Abstract:
An experiment was conducted in the Farm of Sher-e-Bangla Agricultural University,
Dhaka, Bangladesh during the period from February to July 2009 to study the
influence of crop residues, press mud and tannery waste on the growth and yield of
aus rice. The experiment consisted of 10 treatments such as- T
1
: No chemical
fertilizer, no organic amendment (control); T
2: 100% recommended N, P. K and S
(100 kg N, 60 kg P205, 40 kg K
2
0 and 25 kg S/ha); T
3
: Decomposed crop residues
(rice straw) without nutrient enrichment; 14
: Decomposed crop residues (rice straw)
with nutrient enrichment; T5
: Decomposed tannery waste without nutrient enrichment;
T6
: Decomposed tannery waste with nutrient enrichment; T: Decomposed sugar mill
waste (press mud) without nutrient enrichment; T3
: Decomposed sugar mill waste
(press mud) with nutrient enrichment; 19
: Decomposed crop residues (rice straw) +
tannery waste with nutrient enrichment and ho: Decomposed crop residues (rice
straw) + press mud with nutrient enrichment. The experiment was laid out in a
randomized complete block design (RCBD) with 3 replications. The maximum plant
height (88.87 cm at harvest), number of total tillers per hill (17.71), number of
effective tillers per hill (13.43), length of panicle (24.50 cm), number of filled grain
per plant (91.40), grain yield (7.23 tlha), straw yield 12 (7.60 tlha), NPKS
concentrations and their uptake were obtained from 100% of the recommended NPKS
treatment. The performance of press mud was as good as the chemical fertilizer
treatment. Composts produced through nutrient enrichment increased yield of rice
compared to without nutrient enrichment during composting The application of
composts increased organic matter and NPKS content of post harvest soil.
