    Cashew - based farming system
    (2007-02-08) Mandal, R.C.; Yadukumar, N.; Mohan, E.
    With a view to find out suitable intercrops in the early stages of cashew plantation (for first 5 years), an attempt has been made at National Research Centre for cashew, puttur to grow cashew as main crop and pigeonpea, tapioca (annuals); pineapple, papaya (biennials) and tree species like Casuarina, Acacia, Subabul (Perennials) as inter and mixed-crops and these are being compared with a cover crop {Mucwia sp.) and a control (without any inter crop). Preliminary studies indicated that both the food crops as intercrop can be successfully grown in the laterite undulating land. Growth of fruit crops and tree species were found to be very satisfactory under rainfed condition. It is thus possible to utilize the wider interspace (spacing 8m x 8m) profitably during the pay-back period of cashew and thereby to get additional income which has been illustrated in this paper.

    Effect of plant density on photosynthesis in cashew
    (2007-02-08) Balasimha, D.; Yadukumar, N.
    The net photosynthesis and related parameters were studied in cashew trees (Anacardium occidentale L.) grown at five plant densities. There was significantly higher photosynthesis and transpiration in wider spaced trees parallel with higher irradiances. Stomatal conductance (g) did not show significant differences between the plant densities treatments. In cashew, plant density of 625 ha1 (4x4 m) may be a threshold level for optimising productivity.

    Performance of four Varieties of Black Pepper (Piper Nigrum L.) as Mixed Crop with Arecanut (Areca Catechu L.) Under Different Planting Densities
    (2007-02) Abdul Khader, K.B.; Nair, M.G.K.; Yadukumar, N.
    A study was conducted to Investigate the performance of four varieties of pepper as a mixed crop in arecanut garden with six planting densities. The results revealed that in arecanut garden with a recommended spacing of 2.7 x 2.7 m, 43 per cent of sunlight is available to other component crops. Pepper as a mixed crop did not influence the yield of arecanut and Karimunda followed by Panniyur-I were found to be suitable pepper varieties in arecanut garden. The highest yield of pepperwas observed with a spacing of 1.8 x 2.7m with Karimunda variety. The results also indicated that pepper is a profitable mixed crop in arecanut garden.
