Why is rubber growing not common in Uganda?

Low yields of rubber in Uganda seem to be mainly due to low temperatures, but the poor strains of rubber planted also appear to be partly responsible; for most of the trees have an erect branching habit very different from the whorled, spreading habit of many high- yielding clones in the East.

What climatic condition and ecology does rubber grow?

How can we increase rubber production?

Latex flow during tapping of the rubber plant Hevea brasilensis is the crucial parameter for rubber yield. The extent of latex flow depends on water circulation in the tissues surrounding the latex-producing cells. Water, and therefore latex flow, can be stimulated by ethylene or auxin treatment of the bark.

What type of climate is required for rubber?


Rubber is a tropical tree. It requires high temperature throughout the year – ranging between 20°-35°C or average monthly mean of 27°C. Less than 20°C temperature is detrimental. Similarly, rubber also requires heavy rainfall.

What kind of climate does rubber grow in?

Since rubber trees are tropical, they thrive in warmer, more humid climates and don’t handle cold, dry environments so well. They’re best kept between 60 and 78 degrees Fahrenheit, and you’ll want to avoid any major cold drafts or quick temperature drops.

In which soil rubber is grown?

Rubber is grown in literate or loamy soil, mostly in slope and undulated land or slightly high elaborated flat land where there is no possibility of water stagnation, and having well drainage facilities. Elevation: Rubber plants can be successfully grown up to the elevation of 450 metre from mean sea level.
