Representative eight-year old trees of Melia azedarach planted in single line (2 m apart) on farm boundary were felled for estimation of aerial biomass production. The trees were grouped into three diameter classes. Maximum number of trees were recorded in the diameter range of > 22 cm. The trees contributed a total biomass production of 21.1 t/ha of which 66, 24 & 10 per cent were contributed by minor timber, firewood and fodder, respectively. Considering the overall phytomass production, the additional productivity in a rainfed farm was estimated to be 2.64 t/ha/year on a rotation of eight years. Biomass prediction equations based on regression analysis with D2, dbh and D2H were developed. The relationship of bole and total aerial biomass was found to be strong with all the predictor variables whereas relationship of foliage was strong with D2 and D2H only.- Biomass Prediction in Leucaena leucocephala

Study has been carried out on prediction of biomass in Leucaena leucocephala (Lam.) de wit, Data pertaining to biomass/growth attributes on one hundred plants ranging from 3.5 to 7.5 year growth have been taken by actua1 felling of trees. Optimum prediction equations were decided on the basis of Coefficient of determination (r3) along with significance of regression with its minimum standard error. It has obtained from the data presented, that variation in the biomass/growth had increasing trend upto 6.5 year and decline afterwards. It was found that dbh provides the optimum prediction of biomass with good precision. Biomass prediction table, according to different dbh growth was also computed.- Statistical Analysis of Growth and Biomass Production Data in some Multipurpose Trees

Statistical analysis of data pertaining to three fuel-cum-fodder trees viz; Acacia tortilis, Hardwickia binata and Leucaena leucocephala planted under agro-silvipasture and farm forestry experiments have been discussed, in the light of normality of data. 54, 39 and 50 samples of size 20 each belonging to these tree species have been chosen for deciding the criterion of transformation function. Sample size with desired variation in mean above-ground biomass in tree have also been discussed. It has been found that logarithmic transformation is most suitable for Acacia tortilis and Hardwickia binata while square ischolar_main function for Leucaena leucocephala. Sample size with desired 10% apartness from mean were found as 95-100% in case of L. leucocephala, 68% in A. tonilis and 15% in H. binata of available plants.- Fuel and Forage Production from Leucaena leucocephala under Farm Forestry

Fuel and forage production from farm forestry plantation of Leucaena feucocephala at 4 and 5 years of age in the second rotation indicated double production compared to the first one. The mean annual increment showed a higher rate at 5 years of harvest compared to the 4 year one. The plant type gave a highly variable performance due to which there was wide difference between the two durations of harvest. Thus, upto 27.38 t/row km of firewood and 2.58 t/row km of dry forage could be produced in this system adding an additional resource to the rural set up.- Production of Aerial Biomass in Leucaena leucocephala (lam.)

Aerial biomass and coppice shoot growth observations of Leucaeua leucocephala, harvested at 3 and 4 years of age under farm forestry conditions have been presented in this paper. The mean annual increments after 3 and 4 years study show rising trend with maximum increment between the 3rd and 4th year. Under this system it can be possible to harvest fuel wood and forage upto 11.0 tons and 1.0 t/raw km respectively of dry matter on the 4th year. The coppice shoot growth in 1.5 years was found to be equal to the original 3 years growth of the trees thus indicating high coppice growth polentiality and forage yield in this plant.- Fodder Trees and their Importance in India

In this paper the problem of sustenance of huge livestock population vis-a-vis this paucity of green nutritious fodder has been emphasized. The importance of fodder tree in suppling highly nutritious green fodder especially during the lean period and their specific role in the flood affected areas, arid and semi-arid region and also in hilly areas has been illustrated. Plantation of fodder tree their lopping management, nutritive value have been described.- Studies on the Vegetation of Bundelkhand Forest Division, Jhansi-herbaceous Vegetation
