Abstract:
Effects of organic manures
on grain yield and yield components of
wheat (Triticum aestivum L.) cultivar
Minthar-03 were studied at (RARI)
Regional Agricultural Research Institute
Bahawalpur, Pakistan, during 2010-2011
seasons in chemistry division. The present
study have six treatments i.e. control,
NPK=150-120-60 kg/ha, control, NPK=
150-120-60 kg/acre, NPK+ poultry manure
50 kg /acre, NPK + press mud 500 kg/acre,
NPK + city compost 300 kg/acre, NPK +
humic acid 4 kg/acre. Combinations of NPK
+ PM 50 kg/ha having high plant height
(102.53) while number of (343) tillers/m2
was obtained high in combination with NPK
+ city compost 300 kg/ha which was at par
with combination (NPK + press mud 500
kg/acre) having plant height 100.90. spike
length, number of grains /spike, 1000 grains
weight, grain yield t/ha was 13.35 cm,
61.85, 40.60 grams and 3.14 t/ha
respectively obtained in treatment (NPK +
press mud 500 kg/acre). While minimum
amount of plant height (94.80), number of
tillers/m2 (223), spike length (10.35 cm),
number of grains/spike (43.43), 1000 grains
weight (35.33g), grain yield t/ha (38.41)
was found in control where no dose of
organic and inorganic fertilizer were
applied.
