Rate of litter production & decomposition in a forest can be considered as an estimate of net production of plant community. Sal leaf, litter decomposition of litter fall in forest in Deohana, Pooranpur range of Pilibhit District. Season wise succession changes in litter fall were determined for four main seasons of the year namely, March-May, June-August, September-November and December-February. The physiological properties of soil for two different types of forests (A. pure Shorea robusta B. Mixed Shorea robusta) were analyzed Litter fall and leaf litter decomposition were studied in Deohana forest, North parts of Pilibhit district, stand dominated forest by Shakhu leaf (Shorea robusta) common Names of Shakhu. There is considerable amount of litter fall annually in tropical dry deciduous forests of total litter fall 78% was contributed by leaves. The trend of litter fall decomposition of different components was in the order: Leaves with petiole > Twig > Floral parts + seeds/ Fruits > Bark. Total annual litter fall was 980gm-2 of which there has been a seasonal variation in litter production. Shorea robusta produced 785gm-2 the total litter fall was found to be maximum in spring and minimum in rainy seasons. Annually nutrients in the form of Sal leaf litter and biomass from the larger number of Sal trees and their saplings 87.7% of Sal tree leaf litter was decomposed. The higher levels of soil nutrients in the forest were due partly to reduction in the loss of top soil and partly to the increased supply maximum rate of leaf litter decomposition was observed in spring season.
