description |
Paddy husk (PH) and corn stalk (CS) residues are usually disposed through
open burning. Compost could instead be produced from these residues.
Composting is the conversion of organic residues into useful organic soil
amendments that provide nutrients to crops and enhance the tilth, fertility,
and productivity of soils. However, some composting methods are not
effective in producing good quality compost. Therefore, this study was
conducted to develop an effective way of utilising these residues by
composting with indigenous microorganisms (IMO). Inoculated bacteria from
steamed white rice (SWR), aerated fish pond water (AFPW), and kitchen
wastes (KW) were used. Composting was conducted in a white polystyrene
box measuring 30 x 15 x 25 cm and attained an ambient temperature of
25.8˚C for 34 days. The composts were analyzed for C/N and C/P ratios, pH
(H2O and KCl), nutrient content, organic carbon, organic matter, ash, Cation
Exchange Capacity (CEC), humic acid (HAs), acidic functional groups, E4/E6
ratio, spectral, and microbial count. IMO-composts were blackish in colour
without foul odours which indicate the stable nature of the composts. IMOcompost
from corn stalk residues using aerated fish pond water (AFPW)
inoculants showed higher positive relationship of HA with total N, P, K, C/N
and C/P ratio, pH, TOC, OM, and CEC compared to the other treatments.
Identifying bacterial through FAME analysis for three different IMO sources,
SWR, AFPW and KW showed the following five beneficial bacteria; Bacillus
cereus from SWR, AFPW and KW, Bacillus sphaericus from KW, Bacillus
megaterium from SWR, Acinetobacter calcoaceticus from KW and
Microbacterium barkeri from AFPW. IMO-composts were further tested in a
pot experiment (shelter rain house) whereby Sweet Corn (D56) variety of
maize (Zea mays L.) was used as the test crop to evaluate the effect of IMOcompost
on nutrient use efficiency by maize. The treatments evaluated
were: (T0) no fertilization, (T1) N, P and K (4.84g urea + 2.48g muriate of
potast (MOP) + 4.91g triple super phosphate (TSP)), (T2) 77.96g IMO(V)-
compost(SWR-PH) + 0.72g MOP + 1.41g TSP, (T3) 74.54g IMO(V)-
compost(SWR-CS) + 0.00g MOP + 0.64g TSP, (T4) 57.90g IMO(V)-
compost(AFPW-PH) + 0.29g MOP + 2.35g TSP, (T5) 38.72g IMO(V)-
compost(AFPW-CS) + 0.15g MOP + 2.48g TSP, (T6) 59.49g IMO(V)-
compost(KW-PH) + 0.28g MOP + 2.32g TSP, and (T7) 51.41g IMO(V)- compost(KW-CS) + 0.04g MOP + 2.01g TSP. Application of chemical fertilizer
was done on 10th and 28th day after sowing (DAS). Sandy clay loam Typic
Tualemkuts (Bekenu Series) was used as the growth medium. The plants
were harvested on the 50th day after sowing (DAS) during tassel stage. The
plant parts (leaves, stems, and roots) were analyzed for N, P, and K and soil
samples were analyzed for exchangeable K, Ca, Mg, and Na, CEC, organic
matter, organic carbon, total N, available P and pH. Analysis of variance was
used to detect treatment effect while Tukey’s test was used to compare
treatment means. Application of IMO-compost affected soil pH,
exchangeable cations, CEC, organic carbon, OM and available P compared
to the control treatment (T0). The IMO-compost had no significant effect on
total N. IMO-compost (steamed white rice (SWR) inoculants), (T3) had

pond water (AFPW) inoculants), T5 had significant effect on N, P and K
contents, their uptake, as well as their use efficiency by maize. This method
was able to significantly reduce N, P and K application. It can be concluded
that mature compost from corn stalk (CS) residue with aerated fish pond
