Dry bean is an important legume for human consumption in South America. A greenhouse experiment was conducted to evaluate uptake and use efficiency of macro- and micronutrients by six dry bean genotypes at two P levels (25 and 200 mg kg-1 soil). Shoot dry weight and grain yield varied significantly among genotypes and significantly increased with increasing phosphorus (P) levels. Grain harvest index (GHI) and 100-grain weight also differ significantly among genotypes and significantly increased with the increasing P levels. Based on grain yield efficiency index (GYEI), genotypes were classified as efficient and inefficient. The most efficient genotype was CNFP 10104, and inefficient genotypes were CNFP 10103 and CNFP 10120. Number of pods per plant and number of seeds per pod increased significantly with the addition of 200 mg P kg-1 of soil compared to the low level of P (25 mg P kg-1). Similarly, nitrogen (N), P, calcium (Ca), magnesium (Mg), sulfur (S), zinc (Zn), copper (Cu), and manganese (Mn) concentrations and uptake in the shoot and grain also significantly varied among genotypes. Uptake of macro- and micronutrients was greater under the greater P rate compared to the low P rate. This may be related to greater shoot or grain yield at 200 mg P kg-1 soil compared to 25 mg P kg-1 of soil. |

ABSTRACT: Most studies about soil organic carbon stock changes in the Cerrado (Brazilian Savanna) biome are either related to field data collected in clayey Ferralsols or different land uses, as if they were in equilibrium. This study aimed to evaluate the effect of tillage systems and crop sequences on the soil organic carbon stock and crop yield, in a sandy Ferralsol from Bahia, Brazil. The experimental design was randomized blocks, with four replicates. Soil samples were collected after five years of cotton, soybean and maize monocropping under heavy disk harrow and leveling harrow (conventional tillage), and of crop rotation of cotton, soybean and maize with green manure or cover crop (no-tillage). Additional samples were collected from a non-cultivated site (Neotropical Savanna, Cerrado sensu stricto). Soil conservation practices such as no-tillage and crop rotation with cover crop and green manure favored the soil organic carbon stock at the 0-40 cm layer, with the highest values reaching 36.03 Mg ha-1. The accrued soil carbon stock under conventional tillage and monoculture of cotton, maize and soybean was lower than under no-tillage, which ranged from 30.9 to 54.9 %, with the soil organic carbon stock increasing at the annual rate of 2.36 Mg ha-1 during five years. The no-tillage, with the soybean-maize-cotton rotation, in combination with cover crop and green manure, increased the cotton and soybean yields, with a simultaneous organic carbon accumulation in the sandy soil.
RESUMO: Mudanças no estoque de carbono orgânico e produtividade de culturas em solo arenoso tropical sob sistemas de produção de grãos-algodão em sequeiro na Bahia, Brasil. A maioria dos estudos sobre mudanças no estoque de carbono orgânico do solo no bioma Cerrado está relacionada a dados coletados em Latossolos argilosos ou sob diferentes usos da terra, como se estivessem em equilíbrio. Objetivou-se avaliar os efeitos de tipos de preparo do solo e de sequência de culturas sobre o estoque de carbono orgânico do solo e a produtividade das culturas, em Latossolo arenoso, na Bahia. O delineamento experimental foi o de blocos casualizados, com quatro repetições. Amostras de solo foram coletadas após cinco anos de monocultivo de algodão, soja e milho e de uso de grade de discos pesada e grade niveladora (preparo convencional), e de rotação das culturas do algodão, soja e milho com adubo verde ou planta de cobertura (plantio direto). Amostras adicionais foram coletadas em área não cultivada (Cerrado sensu stricto). Práticas de conservação do solo como o não revolvimento e rotação de culturas com planta de cobertura e adubo verde favoreceram o estoque de carbono orgânico do solo na camada de 0-40 cm, com os maiores valores atingindo 36,03 Mg ha-1. O acúmulo de carbono no solo sob preparo convencional e monocultivo de algodão, milho e soja foi menor do que sob plantio direto, que variou de 30,9 a 54,9 %, com o estoque no plantio direto aumentando à taxa anual de 2,36 Mg ha-1 durante cinco anos. O plantio direto, com a rotação soja-milho-algodão, combinada com planta de cobertura e adubo verde, aumentou a produtividade do algodão e da soja e acumulou carbono orgânico no solo arenoso.
