O melao ( Cucumis melo L.) e uma importante hortalica cultivada no Brasil, sendo o oidio ( Sphareoteca fuliginea) capaz de reduzir sua producao. O objetivo do trabalho foi avaliar o controle do oidio do meloeiro rendilhado cultivado em casa de vegetacao com biofertilizante e soro de leite bovino em diferentes dosagens. O delineamento experimental foi em blocos ao acaso, com 8 tratamentos e 3 repeticoes. Os tratamentos foram: testemunha (sem aplicacao); aplicacao de fungicidas (fungicidas alternados - enxofre 80: 200 g ha -1 ; tiofanato metilico 700: 70 g100 L -1 de agua; azoxistrobina 50: 8 g100 L -1 de agua), biofertilizante 50 e 100% e soro de leite nas doses de 25, 50, 75 e 100%. Dentre os resultados, foi observado que o soro de leite bovino proporcionou protecao contra oidio, sendo de 30% quando comparada a testemunha e em relacao ao fungicida a melhor dose de soro proporcionou 10% mais severidade de oidio. A aplicacao de biofertilizante e doses de soro de leite bovino, menores que 100% nao proporcionaram diminuicao na severidade do oidio na cultura do melao rendilhado.
甜瓜(Cucumis melo L.)是巴西种植的一种重要蔬菜，而油菜(Sphareoteca fuliginea)能够降低其产量。本研究的目的是评价不同剂量生物肥料和牛乳清对温室栽培甜瓜油的防治效果。试验设计为随机区组，8个处理，3个重复。处理为:对照(不应用);杀菌剂的应用(交替杀菌剂-硫80:200 g ha -1;甲基噻吩酸700:70 g100 L -1水;偶氮菌酯50:8 g100 L -1水)，生物肥料50和100%，乳清剂量为25、50、75和100%。结果表明，与对照相比，牛乳清对碘的保护作用为30%，与杀菌剂相比，最佳剂量的乳清对碘的保护作用要高10%。施用生物肥料和牛乳清剂量低于100%并不能降低甜瓜培养中oidio的严重程度。

The performance of a carrot crop depends on several factors including the density of planting. The aim of this study was to evaluate the effect of different planting densities on carrot growing in length, diameter, weight per unit and produção/m 2 . The study was conducted at Farm Santo Antonio, in the municipality of SponsorshipMG in 2011. The experiment was conducted in randomized blocks with five treatments and five replications in a floor area of 25m2, with the treatment plant densities 10, 8, 6, 4 and 3 cm between plants. The spacing adopted was 25 cm. As they increased the planting density was decreased in length and root diameter and weighing. Productivity density of 8 cm between plants showed the highest mean of 6.68 kg/m 2 . The increase in the density of planting carrot results in an increase in length and root diameter and weight per unit and to a certain limit is the compensation of the total production by raising the number of plants. The best density cultivation of carrot cultivar "Brasilia", considering the quality of trade, 6 and 8 cm between plants.

The castor bean pie is a residue or byproduct of biodiesel production directly from seed (PDS). The generation of the press cake occurs in large quantities, thence the need of destination that material. To destine a residue is necessary to perform its chemical characterization. Given the above, the objective of this study was to characterize chemically the castor press cake PDS compared with castor press cake commercial, and evaluate the variability of the seeds and pie in each lot. For that, representative samples were collected and sent for analysis at an accredited laboratory. Besides, it was determined the most limiting elements and promising material, and also the variability of element contents in different lots of seeds and respective pie. The values observed were compared to the maximum allowed by legislation in the country. Sodium is the more limiting element for using the press cake as organic fertilizer, due to the harm it can cause to plants and soil. Also, the elements or substances aluminum, cadmium, iron, manganese, total phenols, and surfactants are above the maximum value permitted. The castor press cake PDS was classified as a Class II A residue.

The sunflower crop is growing on the national scene, but there are many pathogens that can become limiting for the production, among them are the gall-forming nematodes, which are spread in almost all agricultural regions of the country. This work aimed to assess the reaction of sunflower cultivars to nematodes Meloidogyne incognita race 3 and M. javanica. At 88 days after inoculation, proceeded to the evaluation considering the average number of eggs per gram of the root (MNGR), the average total number of nematode eggs per treatment and J2 (MNNOT) and numbers of eggs per treatment (MNOT) thereby determining the multiplication in relation to the initial inoculation. The okra cv. Santa Cruz (Abelmoschus esculentus (L.) Moench) and Crotalaria breviflora were used as witness of susceptibility and resistance respectively. The four cultivars behaved as hosts because they showed higher values of nematodes. The Cultivar Agrobel 960 present (MNNOT) and (MNOT) of M. javanica less than to witness and in relation to other cultivars.

The objective of this study was to determine the effects of the partial substitution of forage neutral detergent fiber (NDF) with whole or processed cottonseed NDF on feeding behavior and ruminal mat consistency of lactating Holstein cows cannulated in the rumen, which were assigned in a 6×6 Latin square design during 90 days. Two control diets were utilized, one with low (LFD = low forage diet) and another one with high (HDF = high forage diet) forage NDF (fNDF), which represented respectively the negative (16% fNDF; DBF) and positive (21% fNDF; DAF) controls. Four experimental rations were balanced to contain 16% fNDF and 5% NDF from whole or processed cottonseed. There was a reduction (P<0.05) in the times spent with rumination and mastication in the cottonseed diets compared with the 21% fNDF diet (DAF). There was no effect (P>0.05) of the partial substitution of fNDF with cottonseed NDF on ruminal mat consistency. Taking into account the feeding behavior as a criterion of evaluation, the effectiveness of cottonseed NDF was lower than the 21% fNDF diet (DAF), however, considering the ruminal mat consistency as a way of assessment, the effectiveness of cottonseed NDF was similar to the forages utilized in the present study. The ways of processing did not alter the effectiveness of cottonseed NDF.

本试验采用6×6拉丁方试验设计，研究饲粮中性洗涤纤维(NDF)部分替代全棉籽或加工棉籽洗涤纤维(NDF)对泌乳荷斯坦奶牛瘤胃喂养行为和瘤胃垫浓度的影响。采用低饲粮(LFD =低饲粮)和高饲粮(HDF =高饲粮)饲粮NDF (fNDF)两种对照饲粮，分别为负饲粮(fNDF为16%;DBF)和阳性(21% fNDF;DAF)控制。4种试验日粮分别添加16%和5%全棉籽和加工棉籽中的NDF。棉籽NDF部分替代fNDF对瘤胃垫稠度的影响显著降低(P0.05)。以取食行为为评价标准，棉籽NDF的有效性低于21% fNDF饲粮(DAF)，但以瘤胃垫稠度为评价标准，棉籽NDF的有效性与本研究使用的饲料相似。加工方式对棉籽NDF的有效性没有影响。1巴西联邦大学Goiás, Veterinária动物技术大学，Samambaia第二校区。2巴西圣保罗大学，Luiz de Queiroz高等农业大学，动物技术学系。3巴西联邦教育学院，Ciência巴西理工大学ipor校区，saída para Piranhas - ipor /GO - CEP: 76200 -000 Fone:(64) 3674-0400。*电子邮件:eduardo.carvalho@ifgoiano.edu.br。Autor para correspondência。4 AGROCRIA commercial e Indústria ltd .;5 universsidade estual de Goiás， o Luis de Montes Belos。接收日期:23/01/2014。avprovado em: 25/04/2014。m.l.m.l ima等人。科学技术，2007,01,p.129 - 139, jan/abr。2014. 130

Two control diets were utilized, one with low (LFD = low forage diet) and another one with high (HDF = high forage diet) forage NDF (fNDF), which represented respectively the negative (16% fNDF; DBF) and positive (21% fNDF; DAF) controls. Four experimental rations were balanced to contain 16% fNDF and 5% NDF from whole or processed cottonseed. There was a reduction (P<0.05) in the times spent with rumination and mastication in the cottonseed diets compared with the 21% fNDF diet (DAF). There was no effect (P>0.05) of the partial substitution of fNDF with cottonseed NDF on ruminal mat consistency. Taking into account the feeding behavior as a criterion of evaluation, the effectiveness of cottonseed NDF was lower than the 21% fNDF diet (DAF), however, considering the ruminal mat consistency as a way of assessment, the effectiveness of cottonseed NDF was similar to the forages utilized in the present study. The ways of processing did not alter the effectiveness of cottonseed NDF.
