It was evaluated the development of "Baru" seedlings (DipteryxalataVog.) in pots under three levels of shading and four textural classes, from March to october 2010, in Campo Grande-MS. Treatments consisted of 0%, 30% and 50% levels of shade and sandy, medium clay and heavy clay soil. The experimental design was randomized blocks in split plots with repeated measures. It was used three replicates of ten plants per plot. The shading levels corresponded to the treatments and the different textural classes to the subplot. Plant height, leaf number and stem diameter were evaluated 15 days after emergence (DAE) to 195 DAE. Survival rate, leaf area and dry mass of the leaf, the stem and the roots were also estimated at 195 DAE. Higher values were observed in height and leaf area under shading condition. Plant height was 32.09 cm and 31.21 cm plant-1, leaf area was 639.24 cm 2 and 580.49 cm2 for 50% and 30% shade levels respectively. In clay soil the values were higher in most traits followed by soil with loamy soil. The highest yield of dry mass of leaf was in the clayey soil with an average of 7.28 g plant-1.The percentage of seedling survival in sandy soil was lower than in the others. There was an interaction between levels of shading and texture classes of soil on dry mass of the roots which was higher (1.43 g kg-1 soil) on the loamy soil at 50% shading. "Baru" seedlings reached measurements of height and diameter suitable for all levels of shading and textural classes. Source

This paper reports an occurrence of Meloidogyne enterolobii (syn. M. mayaguensis) in the State of Mato Grosso do Sul, on guava (Psidium guajava), cv. Novo Milênio. The nematode was characterized and identified using esterase (Est) isozyme phenotype (Est M2, Rm: 0.7 e 0.9). Source

This work aimed to evaluate the behavior of four banana genotypes: FHIA 1,FHIA 18 hybrids and Caipira and Prata-Anã cultivars during the first production cycle under the environmental conditions of Bonito - MS. The hybrids FHIA 1 and FHIA 18 presented the highest yield with 27 and 24.5 t/ha respectively. The hybrids were statistically higher when compared with the cultivars for the characters bunch mass, number of hand, raquis mass and total mass of fruits. The hybrids and the Caipira cultivar presented similar mean for total number of fruits, with FHIA 18 presenting the highest mean of 119.30. In relation to the production cycle, the FHIA 18 hybrid and the cultivars showed the same cycle from flowering to harvest (142 days). FHIA 18 hybrid and 'Prata-Anã' presented shorter cycle up to flowering while FHIA 1 hybrid was later, presenting a shorter period from flowering to harvest (120 days). From the results obtained in this evaluation, the hybrids FHIA 1 and FHIA 18 presented larger productivity. The FHIA 18 hybrid had the lower production cycle in Bonito-MS region. Source
