Authors: Howell R. W. , Wargel C. J. , Brim C. A. , Hartwig E. E. , Lambert J. W. , Thompson J. R. , Stefansson B. R. , Park J. K. , Seigler W. E. , Webb B. K. 
Published: July 2010

SynopsisThe response of soybeans to seed treatment with gibberellin was studied at eight locations from Winnipeg, Man., to Coahoma, Miss. Stands and yields were reduced by applications of either 2 or 8 g. potassium gibberellate per bushel of seed. While treated plants were taller in the seedling stage, at maturity the controls were more than 5 inches taller than treated plants in most cases. Maturity and oil and protein contents of the seed were not affected consistently by gibberellin treatment.
Sterility in Sudangrass: I. Barren‐ and Chimeral Partial‐Sterility1
Authors: Townsend C. E. 
Published: July 2010

SynopsisA barren‐sterile character, manifested by the absence of floral parts and sexual organs, was inherited as a monogenic recessive. A few seeds were observed on barren‐sterile plants in one progeny. The chimeral partial‐sterile character was believed to be controlled by recessive genes which were quite mutable. The mode of inheritance was not determined.
Nitrogen Utilization in High and Low Protein Wheat Varieties1
Authors: Seth Jagdish , Hebert T. T. , Middleton G. K. 
Published: July 2010

SynopsisNo differences were found in total nitrogen content of vegetative parts of high and low protein wheat varieties prior to heading. After heading nitrogen increased more rapidly in the heads of high protein varieties. Varietal differences in protein content of the kernels were not decreased by growing plants in solution culture, or by foliar applications of urea or nitrate nitrogen.
Influence of Fertilizer Analysis and Placement on the Emergence, Growth, and Nutrient Absorption by Wheat Seedlings in the Greenhouse1
Authors: Lawton K. , Davis J. F. 
Published: July 2010

SynopsisUnder greenhouse conditions, contact placement of wheat seed with 5‐20‐20 fertilizer at the rate of 500 pounds per acre seriouly delayed and reduced emergence of seedlings and subsequent growth. Similar placement of seed with 5‐20‐0 fertilizer was only slightly detrimental. Applying mixed fertilizer in a band below or 1½ inches to the side and 1½ inches below the seed was most desirable from standpoint of emergence, growth, and uptake of fertilizer phosphorus.
Forage Production of Vernal Alfalfa Under Differential Cutting and Phosphorus Fertilization1
Authors: Parsons J. L. , Davis R. R. 
Published: July 2010

SynopsisA comparison of 6 cutting schedules with 3 phosphorus levels indicated that Vernal alfalfa produced maximum dry matter when cut 3 times annually. When cut 4 times the total protein production was the same but the percent protein was higher. Phosphorus applications helped to overcome detrimental effects of severe cutting schedules.
The Physiological Nature of Gene‐Controlled Growth Form in Trifolium Fragiferum L. I. Inheritance of Growth Form1
Authors: Bendixen Leo E. , Stanford E. H. , Peterson M. L. 
Published: July 2010

SynopsisErect versus stoloniferous growth form in Salina strawberry clover is determined by a single gene, with stoloniferous being dominant over erect. Somatic reversion to the stoloniferous form is common in erect plants. Apparent instability patterns among six erect parents and their progenies at the erect locus suggest genetic control of this instability.
Sterility in Sudangrass: II. Random and Nonrandom | Partial‐Sterility1
Authors: Townsend C. E. 
Published: July 2010

SynopsisPlants classified as having random partial‐sterility possessed normal appearing reproductive organs, although approximately 50% seed failure and 50% pollen abortion occurred. It was believed that this type of sterility was due to cryptic structural hybridity. Abnormal pistil development was characteristic of plants classified as nonrandom partial‐sterile. The breeding hehavior suggested that this character was genie controlled.
Root Development of Potatoes1
Authors: De Roo H. C. , Waggoner P. E. 
Published: July 2010

SynopsisRoot penetration of potatoes was inhibited at plow depth by the hardpan which was induced by normal tillage. A complete shattering of this pan favored a deep and well‐developed root system. In fine sandy loam, compaction by traffic in the spray‐wheel furrow also restricted horizontal root development.
Effect of Gibberellic Acid Upon Seedling Emergence of Slow and Fast Emerging Wheat Varieties1
Authors: Allan Robert E. , Vogel O. A. , Craddock J. C. 
Published: July 2010

SynopsisSoaking seeds in solutions of gibberellic acid stimulated slow‐emerging wheat varieties to emerge at rates comparable to rapid‐emerging varieties under both greenhouse and field conditions. Gibberellic acid treatment adversely affected seedling survival of 3 rapid‐emerging varieties but did not influence survival of 2 slow‐emerging varieties. Treatment did not stimulate coleoptile elongation of any varieties tested.
Number of Lines Needed in Oat‐Variety Purification1
Authors: Wheat J. G. , Frey K. J. 
Published: July 2010

SynopsisMorphologically similar lines of Mo. 0‐205 and Clintland oat varieties derived from individual heads did not differ in yield at a single testing site or when the data from different sites were combined. Therefore, it is not necessary to select several hundred heads when repurifying an oat variety. One of 24 lines of Bonham was inferior in yielding ability.
Water Utilization by Field Corn in Western Minnesota1
Authors: Holt R. F. , Van Doren C. A. 
Published: July 2010

SynopsisAvailable soil water in depths to five feet indicate water usage to the fifth foot at kernel formation. The period of highest water requirement appears to be from tasseling to kernel formation. Water requirements decreased sharply after kernel formation. Forty to 50% of the water losses during the growing season could be accounted for by evaporation.
Bromegrass and Bromegrass‐Alfalfa Yields as Influenced by Moisture Level, Fertilizer Rates, and Harvest Frequency1
Authors: Lorenz Russell J. , Carlson Carl W. , Rogler George A. , Holmen Harold 
Published: July 2010

SynopsisDry‐matter yields of bromegrass and a bromegrass‐alfalfa mixture were significantly increased by the application of irrigation water as compared with no irrigation. Irrigating at various soil moisture levels, however, had little or no effect on yield. Nitrogen fertilizer increased yields at all levels of soil moisture regardless of whether the forage was harvested at hay stage or clipped frequently to simulate removal of the forage by grazing. The percentage alfalfa in mixture with bromegrass increased with irrigation.
Effect of Nitrogen Fertilizer on Emergence and Seedling Growth of Forage Plants and Subsequent Production1
Authors: Ward C. Y. , Blaser R. E. 
Published: July 2010

SynopsisNitrogen fertilizer applied at time of seeding influenced the percentage of emergence of all species in each seeding in proportion to the amount of nitrogen applied. In two experiments significant reductions in stands resulted. Seedling weights 28 days after emergence were not influenced by nitrogen fertilization; 56 days after emergence seedling weights were increased by higher nitrogen rates. Yields were usually depressed. Red clover and Ladino clover were depressed more than alfalfa and birdsfoot trefoil.
Effects of Seed Treatment and Foliar Spray Applications of Gibbberellic Acid on Grain Sorghum1
Authors: Pauli A. W. , Stickler F. C. 
Published: July 2010

SynopsisRates of laboratory germination were increased by gibberellic acid in three varieties of grain sorghum. Field emergence rate in Midland grain sorghum was increased by dust and slurry applications to seed. Final emergence, maturity, plant height, grain yields, and components of yield were not influenced. Yields were not consistently increased by foliar sprays.
Effect of Fertilization on the Crude Fiber Content and Crude Fiber‐Nitrogen Relationship of Coastal and Common Bermudagrasses1
Authors: Miller W. J. , Donker J. D. , Adams W. E. , Stelly M. 
Published: July 2010

SynopsisThe crude fiber content of Coastal bermudagrass was not affected by level of N, P, or K fertilization. Only N fertilization materially influenced the nitrogen content of this forage. When clipping date was not a variable, the crude fiber and nitrogen content of Coastal forage were not significantly correlated. Increasing N fertilization reduced the crude fiber content of common bermudagrass. The correlation between crude fiber and nitrogen of this forage was −0.49.
Response of Red Clover Varieties at High Elevations in Colombia1
Authors: Crowder Loy V. , Echeverri Silvio 
Published: July 2010

SynopsisAt the first harvest, varieties from southern United States exceeded the others in seedling vigor and forage yields. In subsequent harvests, varieties from 38° to 45° N were equal or superior. The production of varieties originating above 50° N was low. Flowering decreased in order for southern, middle, and northern varieties. Medium red varieties were characterized on the basis of growth type. A shift in type was noted when seeds had been multiplied in a region different from that of varietal origin.
Effect of Topping on Moisture Loss, Dry Matter Accumulation, and Yield of Corn Grain1
Authors: Cornelius P. L. , Russell W. A. , Woolley D. G. 
Published: July 2010

SynopsisCorn topping resulted in significant increases in rate of moisture loss for some treatments, but all reductions were small and appeared to be of no practical value. Topping below the 6th leaf on or before 40 days after silking in 1958 and on or before 30 days in 1959 gave significant yield reductions. Some significant yield reductions resulted when fewer leaves were removed, but these results were not consistent.
Effects of Physiological Quality of Seeds on Total Germination, Rapidity of Germination, and Seedling Vigor1
Authors: Webster Lionel V. , Dexter S. T. 
Published: July 2010

SynopsisSeeds of barley, wheat, beans and corn were mistreated with mechanical abuse, with high temperatures, or with storage at high relative humidity. Percentage germination, rapidity of germination and size of seedlings were determined. It is suggested that the quality of seeds might be determined by consideration of which one of these qualities first shows deterioration.
Corn Yield Response to Applied Phosphorus as Affected by Rainfall and Temperature Variables1
Authors: Engelstad O. P. , Doll E. C. 
Published: July 2010

SynopsisJune plus July rainfall accounted for 75% of the variation in maximum yields of corn with increasing rates of applied P over a 12‐year period at Greenville, Ky. While the level of net return was strongly dependent upon June plus July rainfall, the actual yield responses to applied P and the optimum application rates of P were largely independent of the above rainfall variable.
Cotton Fruiting as Affected by Soil Moisture Regime1
Authors: Bruce R. R. , Shipp C. D. 
Published: July 2010

SynopsisFruit production of cotton plants grown in plots maintained within 0.16 to 0.33 atmosphere mean soil moisture tension range until 6 weeks past first bloom followed by 2 weeks in the range 0.34 to 0.50 atmosphere was not significantly lower than that of plants grown at the low tension throughout. Maintaining the higher mean soil moisture tension throughout the 8 weeks past first bloom significantly reduced cotton fruiting but increased the lint production per inch of applied water.
Effect of Duration and Timing of Low Soil Oxygen Content on Shoot and Root Growth
Authors: Letey J. , Stolzy L. H. , Blank G. B. 
Published: July 2010

SynopsisShoot growth was critically damaged when soil containers were placed in nitrogen at early stages of growth before roots became well established. Root growth essentially ceased when placed in the nitrogen atmosphere and there was a time lag in recovery when placed in a “normal” atmosphere. All species studied, cotton, sunflower, and green beans, showed similar results.
Effects of Heating and Storage on the Viability of Grass Seed Harvested with High Moisture Content1
Authors: DeWitt J. L. , Canode C. L. , Patterson J. K. 
Published: July 2010

SynopsisSeed harvested by the windrow method germinated the same regardless of moisture levels at harvest and was consistently superior in germination to that of direct‐combined seed. Seed combined at less than 25% moisture did not heat appreciably in storage and there was no loss in germination as a result of immediate heating. Delta Kentucky bluegrass seed harvested at more than 22% moisture and Manchar smooth bromegrass seed harvested at more than 24% moisture had a lower germination when stored in bags for 2 weeks after harvest.
Effectiveness of Inorganic Nitrogen as a Replacement for Legumes Grown in Association with Forage Grasses. I. Dry Matter Production and Botanical Composition1
Authors: Carter Lark P. , Scholl J. M. 
Published: July 2010

SynopsisYields of orchardgrass and bromegrass were increased significantly by each increment of nitrogen with 0, 30, 60, 120, and 240 pounds per acre rates. Orchardgrass tended to outyield bromegrass at higher N rates. Application of N to grass‐legume mixtures resulted in increased yield of dry matter due to increased growth of the grass component.
Response of Four Pasture Grasses to Nitrogen in the Dry Tropics1
Authors: Oakes A. J. , Skov O. 
Published: July 2010

SynopsisYields of Coastal bermudagrass, rhodesgrass, pangolagrass, and stargrass increased markedly following split applications of nitrogen at rates up to 300 pounds of N per acre annually. The recovery and efficiency with which the applied nitrogen was utilized varied with grass species and nitrogen level. Ranked in descending order of yield and efficiency of nitrogen utilization in forage production the grasses are: rhodesgrass, Coastal bermudagrass, stargrass, and pangolagrass.
Root Weight and Distribution of Blue Panicgrass, Panicum antidotale Retz., as Affected by Fertilizers, Cutting Height, and Soil‐Moisture Stress1
Authors: Wright Neal 
Published: July 2010

SynopsisRoot distribution by weight to a depth of 12 feet showed 70% of the roots in the top 2 feet. A significant root weight increase resulted from nitrogen fertilizer with maximum response at the 525‐pound level. Root weights were significantly increased when 525 pounds of P was applied with 175 pounds of N. No further increase occurred when N was increased to 875 pounds per acre. Other treatments and interactions were nonsignificant (P, K, NK, and PK),. Root weights were significantly reduced with lower clipping heights and lower soil‐moisture‐stress depths. Responses to clipping height and soil moisture were linear.
Cloddy and Conventional Seedbeds for Wheat Production in the Northwest1
Authors: Horning T. R. , Oveson M. M. 
Published: July 2010

SynopsisWinter wheat seeded in multiple‐ and single‐tilled seedbeds produced comparable yields over a 6‐year period. The annual cost of from 2 to 4 additional tillage operations required to prepare finely worked seedbeds varied from $2.00 to $4.50 and averaged $2.88 per acre.
Influence of Rate and Method of Planting on Several Components of Irrigated Corn Yields1
Authors: Colville W. L. 
Published: July 2010

SynopsisThe ratio of ears produced to mature plants was the major contributor to increased yields which resulted from drilled over hill‐dropped and checked corn grown under irrigated conditions in Nebraska. Although this ratio decreased with increasing population, the greater number of ears per acre accounts for much of the grain yield increase when planting rates were increased. Components of yield were linearly correlated with population but not with yield due to the curvilinear relationship of yield to population.
Some Effects of Nitrogen Fertilizer, Maturity, and Light on the Composition of Orchardgrass1
Authors: Gordon C. H. , Decker A. M. , Wiseman H. G. 
Published: July 2010

SynopsisNitrogen‐fertilized orchardgrass forage contained more crude protein, nitrate, and water than control forage. The effects were less marked with advancing maturity but continued through the seed stage. Fertilized forage contained less sugar previous to flowering. Composition changes were greater when fertilized plants were shaded. The highest mean nitrate level observed was 2.4%.
Sodic Tolerance of Tall Wheatgrass1
Authors: Carter David L. , Peterson H. B. 
Published: July 2010

SynopsisTall wheatgrass grew and produced well at ESP (exchangeable‐sodium‐percentage) levels between 50 and 60 under field conditions. In the greenhouse, tall wheatgrass germinated and produced at ESP levels of 60, with transplants exhibiting superior performance. Seeds germinated with no adverse effects at pH levels up to 9.7. Plants grew at pH levels of 10.0 in solution culture.
Investigations of Ammonium Chloride as a Fertilizer for Forage Crops and Corn1
Authors: McClure George W. , Hunter Albert S. 
Published: July 2010

SynopsisAt low to moderate rates of nitrogen, crop yield increases from ammonium chloride compared well with those from ammonium sulfate. When high rates of nitrogen as ammonium chloride were broadcast on growing grass, some damage to stand resulted. At high rates, and especially when in contact with plant leaves, chloride was more toxic to timothy than sulfate was. Most of the chloride applied to well‐drained soils was lost by leaching within one year.
An Evaluation of Losses Caused by Hessian Fly in a Wheat Fertilizer Experiment1
Authors: Okigbo Bede N. 
Published: July 2010

SynopsisLosses attributed to hessian fly in wheat grown at 3 levels of nitrogen in the presence or absence of 2 levels of phosphorus and potassium were evaluated. Infestation and losses due to hessian fly were highest at the highest levels of nitrogen.
Crownvetch for Highway Bank Stabilization in the Piedmont Uplands of Georgia1
Authors: Richardson E. C. , Diseker E. G. , Hendrickson B. H. 
Published: July 2010

SynopsisCrownvetch was established on highway cut slopes in the Piedmont Uplands of Georgia by seedings and transplantings made in the fall and early spring. Either mulch or a nurse crop on all slope and soil conditions was usually required to protect the seedlings in their early stages. Best protection was obtained when crownvetch was seeded in combination with Abruzzi rye as a nurse crop.
Yield, Percent Nitrogen, and Total Nitrogen Uptake of Various California Annual Grassland Species Fertilized with Increasing Rates of Nitrogen1
Authors: Jones Milton B. 
Published: July 2010

SynopsisNear maximum yields resulted where 80 pounds N per acre were applied, but carryover was measurable only where 160 pounds were used. In nonleguminous plants, percent N increased with N rates during the vegetative stage, but at maturity it was less where 40 pounds N were applied than in the control. N uptake increased with N rate during winter, but uptake on unfertilized plots during the spring approximated that on plots receiving 40 pounds of N.
Effect of Liming and Potassium Fertilization on the Yield and Composition of an Alfalfa‐Orchardgrass Association1
Authors: MacLeod L. B. , Bradfield Richard 
Published: July 2010

SynopsisLiming increased the dry matter yields of oats and of an alfalfa‐orchardgrass mixture. Response to K increased with increased base saturation of the soil, and survival of alfalfa plants on soil limed to pH 5.5 or higher was largely dependent on K supply. Alfalfa was the dominant species where there was sufficient K for both components and orchardgrass dominated where K was limited. Total available carbohydrates in the storage organs of each species increased with K fertilization.
Some Effects of Emulsified Hexa‐Octadecanol on Germination, Establishment, and Growth of Kentucky Bluegrass
Authors: Atsatt P. R. , Bliss L. C. 
Published: July 2010

SynopsisGermination was reduced by treatment of seed but increased by treatment of soil surface to maintain high soil moisture content. In the field, 450 pounds per acre of the emulsion gave greatest increases in germination, percent cover, and dry weight yields.
Effects of Oats‐Rape Interseeding and Lamb‐Grazing on Corn Yield1
Authors: Marten G. C. , Jordan R. M. , Fedin W. F. 
Published: July 2010

SynopsisEarly‐summer interseeding of an oats‐rape mixture in corn followed by mid‐summer to fall pasturing with lambs generally caused a loss in corn yield during 1960 to 1962. Lamb gains were variable, and usually not sufficient to offset corn yield losses. Under ideal corn‐growing conditions and with a 43‐day grazing period (July 20 to September 1), corn yields were not adversely affected by the interplanted crop or the grazing lambs in 1961. Corn yields and lamb gains generally decreased when grazing continued after early September.
Phosphorus Uptake by Plants and Readily Extractable Phosphorus in Soils1
Authors: Blanchar R. W. , Caldwell A. C. 
Published: July 2010

SynopsisPhosphorus uptake from calcareous and noncalcareous soils was correlated with available P as determined by five methods. With calcareous soils all of the methods except the 1‐to‐10 Bray No. 1 were suitable for estimating available P. With noncalcareous soils the best correlations between uptake and available P were obtained using the Morgan and water solubility methods. Relationships between available P and soil properties such as amount and kind of carbonates in calcareous soils and forms of P were examined.
Influence of Nitrogen on Seasonal Production of Dry‐Matter and Nitrogen Accumulation From Meadows1
Authors: Rumburg C. B. , Wallace Joe D. , Raleigh R. J. 
Published: July 2010

SynopsisDifference in dry‐matter yields among plots given different levels of N fertilizer gradually increased to a maximum at time of maximum yield. The time of maximum yield occurred later in the growing season on plots fertilized with N than on unfertilized plots. During early stages of growth the internal concentration of N in herbage increased with each increment of applied N. The rate of dilution of internal N increased with increasing levels of applied N.
Evaluation of Short Stature Winter Wheats (Triticum aestivum L.) for Production under Texas Conditions1
Authors: Porter K. B. , Atkins I. M. , Gilmore Earl C. , Lahr Keith A. , Scottino Paschal 
Published: July 2010

SynopsisShort stature winter wheats yielded more than taller commercial varieties in irrigated trials and on dryland in a 35‐inch rainfall area but about the same or less on dryland in areas having 25 and 20 inches of annual rainfall. One short wheat strain responded the same as the taller variety, ‘Concho’, to differences in row spacing and planting rate but gave a greater yield response to a high rate of applied nitrogen. Quality characteristics were not associated with plant height.
Interrelationship of European Corn Borer, Plant Populations, Nitrogen Levels, and Hybrids on Stalk Quality of Corn1
Authors: Zuber M. S. , Dicke F. F. 
Published: July 2010

SynopsisCrushing strength of a 2‐inch mature stalk section was shown to be a suitable method of determining stalk damage by the European corn borer.
Pre‐emergence, Preplanting and Postemergence Herbicides for Alfalfa and Birdsfoot Trefoil1
Authors: Peters Elroy J. 
Published: July 2010

SynopsisHerbicides reduced yields of weeds and increased yields of alfalfa and birdsfoot trefoil during the seedling year. EPTC did not control broadleaved weeds as well as neburon or 4‐(2,4‐DB), but EPTC was superior to neburon for weed‐grass control. General weed control was obtained with neburon and with 4‐(2,4‐DB) in combination with dalapon or EPTC. None of the herbicide injured legumes to any extent.
Effect of Exchangeable Sodium Percentage on the Growth and Absorption of Essential Nutrients and Sodium by Five Crop Plants1
Authors: Bains S. S. , Fireman Milton 
Published: July 2010

SynopsisGreenhouse experiments indicate that sorghum is a good crop for studying exchangeable sodium‐fertility interrelationships. For the five crops studied, exchangeable sodium generally caused an increase in the absorption of sodium, nitrogen, and molybdenum, and a decrease in the absorption of calcium, potassium, sulfur, manganese, copper, zinc, boron, and chlorine.
