 for the season of 1917-1919. Dept. Agric, Barbados, 1919. — Pages 4-19 deal with results of 

 manurial experiments chiefly. The results of these, however, are said to be inconclusive 

 owing to attacks on the cane of root grubs of Diaprepes abbreviates Linn, and Phylalus smithi 

 Arrow. In continuation of previous work with cane varieties, it was found (pp. 20-80) that 

 B. H. 10 (12), Ba. 0032 and B. 0450 have given best results in the order named over a large 

 number of experiments. Some newer seedlings such as B. S. F. 12 (27) and Ba. 115G9 are 

 also showing great promise. — J. S. Dash.

 Study No. 11. Mississippi Agric. Exp. Sta. Bull. 185: 1-18. 8 fig. 1919.— The object of this 

 investigation was to determine the effect of micro-organisms in the fermenting of green 

 manures and particularly the advantage of a light dressing of stable manure as compared 

 with that of a bacterial culture, in the utilization of green manures for plant food. In 

 carrying out the experiments two series of 3-gallon jars were used, one for the bacteriological, 

 and the other for the vegetative tests. Sandy silt loam soil poor in nutrient elements was 

 used. The green manures added were alfalfa, oats, and cow peas. Each pot to which bac- 

 terial emulsion was applied received an addition of about 25 billion germs. In every case an 

 increase in the amount of green manure turned under gave an increase in oat crop yield. 

 A maximum of 50 tons of the green manure was applied. A light dressing of a stable manure 

 or the addition of a bacterial culture with a green manure gave a marked increase in the 

 crop when 4 tons of the green manure were added. When 8 tons were added the effect was 

 practically neutral; when 16 tons were added a depressing effect was noted from the addition 

 of the germs, contained either in the manure or the bacterial culture. — The nitrogen content 

 of the oat crop produced varied directly with amount of crop produced. — The cumulative 

 effect of a green manure was marked. — H. B. Brown. 



37. Brown, H. B. Cotton experiments, 1918. Mississippi Agric. Exp. Sta. Bull. 186: 

 1-31. 3 fig. 1919. — This report gives results of cotton variety tests in five different sections 

 of the State in which the performance of standard varieties and new strains developed by the 

 Experiment Station were tested on different soil types. Cotton wilt and other studies made 

 at the College Station are also reported. All the varieties grown showed some wilt infection 

 but the wilt resistant varieties were damaged but slightly. Single stalk culture experi- 

 ments gave 2S per cent better yields for early thinning. Fruiting studies showed that some 

 varieties produced about 100 per cent more blossoms than others, and that some varieties 

 retained more than 50 per cent of their forms while others retained less than 30 per cent. 

 Germination counts and counts of number of seed in a given volume showed that the stand 

 secured varied inversely with the size of the seed planted. — H. B. Brown.

 and forage crop seeds. — F. A. Wolf.
