Automating Uniformity Trials to Optimize Precision of Agronomic Field Trials [PDF]
Agronomy, 2021 Plot size has an important impact on variation among plots in agronomic field trials, but is rarely considered during the design process. Uniformity trials can inform a researcher about underlying variance, but are seldom used due to their laborious ...

Uniformity trials size for estimating cherry tomato plot size
Revista Ciência Agronômica, 2018 The aim of this study was to determine how the size of the uniformity trial influences the estimation of cherry tomato plot size. The size of plot required to evaluate the mean length of fruit per plant, mean fruit width per plant, mean fruit weight per ...

A note on the value of uniformity trials for subsequent experiments [PDF]
The Journal of Agricultural Science, 1930 The question attacked is whether soil variations are sufficiently constant from year to year to give useful corrections to the yields of experimental plots from their yields under previous uniformity trials, and the data investigated were the published results of uniformity trials carried out on two fields at Aarslev (Denmark) between 1906 and 1911. In

Simulation and test of a V-shaped seed-guiding surface and concave pit furrow opener for seed displacement restriction: Verification on seeding uniformity and post-soil-contact seed motion limitation. [PDF]
PLoS ONEIn plot breeding tests, sowing uniformity directly impacts the accuracy of crop genetic improvement trials. Existing furrow openers often cause spacing fluctuations and lateral seed drift due to structural limitations.

Need for Uniformity in Collection and Reporting of Data in Cancer Clinical Trials [PDF]
Journal of the National Cancer Institute, 1990 The National Cancer Institute (NCI) has recently publicized the need for increasing accrual of patients to clinical trials. A recent editorial by NCI officials stated that currently only l%-3% of patients afflicted with the major forms of cancer are treated on NCI-supported trials (7).

Uniformity trials simulation to determine the statistical power in yield rice trials
, 2021 Introduction. Prospective analysis of the statistical power of a hypothesis test should be one of the most important stages in any experiment, however, it is frequently omitted. In Costa Rica, within the literature consulted, no research related to this topic was found for yield experiments in rice cultivation. Objective. To simulate ...

Size of uniformity trials for estimating the optimum plot size for vegetables [PDF]
Horticultura Brasileira, 2015 The aim of this work was to determine the uniformity trial size for estimating the optimum plot size in order to evaluate the fruit mass of tomato, snap-beans and zucchini. The mass of fruits was evaluated in uniformity trials with tomato grown in plastic tunnel in spring-summer and autumn-winter seasons, with snap-beans in plastic greenhouse in autumn-
