Abstract
Agroforestry systems offer a sustainable
approach to land management by integrating trees with crops, optimizing
resource use, and enhancing productivity. This study examines the influence of
tree spacing and the distance from trees on the growth, yield attributes and
overall productivity of crops in agroforestry system. The experiment included
three tree spacing configurations (M₁: 2 m × 2 m, M₂: 3 m × 2 m, M₃: 4 m × 3 m)
and three inter-row distances from trees stem (S₁: 0.5 m, S₂: 1.0 m, S₃: 1.5
m), assessing their effects on key growth parameters such as plant height,
number of branches, dry matter accumulation, as well as yield components
including productive branches, pods per plant, pod length, grain weight, and
test weight. Results indicated that wider tree spacing (M₃) and greater
distance from trees (S₃) significantly enhanced plant growth and yield traits,
with M₃S₃ combination producing the tallest plants (78.50 cm), the highest
number of branches (12.67) and the greatest biomass (16.10 g). In terms of
yield, M₃S₃ recorded the highest grain yield (946.33 kg ha⁻¹) and biological
yield (2417.67 kg ha⁻¹), reflecting the positive effects of reduced competition
for light, water, and nutrients. These findings corroborate previous studies on
the benefits of optimizing tree spacing and intercrop positioning in
agroforestry systems to promote higher productivity and resource-use
efficiency. The study provides important insights for enhancing the design of
agroforestry systems, thereby contributing to more sustainable agricultural
practices that balance productivity and environmental stewardship.
