Abstract:

Napier Grass is used as fodder for feeding livestock in India and can also be used in CBG plants to generate biogas that is clean, less polluting and a good renewable source of energy. It is grown mostly in tropical regions and gives yield throughout the year.

Due to the shortage of green fodder in the country, Napier grass was introduced to overcome the shortage which also impacts the milk production of animals and affects our demand in the long run. After the study done in U.P (BULANDSHAHAR and Bareilly District) and Tamil Nadu (Vadhavathur Village, Namakkal District), it is concluded that the productivity and profit of Napier grass are almost twice as compared to the traditional crops like Sorghum and Bajra.

In BULANDSHAHAR District, Napier grass CO-4 is mainly cultivated which gives a yield of 466.66 quintals every 4 months. In the Bareilly district, the main focus is on the B-N Napier grass variety where the yield is 400 quintals every 4 months. In Namakkal district, Vadavathur Village the main focus is always on Cumbu Napier grass CO-4 and Cumbu Napier grass CO(BN) 5 which gives a yield of 666.66 and 733.33 quintals every 4 months.

The soil quality is not affected by cultivating Napier grass and the fertility of the soil is improved. Napier grass succeeded in carbon sequestration. Due to its high dry matter content and yield Napier grass has the potential to generate biogas and hence produce electricity.

The milk production and income of the farmers have improved over time. Farmers have earned more than 1 lakhs in Tamil Nadu whereas sorghum and Bajra provided less income which shows the gross profit of cultivating Napier grass in the long run. Napier grass must be adopted by every state in India.
