Abstract:
A study has been conducted to analyse the economic feasibility of betelvine as an intercrop in the rubber holding of Mavelikkara taluk .
Only five units having betelvine as intercrop could be identified in this area. One hundred other holding 20 each of betelvine as pure crop, plantain as intercrop, plantain as pure crop having covercrop and without any intercrop were also selected for the study .
The study revealed that only a small portion of the holding was occupied by the betelvine, when it was treated as an intercrop. The cost of cultivation was found to be very high when compared with other cash crops. This might be the reason for limiting the cultivation to a small portion. This was confirmed by the fact that betelvine as pure crop was also limited in extent.
The benefit cost analysis of the above crops revealed that betelvine cultivation was highly profitable with a benefit cost ratio of 2.51 in the intercropped area and was significantly higher than that for plantain which is the other common intercrop. The soil analysis data showed that betelvine absorbed lesser nutrients than plantain .
The rubber plants of betelvine intercropped area showed vigorous growth than other intercrops which was due to the regular irrigation and fortnightly application of organic manure to the betelvine.
Though the cost of cultivation was very high for betelvine , it could be recommended as an intercrop in the rubber holdings where there is availability of water throughout the year since it ensures substantial weekly income for the grower and his family.
Though betelvine could be treated as a perennial crop, the farmers choosing it as an intercrop in rubber holdings will have to sacrifice the same by the fourth year when the rubber canopy closes to the full extent. Hence, we can suggest betelvine as an intercrop in rubber holdings only if land is too scare for its monoculture.
