744 EXPERIMENT STATION RECORD. 



Oil the heavy and sandy marsh soils about 2 bu. of seed was sown per acre, and 

 on the moor and heath soils approximately 2.66 bu. The marsh soil was fer- 

 tilized with superphosphate, and tlie low moor, sphagnum moor, and heath soils 

 witli Thomas slag, kainit, slaked oyster-shell lime, and nitrate of soda. 



A heavy rain lodged the i)lats, and in this connection New Market, Beseler II, 

 Goldregen, and Probstei were the most resistant sorts. On the sandy marsh as 

 well as on the heath soil the crop lodged to a lesser extent than on the other 

 soil types. Injuries from thrips were greatest on the heath plat, but Mesdag 

 and Black President suffered little from this attack. Among the white varieties 

 (ioldregen was injured most and Probstei least. All sorts rii>ened latest on the 

 heavy marsh soil and earliest on the heath soil. 



The best results on the heavy marsh soil in the order of yield were secured 

 from (Joldregen, Probstei, and Beseler II. New Market gave the lowest yield of 

 straw and the highest yield of grain, while Black President was one of the 

 jioorest yielders. On the sandy or light marsh soil the rank was New Market, 

 (ioldregen, and Ligowo, while on the low moor soil Probstei stood first, followed 

 by Bigowo and New Market. On the sphagnum mooi- soil, which was quite 

 sandy, Probstei led m yield, followed by Beseler II. The yield of grain for all 

 varieties was low on the heath soil. 



The heaviest weight per hectoliter on all soils was given by Black President 

 and Goldregen. The different varieties, with the exception of Ligowo. showed 

 a maximum difference in hectoliter weight of about 4 kg. (about 4..57 lbs. per 

 bushel) on the different soil types. The highest average hectoliter weight was 

 secured on the sandy marsh and heath soils, and the lowest on the heavy marsh 

 and sphagnum moor soils. 



The investigations on the weight of the different parts of the plants and theiv 

 relation during different periods of growth seemed to have indicated that in 

 different varieties grown under like conditions the relation of the weights of 

 the different parts at maturity is constant. However, in the case of Probstei 

 oats this constancy was not established. 



A chemical study showed that relatively more organic nitrogen passes from 

 the leaves than from the stems. The nitrogen content of the different varieties 

 at maturity was practically tlie same for the stems, the leaves, and the heads. 

 In early growth the differences between the nitrogen content of the 6 varieties 

 was quite large, but from this period on there was a gradual approximation 

 until later the difference was practically wiped out. The results further showed 

 that the leaves and stems contributed a large part of their nitrogen content 

 toward the development of the grain. On the sandy marsh and on the heath 

 soil, the 2 types lowest in nitrogen, the development of the grain had drawn 

 largely upon the nitrogen content of the leaves. 



Beseler oats I, II, III, H. Dommes {Mitt. Landw. Iii>it. Breslau, 4 (1908), 

 X'). '/. pp- Jif>5-6'il), pis. 6. figs. 2. dgm. 1). — This is a monograph on these va- 

 rieties of oats. The history of their origin is related in detail, and the char- 

 acters of the embryos of the 3 varieties are described. In addition the principal 

 phases of growth with special reference to the morphological development of 

 the parts of the plant above ground are discussed, and the yielding capacities 

 of the varieties are compared. 



Beseler I is adapted to mountain climates and matures rather late. The 

 color of the straw and the grain is yellowish white. Beseler II may be profit- 

 ably grown on rich valley soils in a high state of cultivation. It ripens early, 

 stands up well, and is not injuriously influenced by heavy applications of nitrog- 

 enous fertilizers. The color of the straw and grain is a very clear white. 

 Beseler III is a pronounced yellow variety, leather ilrought resistant, and well 

 adapted to the continental climate of eastern Germany.
