Comparison of tomato root distributions by minirhizotron and destructive sampling

Measuring root turnover using the minirhizotron technique

Cheng, W.-X., Coleman, D.C. and Box, J.E., Jr., 1991. Measuring root turnover using the minirhizo° tron technique. Agric. Ecosystems Environ., 34: 261-267. Measurement of root turnover has been one of the most difficult problems in terrestrial ecosystem studies owing to the lack of an appropriate method. In this paper, a method for measuring intraseasonal root turnover is described. The recentl...

Sampling and Sampling Distributions

A sample is a group of objects or readings taken from a population for counting or measurement. We shall distinguish between two kinds of populations — finite populations and infinite populations. The sample must be random, meaning that all possible samples of a particular size must have equal probabilities of being chosen from the population. This will prevent bias in the sampling process.

a comparison of teachers and supervisors, with respect to teacher efficacy and reflection

supervisors play an undeniable role in training teachers, before starting their professional experience by preparing them, at the initial years of their teaching by checking their work within the proper framework, and later on during their teaching by assessing their progress. but surprisingly, exploring their attributes, professional demands, and qualifications has remained a neglected theme i...
