Pesticides are sprayed on crops to control pests such as insects, weeds, and diseases that can damage the crops and reduce their yield. This helps to protect the crops and ensure a successful harvest.
I don't know what the world average is, but the US average is around 8,800 kilograms per hectare for the grain yield.
There are several insects that affect maize including earwigs, weevils and armyworms. The most common pest is the European corn borer that led to the development of a form of maize called Bit maize which has proved resistant to these insect.
the insects don't eat/ damage crops and it allows to kill insects carrying plant disease.
Maize grows best in well-draining soil that is rich in organic matter, with a slightly acidic to neutral pH of 6.0-7.5. Sandy loam or loam soil types are generally preferred for optimal growth and yield of maize.
As of the latest data, the average maize yield in Zambia is approximately 2.5 to 3.0 metric tons per hectare. However, this figure can vary significantly based on factors such as farming practices, climate conditions, and access to inputs like fertilizers and improved seed varieties. Efforts to enhance agricultural productivity continue, influencing future yield potential.
That all depends on where you live, the yield of the corn crop, and how large of an area you want your animals to graze.
Maize prefers well-drained, fertile soils with a pH of 6.0-7.5. Sandy loam or loam soils are ideal for maize cultivation as they allow for good root development and water infiltration, resulting in optimal growth and yield. Adequate soil moisture and nutrient content are also essential for successful maize production.

K. Subedi has written: 'Assessment of the major yield limiting constraints of maize production at Lumle condition.'
The yield of maize can vary significantly based on factors such as soil quality, climate, and farming practices. On average, a hectare of maize can produce between 5 to 10 tons under good conditions. In optimized agricultural settings with high-yield varieties and effective management, yields can exceed 12 tons per hectare. However, local conditions and farming techniques play a crucial role in determining actual outcomes.
Maize is primarily wind-pollinated, as the male flowers (tassels) release pollen that is carried by the wind to the female flowers (silks) for fertilization. Insects can also play a role in maize pollination, but wind is the dominant method.
