Survey data collected during a grassland-recording investigation showed a strong positive correlation between nitrogen input and the output of utilized starch equivalent per acre. At the levels of output covered, sward type was not very important in relation to total yield. Herbage species were important for other reasons and the choice of seeds mixtures should be determined by factors such as earliness and lateness of growth and resistance to disease and drought. The survey showed that well-managed ley and permanent pasture are both capable of producing at a high level. A disturbing feature of the results was the low production of most spring resowings, primarily as a result of poor management. Although the records were obtained from an above-average group of farms, the results have general application. Potential responses to fertilizers may be even greater on less intensive farms, especially with regard to phosphate and potash. However, the level of production of a field will always depend finally on the level of management exercised by the farmer himself. [ABSTRACT FROM AUTHOR]

Presents recommendations for recording the utilized output of grassland on dairy farms. Assessment of the utilized output of individual fields by cow-day or by standard cow-equivalents; Factors relating categories of cattle to the adult animal; Significance of proportionate allocation of grazing to individual fields.

Presents a comparison of the traditional method of calculating the utilized-starch-equivalent (U.S.E.) output of grazing fields for livestock with a recommended quicker method. Causes of variations between the traditional and recommended methods of calculating U.S.E.; Benefits of the recommended method for milk production and concentrate feeding; Implication of the monthly use of U.S.E. factor on the utilization of grass by dry stock.

Presents a study on tools and technique for sampling pit silage to determine dry matter and density. Aspect of assessing the output of individual fields considered to be the more difficult; Way in which the researchers were able to obtain accurate estimates of sampling for density and dry matter; Comparison of the two samplers in terms of dry matter and density.

A system called Performance Determined Instruction (PDI) is presented as a methodological tactic for training in remedial reading. The system incorporates aspects of binary logic, instrumental conditioning, and programmed instruction. Results suggest that PDI is a high-precision instructional procedure effective in obtaining desired changes in reading-task performance.
