ha-1, S3: farm yard manure
(FYM) 17.8 t ha-1, S4: pressmud of
sugarcane (PMS) 8.5 t ha-1 and S5: compost
(C) 10.0 t ha-1. Finding concluded that
changing effect of nitrogen sources on both
maize hybrid was found to be non
significant during 2008-2009 while grain
yield was significant during both years.
Maximum nutrient concentration, uptake
and yield were observed with nitrogen
source S1: chemical source (urea) 250 kg
N ha-1 during 2008-2009 as compared to
other nitrogen sources and minimum was
found in control (0) kg N ha-1, respectively.
Interaction among hybrid and nitrogen
sources was found to be non significant.
