FIELD CROPS. 657 



The absolute weighl of the kernel, the proportion of hull, the composition of th< 

 endosperm, and the percentage oi large-sized grains did no1 appear to be characters 

 of regular transmission. The fineness of the hull was transmitted with much greatei 

 regularity and greater frequency than the proportion of the hull to the grain. Th< 

 product from the Beed samples varying in aitrogen-free extract Bhowed a marked 

 reduction in mealiness, bul in the case of the Bamples differing in protein content 

 mealiness largely increased. In every instance excepl one the difference in the Bize 

 of the kernels in the Beed Bamples was greatly reduced in i he crops secured. 



The vitality and viability of all the barleys from the various sources were much 

 increased. Only 3 days were required for their complete sprouting and a type of 

 Manna barley produced on a calcareous soil gave LOO per cenl in vitality and 

 viability when :> years old. 



Varieties of barley, E. S. Beaven ( Reprinted from Jour. Fed. lasts. Brewing, 8 

 [1902), No. 5, pp. 548 600, ph. 7).— This paper outlines the classification of the 

 different types of barley and discusses the differences in their Btructure. 



Experimental work with the crop, largelj with reference to its malting quality, is 

 reviewed and a list of varieties, together with data secured on the Warminster plats 

 for several year- past, is given in an appendix. Some of the work reviewed has been 

 previously noted I E. S. R., 9, p. 436). 



Experiments with corn, T. L. Lyon [Nebraska Sta. Bul. 91, pp. 85, figs. 14, map 

 1). — Cooperative tests of 14 varieties of corn were made in 6 sections of the State 

 varying in climatic conditions. 



The results of these experiments, now in progress for .'! years, indicate that in the 

 eastern part of the state Reid Yellow Dent. Bogue Yellow Dent, Nebraska White 

 Prize, Silver .Mine, Golden Cap, Golden Yellow, Golden Row, Mammoth White Pearl, 

 and Calico have been must satisfactory, while in the middle portion Learning, < !alico, 

 and Pride of the North, and in the western portion Pride of the North and Calico 

 were most promising. 



In studying the relation of size of ear to yield it was found that the heaviest yield- 

 ing varieties produced ears of medium size, the average weight per car of the 5 lead- 

 ing sorts being 0.705 lb., or considerably below the average weight per ear of all the 

 varieties. The corn raised in the central and western' part of the State produced 

 smaller ears than the same varieties grown in the eastern part. The number of ears 

 per bushel, as indicated by reports from experimenters, ranged from 93 to L32. 



In growing 1, 2, 8, or 4 stalks per hill it was found that the yield per acre increased 

 with the thickness of planting. The average weight of ears as well as the percent- 

 age of good ears decreased, as did also the number of ears per LOO plants and the 

 number of suckers per 1(H) plants. Under favorable conditions 3 stalks per hill in 

 row> 41 in. apart each way gave the Largesl yield of grain, but the conclusion drawn 

 is that the best rate of planting varies according to the soil and season, and that there- 

 fore in Nebraska the rate of planting in the eastern part of the State Bhould not be 

 less than 3 kernels per hill, while in the western part on the western edge of the 

 corn belt 2 stalks per hill are believed to be better than a larger Dumber. 



The size of ear showed a regular decrease as the rate of planting Increased. The 

 average ear from the planting containing 1 stalk per hill weighed 10.6 oz., while the 

 average ear of the planting with 5 stalks per hill weighed only 6,6 oz. The largest 

 number of good ears, amounting to 68 per cent, was obtained from the planting with 

 2 stalks per hill, [n 1904 the planting of 1 stalk per hill produced 1,392 lbs. of stover 

 per acre, the yield regularly increasing with the thickness in planting, and reaching 

 6,975 lbs. per acre with 5 stalks to a hill. The proportion of -rain to stover was 

 greatest with ."» stalks per hill, and this planting also produced the greatest total yield 

 in this season. 



The observations made in 1904 on the number of barren stalks as affected by plant- 

 ing showed that per cent of the stalks planted at the rate of 1 per hill were barren,
