| SIMPÓSIO SOBRE O CERRADO, 8.; INTERNATIONAL SYMPOSIUM ON TROPICAL SAVANNAS, 1., 1996, Brasilia, DF.. |
| O Brasil e um dos paises com maior diversidade genetica, respondendo por cerca de 30% das plantas e especies animais que ocorrem no mundo. Dentre os diferentes biomas brasileiros, os Cerrados, com seus 207 milhoes de hectares, apresenta uma grande diversidade faunistica e floristica em suas diferentes fisionomias vegetais. Ate meados deste seculo esta regiao era considerada como marginal para producao agricola, no entanto, devido ao desenvolvimento da pesquisa e de tecnologias agricolas que viabilizaram sua utilizacao em bases economicas, hoje ela e responsavel pela producao de cerca de 35% de graos e carnes do pais. O modelo de ocupacao da terra utilizado, baseado no uso intensivo de insumos e maquinas pesadas, se de um lado, no ultimos vinte anos,... |

| The aim of this study was to calibrate the CENTURY, APSIM and NDICEA simulation models for estimating decomposition and N mineralization rates of plant organic materials (Arachis pintoi, Calopogonium mucunoides, Stizolobium aterrimum, Stylosanthes guyanensis) for 360 days in the Atlantic rainforest bioma of Brazil. The models´ default settings overestimated the decomposition and N-mineralization of plant residues, underlining the fact that the models must be calibrated for use under tropical conditions. For example, the APSIM model simulated the decomposition of the Stizolobium aterrimum and Calopogonium mucunoides residues with an error rate of 37.62 and 48.23 %, respectively, by comparison with the observed data, and was the least accurate model in the... |

| "CGPRT Crops in the Philippines: A Statistical Profile, 1990-1999" is the eighth in the series of the CGPRT Centre's publications providing specific and wide-ranging agricultural data focusing on coarse grains, pulses, roots and tuber (CGPRT) crops in Asia. An earlier series was published in January 1992 in collaboration with the Philippine Council for Agriculture, Forestry and Natural Resources Research and Development (PCARRD) covering the period 1960-1990. In keeping pace with the previous publication, this updated volume covers eight crops: corn (maize), mungbean, soybean, groundnut, cassava, sweet potato, white potato and rice. Although not a CGPRT crop, rice is the most important crop in the Philippines in terms of area planted and production, hence... |

| Biochar can improve soil structure and water retention, enhance nutrient availability and retention, ameliorate acidity, and reduce heavy metal toxicity to plant roots. In this study, a basin experiment was conducted to investigate the effects of quail litter biochar (QLB) on the availability of Cd to physic nut (Jatropha curcas L.) plants. QLB was applied to the soil in which four new physic nut varieties (Takfa, Doi Saket, Lao, and Rayong) in factorial combinations at four levels (0, 5, 10, and 15 g kg-1 soil) to soil that contained 60.8 mg Cd kg-1. After transplanting plant height and canopy radius were measured every 2-mo and the number of leaves and branches at 6-mo, while yield components and Cd residues were measured at 8-mo intervals. The... |

| Abstract The peach tree is a temperate fruit tree propagated by grafting with the scion cultivar and the rootstock from seeds, generating low uniformity, a viable alternative is propagation by herbaceous cuttings. The objective of this study was to evaluate the performance of different genotypes of peach rootstock propagated by herbaceous cuttings. The experiment was carried out with standardized cuttings of 15 cm in length treated with 3,000 mg L-1 of IBA solution, then were transplanted into 3 L polyethylene bags. A completely randomized design with five replications was adopted, each plot consisting of three plants. Sixteen peach genotypes from UFV breeding program were tested: 713-3, 713-6, 713-7, 713-10, 813-2, 813-3, 813-5, 813-15, 913-3, 913-6,... |

| A regiao do Cerrado com 205 milhoes de hectares, em menos de tres decadas, transformou-se na principal area agricola do Brasil. Essa rapida transformacao foi possivel devido a investimentos expressivos do governo em infra-estrutura e programas de desenvolvimento para ocupar esse ecossistema aliados aos avancos tecnologicos em manejo de solo e selecao de cultivares adaptadas as condicoes edafoclimaticas da regiao. O crescimento da agricultura nessa regiao teve influencia positiva na geracao de riquezas e de empregos. No entanto, tem gerado impactos ambientais negativos como: compactacao, erosao e perda de materia organica do solo nos sistemas de cultivos anuais. Ao mesmo tempo, os problemas de degradacao de pastagens agravaram-se, sendo especialmente... |
