Paraserianthes falcataria - Southeast Asia’s Growth Champion By whatever common or scientific names it is known‚ Paraserianthes falcataria (L.) Nielsen is a valuable multipurpose tree for the humid tropics. One of the fastest growing of all tree species‚ it is used for pulp and other wood products‚ fuelwood‚ ornamental plantings and shade for coffee‚ tea and cattle. Potential uses for which it is being tested include alley farming and intercropping in forest plantations. BOTANY: "Falcataria"

HYDROPONICS Hydroponics is a subset of hydroculture and is a method of growing plants using mineral nutrient solutions‚ in water‚ without soil. Terrestrial plants may be grown with their roots in the mineral nutrient solution only or in an inert medium‚ such as perlite‚gravel ‚mineral wool‚expanded clayor coconut husk . Some of the reasons why hydroponics is being adapted around the world for food production are the following: No soil is needed for hydroponics The water stays in the

ONION PRODUCTION IN A GREENHOUSE GREENHOUSE TECHNOLOGY Greenhouse is a structure that allows controls of certain environmental parameters for purposes of providing optimum conditions for the growth of a targeted crop. The greenhouse production is a highly specialized and intensive form of agriculture as Compared to field crop agriculture. The greenhouse production is more suited to vegetables‚ flowers; fruit a can also be used as a nursery for all vegetable crops‚ because of their short life-span
