Towards Sustainable Management of Pineapple Residues
Studies were conducted to: (i) Investigate the effect of the modification of the existing N, P, and K programme and residue management practice on pineapple fruit yield, (ii) Compare the economic viability of in situ decomposition of pineapple residues untouched (lDPR), i.e. stacking of pineapple...

| description | Studies were conducted to: (i) Investigate the effect of the modification of the
existing N, P, and K programme and residue management practice on pineapple
fruit yield, (ii) Compare the economic viability of in situ decomposition of
pineapple residues untouched (lDPR), i.e. stacking of pineapple residue (leaves,
crowns, and peduncles) slashed and raked from 0.60 m x 10 m rows into 0.90 m x
10 m rows (ZBT-zero burn technique), and in situ burning pineapple residues
(IBPR) (iii) Quantify the amount of humic acid (HA) that could be extracted from
composted pineapple leaves using 0.10M potassium hydroxide (KOH) produced
from pineapple leaves and that of analytical grade (0. 10M KOH), (iv) Compare the
elemental composition (C, H, N, 0, and S), functional groups (carboxylic,
phenolic OH, and total acidity), and spectral characteristics of HA extracted from
composted pineapple leaves using KOH from pineapple leaves and that of
analytical grade, and (v) Investigate the potential value added agricultural products
that could be produced from pineapple leaves. |
