Climate change following global warming has necessitated changing the pattern of cultivation in agricultural ecosystems. However, farmers are reluctant to change the pattern of cultivation problems due to lack of knowledge of new crop cultivation. Expanding the cultivation of new and expensive plants will encouragement farmers to accept the changing pattern of cultivation. Physallis(physalisperuvna L.) is a suitable plant for changing the pattern of cultivation. Seed expensive and non-uniformity of emergence is one of the problems of this plant. For this purpose, a factorial experiment in a completely randomized design was conducted with 4 replications in laboratory and greenhouse conditions. Treatments included potassium nitrate at 4 levels, which was added to PA organic coatings. The results showed that the application of potassium nitrate with PA coating significantly increased the percentage of 3th day emergence, emergence rate, seedling length and relative growth rate of shoot length. Application of improved organic coatings reduced seedling losses and increased strong transplants. On the other hand, the increase in shoot growth rate reduced the duration of seedling production. Strong seedling production will greatly increase the chance of transplantingto filed condition.
