Biomass sorghum has emerged as an alternative crop for biofuel and bioelectricity production. Fresh biomassyield (FBY) is a quantitative trait highly correlated with the calorific power of energy sorghum cultivars, but alsohighly affected by the environment. The main goal of this study was to investigate the genotype-by-environmentinteraction (G × E) and the stability of sorghum hybrids evaluated for FBY across different locations and years,using factor analytic (FA) mixed models and environmental covariates. Pairwise genetic correlations betweenenvironments ranged from -0.21 to 0.99, indicating the existence of null to high G × E. The FA analysis unveiledthat solely three factors explained more than 79% of the genetic variance, and that more than 60% of theenvironments were clustered in thefirst factor. Moderate correlations were found between some environmentalcovariates and the loadings of FA models for environments, suggesting the possible factors to explain the high G× E between environments clustered in a given factor. For example: precipitation, minimum temperature andspeed wind were correlated to the environmental loadings of factor 1; minimum temperature, solar radiation andaltitude to factor 2; and crop growth cycle to factor 3. The latent regression analysis was used to identify hybridsmore responsive to a set of environments, as well as hybrids specifically adapted to a given environment. Finally,FA models can be successfully used to identify the main environmental factors affecting G × E, such as minimumtemperature, precipitation, solar radiation, crop growth cycle and altitude.

Avaliou-se, em casa de vegetacao, a producao de materia seca de Brachiaria decumbens cv. Basilisk, cultivada em uma Areia Quartzosa alica, proveniente da camada aravel de uma pastagem degradada, estudaram-se as seguintes fontes de fosforo: 1- superfosfato triplo, 2- termofosfato silico-magnesiano, 3- fosfato de Gafsa, 4- fosfato de Arad, 5- fosfato da Carolina do Norte e 6- fosfato de Araxa, nas doses de O, 50, 100, 200 e 400 kg de P2O5 total/ha. Estudou-se tambem, nas doses 0 e 100 kg de P2O5 total/ha, a interacao com ) e 1,5t de calcario/ha nos tratamentos 1, 2, 3 e 6. Observaram-se efeito das fontes no aumento da producao de materia seca e diferencas significativas entre as mesmas. Os resultados confirmam a baixa solubilidade e o baixo indice de eficiencia agronomica do fosfato de Araxa. A adicao de calcario promoveu incremento de 14% na producao dos tratamentos com superfosfato triplo. A interacao entre calcario e fosfato de Araxa foi negativa, reduzindo a producao em 32%. |
