Effect of different spacing and fertilizer levels on yield parameters of mungbean under guava based agri-horti system

A field experiment was conducted during kharif season of 2012–13 to find out suitable management practice to manage agri-horti system under Psidium guajava L. based agroforestry system. Suitability of the method was assessed based on yield of mungbean. The yield attributes i.e. pod/plant, pod length, number of seeds/pod, seed yield, stover yield, biological yield and harvest index were significantly influenced with distance and RDF levels. The seed yield of mungbean was significantly higher due to tree management practices imposed to Psidium guajava L. Seed yield as affected by distance from tree was found significant in D2 (2.0 m away from tree 748 kg/ha) recorded significantly higher seed yield than D1 (1.25 m away from tree 629 kg/ha) in mungbean. Seed yield as affected by RDF levels were also found significant. No significant difference recorded in between F3 (75% RDF) and F4 (125% RDF) and they were found significantly superior than remaining RDF levels. Lowest seed yield recorded in F1 (50% RDF) level. Interaction between distance from tree and RDF level was found significant. The seed yield of mungbean significantly higher with the combination of 2.0 m away from tree and 100% RDF level.
