Psoralea corylifolia plant is reputed for its psoralen content, largely used in psoriasis and certain immune diseases. To assess the possibility of its introduction and cultivation as a specialized crop, yield trials with different levels of nitrophos fertilizer (20:20 NP) on the seed yield were conducted for three consecutive years at Medicinal Plant Farm of Pakistan Forest Institute, Peshawar. The plant has successfully acclimatized under climatic and edephic conditions; gave better growth and higher seed yield by the application of split doses of 200 kg nitrophos/ha.
