• Blackgram VBN-8 is a high-yielding, determinate variety known for its short duration (65-70 days), excellent resistance to Mungbean Yellow Mosaic Virus (MYMV) and Leaf Crinkle Virus, and suitability for rice fallow lands in South India, offering significant yield increases over older varieties like VBN 6 and CO 6. Key features include synchronized maturity, high protein content (around 21.9%), and good performance under both irrigated and rainfed conditions, making it a popular choice for farmers in Tamil Nadu, Andhra Pradesh, and Karnataka. 

        Key Characteristics:

• Maturity: Short duration, maturing in 65–70 days.
• Yield: High yielding, averaging around 900 kg/ha. Shows about 15.3% yield increase under irrigated conditions and even higher gains (over 23%) under rainfed conditions compared to checks.
• Disease Resistance: Highly resistant to MYMV, resistant to Leaf Crinkle Virus, and moderately resistant to Powdery Mildew.
• Plant Type: Determinate, with synchronized maturity (pods mature together).
• Suitable Zones: Recommended for South Zone (SZ) states like Andhra Pradesh, Tamil Nadu, Karnataka, and Odisha, especially for rice fallows.
• Grain Quality: Contains approximately 21.9% protein. Hard seeds have thicker cuticles and more structural components like pectin, cellulose, and lignin. 
• Adaptability: Performs well in rice fallow systems.
