A device to induce pollination in tomatoes grown out of season has been developed. Two prototypes versions were constructed: one tractor-mounted for field-grown tomatoes and one back-pack model for greenhouse-grown tomatoes. Both models employ a pulsating air jet as a vibration energy carrier. In field tests the use of these prototypes resulted in an increased pollination rate and greater yield of tomatoes.
