Abstract
The high yielding variety Ranjit is the most popular rice variety in Sivasagar district as is the case for the entire state of Assam. However, its productivity in Sivasagar district is still quite below its potential, primarily because of non-adoption of the management practices recommended to the farmers. To demonstrate the effect of latest technologies on the productivity, the KVK, Sivasagar carried out altogether 24 Front Line Demonstrations (FLD) on the variety with application of Zinc sulphate @ 25kg/ha + NPK @ 60:20:40 kg/ha (recommended dose of fertilizer for paddy in Assam) covering an area of 12 ha of farmers field in five different villages namely Belimukhia, Hulalgaon, Phoolpanichiga, Namti, Bhekurichapori during the year 2018 - 2020. The results recorded in these demonstrations were compared with those under the farmers' local practice. The results revealed that application of Zinc sulphate along with RDF in paddy enhanced the average yield to 53.17 q/ha in FLD plots as compared to 32.17 q/ha recorded under farmer's own practice. The percent increase in yield recorded 33.88%. the extension gap was recorded 21 q/ha whereas technology gap and technology index were observed 6.83 q/ha and 11.37 % respectively. The results revealed that the FLD was effective in changing attitude, knowledge and adoption of improved technologies of paddy cultivation and ultimately in obtaining sustainable income from paddy cultivation in Sivasagar district of Assam.
