NITROGEN, SULFUR, MICRONUTRIENTS AND INOCULANT IN THE CULTIVATION OF IRRIGATED BEANS IN MATO GROSSO

This study to evaluate the effects of nitrogen (sources and doses), sulfur, micronutrients and inoculant in the common bean BRS Valente cultivar on winter irrigated crop because in this situation the wrong dose of N at seeding may cause immobilization of the nutrient in the soil and temporary deficiency of N in bean. The experiment took place in 2011, in the city of Sinop – MT, JF farm in the experimental design was randomized blocks with four replications and twelve treatments combining N rates up to 160 kg ha-1, sulfur and inoculation. The following characteristics were evaluated: plant height, height of the first pod, number of seeds per pod, number of pods per plant, 100-seed weight, grain yield in kg ha-1, nitrogen sufficiency index and SPAD index, nitrogen contents in leaf, seeds and plant, nitrogen use efficiency and Pearson correlation. Most variables were influenced by N applications and the highest values were verified in the dose of 160 kg ha-1. The bean yield presented positive and significant correlation with most of the evaluated characteristics and was influenced by nitrogen addition in the system, being the best yield within the highest dose of nitrogen (3262 kg ha-1). Inoculation along with cobalt, molybdenum and 40 kg ha-1 of nitrogen increased yield in comparison with absence of N

Match sources of manure in corrective land rice high in first year of culture

The objective was to evaluate the effect of phosphorus sources as a partial corrective fertilization and maintenance in upland rice cultivation. The experiment was conducted in the municipality of Alta Floresta/MT in crop year 2007/08, using the experimental design of randomized blocks with five treatments (control, simple superphosphate, triple superphosphate, Arad reactive rock phosphate and bone meal), and four replications. The following characteristics were evaluated: plant height, stem diameter, tiller number per meter, panicle number per m2, Internode length, number of grains per panicle, percentage of filled grains, voids, weight of 100 grains, return on beans, whole grain yield and productivity. Applying phosphorus influenced most of the morphological characteristics of the rice, except the stem diameter and length of the internode. There was influence of phosphate sources for the number of grains per panicle and productivity and that the two variables for the treatments with superphosphate and triple superphosphate were higher than the control. The use of triple superphosphate provided greater productivity and higher economic return in the first year of cultivation

Estudo morfológico de superfícies ósseas após secção por pontas diamantadas ou laser de érbio: YAG Morphological evaluation of bone surfaces after sectioning with diamond points or erbium: YAG laser

O objetivo deste trabalho foi analisar morfologicamente as superfícies ósseas resultantes da secção por pontas diamantadas ou por laser de érbio:YAG. Cinco ratos (Rattus norvegicus albinus foram sacrificados por dose letal de fenobarbital. Após a execução deste procedimento, os ossos predeterminados foram submetidos à secção por pontas diamantadas ou por laser de érbio:YAG em uma energia de 300 mJ por pulso e taxa de repetição de 2 Hz. As amostras foram submetidas a análise em microscópio eletrônico de varredura, revelando a existência de um padrão para as secções obtidas com cada instrumento, sendo verificada uma superfície mais regular nas amostras seccionadas com o laser de érbio:YAG. Em aumentos da ordem de 3000 vezes, pode-se observar indícios de fusão e seqüente solidificação das superfícies seccionadas por meio do laser de érbio:YAG. Conclui-se que o laser de érbio:YAG foi eficaz na remoção de tecido ósseo, mas que, nos parâmetros utilizados neste estudo, foi responsável por alterações morfológicas sugestivas de significativo aumento de temperatura, não devendo ser indicado, nestas condições, para a execução de secções ósseas.<br>The purpose of this study was to analyze bone surfaces cut by Er:YAG laser or by diamond points. Five male rats (Rattus norvegicus albinus) were killed by lethal dose of phenobarbital, and selected bones were cut by Er:YAG laser at 300 mJ and 2 Hz, or by diamond points. The samples were submitted to evaluation through SEM at standard magnifications. By analyzing the surfaces, the authors could observe a pattern for each group, with a smoother surface in the laser cut group than in the diamond cut group. In higher magnifications, the images suggest melting and solidifying in the laser group. The authors conclude that the laser was effective in bone cutting. However, it was responsible for morphological changes that suggest a significant temperature increase
