Growing a single crop species over a large area or farm is called intensive farming or monoculture. Earlier practices of mixed cropping caused problems in crop management, like harvesting, etc. Uniformity in plant height adds beauty to our fields and makes the application of agrochemicals easy. It also saves time and energy in segregating grains in threshing.

The dry weight of organic matter produced by plants, their derivatives and wastes are called as BIOMASS. The biomass includes crop residues, plant parts, body parts of dead animals and animal wastes. As biomass is created due to photosynthesis by plants, so energy from biomass or bio wastes is regarded as another form of solar energy.
The positive movements of a plant shoot in response to light or movement of shoot towards the source of light is called as Phototropism. If the part of a plant moves away from light, this movement is called as Negative Phototropism.
