Advancements in farming techniques, utilization of fertilizers, and a robust economy are contributing factors to record crop production in recent years. Sample sizes of a harvested crop are measured to determine the estimated crop yield. The higher the yield and more intensive use of the farmland, the higher the productivity and profitability of a farm; this increases the well-being of farming families. Historically speaking, a major increase in crop yield took place in the early eighteenth century with the end of the ancient, wasteful cycle of the three-course system of crop rotation whereby a third of the land lay fallow every year and hence taken out of human food, and animal feed, production. So basically a “high yielding” crop might not be high yielding at all if it’s grown in conditions that are poorly suited to it, and as most high yielding crops are also fertilizer hogs with poor horizontal resistance and little to no consistent disease endurance they tend to do badly in general unless intensively coddled.
