Grasses such as Blue panic, Guinea grass, Green panic, Rhodes grass, Signal grass, three cultivars of Buffel grass, two cultivars of Setaria and Legumes like Centro, Greenleaf desmodium, Highworth dolichos, Rongai dolichos, Archer dolichos, Tinaroo glycine, Siratro, Cook stylo, Schofield stylo, Endeavour stylo, Townsville stylo, Verano stylo were grown at six Silvicultural Research centres of Bangladesh to study their herbage production. Among grasses Signal grass, Guinea grass, Green panic and the cultivars of Setaria produced higher amount of herbage in comparison to other grasses. Legumes like Schofield stylo, Cook stylo, Endeavour stylo, Townsville stylo and Verano stylo produced higher yields of herbage in comparison to other legumes. These promising fodder grasses and legumes have important bearings on multiple land use in agriculture as well as in forestry.

Nominal 100 micron thick, 1 cm wide and 10 cm long radial/ longitudinal Pinus nigra microtome sections were dried and treated with dimethyl dichlorosilane in the vapour phase. The same experiment was repeated with previously water-leached specimens. The chlorosilane readily reacted with wood hydroxyl groups to form silyl cellulose. The silanation product was quite resistant to the effects of prolonged water leaching and is quite durable too.

2×2 cm radial-tangential 6 mm thick transverse wafer specimens of the same species were treated in both vapour and liquid phases. Water repelling effectiveness of the specimens were measured by time to half swell (Tj). ‘

Silanation by both vapour and liquid phases slows down the sorption process by over 70 times the normal process. The maximum equilibrium swelling is also brought down to 72.5% in the case of liquid phase and 75.0% in the liquid and vapour phase respectively. Conventional water repellents slow down the rate of water uptake but do not change the total sorption. This establishes the superiority of silanation over conventional water repellents in decreasing the maximum equilibrium swelling of wood in contact with moisture.

Diseases of 6 to 12 month old seedlings of Bokul, Debdaru, Jam, Kajubadam, Kumvi, Mohua, Sal and Shimul were recorded from Rasulpur Forest Nursery, Modhupur in 1974. Symptoms of the diseases have been briefly noted. Fungi were isolated from diseased seedlings, pathogenicity tests carried out in vitro on detached young leaves were the basis for ascertaining seven fungal and one algal pathogens. The extent of occurrences of the diseases was also recorded.
