biochar with different sources of organic manures on soil properties,
yield and yield attributing characteristics of cabbage (Brassica
oleracea var capitata) at Jamuniya-1, Nawalparasi from October 2015
to January 2016. The experiment was laid out in a Randomized
Complete Block Design (RCBD) with 10 treatments i.e Control, biochar
(100%), FYM (100 %), poultry manure (100%), vermicompost (100 %),
biofertilizer (100%), biochar (50%) +FYM (50%), biochar (50%) +
poultry manure (50 %), biochar (50%) + vermicompost (50 %), biochar
(50%) + biofertilizer (50 %) replicated 3 times. Biochar was prepared
from locally available rice husk under pyrolytic condition and applied
in field together with other organic amendments before 15 days of
transplanting. Analysis of primary nutrients of the organic manure
and biochar was done and rate of manure was fixed on the basis of their nutrient content. Biochar applied with organic manures
significantly increased soil pH (6.5) and SOM (2.24 %) than the plots
without biochar. The residual Nitrogen (0.143 %) was more in poultry
manure plots whereas soil P (118.70 kg/ha), soil K (385.7 kg/ha), was
more in biochar treated plots. This study showed that organic manure
applied with biochar increased soil properties as compared to control.
Biochar application provides an innovative method for handling excess
organic wastes to sequester carbon and to improve soil health and
plant productivity. | | Keywords : | | | Biochar, organic amendments, pyrolytic condition
