Bridging the yield gap of mung bean through cluster frontline demonstration in Erode district

Mung bean (Vigna radiata L) or green gram is one of the important pulse crop cultivated over 2000 ha area in Erode district of TamilNadu. Attempts were made to bridge the yield gap of mung bean by adopting integrated crop management practices through cluster frontline demonstrations. The integrated crop management practices comprised of introduction of high yielding variety, seed treatment, integrated nutrient and plant protection measures were demonstrated. The cluster demonstrations were conducted during 2017-2022 in 225 locations. The results showed that higher seed yield of 811 kg/ha was recorded in demonstration plots compared to 715 kg/ha in farmers’ practice with a yield advantage of 13.6%. The average extension gap, technology gap and technology index were 97 kg/ha, 61.8 kg/ha and 7.1%, respectively. The integrated crop management practices gave higher benefit cost ratio of 2.23 compared to farmers’ practices.
