Abstract
The experiment was
conducted at Regional Agricultural Research Station, Rahmatpur, Barisal during
Rabi season of 2016-2017 and 2017-18 to find out the suitable combination of
inorganic fertilizers and organic fertilizers with proper planting technique in
a randomized complete block design. Nine treatments viz.T1=100%of RF+Bio-slurry
0 tha-1,T2= 100% of RF+Bio-slurry 5 tha-1,T3=100% of RF+Bio-slurry10tha-1,T4=50%
of RF+ Bio-slurry 0 tha-1,T5=50%of RF+Bio-slurry 5tha-1,T6=50% of
RF+Bio-slurry10tha-1,T7=75% of RF +Bio-slurry 0tha-1,T8=75% of RF+Bio-slurry
5tha-1,T9=75% of RF + Bio-slurry 10tha-1. The result revealed that when 100%
recommended dose of fertilizers was used with 10 tha-1 of bio-slurry gave
the highestyield (3.96 and 3.86 tha-1) which was statistically similar to the
yield (3.91 and 3.84tha-1) in T9 treatment where 10tha-1 of
bio-slurry was applied with 75% of recommended fertilizers.
Introduction
Wheat (Triticumaestivum)
belongs to the Graminae family, is one of the most important grain crops in
Bangladesh. In Bangladesh, per annum demand for wheat is 7.70 m tons, but its
production is only 1.15 m tons. The average production per hectare is only 3.38
tons (BBS, 2017). Hence, the production is much lower than demand. This lower
yield is due to a lack of balanced fertilizers as well as rice-based cropping
patterns. The soil fertility status of Bangladesh soil is degraded day by day.
More than 60% of our cultivated soil contains organic matter at a low level
(<1.7%) (FRG, 2012). According to an appraisal report of Bangladesh soil
resources, soils of about 6.10 m ha contain very low (less than 1%) organic
matter, 2.15 m ha contain low (1-2%) organic matter and the remaining 0.90 ha
contain more than 2 % organic matter (Mondal, 2000).Maintenance of soil
fertility is a must for long-term sustainable crop production.Soil fertility
and nutrient availability are closely connected to the soil's organic matter
content and its mineralization (Zech, 1996). Soil chemical, physical and
biological properties are also altered by manure applications and it seems
possible that long-term manure applications could change nutrient release
patterns significantly (Haynes and Naidu 1998). So, the application of organic
matter is essential for maintaining soil fertility. Wheat is sensitive to
nutrient stress. Bio-slurry is one of the organic sources which have been
obtained as a by-product of fermented biogas generated through the anaerobic decomposition
of various organic materials that can be used for crop production (Abubakar,
2012; Haque etal.,2015). Very little research work on bio-slurry was conducted
in the world. Therefore, the present study was undertaken to study the suitable
combination of inorganic and organic fertilizers for higher yield and economic
return.
