The production of passion fruit seedlings constitutes one of the important stages of the production system and the importance of substrate for the seedlings growth and plant performance in the field. Therefore, the objective of this study was to evaluate the effects of different composting organic wastes in the substrate composition for production of yellow passion fruit seedlings. The experiment had been conducted in the Centre of Human, Social and Agricultural Sciences at The Federal University of Paraíba. The experimental design was randomized block design, with six treatments, goat composite + soil (CCP+S), poultry composite + soil (AC+S), bovine composite + soil (CB+S), rabbit composite + soil (CCO+S), earthworm humus + soil (MH + S), and soil (S) and S in the ratio of 2:1 (v/v) and five repetitions. Emergency speed index, emergency percentage, stem diameter, seedling height, leaf number, root length, fresh root mass, shoots fresh mass, total of fresh mass, dry mass of root, dry mass of branches, total dry mass, chlorophyll a, b and total, and Dickson quality index were assessed. The compounds in the constitution of substrates exerted significant effect on the characteristics evaluated in the passion fruit, which may be related to the availability of nutrients to the substrate. The substrates containing CCP+S and CCO+S provided better growth, chlorophyll contents and quality of "Serra" yellow passion fruit seedlings.

Beans are a the major component in the Brazilian diet population, mainly in the northeast of Brazil, though yield is considered low due to the low technological content that is conducted in most producing regions, making it necessary for fertilizations to increase this feature. Considering the above, this study aimed to evaluate growth, chlorophyll index and the production of cowpea bean and common bean under different fertilizations. The experiment had been conducted in the Centre of Human, Social and Agricultural Sciences at The Federal University of Paraíba. The experimental design was a randomized block in factorial arrangement 2 × 4 with seven repetitions. The treatments consisted of two-bean varieties (Phaseolus vulgaris L. and Vigna unguiculata L.) and four fertilization (Leaf biofertilizer, organic compost made with goat manure, mineral fertilization and a without fertilizer treatment). The variables analyzed was growth, chlorophyll index and bean production. The bean cultivar Sempre Verde obtained higher growth and chlorophyll index a, b and total in relation Carioca. Fertilization with organic compost provided higher productivity of bean cultivars. The organic compost may be indicated as fertilizer alternative to the bean in the Paraíba swamp region.
