Abstract: The authors tried to establish the cost of garlic production, and the rates of utilization of the production factors, such as land, money invested, and labor, in the counties of Picos and Bocaina, in the State of Piauí. The data were collected using ";registration booklets” which were annotated daily by seven ";typical producers” who had been chosen for the study. The production cost per hectare, obtained through adding the expenses in money, calculated expenses, and retribution to production factors, was Cr$ 34,098.59, while the gross income per hectare was Cr$ 22,191.09. Labor costs were responsible for 58.03% of total cost. Man-hours for irrigation represented 29.54% of labor costs. The data presented show that the cultivation of garlic with the present technology is unfeasible economically. No estudo, realizado nos municípios de Picos e Bocaina (PI), procurou-se determinar o custo de produ o do alho e os índices de utiliza o dos fatores terra, capital e m o-de-obra. Os dados foram coletados através de “cadernos de registro” preenchidos diariamente por 7 produtores "típicos”, selecionados para o estudo. O custo de produ o por hectare, obtido pelo somatório das despesas em dinheiro, despesas calculadas e retribui o aos fatores de produ o foi de Cr$ 34.098,59, enquanto a renda bruta por hectare foi de Cr$ 22.191,09. A despesa com m o-de-obra é responsável por 58,03% do custo total. A irriga o participa com 29,54% do custo da m o-de-obra. Os dados apontados mostram que a cultura do alho com a tecnologia atualmente utilizada é uma atividade altamente deficitária.

Abstract: Objetivando avaliar a influência de diversos substratos no desenvolvimento de mudas de maracujazeiro-azedo, conduziu-se um experimento em casa de vegeta o da Emprapa Cerrados. Utilizou-se o delineamento experimental de blocos casualizados, em esquema fatorial 2 x 4 x 3 x 2, totalizando 48 tratamentos, 18 plantas úteis por parcela e 4 repeti es. Os tratamentos constituíram-se das combina es de: dois substratos comerciais (PlantmaxR -- à base de vermiculita mais casca de Pinus sp e VermiculitaR); três fontes organicas (f.o.) (húmus, esterco de curral e NutriplantaR (produto à base de bactérias) e ausência de f.o., na propor o de 3:1 do substrato básico para a f.o.); duas formula es de adubo [OsmocoteR na fórmula 14-14-14 (produto de lenta libera o de nutrientes) e 4-14-8 (de libera o normal)], além da ausência de adubo; e Glomus etunicatum, ausência e presen a. O substrato comercial PlantmaxR foi superior à VermiculitaR em todas as características analisadas. Dentre as f.o., o NutriplantaR junto com o esterco proporcionaram o melhor desempenho. O OsmocoteR promoveu o maior desenvolvimento das mudas, seguido pelo 4-14-8. A presen a ou ausência de f.o. combinada com PlantmaxR praticamente n o influenciou nas características analisadas. N o se deve utilizar o Glomus etunicatum associado a PlantmaxR, devido ao alto teor de fósforo presente neste substrato.

Abstract: O pequizeiro (Caryocar spp. - Caryocaraceae) é uma planta nativa do Cerrado e da Amaz nia, cujo fruto é muito rico em óleo e proteína, e bastante apreciado pelos povos que vivem nestes ecossistemas. O objetivo desse trabalho foi avaliar o potencial de produ o do "pequizeiro-an o", (Caryocar brasiliense subsp. intermedium), em seu habitat. Foram realizadas duas prospec es botanicas na regi o Sul do Estado de Minas Gerais, em 1997 e 1998, em áreas de vegeta o de cerrado, nas proximidades do município de Ingaí-MG, onde se observou a ocorrência de pequizeiro de porte baixo. Foi observado que os frutos apresentam deiscência e grande heterogeneidade em rela o ao número de frutos/planta. Nas plantas com tronco, encontraram-se até 86 frutos/planta e, nas sem tronco, até 16 frutos/planta. A época de matura o dos frutos concentra-se nos meses de fevereiro e mar o. O fruto de cor esverdeada e polpa amarelo-alaranjada possui em média duas sementes/endocarpo, com peso médio de 8g. Em plantios realizados no Distrito Federal, foi observado que as plantas de "pequizeiro-an o", oriundas de sementes, iniciaram a frutifica o com altura de 60 cm, aos 18 a 24 meses após o plantio, evidenciando que s o também precoces. O "pequizeiro-an o" apresenta potencial para sua explora o em cultivos comerciais e em programas de melhoramento genético.

Abstract: among the climatic factors that interfere in water erosion, precipitation, expressed by the rainfall erosivity, is of great importance. therefore, its knowledge becomes fundamental for the recommendation for soil management and conservation practices that seek the reduction of water erosion. in that context, the objectives of this work were: a) to determine the rainfall erosivity and its distribution at rio doce valley, minas gerais state, for nine sub-regions, b) to estimate the monthly ei30 index in the period from 1969 to 2005 for ferros and guanh?es counties, and c) to determine the return periods of the monthly and yearly erosivity indexes. the average erosivity value obtained was 12.913 mj mm ha-1 h-1 year-1, being classified as very high. among the sub-regions, the erosivity values varied from 8.243 to 26.676 mj mm ha-1 h-1 year-1. the critical periods in relation to water erosion due to the occurrence of erosive rains are january-march and november-december, contributing with 88.6% of the annual erosivity. from april to october, the occurrence of critical erosivity practically does not exist. the estimated individual maximum values for the return periods of 1, 10, 50, and 150 years were of 5.508, 15.534, 18.110, 19.632, and 5.542, 17.653, 20.954, 22.931 mj mm ha-1 h-1 year1 for ferros and guanh?es, respectively. the determination of the erosivity values throughout the year allows to identify the months in which the risks of soil and water losses are higher, which is important for planning the conservation practices.

Abstract: the soil born diseases cause expressive losses in passion fruit crops in brazil. the use of resistant rootstocks is an alternative to control these diseases. several wild species of passifloraceae have presented resistance to soil born pathogens, but their utilization as rootstock from seeds has been limited mainly by differences of thickness between the rootstock and the graft of the commercial cultivars. these limitations could be reduced using herbaceous cuttings as rootstock. in these experiments, herbaceous cuttings has been collected from passiflora setacea (source ec-ps 1), p. nitida (source ec-pn 1), p. caerulea (source ec-pc 1), p. actinia (source ec-pa 1) and a f1 hybrid between p. setacea x p. edulis f. flavicarpa (commercial cultivars) and treated with acetic naphthalene acid (ana) at 500 mg/l and kept in moisture greenhouse. the graftings (lateral grafting) were made at 40, 55 and 70 days after the collecting and planting of the cuttings. the evaluations were made at 145 and 150 days after the cutting planting determining the percentages of living grafts and sprouting grafts and length of the sprout graft. the grafting on rooted-herbaceous cutting of p. nitida and f1 hybrid was technically viable for passion fruit-seedling production.

Abstract: Objetivou-se avaliar o efeito do diametro do caule na desidrata o, composi o química e disponibilidade de feno da Jurema preta (Mimosa tenuiflora). As plantas estavam com média de 3 metros de altura e em final de flora o. Foram selecionados caules representativos nos diametros 5, 6, 7, 8 e 9mm, os quais foram cortados, separados em caule e folhas e submetidos ao processo de desidrata o que consistiu na secagem em estufa de circula o de ar for ada a uma temperatura de 65°C até peso constante. A curva de desidrata o foi obtida em fun o dos intervalos de tempo de pesagem. Para as demais variáveis utilizou-se o delineamento inteiramente casualizado, com cinco tratamentos e cinco repeti es. A desidrata o de caule e folhas teve resposta linear com plat , maior para diametros de 5mm cuja perda foi de 0,02g de água/g matéria seca ao final de 15,84 horas no caule, e de 0,01g de água/g MS na folha a partir 13,48 horas. Os teores de proteína bruta do caule diminuíram e os de fibra em detergente neutro e fibra em detergente ácido aumentaram com o diametro do caule, mas n o houve influência na composi o química da folha. Se o objetivo for qualidade, os caules de Jurema preta devem ser cortados com diametros inferiores a 6mm; se o objetivo for quantidade o diametro deve ser de 7 a 9mm; se a finalidade for adequar qualidade e quantidade, recomenda-se cortar os caules ao atingirem 6mm de diametro. The objective of this work was to evaluate the effect of stem diameter in branch dehydration, chemical composition and hay production in Jurema preta (Mimosa tenuiflora). The selected plants were about three feet high and were in the end of blooming. Representative branches were selected with 5, 6, 7, 8 and 9 mm diameters, which were sliced and separated into stems and leaves and submitted to the dehydration process. It consisted of drying in the forced air circulation stove at a 65°C temperature until the constant weight was reached. The dehydration curve was obtained according to the weighing time intervals. The other variables used a completely randomized design with five treatments and five replications. The stem and leaves dehydration had a linear response with plateau, being greater at 5mm, with 0.02g water/g DM in the stems after 15.84 hours and 0.01g water/g DM in the leaves after 13.48 hours. The stem CP decreased and the NDF and ADF increased with the diameter of the branch, but it did not influence the leaf’s chemical composition. If the goal is branch quality in Jurema preta, they should be cut with diameters smaller than 6 mm; if the goal is quantity, w
