A healthy orchard necessitates well-balanced nutrition. In order to achieve a high yield, fertilizer application in the
proper amount and position is important. Existing fertilizer application methods (band placement, pellet application, and
ring basin method) have limitations such as excessive fertilizer application, soil acidity, nutrient imbalance, soil structure
damage, bulk density rise, and more. A spot fertilizer applicator that can dispense the proper amount of fertilizer at right site
can reduce fertilizer waste, lowering pollution and input costs. As a result, a novel grooved belt type metering system was
designed with an autonomous plant detection-based spot fertilizer application. The fertilizer placement and consistency of
amount dispensed per plant of the applicator were assessed in the lab. The independent parameters were metering belt
groove volume (50, 100 and 150 cm3), metering belt speed (8, 9 and 10 m.min−1), plant spacing (45, 60, 75 and 90 cm) and
forward speed (2, 2.5 and 3 km.h−1). Forward speed had a considerable impact on the band length, whereas groove volume
and belt speed had a substantial impact on the lateral placement parameters. Because plant spacing had no significant effect
and the means of real and measured fertilizer application amounts were equal, the machine was found suitable for applying
fertilizer with any plant spacing. Using a full factorial experimental design, the optimal values for independent parameters
such as groove volume, plant spacing, belt speed, and forward speed were assessed 50 cm3, 78.4 cm, 8.74 m.min−1, and
2.72 km.h−1, respectively with a high desirability of 0.971. In comparison to mechanical sensing type available spot fertilizer
applicators, the developed spot fertilizer applicator required half the sensing and actuation time and had three times less
fluctuation in fertilizer dosing.
