Abstract

To study the root -growth behaviour of crops for devising environmentally sound strategies for efficient input-use
and high yields, a rhizotron facility was established at Ludhiana tor in-situ monitoring of root-growth dynamics. It
consists of 16 rhizotron chambers and was developed by using indigenous design and materials, and is the tirst of its kind in India. Each rhizotron cell hasI. 2 m wide and 2.4 m deep viewing-window, specifically designed to study root growth, nutrient and water dynamics in tield crops raised on deep alluvial soils. Besides root-growth monitoring, it has a provision of metered water supply, soil-water measurement and manually operated mobile rain shelter and hence can be used as lysimeter.
