The high yielding blackgram variety VBN 8 is a cross derivative of VBN 3 x VBG 04-008. Average yield of VBN 8 is 900 kg/ha which is 11.9 and 13.5 percent increased yield over the check varieties VBN 6 (804 kg/ha) and CO 6 (793) respectively. It matures in 65 – 70 days. Under irrigated condition, it performed well by recording 988 kg/ha and the yield increases was 15.29 and 22.28 per cent over the check varieties VBN 6 (857 kg/ha) and CO 6 (808 kg/ha) respectively. Under rainfed condition, this variety recorded 871 kg/ha with 23.20 and 25.87 per cent yield increase over the above checks varieties.
