532 EXPERIMENT STATION RECORD. [Vol.37 



Winter wheat grown after a fallow and on land packed with a subsurface 

 packer gave a 4-year average yield of 26.2 bu., as compared with 26.8 bu. from 

 land not packed. The average yield from land packed by the surface packer 

 was 26.4 bu. Spring wheat after a fallow yielded an average of 20.1 bu. when 

 packed with the subsurface packer and 20 bu. per acre when not packed. 



In a comparison of no harrowing, light harrowing, and heavy harrowing and 

 weeding of the summer fallow for winter wheat, 4-year average yields for three 

 plowing dates April 1, May 1, and June 1 amounted to 24.2, 26.6, and 27.2 bu., 

 respectively. There was little difference between the treatments for any but the 

 earliest plowing date (April 1). when average yields of 25.6. 30.2. and 33.5 bu., 

 respectively, were secured. 



The average yield of winter wheat on plats harrowed in the spring amounted 

 to 26.4 bu., as compared with 27.4 bu. from plats not harrowed, thus indicating 

 that except for weed eradication spring harrowing of winter wheat is not 

 nece.ssary or desirable. 



Considerable tabulated data are presented and discussed, summarizing the 

 results obtained in rotation experiments with spring and winter wheat, spring 

 barley, spring oats, corn, field peas, and potatoes for the period of 1913-1916. 

 The results, however, are not considered conclusive. 



Progress report, Substation No. 4, Beaumont, Tex., 1909—1914, H. H. 

 Laxhje (Texas Sta. Bui. 200 (1916), pp. 3-lS, figs. 4).— The history and develop- 

 ment of this substation are briefly outlined and the work and results obtained 

 from its establishment through the crop season of 1914 are discussed. The 

 substation is located on a so-called " old rice field " at an elevation of from 

 26.5 to 29.8 ft. above sea level, near the southeastern corner of the State. Ked 

 rice, weeds, and grass common to old rice fields were present, and the whole 

 farm was characterized by the poor drainage facilities which predominate on 

 most of the rice farms of the region. The rainfall Is well distributed through- 

 out the year and totals approximately 45.09 in. 



Experimental work has dealt largely with rice and a study of the practices 

 i*elated to rice farming, including cultural methods and variety and rotation 

 tests. In date-of-seeding trials the average yields for 1913 and 1914 varied 

 from 270 lbs. per acre for seedlngs made March 24 to 1,600 lbs. for seedings 

 made June 3. Rate-of-seeding tests conducted during 1913 and 1914, employing 

 60-, 80-, and 100-lb. rates per acre, resulted in average yields of 1.270, 1,260, 

 and 1,525 lbs. per acre, respectively. A comparison of broadcasting with drill- 

 ing in rice on dry land in 1913 resulted in yields of 927 lbs. per acre witli the 

 former method and 1.930 lbs. with the latter. 



The yields of rice obtained in 1914 on plats sown to various other crops in 

 1913 are reported in tabuhir form. The highest yield of rice, amounting to 1.911 

 lbs. per acre, was secured after cotton, while the lowest yield, 1,068 lbs., was 

 obtained after rice. The legimies (cowpeas, peaimts, sweet clover, and soy 

 beans) also proved beneficial to the succeeding rice crop, giving yields ranging 

 from 1,721 lbs. after soy beans to 1,774 lbs. after cowpeas. Rice after fallow 

 yielded 1,412 lbs. 



Rod-row tests have been conducted with 122 varieties of rice and 3-year 

 average yields of 18 of these varieties are reported in tabular form. The 

 average yields reported varied from 3.23 lbs. per nursery row for the Chien-Yu 

 variety to 1,603 lbs. for the Honduras variety. 



Methods for the control of red rice, grass, and weeds are suggested. 



Hay crops have not proved very satisfactory, due to the high humidity pre- 

 vailing at harvest time. Sudan grass yielded 2.48 tons of cured hay per acre 

 from a 15-lb. rate of seeding in 1914, but suffered a large percentage of loss. 

 Japanese .^ugar cane (E. S. R.. 37, p. 140) is considered the best forage crop
