Apple (Malus Domestica) is one of the most important horticultural produce and illustrious worldwide for its health benefits. One of the major apple producing zones in the north India is Jammu and Kashmir and major portion of the state is economically dependent on this horticultural industry. The present study is an attempt to find past trends of apple in Jammu and Kashmir using parametric, nonparametric and semi-parametric regression methods. The performance of each method is compared using higher values of R2 and lower values of residual criteria. It is found that the nonparametric/semi-parametric regression comes out to be good fit for trends in apple production in comparison to the parametric regression. Even semi-parametric spline regression is selected as the best fitted model for trend analysis. It is inferred that the area under apple cultivation in Jammu and Kashmir is increasing from 1974-2015 and the productivity has also shown an increasing trend except for some years where the trend is found declining. The study advocates for researchers technological breakthrough in apple production in Jammu and Kashmir.
