Fertility and acidity status os latossolos oxisols under pasture in the Brazilian Cerrado.
Leguminosa Estilosantes Campo grande
Tratamento de sementes de Avena sativa l. Campo Grande reduces germination and vigor, reducing the establishment of the stand of plants.
However, it is noteworthy that the species used in this study differs from the species graned by the authors mentioned and the doses of micronutrients were employed higher than those used for the same.
This effect may be the result of excess Zn added to the concentration already present on the seeds of this micronutrient, causing inhibition of root elongation Yagi et al. However, regarding evaluations carried out in greenery, just the addition of micronutrients to coating damaged emergency.
A methodology for materials deposition in layers was performed according to Xavier et al. However, after the establishment of seedlings, the micronutrients promote their development.
The brazilian cattle industry focuses, in large part, in the Cerrado, which is characterized by the presence of micro aggregates that basically are mostly acidic soil with low capacity of cationic exchange CTC and high saturation by aluminum Vendrame et al. From the data relating to abnormal seedlings AS was unable to verify the negative effect caampo the treatments Table 1.
Campo Grande em resposta ao recobrimento com zinco e boro foi o objetivo deste trabalho. According to Prado et al. In addition, the reduction in the final germination percentage observed reinforces the hypothesis of the influence exercised by these micronutrients in the water potential of the coating reducing water uptake by seeds. Campo Grande in response to coating with zinc and boron. Revestimento de sementes de milho superdoce Sh 2. Thus, with increasing salinity occurs a decrease in osmotic potential, making water absorption by the roots more difficult Amorim et al.
Among the micronutrients, boron and zinc are worth highlighting, since they are the ones that most often cause disabilities in crops in soils of the Tropics Faquin, Journal of Seed Sciencev.
Performance of rice seeds treated with zinc, boron and molybdenum. Material and Methods Commercial seed of stylosanthes cv. The doses of micronutrients were based on recommendation of Malavoltafor forage Fabaceae.
For the rest of the evaluations, the plants were kept in a greenhouse for a total period of 47 days. Revista Brasileira de Zootecniav.

The cqmpo function of zinc on the metabolism of plants is to work as an enzyme activator and component, being essential to the activity, regulation and stabilization of protein structure Dechen and Nachtigall, Effects of boron on Rhizobium -legume cell-surface interactions and nodule development.
Speeds of germination-aid selection and evaluation for seedling emergence and vigor. Plant Physiologyv. Considering that the amount of micronutrients required by plants is small, the seed coating with micronutrients is an alternative supply, as it provides a better uniformity of distribution and utilization by plant, reduces losses, offers lower cost of implementation, in addition to improving the estilosanhes and establishment of seedlings Wazilewski and Gomes, ; Farooq et al.
This is due to the use of commercial formulations, for these authors, which have a recommended dosage for frande main crops, different from this work that followed a specific recommendation to forage Fabaceae Malavolta, T1-seed not covered; T2-seeds covered only with calcium silicate; T g of boric acid and zinc sulfate 60 g.
Conclusions The covering of seeds of stylosanthes cv. On the other hand, treatment 6 T g of boric acid and zinc sulfate g. Subsequently, the aerial part was separated from the root and both were placed in paper bags and heavy in balance of precision for determination of fresh weight of the shoot SFW and root RFW in mg per plant. The information contained in the packaging of the seed lot were Gado de Corte Divulgav.
For the variable length of the shoot SL there was a positive effect of the addition of micronutrients coating Table 3. Therefore, one can infer that, again, the osmotic effect of micronutrients may have interfered in the water potential of the coating, leading to decreases in speed of water absorption, which consequently reduced the emergence of plants. It is important to emphasize the improvement of the development of plants from camop coated in relation to the control.
Growth analysis in seedlings rice in relation of the seed treatment with mineral nutrients. The best results for root fresh weight RFW and root dry weight RDW were observed for plants from the treatment 2, however, the treatments 3 and 4 with different combinations of Zn and B did not differ to RFW and treatment 3 did not differ from the 2 as the RDW Table 3.

Physiological performance of wheat seeds coated with micronutrients. Germination test – carried out according to the modification of the Rules for Seed Testing Brasil,for the number of seeds by replication, with four replications of 50 seeds each, for each treatment. As for the biometric characteristics, some treatments with addition of micronutrients proved superior to the control, in cases such as for SL, RL, LA and NN.
In the present work the negative effect in treatment 6 T g of boric acid and zinc sulfate g. In this work, a combination of shots with maximum effect on SL and RL variables was observed and then decrease with the use of a combination of higher doses of micronutrients. BRS e o crescimento inicial.
Similar results were observed by Ribeiro et al. Tratamento de sementes de milho com fontes de zinco e boro. The treatments involving the covering of seeds, regardless of the addition of Zn and B, exerted negative impact on the first count of germination FGC. The evaluations were carried out according to Brasil Cultivando o saberv. Micronutrientes na fisiologia de plantas: To the variable number of nodes NNtreatment 4 also provided the best results, and treatments 5 and 6 provided in the lowest values, demonstrating inhibitory effect of doses used in these treatments Table 3.
However, it is important to note that the doses used by authors were much smaller when compared to the ones employed in this work.
