Integrated Crop Management Practices Resulted in Higher Yield in Sorghum (Sorghum bicolor L.)

ICAR-Krishi Vigyan Kendra, Kalaburagi-II conducted cluster demonstrations programmes during the year

2018 to 2021 to demonstrate scientific cultivation of sorghum through improved crop management at farmers field in the villages namely, Rasanagi (Jewargi Taluka), Beeranahalli village (Sedum Taluka) and Malaga (K) Chittapur Taluka of Kalaburagi district. The results showed the low incidence of shootfly, Atherigona soccata (Rondani)(3.18%), fall army worm,Spodoptera fruziperda (1.10 No.larvae/plant), stem borer, Chilo partillus (2.63%), Mirid bugs, Perigranus maidis (2.30), aphids, Rhopalosiphum maidis (8.03) and smut diseases (1.20%) in the demonstration plots as compared to the farmers’ practice which were recorded the 10.35 per cent, 3.53, 10.50, 8.52, 22.92 and 6.82 per cent in 2018–19, 2019–20 and 2020–21 successive years, respectively. The average grain yield was higher in the demonstration plot (10.06 q/ha) than the farmers’ practice (8.37 q/ha) it means 19.39 per cent yield increase over farmers’ practices. Further, it was recorded that, higher gross return, net return and B: C ratio of the scientific improved technology as compared to farmers practices.
