Punjab Agricultural University, Ludhiana, Punjab, India.https://krishikosh.egranth.ac.in/handle/1/5810185945The study was planned with the objectives to study the gain in knowledge of the respondents after watching informative videos, to ascertain the effectiveness of the videos related to paddy straw management, to study the satisfaction level of the farmers towards quality of videos on crop residue management. A multi-stage sampling procedure, a quasi- experiment design, a pre and post tests along with control group was applied. Four informative videos on crop residue management techniques, in-situ residue management, ex-situ residue management and fertilizer application were treatment in the study. Primary data was generated through structured interview schedule. The data analysis frequency, percentages, t-test, paired t-test and chi square were used. The results show that before treatments, there was non-significant difference in knowledge score between control and experimental group. However, after exposure to the videos a significant difference was observed in knowledge score from the residue management technologies videos. Majority of the respondents were found to be effective regarding different technical and scientific aspects of informative videos. Majority of the respondents were found to be satisfied with the videos in terms of language used and accuracy & credibility etc. The socio- personnel characteristics such as age, education, size of land holding were found to be significantly associated with satisfaction of respondents towards videos. Thus videos can be used as an effective medium of transferring agricultural information and enhancing knowledge of recommended technologies among the farming community.EnglishThesis
