O nitrogênio e o potássio são os elementos mais absorvidos e exportados pelo feijoeiro, sendo a adubação mineral entre os produtores bastante variável quanto as doses aplicadas. Este trabalho avalia os efeitos de doses de N (0, 60, 80, 100 e 120 kg ha-1) e K2O (0, 60 e 120 kg ha-1) no desenvolvimento do feijoeiro, por meio do número de unidades estruturais, peso de material fresco e seco, e a concentração de macronutrientes no florescimento. O experimento foi realizado em Botucatu, SP., em túnel plástico, utilizando-se a cultivar 'Pérola'. Duas plantas foram cultivadas em vasos de 15 L, preenchidos com terra de Latossolo Vermelho Distrófico típico, textura média, por 50 dias. As doses de NK foram parceladas em cobertura aos 20 e 40 dias após semeadura. As variáveis estudadas foram influenciadas pela interação entre as doses de N e K. A adubação parcelada com N via solo, independentemente das doses utilizadas ou da fertilização com K, aumenta a produção de matéria seca sem interferir nos teores de N da parte aérea do feijoeiro, assim como os de K, Ca e Mg. A omissão de N em cobertura reduz o teor de clorofila, diminuindo a produção de matéria seca, mas não interferindo no número de flores. Os níveis de K utilizados não diminuíram os teores de Ca e Mg da planta.

In the 90, the public politics for the Brazilian rural way incorporated the territorial perspective, besides they motivate the participation and the beneficiaries collective organization. In 2003 the Food Acquisition Program (FAP) was created with the intention of guaranteeing the feeding of people in social vulnerability situation or alimentary insecurity and of providing work and income in the field through the direct buying of the agriculturists foods. In a research made in two São Paulo State's towns: Tupi Paulista and Dracena, it was verified that the price paid to the farmers is higher to the regional average and because of this fact the participants have interest in enlarging the cultivated area and/or in diversifying the cultivations. Though, two problems were detected: 1) the reduced number of beneficiated producers; and, ii) the furtherance of the producers relatives already registered that try to increase their quota of products and the value to be received.

In the context of the project “Development and qualification of agriculturists in the use of techniques for correction of theground in agricultural assentament”, the identification of the use of agricultural techniques becomes necessary as an important tool for decision taking, mainly in regards to the public politics of Assistance Technique and Agricultural Extension (ATER). In such a way, the present study it had for objectiveto diagnosis the use of limeand fertilization techniques in these agricultural assentamentin order to identify possible public politics ATER. Of the total of boarded families, 79.89% had answered to the questionnaire elaborated for this diagnosis. The field research was carried throughapplication of questionnaire elaborated for this study and the analysis of the results divided in profile of the beneficiaries, knowledge of techniques of ground handling and agricultural use of the areas of the Projects of Assentamentfor the beneficiaries. It was concluded that even so the great majority of the beneficiaries agricultural area and farmers to be declared diligent of this information are not in coherence with the one of knowledge of the type of ground, therefore, this type of understanding of the landscape is primordial for the taking of decision with regard to the agricultural use of the ground, moreover, the access to the knowledge and use of the techniques of limeand fertilization comes diminishing in the agricultural assentamentunder validity of II National Plan of the Agrarian Reformation, what it enters in total discord with the premises of the same. It fits here to detach the importance of public politics ATERdirected these beneficiaries of the Agrarian Reformation, mainly with regard to the ground handling.
