| Abstract Knowledge on the amounts of nutrients accumulated by pitaya in its different development stages allows defining the periods in which the essential elements are most required, thus contributing to the elaboration of rational fertilization programs for the crop, reducing production costs. This study aimed to evaluate the growth and nutritional requirement of red pitaya, estimating the accumulation of macro and micronutrients by the plants and determining the periods in which the greatest accumulations occur, as well as the relative growth rate and the relative nutrient absorption rate. Pitaya seedlings were planted in pots containing Argissolo Vermelho-Amarelo Eutrófico (Ultisol) and grown in the open air. The experimental design was randomized... |

| Objetivou-se com este trabalho avaliar níveis e formas de aplicação de nitrogênio sobre a produtividade e a qualidade fisiológica de sementes de feijão caupi. O trabalho foi desenvolvido no Campus do Pici da Universidade Federal do Ceará. As parcelas foram constituídas por seis linhas de 5 m espaçadas em 0,5 m, sendo a área útil às quatro linhas centrais desprezando-se 0,5 m em ambas as extremidades. A densidade de semeadura foi de 12 sementes m-1. Nessa etapa obteve-se a produtividade de sementes. A qualidade fisiológica das sementes foi avaliada a partir dos testes: germinação, primeira contagem, emergência de plântulas, índice de velocidade de emergência e, massa seca da parte aérea. Os tratamentos consistiram na ausência de adubação nitrogenada e nas... |

| Sesame (Sesamum indicum L.) is one of the oldest oilseed plants used by man, and has great economic potential due to the possibilities for its exploitation in both the domestic and international markets. The objective of this work was to monitor the viability of sesame seeds stored in different environments and packaging, with a view to their conservation. The seeds were packed into paper bags, multiwall paper, black polyethylene and PETE bottles, and stored for a period of 12 months in different environments: dry cold room (10 °C and 55% RH), natural environment (30-32 °C and 75% RH), refrigerator (4 °C and 38-43% RH) and freezer (-20 °C). Every three months the water content of the seeds was determined and germination, accelerated ageing, speed of... |

| The sunflower is among the top five crops in the world for the production of edible vegetable oil. The species displays rustic behavior, with an excellent edaphic and climatic adaptability index, being able to be cultivated throughout Brazil. Seed quality is the key to increasing production and productivity in the sunflower. The objective of this work was to monitor the viability of sunflower seeds with a view to their conservation when stored in different environments and packaging. The seeds were packed in paper bags, multilayered paper, black polyethylene and PET bottles; and stored for a period of twelve months in the following environments: dry cold room (10 ºC and 55% RH), the ambient conditions of Fortaleza, Ceará, Brazil (30-32 ºC and 75% RH),... |
