Determing Higher Fatty Acid Levels in Plant Materials NWISRL
Mayland, H.F..
The higher fatty acids (HFA) are important plant constituents that are implicated in the grass tetany hazard in livestock. A method is given whereby a technician can analyze 12 forage samples daily for HFA content. The method consists of saponifying the plant material in ethanol and KOH and extracting the subsequently acidified HFA with petroleum ether. The petroleum ether phase is evaporated and the HFA residue is dissolved in ethanol and then titrated with standardized isobutanolic KOH in the absence of Oxygen by using an Nitrogen atmosphere. A standard plant sample, analyzed over a 37-day period, had a mean of 136 mmol H+kg ± 4.5, where 0.1 mmol H+ℓ palmitic standard was determined with an accuracy of 99 ± 1.9%.

Growth and Nutritional Value to Cattle of Grasses on Cheatgrass Range in Southern Idaho NWISRL
Murray, R.B.; Mayland, H.F.; Van Soest, P.J..
Seven grass species--desert wheatgrass (Agropyron desertorum), streambank wheatgrass (Agropyron riparium), cheatgrass (Bromus tectorum), basin wildrye (Elymus cirtereus), Sandberg's bluegrass (Poa sandbergii), bottlebrush squirreltail (Sitanion hystrix), and needle-and-thread grass (Stipa comata)--were harvested to a 1/2-inch (1.2-cm) stubble height periodically between mid-March and December in most years from 1962 through 1968 at the Saylor Creek Experimental Range in southern Idaho. These samples were analyzed for N, P, S, Ca, Mg, K, Na, Zn, Mn, Cu, and Fe. Certain digestibility fractions (NDF, NDF-ash, DCW, DCW-ash free, and TDDM) were also determined on these samples. In addition, estimates of the soil chemical status, soil moisture contents...

Multivariate analysis and vigor tests to determine the quality of Brachiaria decumbens seeds Rev. Ciênc. Agron.
Silva,Givanildo Zildo da; Martins,Cibele Chalita; Bruno,Riselane de Lucena Alcântara; Pereira,Francisco Elder Carlos Bezerra; Jeromini,Tatiane Sanches.
ABSTRACT This study aimed to verify the efficiency of multivariate analysis in the identification of promising vigor tests for the evaluation of the physiological quality of seed lots of Brachiaria decumbens cv. Basilisk. Seeds of B. decumbens cv. Basilisk were tested for the following parameters: water content, germination, first germination count, cold test, electrical conductivity, seedling growth, seedling dry mass, first count and emergence percentage of seedlings in laboratory substrate, and seedling emergence in the field. The data obtained in each test-all completely randomized experimental designs-were analyzed separately by means of analysis of variance, Scott-Knott’s test, and multivariate analysis. Principal component analysis is efficient to...

Nitrate reductase activity and spad readings in leaf tissues of guinea grass submitted to nitrogen and potassium rates Rev. Bras. Ciênc. Solo
Lavres Junior,José; Santos Junior,João de Deus Gomes dos; Monteiro,Francisco Antonio.
Nitrogen and K deficiency are among the most yield limiting factors in Brazilian pastures. The lack of these nutrients can hamper the chlorophyll biosynthesis and N content in plant tissues. A greenhouse experiment was carried out to evaluate the relationship among N and K concentrations, the indirect determination of chlorophyll content (SPAD readings), nitrate reductase activity (RNO3-) in newly expanded leaf lamina (NL) and the dry matter yield for plant tops of Mombaça grass (Panicum maximum Jacq.). A fractionated 5² factorial design was used, with 13 combinations of N and K rates in the nutrient solution. The experimental units were arranged in a randomized block design, with four replications. Plants were harvested twice. The first harvest occurred...
