Abstract
Wheat (Triticum aestivum L.) is the second most important crop after rice in India. Wheat crop is affected by high terminal heat stress. The available varieties does not offer high yields. Disease Infestation at vegetative and growth phase is often observed which affects the yield and hence income of the farmers. Thus development of short duration, heat tolerant, high yielding, and disease resistant varieties is seen as a viable option for preventing yield losses in this region. ICAR-Indian Institute of Wheat and Barley Research, Karnal- Haryana has developed 3 high yielding varieties DBW-173, DBW- 187 and DBW-222 which offers yield per acre in the range 24- 27q/acre. These varieties offer resistance to different diseases. Through our research trial we have evaluated the agronomic performance of these high yielding varieties. The trial was conducted at our R&D centre located at, Chidana, Sonipat. The experiment had 3 treatments, Treatment 1 Wheat Nursery of these varieties were raised hydroponically and transplanted in soil. In treatment 2 mycorrizal compost was added while transplantation in soil and in Treatment 3 wheat was sown with traditional broadcasting method. We observed that the highest yield was observed in DBW- 187 follwoed by DBW-222& DBW-173. The results of treatment 1 and 2 were better than treatment 3 in terms of maturity, lodging, disease infestation and crop yield.
