Abstract
The study was conducted to determine the growth response of white corn and therate of biochar that can provide the highest yield and evaluate the most economical combination of treatments. The treatments evaluated were T1 (Inorganic fertilizer); T2 (RHB). T3 (IF + 5.33 t ha-1 of RHB); and T7 (IF + 6.67 t ha-1 of RHB).
The egronomic and yield performance of white corn in terms of number of days to tasseling, silking, maturity, plant height, ear length and diameter, number of kernel per ear and the yield were significantly increased by the supplementation of the lowest amount of biochar (1.33 t ha-1) to IF which had the best effect of all the treatments. This treatment also gave the highest yield about 3.7 t ha-1 and highest net income. On the other hand, the lowest net income (negative) and yield was obtained on the treatment that was purely applied with RHB (4 t ha-1) which was 0.14 t ha-1.
This study revealed a promising result of biocahr in increasing yield and net income of corn production particularly supplementation of rice hull biochar (RHB) lower than the recommended rate (1.33 t ha-1). Hence, this amount of biochar was recommended as supplement to inorganic fertilizer to improve corn productivity during wet season.
