42 EXPERIMENT STATION BULLETIN 351 



Seven different inter-specific hybrids have been obtained from crosses 

 made with species of Kalanchoe, a genus of succulent plants. Only one 

 of these hybrids has been self-fertile so that a second generation could be 

 grown. However, some of the hybrids are very promising as house 

 plants, since they are very easily grown in the home.

Propagation of Lily-of-the-Valley 



The first plantings of lily-of-the-valley were made in April 1942 

 when one thousand each of two German strains and one thousand of a lo- 

 cal strain were planted in alternating rows. In September 1942, plantings 

 were made of two additional local strains and fertilizer applications were 

 made to four sections of the field as follows: - 20 - 20 + manure, ma- 

 nure alone, 5 - 8 - 7 + manure, and 5-8-7 alone. 



Some pips were dug and stored for forcing trials during the summer 

 of 1943. Considerable attention must be giv^en to grading, storage and 

 forcing of lily-of-the-valley. Also the method of field culture now be- 

 ing used will prove expensive because of weed control. Another year 

 plantings will be made under deciduous woods to obtain comparatively 

 weed-free conditions of growth. 



Results of fertilizer treatments and comparative forcing quality of 

 the various strains will be available at the end of 1943.

Pasture Management Studies 



There appears to be no long time difference in the effectiveness of 

 brush control on pastures \\hether brush is burned, cut, or pulled. Since 

 burning requires much less time per acre than hand cutting, or pulling, 

 this should be the accepted method. If the land is not too rocky or too 

 rough to prevent the use of a power brush mower, this method of brush 

 removal should be the most efficient. On many of our good soil pastures, 

 however, hand cutting is the most practical method due to the ponderance 

 of rocks and boulders. 



Two kinds of brush are not easily controlled: low bush blueberry 

 and sheep laurel. The eradication of sweet fern responds readily to cut- 

 ting and new plants are easily pulled. 



About 60 hours per acre were required for burning, 80 hours for 

 cutting, and 100 hours for pulling. At the end of five years, an hour per 

 acre should be sufficient to cut or pull brush renewal. The amount of 

 time involved for reclaiming pastures, even by the cheapest method, 

 makes it necessary to select only those areas where the soil is such that 

 good pasture will be obtained after brush is removed. 



Results indicate that continued attention is important. Both the 

 annual removal of new brush and sound fertilization are practical and 

 economical in order to maintain adequate growth of good pasture vege- 

 tation. '
