The study was aimed to evaluate the effect of successive applications of
increasing biochar rates along with other mineral fertilizers and poultry
manure on onion nutrition and yield. The experiment consisted of 2
(agricultural year) × 11 (treatments) factorial combinations over two cropping years (2017 and 2018). Thus, 11 treatments were tested as follows: C
= control; MF = mineral fertilizer; PM = poultry manure; B1+ MF = 1 Mg
ha&#8722;1 of biochar+MF; B1+ PM = 1 Mg ha&#8722;1 of biochar+PM; B2+ MF = 2 Mg
ha&#8722;1 of biochar+MF; B2+ PM = 2 Mg ha&#8722;1 of biochar+PM; B4+ MF = 4 Mg
ha&#8722;1 of biochar+MF; B4+ PM = 4 Mg ha&#8722;1 of biochar+PM; B10
+ MF = 10 Mg ha&#8722;1 of biochar+MF; B10+ PM = 10 Mg ha&#8722;1 of biochar
+PM. The highest onion yield (39.9 Mg ha&#8722;1) was obtained in 2017 with
the biochar rate of 5.9 Mg ha&#8722;1 while an increase of 308 kg ha&#8722;1 in onion
yield was found for each Mg ha&#8722;1 of biochar added to soil in 2018. The use
of biochar combined with mineral fertilizers increased onion yield; and the
use of biochar combined with poultry manure improved soil fertility
status.
