For farmers, time is money. In the case of organic farming, the amount of time the fruits and vegetables would grow is slower than those grown inorganically. Not only that the time of harvest takes a long time, the labor is more intensive than inorganic farming.
More maintenance is needed in order for the produce to pass the selective quality specification set for organic foods. Because of this, the yield of organic farming is lower than that of inorganic farming making it a bit more expensive than goods produced inorganically.
