1. Irrigation Management in the Paricá Seedlings Development in Amazon Region
ABSTRACT Paricá is a native tree to the Amazon region recognized for several socioeconomic applications. However, there are few studies on the influence of irrigation regime in the seedling stage. Thus, the objective of the research was to evaluate the effect of water depths and irrigation frequency on the development of Paricá seedlings in the edaphoclima

2. Agronomic trait selection and pre-germinative treatments in passion fruit hybrid
ABSTRACT Seed biometry and dormancy overcoming methods should be considered in the passion fruit production chain, in the seedling production stage, because of the different characteristics that condition the seedlings. The objective of this work was to identify and correlate the main biometric characteristics between seeds and seedlings and to select the be

3. Linear relationships between biometric variables in lettuce seedlings
ABSTRACT Seedling production is an important step in growing vegetables. The study of relationships between variables has applications in practically all areas of study and is useful in identifying relationships among quality variables in vegetable seedlings. Thus, this work aims to estimate linear relationships between biometric variables in lettuce seedlin

4. Direct onion sowing under soil tillage methods
ABSTRACT Onion production is conditioned to the adopted techniques during the cultivation. Sowing depth, soil preparation and cultivars are determinant factors for productivity to be increased. Two experiments were developed, the first with the objective of evaluating the effect of sowing depths and soil preparation methods on the germination and development

5. Silicon in wheat crop under water limitation and seed tolerance to water stress during germination
ABSTRACT Water stress during wheat seed germination and seedling establishment for affect the percentage and speed of germination. Silicon (Si) is related to plant tolerance to different types of stress, then the application of this nutrient in the mother plant during seed production could contribute to the improvement of the seed quality and, consequently,

6. USE OF BENCHES WITH REFLECTIVE MATERIAL TO FAVOR PRODUCTION OF RUBBER TREE ROOTSTOCK SEEDLINGS
ABSTRACT Success in production of any perennial tree depends on the use of high-quality seedlings. This study aimed to evaluate cultivation benches with reflective material and protected environments for production of rubber tree rootstock seedlings. The experiments were conducted in two types of protected environments: 35% shading aluminized screen and 30%

7. COMPOSTING PROCESS IN THE PRODUCTION OF LETTUCE SEEDLING SUBSTRATES: EFFECT OF COVERING AND TURNING FREQUENCY
ABSTRACT The composting of waste from a broiler chicken production chain (BCPC) promotes the mitigation of environmental impacts and allows the commercialization of compost as an agricultural input. Both the characteristics and the potential for use of the final compost depends on the operational conditions during composting. The objective of this study was

8. Seed germination and dormancy break in Eragrostis polytricha, a native Brazilian grass species with potential for recovery of degraded lands
ABSTRACT Ferruginous Rocky Outcrops have high levels of species richness and endemism, but have been threatened by several anthropic actions, especially mining. Eragrostis polytricha, a common grass species in the vegetation of these outcrops, has shown promising features for use in the recovery of mining areas. However, in order to fully understand the spec

9. VITRO OF Melanoxylon brauna SCHOTT. MORPHOGENESIS: RESPONSIVENESS OF EXPLANTS TO PERMANENT AND TEMPORARY IMMERSION GROWTH REGULATORS
ABSTRACT Melanoxylon brauna is propagated by seeds, however, low yield, pest attack and short viability are problems in seedling production. In vitro cultivation is an alternative for large-scale seedling production, but studies with this species are scarce. The aim of the work was to analyze the in vitro morphogenesis of braúna. Explants after induction of

10. ORGANIC RESIDUES IN THE COMPOSITION OF SUBSTRATES ENRICHED WITH BOKASHI BIOFERTILIZER FOR THE SUSTAINABLE PRODUCTION OF Copaifera langsdorffii SEEDLINGS
ABSTRACT One of the great challenges in the post-nursery phase is to plant seedlings in the field. It is, therefore, important to produce them to a high standard of quality aiming to achieve an economically feasible and environmentally sustainable process. For this purpose, the use of organic residues in the composition of substrates, associated with biotech

11. EFFECTS OF PHOTOSELECTIVE SHADE NETS ON EARLY GROWTH OF SUGARCANE SEEDLINGS
ABSTRACT Sugarcane has a great economic interest in Brazil, so it needs technologies to increase its yield strength, especially for seedling production. This study aimed to ascertain the influence of shading nets on early growth and development of pre-sprouted sugarcane seedlings. An experiment was conducted in a protected environment, in the Rural Federal U
