  The results of a 3³ factorial experiment conducted at two locations with two high yielding clones (RRII 105 and PB 235) of Hevea brasiliensis are discussed in relation to growth and soil fertility characteristics. Application of N, P₂O₅ and K₂O at the rate of 30, 30 and 20 kg per ha respectively resulted in significant increase in girth and girth increment in both the clones. Clone PB 235 responded to the application of fertilizers during the entire period of immaturity, whereas RRII 105 responded only during the early immaturity period.

- - Abstract
  - Keywords
  Rubber wood from three cultivars (Gl 1, MK 3/2 and GG 2) of Hevea brasiliensis from plantations in southern Kerala, India, established in 1963 was evaluated for physical and anatomical properties. Results from this preliminary study indicate that there are possible differences among cultivars in basic density and tension wood.

- EFFECTS AND ECONOMIC VIABILITY OF INTERCROPPING COOKING BANANA WITH RUBBER IN NIGERIAResearch Articles

- - Abstract
  - Keywords
  Studies on the effects of intercropping cooking banana cv cadaba on the growth of rubber (Hevea brasiliensis) saplings were carried out from 1993 to 1996 at Akwete Nigeria. Banana was intercropped 18 months after planting rubber and four spacings were incorporated. No adverse effect of intercropping was noticed on the growth of Hevea saplings. The rubber + 4x2 m and 2x2 m spacings for cooking banana, had the highest girth increase rate with 0.23 and 0.22 cm per month. The highest mean cadaba bunch yield and production of suckers, of 9.0 t per ha and 3833 suckers per annum respectively, were observed in the rubber + 2x2 m spacing for cooking banana. This treatment also gave net present value of $ 1321.51, a profitability index of 2.59 and internal rate of return of 50 per cent. The 2x2 m banana spacing was the only treatment that had the capacity to optimize returns from the land and ensure cash flow into the rubber based farming business thereby improving the liquidity position of the system during the long gestation period.
