A field experiment was conducted at Central Research
Field of Bangladesh Agricultural Research Institute,
Joydebpur, Gazipur, Bangladesh during rabi season of
2008-2009, 2009-2010 and 2010-2011 to study the
effect of tillage and Integrated Plant Nutrient
System (IPNS) on soil physical properties and yield
of hybrid maize. Eighteen treatment combinations
comprising 3 tillage practices which are T0:
minimum tillage, T1: tillage up to 10-12
cm and T2: tillage up to 20-25 cm depth
and 6 levels of fertilizer i.e. F1:
control, F2: 5 ton cowdung + (R-M=Recommended
dose minus nutrient content in organic manure at 40%
mineralization.)
(R-M) ha-1, F3: 10 ton cowdung
+ *(R-M) ha-1, F4: 2.5 ton
poultry manure + *(R-M) ha-1, F5:
5 ton poultry manure + *(R-M) ha-1 and F6:
recommended dose (RD): N255, P55,
K100, S40 and B1
kg ha-1
was tested in a split- plot design with three
replications. Bulk density, particle density,
porosity and field capacity were slightly affected
by tillage and IPNS which were non-significant.
Yield and yield contributing characters of hybrid
maize were significantly influenced by both the
treatments singly. The F3 {10
ton cowdung + *(R-M) ha-1}
treatment gave the highest grain yield 9.72 ton ha-1
followed by F5 {5
ton poultry manure + *(R-M) ha-1}
treatment (9.40 ton ha-1). Interaction effect of
tillage and fertilizer on yield and yield
contributing characters was non-significant.
