| ABSTRACT There is little information about common bean fertilization in African Savannas. The objectives of this study were as follows: i) to evaluate the common bean yield potential in the environmental conditions of Lichinga, Niassa, Mozambique, and ii) to determine the common bean response to phosphorus and potassium fertilization applied together in order to verify whether the interpretation of soil analysis for the Brazilian Cerrado could be adopted for Savanna soils in Mozambique. The experimental design was a randomized block design in a 5 x 4 x 2 factorial arrangement. Treatments consisted of a combination of phosphorus doses (0, 35, 70, 140 and 280 kg ha-1 of P2O5), potassium doses (0, 50 100 and 200 kg ha-1 of K2O), and different growing seasons... |

| A utilização de gesso agrícola no sistema plantio direto (SPD) pode ser alternativa para viabilizar o cultivo do arroz de terras altas por proporcionar o carreamento de nutrientes para as camadas mais profundas e estimular o crescimento radicular. Assim, o objetivo do trabalho foi determinar o efeito do gesso agrícola aplicado em superfície do solo sem revolvimento, na altura e no acamamento de plantas, nos componentes de produção, na produtividade e na qualidade industrial de grãos de arroz. O experimento foi desenvolvido durante três safras agrícolas em condições de campo, no município de Selvíria, MS. O delineamento experimental foi em blocos completos casualizados no esquema fatorial 4 x 3, com cinco repetições. Os tratamentos constaram da combinação... |

| ABSTRACT The use of products that promote reduction of nitrogen (N) losses from the urea fertilizer can contribute to increasing its use efficiency in forage grasses. This study aimed to evaluate the effects of N sources and doses on the growth of Urochloa ruziziensis. The experiment was carried out in the growing season of 2007/2008 in Santo Antônio de Goiás-GO, in a Brazilian Oxisol. A completely randomized block was used, with four replicates in a factorial scheme, corresponding to two N sources (conventional urea and urea with urease inhibitor) and five N doses (0, 50, 100, 200 and 300 kg ha-1), divided into equal applications in five periods (Nov 14 to Dec 13, Dec 14 to Jan 12, Jan 13 to Feb 11 - rainy season, Mar 24 to Apr 22 and Jul 10 to Aug 08 -... |

| An important point in no-tillage system is the time between cover crop glyphosate desiccation and rice sowing. This study aimed to verify the effect of Brachiaria ruziziensis management time before rice sowing on rice yield and its components. The experiment was conducted under greenhouse conditions and consisted of four types of B. ruziziensis management: with Brachiaria and with herbicide (WBWH), without Brachiaria shoots and with herbicide (NBWH), without Brachiaria shoots and without herbicide (NBNH), and with Brachiaria and without herbicide (WBNH), at four times: 30, 20, 10, and 0 days, preceding the rice sowing. The amount of B. ruziziensis dry matter increased as the management was done closer to the rice sowing date. The WBWH and WBNH managements... |
