Emasculation and bagging of flowers of Brassicaceae, Poaceae, Paplionaceae, Malvaceae and Linaceae (pollinating them manually and estimating fruit and seed set).

Euphorbiaceae : Euphorbia, Phyllanthus, Jatropha 18. Liliaccae : Asphodelus, Allium 19. Poaceae : Triticum / Hordeum 20. Determination of soil porosity and density by sand and pit method 21. Titrimetric estimation of total carbonates of soil samples. 22. Quantitative determination of soil organic matter by Walkley and Black’s rapid titration method. 23. Analysis of the herbaceous vegetation for frequency, density and abundance. 24. Study of the height spectrum of herbaceous vegetation by line transect method. 25. Effect of tree canopy on the distribution of herbaceous vegetation 26. Estimation of biomass of aerial parts of herbaceous plants (Fresh weight and dry weight). 27. Analyses of different water samples for pH, oxygen and carbon dioxide (titrimetric estimation), turbidity and temperature. 28. Field visit: Field visits to places of ecological/environmental interest. Students are required to submit a detailed report of the visit in the form of field diary in the Final practical examination for evaluation.
