 Biedermann's Zentralbl. Agrikulturchem. 47: 250-258. 1918. — The amount of oil produced 

 by the sunflower was found to be low when compared with that obtained from other crops, as 

 rape and poppy. The author apparently does not advise cultivation of the sunflower for 

 oil, either in small plots or on a large scale, for the plot experimented on barely paid expenses.

 — The author obtained 20,000 pounds more per hectare by using large potato tubers for seed than 

 when he used small ones. Large tubers as seed are especially recommended for poor soil. 

 Good results are secured if small seed potatoes are spaced close together in the rows while 

 large ones are spaced farther apart (2 ft.). — F. M. Schertz.

 Biedermann's Zentralbl. Agrikulturchem. 47: 325-333. 1918. — The author conducted field 

 experiments on sandy soil and on loam. His results from loam soil are as follows: Whole 

 potatoes of 50 grams weight under unfavorable weather and bad nutrient relations gave less 

 yield than whole potatoes of 75 grams weight. Stronger fertilizing or better weather was 

 able, to a large extent, to make the difference in yield not so great. Under the favorable 

 conditions of the year 1917 the small (50 grams) and the cut potatoes (00 grams) yielded from 

 12 to 18 per cent less than the larger whole potatoes (75 grams). Experiments on sandy 

 soil were conducted according to the following scheme: (1) Small potatoes of 50 grams 

 weight. (2) Large potatoes of 70 grams weight. (3) Half potatoes of 00 grams weight. (4) 

 Alternately a large and a small potato. (5) Alternately a large, a small and a half potato. 

 The tubers were planted according to three schemes as to spacing. (1) 60 by 49.0 cm. apart. 

 (2) 60 by 55.5 cm. apart. (3) 00 by 59.5 cm. apart. Three different mixtures of fertilizers 

 were used. (7) Potassium phosphate without nitrogen. (2) Potassium phosphate with 40.5 

 grams of nitrogen as ammonia. (3) Same as 2, only using 77.5 grams of nitrogen as ammonia. 

 Conclusions are: (1) The half potatoes gave a considerably inferior yield than the whole 

 potatoes. (2) The increased nitrogen fertilizer gave an increase in the potato yield. (3) 

 50-gram potatoes gave a yield slightly superior to 70-gram potatoes. (4) The greater yield 

 was obtained when large and small potal ies were planted alternately. The smallest yield 

 was obtained when the potatoes were cut. Spacing the plants 00 by 49.0 cm. gave a yield 

 of 502 hundredweight per hectare, 60 by 55.5 cm. yielded 512 hundredweight, and 60 by 59.5 

 cm. yielded 520 hundredweight. Hence the wider spacings were progressively more produc- 

 tive— F. M. Schertz.
