Precision seeders place single seeds at predetermined intervals in evenly spaced rows to provide an optimum plant population using pretreated seeds suited to mechanical metering under gravity and with high germination and establishment potential. Plants with lesser germination potential or those requiring an earlier growing date (rice, tomatoes, cabbage, lettuce, tobacco) may be transplanted typically in biodegradable containers in which the seedling has been established in greenhouses.
The harvesting of delicate fruits (strawberries, raspberries, grapes, plums) and vegetables (tomatoes, mushrooms, lettuce) for the fresh market has not been successfully completed despite a substantial investment in crop breeding and mechanization research. Machines that can harvest such delicate biological tissues, generally inflict too much damage on a product destined for the fresh market but have been successful with product destined for processing. Selective harvesting is another substantial challenge facing researchers in the fruit and vegetable sector in particular.
