Cherry (Prunus avium) is one of the important horticultural crops grown in Jammu and Kashmir and is packed with healthy nutrients and excellent antioxidants. Basically, cherries are native to Europe and Asia regions. Cherries are cultivated all over the world and the top 3 producers of cherry are Turkey, USA and Iran. India occupies as 26th producer in the list. In India, cherry commercial cultivation is carried in the states of Himachal Pradesh, Jammu and Kashmir and Uttar Pradesh due to suitable climate. The present study is an attempt to find past trends of cherry 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 cherry 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 cherry cultivation in Jammu and Kashmir is increasing from 1974-2017 and the productivity has also shown an increasing trend except for some recent years where the trend is found declining. The study advocates for researchers technological breakthrough in cherry production in Jammu and Kashmir.
