1. FUZZY MODELING IN ORANGE PRODUCTION UNDER DIFFERENT DOSES OF SEWAGE SLUDGE AND WASTEWATER
ABSTRACT The present work aimed to develop mathematical fuzzy models to evaluate the effects of different doses of sewage sludge and irrigation with wastewater and potable water. Such models were elaborated from an experiment carried out at the Faculty of Agronomic Sciences, in the Department of Soil and Environmental Resources, from the Sao Paulo State Univ

2. Quantitative and qualitative damages of Oebalus poecilus on irrigated rice in southern Brazil
ABSTRACT Oebalus poecilus is one of the most important pests of irrigated rice in Brazil. However, the impact of this species on the cultivar IRGA 424 RI, which is the most used, is unknown. Hence, the objective of this work is to evaluate the damage caused by O. poecilus on cv IRGA 424 RI. Panicles of this cultivar were infested for seven days at the R5 sta

3. Efeito dos Herbicidas no Rendimento e nos Componentes de Rendimento do Milho Híbrido (Zea mays)
RESUMO A cultura do milho (Zea mays) está enfrentando muitos problemas com diferentes pragas em toda a Ásia, incluindo o Paquistão. A infestação de plantas daninhas é uma das pragas graves que muito diminuiu a produtividade de grãos nessa cultura. Na província de Khyber Pakhtunkhwa, no Paquistão, a tendência para o cultivo de milho híbrido está c

4. Performance and serum cortisol concentration in Santa Inês lambs under different suckling schemes
ABSTRACT The objective of this study was to examine the effects of suckling schemes (continued, controlled, and total separation) and the type of pregnancy on performance and serum cortisol concentration in lambs. A total of 29 Santa Inês ewes and 40 lambs were used, and the randomized block design was applied in a split-plot scheme with a 3 × 2 factorial

5. APLICAÇÃO DE FUNGICIDAS EM DIFERENTES ESTÁDIOS FENOLÓGICOS DA CULTURA DO MILHO (Zea mays) NO CONTROLE DE DOENÇAS
The objective of this study was to evaluate the effects of application timing of fungicides epoxiconazole + pyraclostrobin and azoxystrobin + cyproconazole in corn in the control of Phaeosphaeria leaf spot (Phaeosphaeria maydis), rust (Puccinia sorghi), Cercospora leaf spot (Cercospora zea-maydis), stain Diplodia (Diplodia macrospora) and stem rot. Three exp

6. Ativação de genes apoptóticos no bloqueio do desenvolvimento em embriões bovinos / Activation of apoptotic genes at developmental block in bovine embryo development
Maternal-zygotic transition is a complex phenomenon characterized by the initiation of transcription in the embryo and the transition of maternal mRNA with embryonic mRNA. It is believed that the mRNAs and proteins synthethized by the oocyte during its growth and final maturation allow the zygote to develop during the early stages of embryo development up to

7. AcÃmulo de nutrientes em copo-de-leite em fase inicial de cultivo / AcÃmulo de nutrientes em copo-de-leite em fase inicial de cultivo / Nutrient accumulation in calla lily in its initial cropping stage / Nutrient accumulation in calla lily in its initial cropping stage
Calla lily cropping presents an important role in floriculture, but the knowledge of nutrient absorption and accumulation in the different plant developmental stages or the nutrient requirement are enough. This information allowed an adequate fertilizer application, according each physiological stage, resulting in a more cost-effective crop production. The o

8. Qualidade fisiolÃgica de sementes de soja convencional e RR associada ao conteÃdo de lignina / Physiological quality of conventional and RR soybean seeds associated with lignin content
In the latest crops, a strong and growing adherence of Brazilian farmers to RR transgenic soybean was found. Nevertheless, the hypothesis has been raised that these soybean cultivars are presenting differential hypotheses concerning the lignin contents in the plant, when compared with conventional cultivars. Such a variation could be occurring not only in th

9. Evapotranspiration of lettuce inside or outside a greenhouse / Evapotranspiração da cultura da alface dentro e fora de ambiente protegido
This work was carried out at the Irrigation and Drainage Experimental Station of the Federal University of Viçosa, in Viçosa, Minas Gerais state, Brazil, from December 2007 to January 2008, cultivating Lettuce (Lactuca sativa L.) cultivar Regina, under two experimental conditions as: inside and outside a greenhouse. We aimed to a) determine the crop evapot

10. Experimental clipping of Chromolaena pungens (Asteraceae) and its multitrophic effects / Poda experimental de Chromolaena pungens (Asteraceae) e seus efeitos multitroficos
Natural or human-induced disturbances may promote plant phenotypic modifications, developmental and phenological changes which, in turn, may influence herbivores, predators and pollinators. Abiotic factors, especially nutrient availability, may also influence plant recovery. In this study, we evaluated plant regrowth and arthropod responses to experimental c

11. Bloqueio da fosforilação oxidativa no cultivo de embriões bovinos / Oxidative phosphorylation blockage of bovine culture embryos
Although in vitro embryo production has been improved in the last 2 decades, about 60% of the oocytes do not reach the blastocyst stage and embryo quality is very variable when compared with in vivo produced embryo. This developmental block can be affected by inorganic ions, buffers, aminoacids and gaseous atmosphere composition. The knowledge that there inf

12. Performance of inbred and outbred Eucalyptus spp. clones in the nursery and in the field. / ComparaÃÃo do desempenho no viveiro e no campo dos descendentes de clones de Eucalyptus spp. autofecundadados e cruzados
Inbred and outbred Eucalyptus clones were assessed aiming to check a possible loss of vigor in the initial germination phases and growing in the nursery and in the field. It was also verified in the field the frequency of abnormal plants, with reduced growing and wrinkled leaves. A morphological or molecular character was searched in the nursery, which would
