how do we increase the yield of crops and livestock?
Answers
1. Plant them in places conducive to growth
2. Put water on them
3. Put fertilizer on them
4. Remove weeds from the area around the more desirable plants
5. Remove insects (and other animals) from the area around the crops
6. Determine the optimal spacing for the plants, and plant them that way
7. Determine the optimal fertilizers in terms of both "what" and "how much" and apply them that way
8. Follow good crop rotation / leaving fallow schedule to
reduce soil nutrient depletion;
and/or reduce things like selenium contamination which come from using a substandard water supply
9. Occasional plowing before planting can break up old root clumps and give the new plants a better chance at growing their own roots. Do not overdo (which can lead to accidental wind blowing away of the topsoil).
10. Selective breeding of plants for improved per-acre yield. This can include breeding for response to fertilizers, salt tolerance, disease resistance.
11. Genetic engineering of crop plants for improved nutritional value, improved disease resistance, resistance to herbicides.
Lifestock:
1. Make sure the animals get adequate food and water
2. Selectively breed the animals for weight gain per unit food
3. Give the animals better quality food
4. Bring the food to the animals rather than bringing the animals to food. This means less energy is wasted in walking to and from pastures and that means more weight is put on.

we can use hybridisation method.
