Determinants of adoption and constraints faced by farmers using nano urea plus in soybean production in Haveri district of Karnataka

Abstract

Soybean (Glycine max L.) is a major oilseed crop that contributes significantly to farmers’ income and plays avital role in India’s agricultural economy. In the year 2024-25, the study was undertaken to investigate the factors influencingthe adoption of nano urea plus and to identify the major constraints faced by sample farmers using nano urea plus andconventional urea in Haveri district of Karnataka. The primary data was collected from soybean growers. The results of thestudy revealed that the age had a negative coefficient value (-0.6012) which was statistically significant at 5 per cent levelof probability. The odds ratio analysis indicated that subsidy availability increased the likelihood of adoption by 5.53times. The availability of subsidies had the highest marginal effect at 0.5582 which showed that access to subsidiesincreased the probability of adoption by 55.82 per cent. The results of Garrett’s ranking techniques analysis showed thatthe most severe constraint identified was difficulty in the requirement of equipment for application of nano urea plus whichhas ranked first with the highest Garrett mean score of 64.50.
