phosphorus level in the soil. For optimum conservation and utilization of rainwater, preferably half moon
shaped micro catchment technique can be accompanied for individual trees, it is carried out by providing mild
slope to the land on the upstream of planted seedling leading the rainwater to the roots of planted seedling
and making a crescent or half moon shaped bund on the downstream side of pit at a distance of 1m from the
stem of tree (Fig.1).At least one year old seedlings of the karanj trees are planted after onset of first monsoon
rains. After that the rooted slips of grasses containing 4-7 tillers are planted in 10 cm hole dug with the spade
at the onset of monsoon. The soil around the planted slip was made compacted with foot. Before planting of
rooted slips the grass clumps are cut at 7-10 cm from ground and thinned to prepare rooted slips containing
4-7 tillers. Survival and growth of the planted vegetation is influenced by choice of species depending on
edaphic factors, timely planting and management aspects in the initial stages. In these areas experiencing high
biotic pressure on trees were profusely seen, it needs proper protection from browsing and trampling till they
are high enough to attain sufficient height to avoid browsing.Grass production increases from the 2 year
nd
onwards. Grass cutting allowed two times per year. About 1/3 area is to be re-sodded or re-sown with same

grass species at the end of 5 year for sustained grass production from system. After 7 grass yield declines

Result
Pongamia pinnata based silvipasture system was suitable for medium and deep ravine lands. Though
silvipastoral system can be developed in all kinds of lands, but moisture management is to be important
measure particularly for rain water utilization and natural resource conservation in ravine lands. Eight years
of evaluation indicated that, Pongamia pinnata along with half moon shaped micro catchments impacts on
higher growth which resulted as height (6.12m), collar diameter (22.38 cm), DBH (10.50cm) and crown
spread (45.71m ) compare to other treatments. Among three TBO species evaluated on ravine land, highest
