Fertilizers are commercially produced plant nutrients containing nitrogen, phosphorus, and potassium, vital for healthy vegetative growth.

Examples of plants used for green manure include sun hemp, guar, clover, vetch, and ryegrass.

Green manure enriches soil fertility by adding nitrogen and phosphorus as the green plants decompose, enhancing soil nutrient levels.

Green manure refers to plants like sun hemp or guar that are grown and then ploughed into the soil before sowing crop seeds to enrich it with nutrients.

In India, various irrigation systems are employed to cater to the diverse water resources and climates. These include well irrigation, canal irrigation, river irrigation, and tank irrigation.
