Abstract
A study on statistical analysis of socio-economic status of farmers on application of fertilizer was undertaken in selected districts of Karnataka i.e. Dharwad and Davangere. Compound growth rate analysis was used to know the growth of NPK consumption over a period of years. Binary logistic regression analysis was used to know the influence of socio-economic characteristics on application of recommended dose of fertilizer (RDF) under different crops. Multiple linear regression analysis was used to estimate the effect of NPK on yield.
The result revealed that NPK usage pattern in Dharwad district had negative growth rate (-5.77 %) over the years (2004-2015). Amongst all the three major nutrients, usage of phosphatic fertilizer showed significant negative growth (-7.70 %) followed by nitrogen (-3.9 5 %) and potassic fertilizer (-3.39 %). In Davangere district, it was observed that usage of nitrogenous (5.38 %) and phosphatic (3.07 %) fertilizers had positive growth rates. But, potassic fertilizer showed negative growth rate (-0.66 %).
The Binary logistic regression analysis revealed that experience of the farmer, size of land holding, type of the ownership, distance from shop to field, number of shops in the locality and annual income were found to be significantly influencing the adoption of RDF in different crops grown under the Dharwad district. Whereas in Davangere district the factors like age, experience, type of the family, size of land holding, farming expenditure, type of land ownership, distance from shop to field and number of shops were found to be significant factors.
Application of nitrogen played a significant role in increasing the yield of maize and Bt cotton, whereas application of phosphorous played a significant role in increasing the yield of soybean.
