Sample size for estimating mean and coefficient of variation in species of crotalarias.

The objective of this study was to determine the sample size necessary to estimate the mean and coefficient of variation in four species of crotalarias (C. juncea, C. spectabilis, C.

Leaf area estimation from linear measurements in different ages of Crotalaria juncea plants.

The goal of this study was to estimate the leaf area of Crotalaria juncea according to the linear dimensions of leaves from different ages. Two experiments were conducted with C. juncea cultivar IAC-KR1, in the 2014/2015 sowing seasons.
