ABSTRACT Light is one of the factors that most affect crop growth and yield. However, control light intensity difficult, because, under certain environmental conditions, energy may exceed or limit capacity plants to use it. In this sense, productive behavior plant species in shaded environments needs be known. This study aimed evaluate effect different with black shade nets [0 (full sun), 35 50%, overlap + 50% shading nets] on flowering, yield quality inflorescences Heliconia psittacorum...

Bovine manure biofertilizers can exert physical, chemical, and biological effects on the soil phytoprotective, physiological, productive actions in horticultural crops. The literature review was performed to compile information production, uses, of bovine properties plants. Biofertilizers are produced by organic components, minerals, inoculants. Among sources, is most used. fermentation water constitutes Vairo biofertilizer, employed Brazilian horticulture. With chemical enrichment this...

The identification of alternative substrates that are suitable for the production potted plants is very important. To this end, we studied influence different on growth and chrysanthemum (Dendranthema grandiflora Tzvelev cv. Funny). A completely randomized design with four treatments twelve replicates was used. Each treatment consisted following substrates: i) carbonized rice husks; ii) commercial substrate; iii) mixture vermiculite husks in a 1:1 proportion; iv) washed sand proportion....

Biofertilizers instead of synthetic chemicals are known to improve plant growth through the supply nutrients and they may help sustaining environmental health soil productivity. An experiment was carried out evaluate fruit yield macronutrient foliar contents yellow passion plants (Passiflora edulis) as a function biofertilizers nitrogen-phosphorus-potassium (N-P-K) fertilizing in Brazil (2005–2007). The experimental design randomized blocks with treatments, which were distributed factorial...

A utilização dos resíduos orgânicos na composição substratos para mudas significa uma alternativa à reciclagem desses materiais. Objetivou-se avaliar as características agronômicas de tomateiro produzidas em materiais regionais alternativos utilizados como substrato e sob adubação foliar. O experimento foi conduzido ambiente protegido no Campus da Universidade Federal do Piauí, Bom Jesus-PI. Utilizou-se o delineamento experimental inteiramente casualizado, com os tratamentos distribuídos...

The shoot maturation phase is important for growing mangoes because it precedes the floral induction, when plants are under stress caused by high temperatures and low water availability. Abiotic could be alleviated using plant biostimulant which alters phytohormone carbohydrates biosynthesis. Thus, an experiment was conducted to evaluate use a containing Ascophyllum nodosum induce of mango cv. Palmer grown in semi-arid environment. experimental design consisted randomized blocks with four...

Biofertilizers, liquid cattle manure obtained from anaerobic processes, have emerged as an important component of the integrated nutrient supply system. Thus, experiment was carried out May 2002 to February 2004 evaluate fruit quality and macronutrient foliar contents biofertilized yellow passion plants in Brazil. The experimental design randomized blocks with treatments distributed a factorial arrangement (2 × 5) referring two biofertilizers [one simple another enriched macro-...

ABSTRACT This study aimed to prospect, among the species that grow spontaneously in compacted landfills, native Caatinga plants with potential for ground cover extremely impacted areas, exposed soil. Initially, a general floristic survey was carried out four areas. To prospect species, data referring richness, coverage, and densification of herbaceous stratum were collected each area, using method plots. The selection based on species-specific characteristics: origin, plant habit, life...

This study aimed to evaluate the effect of different substrates and environmental conditions on seedling production heliconia (Heliconia psittacorum L.) in Northeastern Brazil. A completely randomized blocks design with treatments distributed a factorial arrangement (6 x 2) referring substrate compositions condition produce seedlings (open field net-house) was used, four replications. The following were tested: (i) soil + sand bovine manure (SSB); (ii) goat (SSG); (iii) decomposed buriti...

Biofertilizers are organic products usually obtained from an anaerobic process, evaluated mainly as phytoprotectors for agriculture, although they can improve fruit production. By this way, a field experiment was carried out in Remígio County, Paraiba State, Brazil, to evaluate the effects of two bovine biofertilizers on yield, medium mass and quality papaya fruits (Carica L.), ‘Baixinho de Santa Amália’ cultivar. Treatments were distributed randomized complete blocks design with three...

The propagation of ‘juçara’ and ‘açaí’ is done by seeds, but there a great desuniformity in the germination process. In this way, objective study was to verify effect temperature, mechanical scarification substrate on seed both species. Two experiments were conducted completely randomized design, with four replications each consisting 25 seeds. first 14 treatments factorial scheme 7 x 2, seven temperatures (20, 25, 30, 35, 20-30 25-35 °C natural condition), without scarification. second...

The use of shading has been widely used for production seedlings, flowers and ornamental plants, aiming to minimize the damage from excess luminosity. This research evaluated effect different shaded environments [0% (full sun); 35% 50% overlapping screens 35%+50%] on morphophysiological aspects growth Heliconia psittacorum cv. Golden Torch bihai Humilis in Bom Jesus county, Piaui state, Brazil, August, 2012 July, 2013. experiment was carried out a completely randomized design with treatments...

O manejo do substrato e da adubação é imprescindível para garantir a formação de mudas espécies florestais com qualidade que tenham êxito no estabelecimento em campo, seja fins arborização urbana, recuperação áreas degradadas, projetos reflorestamento ou madeireiros.
