Among the various botanical families species that can be grown as green manures, stand out those of the Fabaceae family. Canavalia ensiformi showed significant higher values for the mean fresh mass bussav, dry mass and productivity in relation to Dolichos lablabbeing recommended for cultivation in Brazilian Cerrado.
Although the data can produce reliable results in a given study, it is important to determine the sample size in order to estimate the average of each variable, with high confidence and a given estimation error. Tamanho da amostra para estimativa da biomassa e produtividade de Canavalia ensiformis e Dolichos lablab. Moreover, this is a crop that can be considered for family farms because of its high seed production and high prices in the market.

According to Teodoro et al. Densidades de semeadura de leguminosas na melhoria da qualidade do solo e na produtividade do milho. However, other factors must be analyzed for planning experiments with these green manures, such as seed germination, plant density, spacing to be used and type of harvesting and weeding manual or mechanical. No base fertilization and coverage for any culture were used. Analyzing the variation coefficient of both green moerttin verifies a superior magnitude of fresh and dry masses and productivity, suggesting the need of higher sample sizes for the estimation of the fresh and dry mass relative to average productivity.
Sample size to estimate biomass and productivity of Canavalia ensiformis and Dolichos lablab.

The calculation of central tendency, variability, asymmetry, kurtosis and Lilliefors test relatively to morphological variables fresh mass, dry mass and C. Forty five plants were randomly selected in the experimental area of each crop to determine fresh mass, busswb mass and yield. Porto Alegre, Bookman, p. Conclusions Canavalia ensiformi showed significant higher values for the mean fresh mass production, dry mass and productivity in relation to Dolichos lablabbeing recommended for cultivation in Brazilian Cerrado.
The Cerrado occupation has occurred quickly, based on intensive estatisticz systems, which have increased the processes of soil degradation Silva et al.
Como citar este artigo. Given these considerations in relation to moregtin, it can be inferred that the data from these variables provide credibility to the scaling of the sample size study. These results showed lower magnitude than those observed by Melo that in evaluating the fresh and dry mass production in different green manures did not identify statistical difference in the C.

Bazica, the statistical values revealed existence of genetic basiica among C. In agricultural systems in areas of Cerrado are used intercropped with maize and perennial crops, because tolerates partial shade Carvalho and Amabile, Introduction The Cerrado occupation has occurred quickly, based on intensive production systems, which have increased the processes of soil degradation Silva et al.
From a practical standpoint, it can be inferred that it is difficult to obtain average estimates of the variables evaluated in C. Considering these same parameters for the D.
Sample size to estimate the average of each character in C. Data eetatistica extrapolated to t ha -1and measures of central tendency, variability, asymmetry and kurtosis were calculated and normality of the variables under study was checked by Lilliefors test Campos, Results and Discussion Estatistia calculation of central tendency, variability, asymmetry, kurtosis and Lilliefors test relatively to morphological variables fresh mass, dry mass and C.
Estztistica, the objective of this research was to determine the sample size to estimate biomass and productivity of C. These processes result in impacts that often generate the inefficiency of agricultural systems, with frequent need for interventions through conservation practices to maintain the productive potential of the soil.
In the Cerrado of Central Brazil is sown until the end of the rainy season, because of drought resistance and little sensitivity to photoperiod Calegari et al. Variables evaluated in C.
Among the desirable characteristics for selection bussaab species for green manure, stands out mainly dry mass production, because it is related to the capacity to increase nutrient by symbiosis with microorganisms, soil cover and recycling of nutrients Chaves and Calegari, In this context, green manure becomes fundamental to the Cerrado region, because it promotes protection, improvement and maintenance of soil quality, as well as substantial increases in soil organic matter and nutrients, benefiting agroecosystems Carvalho et al.
At maturation, 45 plants were randomly selected in the experimental area of each crop to determine fresh mass, dry mass estatistics productivity. These results confirm the variability among the variables and moretti green manure species, corroborating the results obtained by Cargnelutti Filho et al. The legumes, in addition to providing similar benefits to other species, have the ability to accumulate N through biological fixation Silva et al.
In this scenario, the present research aimed to determine the sample size for the estimation of biomass and productivity expected values of Canavalia ensiformis and Dolichos lablab.
Embrapa Cerrados, 28 p. Measures of central tendency, variability, asymmetry f kurtosis were calculated and normality of the variables under study was checked by the Lilliefors test.
