1. Modelagem da dinâmica da água e do potássio na irrigação por gotejamento superficial. / Dynamics of water and potassium modeling under superficial trickle irrigation.
The technique of fertigation application is winning acceptance, mainly in trickle irrigation, due to the advantages that it presents as the possibility of controlling the nutrition of the plants, as the case of the potassium, that is one of the most used fertilizers. However, the description of the transport of water and solute under real conditions presents

2. Doses de N e K aplicados via fertirrigação na cultura da roseira (Rosa sp.) em ambiente protegido. / Levels of n and k applied by fertigation on rose (rosa sp.) crop in a protected environment.
The rose plant fertigation is a technique quite useful by flowers growers. The nitrogen and the potassium are the most required nutrients in the distinct crop phases, where the application of correct amounts increases the yield and flower quality. A study was carried out under protected environment conditions, at the experimental area of the Department of Ru

3. Resposta do maracujazeiro amarelo (Passiflora edulis Sins var. flavicarpa Deg) a lâminas de irrigação e doses de adubação potássica. / Passion fruit (Passiflora edulis Sins var. flavicarpa Deg.) response to irrigation water depths and potassium levels.
To study the effects of irrigation water depths and potassium levels applied by drip fertigation on the development, yield and fruit quality of yellow passion fruit (Passiflora edulis Sins var. flavicarpa Deg) a trial was carried out from May 2000 to May 2001 in the experimental area of the Department of Rural Engineering of ESALQ/USP, Piracicaba, São Paulo

4. Avaliação da infestação de insetos-praga associados à batata (Solanum tuberosum L.) sob efeito de nutrientes nitrogenados e potássicos e teores acumulados de aminoácidos livres nas cultivares Achat e Monalisa
Evaluation of insect-pest infestation associated to potato (Solanum tuberosum L.) under effect of nitrogen and potassium fertilizers and the accumulated amount of free aminoacids in Achat and Monalisa cultivars. The objective of this work was to evaluate the occurence of insect-pests on potato plants influenced by dosages of nitrogen and potassium accumulate
