Abstract
The integration of coconut shell biochar with
inorganic fertilizers can enhance crop productivity and soil fertility. A
polybag experiment was conducted at the University Farm, Eastern University,
Sri Lanka, to evaluate the effects of coconut shell biochar combined with
different levels of inorganic fertilizers on the growth and yield of Cucumis
anguria L. (var. Chandani). The experiment used a Completely Randomized
Design (CRD) with six treatments and five replicates: T1 (100% inorganic
fertilizer), T2 (100% coconut shell biochar 22 t/ha), T3 (25% inorganic
fertilizer + coconut shell biochar 22 t/ha), T4 (50% inorganic fertilizer +
coconut shell biochar 22 t/ha), T5 (75% inorganic fertilizer + coconut shell
biochar 22 t/ha), and T6 (100% inorganic fertilizer + coconut shell biochar 22
t/ha). Crop growth and yield were recorded from 2 to 8 weeks after planting.
Results showed that T6 significantly improved vine length (14.38%), number of
branches (28.94%), leaves (11%), chlorophyll content (16.23%), leaf area
(42.35%), shoot fresh weight (42.73%), shoot dry weight (46.30%), root fresh
weight (31.79%), root dry weight (36.04%), fruit number (46.30%), yield per
vine (68.18%), and total yield (69.32%) compared to T1. These findings
highlight the potential of integrating Coconut shell biochar with 100%
inorganic fertilizer application to enhance Cucumis anguria growth and
yield, which is environmentally friendly and contributes to sustainable
agriculture.
