Detalles de la respuesta
A fixed factor of production in a crop production enterprise refers to a factor that remains constant regardless of the level of output. In this context, the size of the land is an example of a fixed factor of production because it is a fixed resource that cannot be increased or decreased in the short run. For instance, a farmer cannot quickly acquire additional land to produce more crops within a season. As such, the farmer must plan and manage the available land effectively to optimize crop yield and returns on investment.

Which of the following is not an effect of water-logging on crop production? it
Detalles de la respuesta
The correct answer is "causes plant roots to wilt". Waterlogging is a condition in which the soil becomes saturated with water, leading to the reduction or lack of oxygen available to plant roots. This situation can affect plant development by inhibiting the activities of microorganisms that are essential for nutrient availability, thereby reducing nutrient uptake and leading to the eventual death of plant roots. Waterlogging also encourages leaching, which is the loss of nutrients from the soil, leading to reduced crop yield. The condition does not cause plant roots to wilt. Instead, the roots become swollen and may turn brown or black due to lack of oxygen, leading to plant death.

Which of the following describes the effects of excessive nitrogen application on the growth of maize plants?
Detalles de la respuesta
Excessive nitrogen application on maize plants can have different effects depending on the stage of growth and the level of nitrogen applied. However, in general, the most common effect is high vegetative growth with low yield. This is because excess nitrogen encourages the plant to produce more leaves and stems at the expense of grain production. This phenomenon is commonly known as "luxury consumption" and can lead to taller, bushier plants that have a reduced ability to produce grains. Therefore, while nitrogen is essential for plant growth and development, excessive application can lead to negative consequences for maize production.

Which of the following sources of power supply to the farm is most unreliable?
Detalles de la respuesta
The most unreliable source of power supply to the farm among the options listed is wind. This is because wind energy is highly dependent on weather conditions, and its supply can vary greatly from day to day or even hour to hour. Wind turbines can only generate electricity when there is sufficient wind speed, and if the wind is too strong, the turbines have to be shut down to avoid damage. In addition, wind power generation requires large initial investments and can be affected by issues such as noise pollution and bird mortality. On the other hand, electricity, animal, and machine power can be more reliable as they are not as affected by weather conditions and can be controlled more easily.

Detalles de la respuesta
The growing of both forest trees and arable crops simultaneously on the same piece of land is called the taungya system. This system involves planting forest trees on a piece of land, and then, during the early stages of forest growth, intercropping with annual crops. The crops help to shade the trees, control weeds and increase the fertility of the soil. As the trees grow and mature, they are thinned to create more light for the remaining trees, which eventually form a dense forest canopy. The taungya system is often used in tropical countries as a way to provide both food and timber resources while also conserving the environment.

Detalles de la respuesta
The effect that is not a consequence of 'introduction' in crop improvement is "hampering the growth of local varieties." When a new crop is introduced, it may have various benefits, such as higher yield, improved quality, and faster maturity than local varieties. However, it does not necessarily mean that it will harm the growth of local varieties. In fact, sometimes the introduced crop can bring new genetic traits that can be crossed with the local variety to produce even better varieties. Therefore, the statement that "introduced crops hamper the growth of local varieties" is not a valid effect of crop introduction.

Detalles de la respuesta
When soils are poorly drained, the air content of the soil is reduced. Poorly drained soils are saturated with water which fills up the pores between the soil particles. As a result, the air content in the soil is reduced, leading to anaerobic conditions that can negatively affect plant growth. Oxygen is required for the respiration of roots and soil microorganisms, and without it, the rate of decomposition can be slowed down. Additionally, anaerobic conditions can lead to the production of toxic substances in the soil that can inhibit plant growth. Therefore, proper drainage is important for maintaining a healthy soil environment for plants to grow.
