In 1986-1988 in the Experimental Farm of the Lithuanian Institute of Agriculture farm-technological trials were conducted to investigate the intensive technology of winter wheat cultivation with the objective to obtain grain yield of 55-60 dt/ha and more. Three technologies were tested: conventional (up to 1985) and two new ones-intensive with permanent tramlines on the sowing and intensive wi ...

Field experiments were carried out over period 1992-1994 at the Lithuanian Institute of Agriculture in Dotnuva with a view to ascertaining the most efficient herbicide against weeds in emerged sugar beets and to extend the herbicide action by using herbicide mixtures. The experimental results showed that all then herbicides tested gave a very similar weed contro of 40,3-54,2 until the leaves c ...

In 1988 forest monitoring network (grid size 4x4 km) including more than 960 permanent observation plots (POP) and more than 23 thou. sample trees was established in Lithuania. In 1992-1995 the number of POP and sample trees have been reduced. The mean defoliation of all species (22-24) has not been increasing during the past 2-3 years, whereas the significant defoliation increase (t-test has ...

Here produced a principle of building an analytical model for definition for vibroacoustic capacity on side surfaces of crankshaft's carter blocks in air cooled tractors engines. The experimental testing results concerned with distribution of vibrational levels according to separate zones and characteristical points on side surfaces of engines' carter were given. There are comparised results o ...

In the article further continued investigation mathematical model of the carters side walls vibrations of tractors air cooled engines. There is shown, that greatest amplitudes of vibrations are in the middle of the bottom of carter's side wall. By introducing additional connections it is possible significantly decrease the amplitude of the vibrations. Experimentally established the stiffening ...

The effect of harrowing and the efficiency of herbicides Stomp, Basargan M and MCPA on weediness and grain yield of peas were investigated. Harrowing only at 3-5 leaves stage resulted in the increase of grain yield by 0.17 t/ha, or by 4.8 and in the reduction of weeds and air-dry mass by 25.9 and by 9.7 relatively. By combining harrowing before pea emergence with the application of 2 l/ha of S ...
