Tipificação das famílias de oito assentamentos rurais da região de Andradina (SP), com base em diferentes estratégias de produção e comercialização

This article intends to provide a typology of the families that are settled in the region of Andradina (Sao Paulo state), according to the main production and commercialization systems and to the presence (or not) of agricultural income diversification. The empiric data used to form the groups originate from socioeconomic questionnaires that had been applied to 169 families of eight rural settlements and also from 80 interviews. The groups were compared with each other, starting from the family's profile; patrimony; credit and technical support; self-consumption production; and the lot's external income. The strategy to increase the production and the productivity (dairy cattle) is limited to less than a quarter of the producers, however different strategies had been used by families, such as the diversification of the agricultural income and the direct sale to the consumer or to the retail trade. The association of the production diversification with the use, in a regular way, of differentiated channels of commercialization demonstrated a strategy capable to approximate the indicators of this type of producer comparing with those that focused on increasing the production and the productivity. This verification is important because, even though there is no necessary contradiction among both strategies, a part of the families does not have resources, infrastructure and/or technical qualification to follow the way of the productive intensification and others do not have this project as a priority.

Influência de laminas de chuva no controle de plantas daninhas, semeadas em diferentes profundidades no solo, com aplicação de herbicidas pré-emergentes

The aim of this work was to evaluate the control in pre-emergence of the weeds brachiaria grass (Brachiaria decumbens) and goosegrass (Eleusine indica) in different depths in the ground, for the oxyfluorfen and isoxaflutole herbicides, applied in pre-emergence condition and submitted of different rain blades. The experimental design was entirely at random, with four repetitions. Each set was consisted of plastic vases with substratum capacity of 4L, filled with arenaceous ground, increased of brachiaria grass and goosegrass seeds in the depths: 0,5; 1,0; 3,0; 6,0 and 9,0 cm. Doses of 37,5 g a.i. ha -1 of isoxaflutole and 720 g a.i. ha -1 of oxyfluorfen were used. The rain blades was 5, 10 and 20 mm applied with a stationary rain simulator, beyond a treatment without rain. Visual evaluations of control at 7 and 14 days had been carried through after application of the herbicides, counting of germinated plants and dry biomass of plants without application. The development of both weeds was inhibited by herbicides, reaching 100% of control, in all depth levels. The different rain blades had not influenced the control of the weeds. In the biggest depth of sowing (9,0 cm), the emergence was above 45% to B. decumbens and 36% to E. indica in treatments without herbicides application.
