Abstract
Effect of single superphosphate, urea, ammonium sulphate, potassium sulphate and animal dung on the formation of sporocarps inAzolla pinnata under the field conditions is studied. Of the 4 strains (India, Thailand, Vietnam and Bangladesh), the Bangladesh strain produced maximum number of sporocarps (mega+micro); the Vietnam strain developed maximum number of microsporocarps, but no megasporocarps. Animal dung at 1·0 t/ha enhances sporocarp formation. Phosphorus deficiency enhances formation of megasporocarps, while superphosphate decreases their number. Ammonium sulphate or urea at 30 kg N/ha increases the number of microsporocarps, while potassium sulphate increases their number irrespective of the rate of application.
