Abstract

With a view to raise healthy plants for in time supply, a portable solar warmer-cum-nursery plant protector (SWNPP) has been developed. Head loss estimates and the extent of total solar impact at two different locations in the Himalayas have been worked out. Using commonly available materials a local village carpenter can very easily fabricate SWNPP unit. It can be installed by any un-skilled worker quickly right on the nursery bed as and when needed. These units have got heavy potential to be used in the temperate as well as sub-tropical zones of Himalayas experiencing sudden weather changes and where full-scale green houses for various reasons area generally not feasible.
