Item Areca based high density multispecies cropping system in coastal Karnataka(2007-02-08) Ravi Bhat; Reddy, V.M.; Khader, K.B.A.The studies on areca based high density multi species cropping system (HDMSCS) were conducted at Central Plantation Crops Research Institute, Regional Station, Vittal for 10 years from 1983-84 to 1992-93.The results revealed that in a HDMSCS, intercropping did not affect the arecanut yield negatively. Banana is economical in the initial years. Pepper is good inter-crop during the early years and needs replanting after 5 to 6 years in disease prone areas. Cocoa grows well with areca and gives good returns.Item Coconut and arecanut based high density multispecies cropping systems(2007-02-08) Bavappa, K.V.A.; Kailasam, C.; Khader, K.B.A.; Biddappa, C.C.; Khan, H.H.; Kasthuri Bai, K.V.; Ramadasan, A.; Sundararaju, P.; Bopaiah, B.M.; George V. Thomas; Misra, L.P.; Balasimha, D.; Bhat, N.T.; Shama Bhat, K.High density multispecies cropping models were laid out one each in coconut and arecanut plantations during 1983. Data on various aspects of the system behaviour showed that the yield of coconut and arecanut increased to the extent of 176% and 12S% respectively in the two systems. The possibility of getting additional yields due to cropping system approach was, evident. There was no marked yield difference of the crops in the full, two-third and one-third levels of fertilizers applied though depletion in N and Mg balance was indicated. The air space utilisation was 31% in coconut while it was 63% in the arecanut system. The biomass production of the two systems showed that there was substantial increase in coconut biomass while the biomass of other crops remained more or less the same. In general, there was build-up of P and K nutrients in the systems. Under the arecanut system N also showed increased balance. There was improved microbial activity in the systems. No serious pest and disease management problems were indicated due to the high density cropping system approach. A number of crop varieties and hybrids tolerant/resistant to the nematode pathogen could be identified. The interaction of various, factors for exploiting higher levels of productivity through a system approach and the need for predicting crop choices based on data and crop performance are discussed in the paper.Item Coconut and arecanut based high density multispecies cropping systems(1986-12) Bavappa, K.V.A.; Kailasam, C.; Khader, K.B.A.; Biddappa, C.C.; Khan, N.H.; Kasthuri Bai, K.V.; Ramadasan, A.; Sundararaju, P.; Bopaiah, B.M.; George V.

Mangala had significantly less set volume and maximum yield compared to all other varieties, without any difference in other growth or photosynthetic characteristics. Mangalas early bearing and high yield seemed to have resulted in less stem volume due to partitioning of more photosynthates to flowering and fruiting during the early years of growth.Item Plant competition cocoa-areca mixed cropping system(1992) Jose, C.T.; Khader, K.B.A.; Jacob MathewItem Scheduling Irrigation for Arecanut with Pan-Evaporimeter(1985) Yadukumar, N.; Khader, K.B.A.; Shama Bhat, K.
