Why do we need to improve crop yield?
2. Why Do We Need to Improve Crop Yield? The reasons we need to increase crop production include: the world’s population continues to grow, with higher demand for food, livestock (which eat the crops produced), biofuels, fiber, food by-products, and a myriad of other crop-producing things.
What factors affect crop yield?
The four most important factors that influence crop yield are soil fertility, availability of water, climate, and diseases or pests. These factors can pose a significant risk to farms when they are not monitored and managed correctly.

How do you calculate yield per kg?
Calculate Yield.
For example, if 2 kilograms are harvested from 20 measured segments in a plot, each segment is 2 metres long, and average row spacing is 0.75 metres then: Grain yield (kg/ha) = (2 x 10,000)/(20 x 2 x 0.75) = 667 kg/ha.
How do you calculate crop productivity?
Crop productivity can then be calculated by dividing total production by the area from where the production came from. Ideally, sampling of harvest units is done just before storage and includes a measurement of the moisture content of the harvested product (Casley and Kumar, 1988).

Why does the soil need Levelling?
The levelling of ploughed fields prevents the top fertile soil from being carried away by strong winds or washed away by rain water. The levelling of ploughed fields helps in the uniform distribution of water in the fields during irrigation. The levelling of ploughed fields helps in preventing the loss of moisture.
