Grain yield (kg/ha)

Irrigated 7400 6.7 tonnes of tender cobs & 32.3 tonnes of green fodder / ha
Rainfed 5000 3 tonnes of tender cobs per ha.
Special features High starch (76.30 %), high protein (11.25%) and high beta- carotein (0.48 mg/100g) with moderate level of fat (4.65 %) and crude fibre (1.25%). High shelling (81%) with high test weight (400 g /1000 seeds). Multiple disease resistance to Sorghum downy mildew, Maydisleaf blight, Turcicum leaf blight, Post flowering stock rot and Banded leaf and sheath blight. Moderately resistant to stem borer. Hybrid seed production is much easier since male and female parents can be sown simultaneously for flowering synchronization. 2 to 3 cobs / plant, possessing delightful sweet taste and flavour Suitable for inland and export market Green fodder has good forage value.
