Abstract:

Demonstrations are the one of the most important tool for transfer of technology at grass root level that directly impacts the spread of technology. Onion is grown in kharif, late kharif and Rabi seasons in India, major onion grown in Rabi season all over India, but it’s cultivated on upland in kharif/ late kharif all over India. Even though its productivity recorded is low due to lacking in knowledge of scientific production technology and high yielding variety suitable to soil and climate. In order to increase the productivity of kharif onion with adoption of improved technology, 80 no’s of demonstration in 20 hectare on onion variety Agrifound Dark Red (ADR) were conducted during 2014-15 by National Horticultural Research and Development Foundation, in different locations of three states viz Bihar, Rajasthan and Gujarat state through TDTD (Technology Dissemination through Demonstration) under National Horticulture Mission at selected farmers’ fields. From the conducted demonstrations, it was revealed that, an average increased yield of onion crop 15.82% was achieved with average technology gap of 42.92 q/ha of onion bulb production. Also reduce technology index of 17.17 % was noticed during the year. The onion produced higher yield (average 207.08 q/ha) on demonstrations plot over locally available variety (average 178.80 q/ha) on control plot but remain behind to touch its potential yield (250 q/ha). The gross returns, net returns and B: C Ratio was recorded higher in Gujarat state followed by Rajasthan and Bihar on demonstration plot compared to control. Further the technology index was lower and its adoption index were also highest in demonstration plot of Gujarat and technology index was highest its adoption index were lowest in demonstration plot of Bihar state as well as control plot. The monetary returns were found to be influenced by crop yield and prevailing market prices of the produce. During all the years of demonstration, higher monetary returns with benefit: cost ration were obtained from the technology demonstrated plots as compared to farmers control plot. An increased average net maximum monetary return of Rs 471820.00 with B:C ratio 5.78 was obtained in demonstrations plot of Gujarat while lowest in Bihar Rs 333200.00 and B: C ratio 5.12 was obtained in the demonstrated technology over control plot with average net monetary returns Rs 218500.00 and B: C 3.87. The higher returns was due to higher bulbs yields as well as higher market price with sorting/grading of bulbs obtained in the demonstration technology over control plots. Obtained maximum onion bulb yield with higher monetary returns, B:C ratio, higher adoption index, reduction in technology index % & extension gap Qtl/ ha in Gujarat State, whereas Obtained minimum onion bulb yield with lower monetary returns with B:C ratio, lower adoption index, maximum technology index % & maximum extension gap Qtl/ ha in Bihar state.
