The effect of 10, 100, 1000, 10,000 ppm of ethylene, applied for 3, 6, 12, and 24 hours, on the ripening rate of "Hass" avocado (Persea americana Mill.) fruits at three stages of maturity was investigated. Ethylene treatments were started either immediately after picking or 2 days later. A sharp peak of ethylene production was found to precede full softening by about 2 days and the occurrence o...

The experiment was conducted at Sher-e-Bangla Agricultural University farm, Dhaka, Bangladesh during the period from March to June 2007 with seven treatments viz; T1: Hand picking of infested fruits of bitter gourd at 7 days interval; T2: Neem seed kernel at 5 gm/l of water at 5 days interval +T1; T3: Spray of shobicron 425EC @ 2ml/l of water at 7 days interval + T1; T4: Micronutrient-Zn @ 6.72...

Citrus harvesting is time-intensive and labor-intensive, relying mainly on manual harvesting. The automatic of fruit vegetable crops can not only reduce the physical labor farmers in harsh field environment but also greatly improve efficiency. Based principle citrus picking, an end-effector with three-finger grasping designed this study. First, structure was to achieve function stable effective...

The physiological breakdown of citrus fruits variously known as storage spot, pitting, or pox has presented a perplexing problem to growers and shippers ever since the storage and transportation of these fruits was undertaken on an extensive scale. This breakdown manifests itself in various forms of blemishes of the rind, depending on such factors as the inherent condition of the fruit, the tem...

In order to use the resonance principle for vibratory picking of Camellia oleifera fruit, frequency sweep tests were carried out on fruiting branches trees. The results showed that acceleration response fruit-bearing had good consistency. fruit removal rate alone evaluate effect is not reliable, and introduction energy utilization vibration significant. best a 8 Hz an excitation time 10 s. was ...

Double-arm picking robots are widely used in agricultural production for their high collaborative efficiency. While picking, area planning and collision detection between the mechanical arms is a crucial challenge double-arm robot, which needs to establish collision-free path fruit picking. In this study, we developed cooperation method robotic of kiwifruit. Firstly, problem dividing was simpli...

Achieving a low cost robotic arm is crucial in agricultural applications. Task based optimization of the robot kinematics influence the robot simplicity and cost. Nevertheless, the environment of the robot also has a major influence on its simplicity. We have simulated a variety of orchard architectures and searched for an optimal robot design for each architecture. From the training systems wh...
