"Whenever, then, the usual and ordinary rate of the profits of agricultural stock, and all the outgoings belonging to the cultivation of land, are together equal to the value of the whole produce, there can be no rent"

This quote by David Ricardo is referring to the idea of rent in economics. Rent is the settlement made by a lessee to a property owner for making use of land or other residential property. In this quote, Ricardo is stating that when the total cost of manufacturing (including the cost of labor, products, and also other expenditures) amounts to the complete value of the produce, then there is no lease. This means that the property owner does not get any kind of repayment for the use of the land. This principle is necessary in economics because it assists to discuss why some land is more valuable than others. For example, land that is more productive or has much better access to sources will be better and will certainly generate more rent than land that is less productive or has less sources. This quote by Ricardo is a tip that rental fee is established by the cost of manufacturing and also the worth of the fruit and vegetables, and also not by the property manager.
