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.

Drought-tolerant crop varieties help mitigate the impact of drought by providing farmers with resilient options that can withstand water scarcity, maintain yields even during dry periods, and contribute to food security and agricultural sustainability in drought-prone regions.

Scientists have developed crop varieties that can tolerate drought conditions by possessing traits such as deep root systems, efficient water use, and the ability to maintain growth and productivity under limited water availability.
