e0“at Hyderabad to study the impact of crop -crop diversity on incidence of pod-borer [Helicoverpa armigera (Hubner)] on pigeonpea [Cajanus cajan (L.) Millsp]”
e3“The intercrops, viz sorghum (Sorghum bicolor L.), groundnut (Arachis hypogaea L.) and blackgram (Vigna mungo (L.) Hepper) reduced the pod damage by H. armigera, M. vitrata, and M. obtusa significantly”

Other claims from this paper (12)
- Observation The incidence of the major pod-borer Helicoverpa armigera in pigeonpea varied over time across cropping systems.
- Intervention effect Pigeonpea intercropped with groundnut reduced pod damage by H. armigera significantly.
- Intervention effect Pigeonpea intercropped with blackgram reduced pod damage by H. armigera significantly.
- Intervention effect Grain damage by lepidopteran borers was lower in pigeonpea + sorghum (l5.15%).
- Intervention effect Grain damage by lepidopteran borers was lower in pigeonpea + groundnut (22.26%).
- Intervention effect Grain damage by lepidopteran borers was lower in pigeonpea + blackgram (20.49%).
- Observation The effective intercropping systems gave the highest pigeonpea equivalent yields, in the range of 0.97-1.1 1 tonnes/ha.
- Observation The intercropping systems had a land equivalent ratio of 1.04-1.31.
- Observation The intercropping systems had an aggressivity of 1.03-1.49.
- Observation The intercropping systems had a competitive ratio of 1.77-1.97.
- Observation The intercropping systems had a relative crowding coefficient of 4.08 - 9.59.
- Intervention effect The intercropping systems were more profitable than sole pigeonpea.
