ROLE OF N, P & K CONTENTS IN RESISTANCE AGAINST ASCOCHYTA BLIGHT OF LENTIL (LENS CULINARIS MEDIK)
Abstract
Nitrogen and phosphorus contents of un-inoculated plants of lentil lines included in susceptible group were higher than those of the resistant one whereas, potassium, contents were more in the un-inoculated lines of resistant as compared with the susceptible group. Upon inoculation with Ascochyta lentis, the nitrogen and potassium contents, increased invariably in both the resistant and susceptible group of lentil lines. On the other hand, phosphorus contents increased in inoculated lentil lines of the susceptible group but decreased in those of the resistant group. In general, it was found that the plants lower in nitrogen and phosphorus were resistant to lentil blight while those with higher nitrogen and phosphorus were susceptible to lentil blight disease caused by Ascochyta lentis.
