27. Cultivos consorciados entre alface, cenoura, manjericão e melissa
The aim of this work was to evaluate the production of phytomass and essential oil of balm (Melissa officinalis L.) and basil (Ocimum basilicum L.) in intercropped cultive. The consorted experiment was carried out from May to October of the year 2008. The experimental delimitation was randomized blocks was consisted by seven treatments and five replications.

28. Forage and sugar-ethanol sector varieties of sugarcane at different spacing and nitrogen fertilization / Variedades de cana forrageira e sucroalcooleira em diferentes espaçamentos e adubação nitrogenada
This paper objective is to evaluate the phytomass productivity and bromatologychal attributes of two sugarcane varieties, recommended for animal feed and for sugar-ethanol sector production, planted at two inter-row spacings and submitted to nitrogen fertilization. The experiment was conducted in Presidente Prudente-SP. The experimental design was in split-p

29. SEEDLING POSITIONS ON POLYESTYRENE TRAYS AND VARIABIBLITY PRODUCTION OF LETTUCE / POSIÇÕES DE MUDAS EM BANDEJAS DE POLIESTIRENO E VARIABILIDADE NA PRODUÇÃO DE ALFACE
The scientific development has the aim of executing experiments with such quality so that obtained results are accepted and recommended. The quality of an experiment can be described through statistics, ascribing it reliance on the obtained data, being the experimental error one of the parameters the evaluations of such quality. Therefore, the present work a

31. Análises ecológicas e sensoriamento remoto aplicados à estimativa de fitomassa de cerrado na Estação Ecológica de Assis, SP / Ecological and remote sensing analyses applied to estimate the cerrado phytomass in the Assis Ecological Station, São Paulo state, Brazil
Ainda que o conhecimento sobre a flora e a ecologia do cerrado tenha sido consideravelmente ampliado nas últimas décadas, persistem dificuldades relacionadas com a caracterização estrutural das fitofisionomias e pouco se sabe sobre as transformações fisionômicas que ocorrem nesta vegetação ao longo do tempo em áreas protegidas. Adicionalmente, medi

32. EQUAÇÕES DE ESTIMATIVA DO CRESCIMENTO DO SISTEMA RADICULAR E PRODUÇÃO DE FITOMASSA DE ALFACE HIDROPÔNICA
Modelling is a technique that can be used to understand interactions between plant and environment, such as hydroponic growth dynamics. The study objective was to adjust models to estimate hydroponic lettuce growth, with emphasis on root system, the plants ware produced under different irrigations intervals. It was also verified the dynamics of interaction b

33. CASCA DE ARROZ E ESTERCO BOVINO PARA A MULTIPLICAÇÃO DE MINHOCAS E PRODUÇÃO DE MUDAS DE ALFACE, TOMATE E BOCA-DELEÃO / RICE HUSK AND CATTLE MANURE TO EARTHWORMS MULTIPLICATION AND PRODUCTION OF LETTUCE, TOMATO AND SNAPDRAGON
The earthworms are organisms of the edaphic fauna with great capacity of transformation of organic residues with stabled composting. The potential of these organisms have the advantage in the earthworm-breeding, seeking the humus production as organic fertilizer, and earthworms biomass, as food for several animals. However, many organic residues are not ofte

34. Eficiência agronômica das adubações nitrogenadas de plantio e após o primeiro corte avaliada na primeira soca da cana-de-açúcar / Agronomic efficiency of nitrogen fertilization at planting and after the first harvest, evaluated during the first sugarcane ratoon cultivation
Renewable energy sources will gradually replace non-renewable sources due to economic sustainability reasons and to the rational use of natural resources. Consequently, this study aimed to investigate sugarcane nitrogen fertilization in detail, which may help the country to become a world model in the production and use of renewable biofuels. The current kno

35. Análise de crescimento e produtividade de duas variedades de cana-de-açúcar (Saccharum spp) influenciadas por doses de fósforo
The knowledge of the leaf area is required every time the sugarcane is subjected to evaluation in which different varieties are compared or submitted to different environmental conditions, managements or fertilizations, therefore evidently showing alteration in dimensions of the plant leaves, so affecting the photosynthetic process. Although the higher breat

36. FREQÜÊNCIA DE AMOSTRAGEM DE PLANTAS DE ALFACE HIDROPÔNICA PARA AJUSTE DE CURVAS DE CRESCIMENTO / HIDROPONIC LETTUCE SAMPLING FREQUENCY TO ADJUST GROWTH CURVES
In order to construct growth curves is necessary a sequence of many samples taken during lettuce growth period. However, mainly when the trial is made in a controlled environment, sampling frequency is limited. This work was carried out with the aim to reduce sampling destruction effect without change the result precision. Two field trials were made in a con
