Cabbage (
Brassica oleracea var.
capitata L.), one of the world’s most widely cultivated cole crops, plays a critical role in food and nutritional security due to its high content of vitamins, minerals, fibre, and bioactive compounds. Despite its importance, productivity in the Churachandpur district of Manipur remains significantly lower than the national average, primarily due to the non-adoption of improved varieties and scientific cultivation practices. To address this gap, ICAR - Krishi Vigyan Kendra (KVK), Churachandpur under ICAR
-NEH Region conducted 20 Frontline Demonstrations (FLDs) during four consecutive rabi seasons (2012
-13 to 2015
-16) using the improved variety ‘Green Hero’ along with recommended production technologies. The objective was to assess performance, quantify yield gaps, evaluate technology index, and analyse farmer adoption under real field conditions.
Results revealed that demonstration yields ranged from 320-335 q/ha, significantly surpassing existing farmers' practice yields of only 140 q/ha. The percent increase in yield due to adoption of improved practices varied from 128.57% to 139.29%. Extension gaps were found between 180-195 q/ha, while technology gaps decreased from 80 q/ha in the first year to 65 q/ha in the final year. The technology index also showed a declining trend from 25.00% to 19.40%, indicating increasing feasibility and acceptability of the improved package of practices among farmers.
The findings conclude that FLDs play a vital role in accelerating adoption of improved agricultural technologies, reducing yield gaps, and enhancing farmers’ income. The demonstrated practices have strong potential for large-scale dissemination across Manipur and similar agro-ecologies.
