Abstract

The little millet variety DHLM-14-1 developed at the Agricultural Research Station (ARS) Hanumanamatti under the University of Agricultural Sciences, Dharwad. With a maturation period of 85-90 days, this variety features an erect, tall plant stature ranging from 112 to 130 cm and produces bold, oval-shaped gray grains. DHLM-14-1 stands out for its notable tolerance to shoot fly, exhibiting only a 13.89% incidence compared to 19.15% in the national check JK-8. Its impressive yield performance is evident, yielding 18.42%, 30.58%, and 3.14% more than the national checks OLM-203, JK-8, and KOPLM-53, respectively, making it a beneficial option for millet producers looking for resilient, high-yielding crops. Across trials conducted from 2011 to 2014, DHLM-14-1 showcased exceptional agronomic performance, achieving a mean seed yield of 42.41q/ha, significantly outperforming local check TNAU-63 and national check OLM-203 by 26.63% and 23.75%, respectively. Its consistent yield superiority, with an average of 15.89 q/ha over three years, illustrates the cultivar's adaptability to diverse agro-climatic conditions, surpassing OLM-203 and JK-8 by 18.42% and 30.58%. Recognized during the 29th Annual Group Meeting of the ICAR All India Coordinated Research Project on small millets, DHLM-14-1 has shown strong disease resistance against grain smut, brown spot, and sheath blight, with disease incidences similar to OLM-203 and significantly lower than JK-8. Additionally, its effective resistance to shoot fly underscores its potential to reduce pest damage, reinforcing DHLM-14-1's value as a high-yielding, resilient cultivar that not only enhances sustainable millet production but also supports food security and improves farmer livelihoods across India.
