Effect of green manuring on rice performance
Front Line Demonstrations with introduction of green manuring crop Dhaincha (Sesbania rostrata) has been conducted by Krishi Vigyan Kendra, East Kameng district, Arunachal Pradesh, India. The soil was slightly acidic in reaction (pH 5.5 to 6.0), sandy loam in texture with rich in organic matter content, medium in phosphorous and potash content. Sesbania were sown@ 45 kg/ha. 8 weeks old green manuring crops were chopped into pieces and incorporated in the soil. With the incorporation of green manure crop, average rice yield was increased 25.5%. The average net return was recorded to be Rs. 29177, against the average net return of farmers’ practice of Rs. 20863. The Organic Carbon content (%) and Available Nitrogen content (kg/ha) was increased considerably due to incorporation of green manure in rice field.
