Understanding Yield Percentage

Definition of Yield Percentage

Yield percentage can reflect the crop’s productivity and the farmer’s performance. It also refers to the expected amount or actual product that a farmer harvests compared to the predicted amount of the product produced. For example, the estimated yield for corn farming is 150 bushels per acre, and the actual harvest is 135 bushels. This means the farmer produces an expected yield percentage of 90%. Since the expected yield percentage will vary by location and crop, comparisons should match the same product and area.

Importance of Yield Percentage in Agriculture

The determination of yield percentage influences the economics of agricultural production directly. A low yield percentage impacts a farmer’s profitability, and improving yield percentage could make the difference between making and losing money. A higher yield leads to increased revenues and lower food costs, helping farmers reach their goals for a successful harvest.

Formula for Calculating Yield Percentage

The yield percentage formula to calculate crop production wealth is based on the amount of crop produced and the area of the land. One can use the following formula:

Yield Percentage = (Actual Yield per acre / Expected Yield per acre) * 100

Calculating Yield Percentage: A Step-by-Step Guide

Understanding the Variables

The first step in calculating yield percentage is to know the variables such as how much ground is being planted and its productivity. Other variables might also include weather conditions, which could influence the yield. For getting accurate yield percentage results, farmers and growers need to measure the area used for cultivation and the actual crop produced.

Estimating Harvest Yield

To calculate yield percentage, you must calculate the amount of crop produced. The amount of crop produced arises from the farmer’s investments, such as the seedlings and fertilizer used to cultivate the land. To estimate the crop yield, farmers could use historical harvest records from previous years to give insight into possible crop levels. Other ways to compute crop yields include labor-intensive methods like plant counts or using remote sensing technologies and automated record-keeping platforms like Croptracker, Tend or FarmLogs.

Preparation of Harvested Produce

The next step involves preparing the harvested crops for final marketing. The proportion of marketed products to total harvests will depend on the destination and the other ancillary products that can arise from yields.

Calculation of Yield Percentage

Once the prepared product is ready for sale, the calculation of yield percentage is primarily a matter of subtracting expected yield from the actual harvest, dividing the result by the expected yield, and multiplying the quotient by hundred to make the result a percentage.

If the expected crop on one acre of land is 200 bushels with actual production of 170, the yield rate is calculated as follows:

Yield Percentage = (170/200) * 100

The final result is a yield rate of 85 percent.

Factors that Affect Yield Percentage

Soil Conditions

The physical properties of soil, including its texture, nutrient content, soil structure, and pH level, all affect crop yield. If the soil is nutrient-poor or contains harmful if not toxic chemicals, crops may not grow robustly or at all. Therefore, soil testing in a particularly new farm area is crucial before planting crops.

Weather Patterns

The amount of sunlight and rainfall, extreme temperatures, and climatic conditions all play a crucial role in crop yield. The ideal time and the number of days for planting a crop will depend on the seasonal weather variances that a particular region experiences. Therefore, farmers have to factor in these conditions before they plant the crop entirely.

Growing Methods

The way in which crops are planted, cultivated and harvested can affect yield percentages. For example, crop rotation, fertilization methods, use of herbicides and applied pesticides all impact crop yield. Specialty crop management like pruning and trellising or indenting and caging your crops will occur in both natural and greenhouses environments. The correct method of managing the crops ensures farmers can optimize crop productivity and generate better profits.

Pest and Disease Management Techniques

Controlling pests and diseases that can ruin crops is a critical consideration for farmers and growers. Using preventative measures to protect their crops can save farmers money in the long run. Disease-resistant seedlings, regular crop monitoring, and using organic methods to deter pests such as insects and birds, all assist in the management of pests and disease problems, enhancing yield percentages.

Tips for Increasing Yield Percentage

Choosing the Right Seeds

The choice of seeds can impact yield percentage. Farmers should choose seeds best suited for the soil type, location, and weather in their region for maximum yield. Also, farmers have to take into account hybrid varieties of crops, available in the market that help them optimize their yield production.

Proper Fertilization Techniques

Farmers should conduct a soil analysis to determine nutrient deficiency in the soil. The correct method for fertilizing the soil will help the crops to gain the necessary nutrients and ultimately increase their yield rate. Farmers have to use organic fertilizers or chemical-based formulae after understanding the soil type and nutrient richness.

Proper Watering Techniques

Watering crops evenly, giving enough water is essential to maximizing crop yield. With less water, crops will wilt, and with more watercomes parasitism, the excess water won’t contribute to the crop’s yield either. Farmers should use the right method of irrigation to ensure proper watering and prevent soil leaching.

Crop Rotation

Crop rotation entails planting alternating crops instead of only one crop alone in a field; it not only reduces disease and pests problems but increases soil fertility. Rotating different crops in different seasons lets the soil regenerate the necessary nutrients allowing the next crop to grow more efficiently, increasing yield percentage.

Examples of Different Crops and Their Yield Percentages


Corn yield percentage can vary depending on the planted crop type, the soil type, and growing region.
In the United States, the average corn yield falls between $177$ and $181$ bushels per acre, roughly a Montana’s square mile area of land per year, which is slightly lower than the world average.


Wheat yields can fall between $299$ to $406$ bushels per acre, depending on the location and cultivation techniques. For example, in Morocco, wheat yields are usually around 1 and a half tons per feddan, a unit of land commonly used in Egypt, which is just over 1 acre.


Tomato plants could yield between $29$ to $120$ tons per acre, depending on the amount of sunlight, rainfall, soil moisture, and how well it is maintained. The ideal temperature for growing tomatoes lies around 60-65 F. When the temperature falls below 50 F, it affects plant growth, reducing yield percentages.


Grapes yield much better in warmer climes, such as in Chile, where yields vary between 8 to 20 tons per hectare, which is equal to just under 3 football fields. In contrast, in Germany, where temperatures are lower, the yield per hectare ranges between 4 and 10 tons per hectare.

Economic Implications of Yield Percentage

Effects on Price

Crop yield percentage affects pricing by directly impacting the supply and demand of the agricultural product. For example, if there is a high yield of a particular crop, the supply will increase, and consequently, the price would go down. The opposite is also true; low crop yields will increase demand as the premium product becomes scarce, pushing prices upwards.

Effects on Profitability

Yield percentage affects agricultural profitability directly. A higher yield percentage means more profit. An increase in harvest yields can help farmers cover production costs and reinvest into their farming. Low yield percentages could lead to a potential loss of revenue and impact the profitability of farming operations negatively.

Importance for Farmers and Growers

The importance of yield percentage for farmers and growers is to optimize their harvest, reduce operating expenses, and increase profitability. By increasing yield percentages, farmers and growers increase their revenue and grow their businesses that positively impact their communities by producing a more abundant and healthier food supply.


The calculation of yield percentage allows farmers and growers to improve their crop production and optimize the economic performance of their farms. The process involves taking care of numerous factors, including the correct choice of crops, fertilization techniques, watering, and crop rotation. As farmers and growers, it is crucial to investing the necessary effort to increase yield percentage, as it ultimately makes a significant difference in the profitability of the business and the food prices that consumers pay.

The relationship between yield percentage, economic implications, the environment, and food production indicates the importance of farmers and growers continually seeking better ways to optimize yield production, reduce operating expenses, embrace new technologies, and maintain sustainable farming practices.
