Abstract:

A field experiment was conducted in ‘A-B’ Block Farm of BCKV during rabi seasons of two consecutive years 2017-18 and 2018-19 to study the effect of various plant morphological characters against population fluctuation of major pests occurring on different varieties of field pea (Pisum sativum L.).Aphid population varied from 0.26 per plant to 2.08 per plant in first year and the range was 1.23 to 3.99 per plant during second year, while the larval population of gram pod borer varied from 0.24 to 1.57 per plant in first year and from 0.01 to 0.38 per plant in second year. Pod damaged ranged from 7.20 to 31.17 per cent in first year and the range was 0.29 to 21.87 per cent in second year. Gram pod borer population showed significant and positive correlation with plant height and number of seeds per pod among different plant morphological parameters during both seasons. However, only number of number of primary branches per plant showed significant and positive correlation with aphid infestation. Multiple step wise linear regression study revealed that plant height was the sole influencing factor over the intensity of larval population of gram pod borer and number of primary branches per plant was the sole influencing factor over the infestation of aphid during both seasons.
