TAILIEUCHUNG - Feasibility of rubber+tea intercropping during immature phase of rubber

An experiment of rubber plants intercropped with tea was conducted at the Regional Experiment Station, Nagrakata, Jalpaiguri district of West Bengal to see the feasibility of growing tea as intercrop with rubber in Dooars area of north Bengal. It can be concluded that tea can successfully be grown as beneficial intercrop in between the inter-row spaces of rubber by changing in the crop geometry during immature phase of rubber with additional benefit of less attack of red spider mite to tea crop/leaf. Growth (girth) of rubber was significantly superior under intercropped treatments (T3 & T5) than pure rubber stand (T1) while girth of tea plants was found at par in all the treatments. Green tea leaf yield at 100% population of tea under pure tea stand was found significantly superior than the green tea leaf yields in all the intercropped treatments but at 100 % plant population of tea, all treatments were found equally good with pure tea stand. Remunerative index values of different intercropping systems varied from to . Infestation by red spider mite Oligonychus coffeae Nietner) was found significantly lower in all intercropped treatments than pure tea stand of tea. | Feasibility of rubber+tea intercropping during immature phase of rubber
