IntroStrawberry (Fragaria x annanasa Dutch) has been grown commercially in various parts of the world for many years but in India it was only introduced in the early 1960’s (Sharma and Sharma, 2004) and it has now accli- matized well in different parts of India. This is essentially a temperate fruit crop hence its expansion in the Kashmir valley has been gaining popularity in the last decade. It is not only consumed as fresh fruit but is also used in pro- cessed foods such as jam, ice cream, biscuits and so on. The demand for strawberry fruits for domestic as well as export markets has been increasing steadily. temperatures are important, strawberry requires an optimum daytime temperature of 22°C and nighttime temperature of 13°C for maximum growth and yield (Shoemaker, 1977). Growing strawber- ries under polyhouse decreases the dependence of fruit quality on climate and soil conditions. Such cultivation system also enables better water, light and temperature control to a certain extent.
