Emphasis is placed on the usefulness of statistics in analyzing exptl results. Definitions are given of basic concepts and terminology. The designs most frequently used in cassava expt are completely randomized, randomized complete blocks, split plots and systematic (response surface, fan-shaped ...

Utilizacion de la estadistica y el diseno experimental en investigacion en yuca
In Sept.-Dec. 1976 the ICA- Guali bean var. was planted (200,000 plants/ha) at CIAT, (Palmira, Colombia) to study the heterogeneity of the experimental plot; to map fertility trends and to determine correlation coefficients for adjoining plots as measures for these trends; to determine several pl...

In choosing an experimental design, emphasis should be placed on selecting one that minimizes experimental error variance. A comparison is made of the randomized complete block and lattice designs, giving the advantages and disadvantages of each. It was found that the lattice design was much bett...

Eficiencia relativa del diseno en latices con respecto al diseno en bloques completos al azar en ensayos de rendimiento en frijol (Phaseolus vulgaris L.)
A yield trial with 25 black bean varieties was carried out on the CIAT experimental farm (Palmira, Colombia) to ascertain the efficiency and accuracy of a 5 x 5 lattice design with different no. of replications (2-6) and plot sizes (1, 2, 4 and 6 rows/plot with 1.5, 3.0, 6.0 and 9.0 m(2) areas, r...

The simultaneous effect that lateral and end border rows may have on yield was studied in experimental plots at CIAT (Palmira, Colombia), using 25 black bean varieties in a 5 x 5 balanced lattice design with 6 replications. Plots measured 12 m(2) (6 rows, 4 m long). Unharvested end rows measured ...
