Semiarid soils may be poor in organic carbon, a necessary source of energy for soil microorganisms that affect plant growth. Although the addition carbon improve chemical characteristics, concentration humic compounds component vary and composition. We evaluated effect two sources on dystrophic yellow Oxisol cultivated with passion fruit ( Passiflora edulis Sims f. ) irrigated saline water during severe drought Brazilian semiarid region. Soil fertility was seasons. A bovine biofertilizer an...

Four feeders prepared with different levels sucrose (0%, 25%, 50% 75%), were arranged on sawhorses placed next hives Spinipes. distanced from hive each 10 meters until 100 away. Each distance number visitors counted hourly. Climatic variables...
O Pico do Jabre é um patrimônio natural e cultural com alto potencial turístico para o desenvolvimento socioeconômico da região imediata de Patos embora seja considerado uma das mais importantes áreas preservação estado Paraíba, os trabalhos sobre suas características geomorfológicas pedológicas dispostos na literatura não contemplam abordagem holística que possa reportar compreensão parte gênese sua paisagem. Este estudo realizou a caracterização solo-paisagem Parque Estadual Jabre-PB. Para...
Arbuscular mycorrhizal fungi are widespread in nature, however, their distribution the soil is uneven, being influenced by several environmental factors. This study aimed to determine species richness and relative identification of native AMFs evaluate effect annual seasonality on arbuscular present four soils representating state Paraiba (Ultisol, Oxisol, Alfisol, Entisol). Six samples each were randomly collected at 0–5 cm depth seasons, with spores extracted, counted taxonomically...
O Feijão-caupi é uma importante fonte de insumo alimentício global nos últimos anos, contribuindo sob a excelente capacidade nutrientes composto por proteínas, carboidratos, fibras, vitaminas e minerais. Logo, o objetivo deste trabalho foi avaliar as características agronômicas cultivares feijão-caupi implantadas no município Esperança-PB. Utilizou-se delineamento experimental blocos ao acaso, com 3 4 parcelas subdivididas, sendo avaliadas 20 plantas cada parcela, totalizando 120 amostras....
This article addresses the project of an Interdisciplinary Workshop, AGROTEC, and implementation sensory garden at ECIT Riachão do Poço, in Paraíba, as interdisciplinary learning tool for high school technical students agriculture, including topics bioresource technology. The municipality located state with a semi-arid tropical climate, is rich agricultural practices. objective Technical Course Agriculture seeks to promote comprehensive contextualized education. workshop aimed integrate...
The Moringa oleifera Lam. it is a perennial, arboreal species, rapidly growing, resistant to drought and with leaves, flowers edible fruits. With this research the objective evaluate effect of different substrates in emergence development seedlings Moringa. experiment was carried out at Plant Ecology Laboratory Department Phytotechnics Environmental Sciences, Center for Agricultural Federal University Paraíba. experimental desing completely randomized, eight treatments T1= sand washed...
In this research we evaluated the phenology of melon flowering (Cucumis melo L.) and diversity floral visitors in geographical conditions semi-arid climate Northeast Brazil, during wet dry seasons. The was by recording number flowers produced/plant/day from 30 plants, insects that visited were recorded following three methods: visual counts, sweep collection counting identification, observe count visits to plants (n = 30) first 45 minutes each hour. This study reports pollinators located a...
