The present study entitled "Evaluation of pheromone traps for the management of pod borer, Helicoverpa armigera (Hubner) in Redgram [Cajanus cajan (L.) Millsp.] ecosystem" was carried out to study the influence of trap height on catches of H. armigera in redgram ecosystem during kharif 2017 at experimental farm of NPRC, Vamban and farmer's field at Vadakaddu.Funnel traps were more effective compared to delta traps and green funnel traps placed at the level of crop canopy (96.0 moths / 5 traps) and one foot below the crop canopy (94.8 moths / 5 traps) performed well compared to traps placed at two feet below the crop canopy (77.1 moths / 5 traps), one foot above the crop canopy (66.6 moths / 5 traps) and two feet above the crop canopy (58.9 moths / 5 traps).
Aims: India is the largest importer, producer, and consumer of pulses in the world. In order to protect indigenous pulse production, India must not only produce enough pulses, but also remain competitive. It was recommended that extension agencies involved in the transfer and application of agricultural technologies to farmers' fields prioritise organising frontline demonstrations on a cluster basis to maximize pulse crop productivity.
Study Design: Expost-facto study.
Place and Duration of Study: The study was conducted among farmers from Pudukkottai district which covered under KVK, Vamban. The demonstration period was 2016 – 2019.
Methodology: By simple random sampling technique, 30 farmers were selected and VBN 6 variety was demonstrated in the area of 6 ha.
Results: The maximum yield was 9.74 qtl/ha and average yield was 9.48 qtl/ha. The yield gap minimized was 0.2%. The B.C ratio was 4.06 which indicated the profit level.
Conclusion: The study concluded that VBN 6 in recommended practice proved beneficial in respect of yield and economics of blackgram.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
