Apple is the main cash crop of mainly four district of Himachal namely Shimla, Kinnaure, Kullu and Mandi having approximately Rs 5000 Cr economy p.a. The advanced research in horticulture has invented new varieties of apple that is growing in lower altitude of Himachal now but it is not significantly affecting the economy boost as an opportunity. Because Production of apple is totally depended on snowfall and it requires1000 chilling hours completion temperature at 40 c or below and regular monsoon and timely rainfall. Production of apple has increased with 121.44% with the increase in area under apple cultivation by 28.72% as compare to the production and area under apple cultivation of 1990’s decade with increase in productivity per hectare by 20.979 tonne per hectare in last decades of ten years which is average increase in productivity by 2.0979 tonne per hectare per year. There is fluctuation in apple production and productivity in year wise study of the data. Consistently negative and some sudden positive boosts in the fluctuation is a major cause of threat to the apple cultivation. The present research is decade wise and year wise changes in apple production.Key points: Production trend, productivity, growth in Cultivation, hypotheses testing chi square, Standard deviation, Fishers approximation chi square and Approximation rule for standard deviation from Range.
