Abstract
A field experiment was carried out to determine the effect of NPK and organic manures on growth and yield of two
maize hybrids. Experiment comprised of two factors (H) hybrids (H1: FHY-421 and H2: FHY-434) and (F) four
fertilizer types, viz. F1: inorganic fertilizer (control) NPK @ 120:60:50 kg NPK ha-1, F2: poultry manure @ 15 t ha-1,
F3: FYM @ 20 t ha-1 and F4: bio-fertilizer @ 30 g kg-1 seed. So, the treatments comprised of T1 (F1+H1), T2 (F1+H2),
T3 (F2+H1), T4 (F2+H2), T5 (F3+H1), T6 (F3+H2), T7 (F4+H1), and T8 (F4+H2). As the experiment was laid out in
randomized complete block design with factorial arrangement, it was observed that although FHY-434 with
inorganic fertilizer NPK @ 120:60:50 kg NPK ha-1 i.e T2 (F1+H2) produced maximum plant height (212.30 cm),
number of grains cob-1 (606.60), 1000-grain weight (310.90 g ), grain yield (8.44 t ha-1 ) and net profit (Rs. 85803
ha-1), followed by FHY-434 with poultry manure @ 15 t ha-1 i.e T4 (F2+H2) in the same parameters, yet T4 (F2+H2)
with net profit Rs. 83764 ha-1, is being advocated for organic cultivation for long term and sustainable production
keeping in WTO scenario, as it produced grain yield 8.91 t ha-1.
