Efficiency of Slow Release Fertilizers in The Production of Eucalyptus Grandis Seedlings

چکیده
Abstract Fertilization in the seedling production phase is essential to form quality seedlings. Thus, aim of this study was evaluate appropriate doses two slow-release fertilizers (SRF1 and SRF2) their nutrient leaching behavior. For this, five different were tested. 0, 2, 4, 6, 8 kg m-³. The height, stem diameter, leaf area, shoot dry mass, root system total Dickson Quality Index measured, for each variable maximum dose technical efficiency determined. In addition, evaluated electrical conductivity, over time, determinate nutrients. All variables had satisfactory growth field planting. However, SRF2 resulted greater also experienced less loss by leaching, when compared with SRF1. both could be utilized seedlings production, at 4.00

data envelopment analysis (dea) is a powerful tool for measuring relative efficiency of organizational units referred to as decision making units (dmus). in most cases dmus have network structures with internal linking activities. traditional dea models, however, consider dmus as black boxes with no regard to their linking activities and therefore do not provide decision makers with the reasons...
Growth promotion mediated by endophytic fungi in cloned seedlings of Eucalyptus grandis x Eucalyptus urophylla hybrids
Eucalyptus cultivation has expanded considerably in Brazilian systems, leading to the current search for technologies to optimize growing conditions and the production of seedlings in nurseries. Based on the understanding that the development of tree species such as Eucalyptus sp. can be influenced by endophytic fungi that act directly as plant growth-promoting species, cloned seedlings of Euca...
متن کاملNew Development In Slow-Release Fertilizers
There have been several recent developments in slow-release fertilizers. These materials supply nutrients continuously over an extended period in contrast to water soluble fertilizers which are immediately available after incorporation in moist soil. Slow-release fertilizers are not subject to rapid leaching loss and do not easily burn plants from over-application. The major need for slow relea...
