-The objective of this work was to evaluate the utilization by corn plants of P from triple superphosphate fertilizer labeled with 32 P ( 32 P-TSP), and of P from soil as affected by N rates and by the green manures (GM) sunn hemp (Crotalaria juncea) and millet (Pennisetum glaucum). The experiment was carried out using pots filled with 5 kg Oxisol (Rhodic Hapludox). A completely randomized design was used, in a 4x4x2 factorial arrangement, with four replicates. The treatments were: four P rates as TSP (0, 0.175, 0.350, and 0.700 g P per pot); four N rates as urea (0, 0.75, 1.50, and 2.25 g N per pot); and sunn hemp or millet as green manure. The additions of N and P by the GM were taken into account. After grain physiologic maturation, corn dry matter, P contents, accumulated P, and P recovery in the different treatments were measured. 32 P-TSP recovery by corn increased with N increasing rates, and decreased with increasing rates of 32 P-TSP. The mineral fertilizer provides most of the accumulated P by corn plants. The recovery of 32 P-TSP by corn was 13.12% in average. The green manure species influence the assimilation of 32 P-TSP by the plants.Index terms: Zea mays, cover crop, isotopic dilution, Oxisol, radioisotope, urea. Aproveitamento do fósforo pelo milho influenciado por adubação verde, nitrogenada e fosfatadaResumo -O objetivo deste trabalho foi avaliar a utilização, pela planta de milho, do P proveniente de superfosfato triplo marcado com 32 P ( 32 P-SFT), e do P proveniente do solo influenciado por doses de N e pelos adubos verdes (AV) crotalária (Crotalaria juncea) e milheto (Pennisetum glaucum). O experimento foi realizado em vasos com 5 kg de Latossolo Vermelho distroférrico. Utilizou-se o delineamento inteiramente casualizado, em arranjo fatorial 4x4x2, com quatro repetições. Os tratamentos foram: quatro doses de P, na forma de SFT (0, 0,175, 0,350 e 0,700 g de P por vaso); quatro doses de N, na forma de ureia (0, 0,75, 1,50 e 2,25 g de N por vaso); e crotalária ou milheto, como adubo verde. Foram levadas em consideração as adições de P e N pelos AV. Após a maturação fisiológica dos grãos, foram avaliados: a produção de matéria seca de milho, o teor de P, o P acumulado e o aproveitamento de P nos diferentes tratamentos. O aproveitamento do 32 P-SFT pelo milho aumentou com o incremento da dose de N e diminuiu com o aumento da dose de 32 P-SFT. O fertilizante mineral fornece a maior parte do P acumulado nas plantas de milho. O aproveitamento do 32 P-SFT pelo milho foi de 13,12%, em média. A espécie de adubo verde influencia a assimilação de 32 P-SFT pelas plantas.Termos para indexação: Zea mays, plantas de cobertura, diluição isotópica, Latossolo, radioisótopo, ureia.

“…Therefore, forage species with high tolerance to wet soils are required in order to maximize the production in these fields. Forage legumes, which introduce nitrogen into pasture and cropping systems, are an integral component of animal feeds, and they make an important contribution to the nutritive value of pastures [2][3][4][5]. However, there are few studies on the cultivation and utilization of tropical forage legumes in drained paddy fields in southern areas of Japan [6].…”

We investigated the root distribution and nitrogen fixation activity of American jointvetch (Aeschynomene americanaL.) cv. Glenn, under waterlogging treatment. The plants were grown in pots under three different treatments: no waterlogging (control), 30 days of waterlogging (experiment 1), and 40 days of waterlogging (experiment 2). The plants were subjected to the treatments on day 14 after germination. Root dry matter (DM) weight distribution of waterlogged plants was shallower than controls after day 20 of waterlogging. Throughout the study period, the total root DM weight in waterlogged plants was similar to that in the controls. Enhanced rooting (adventitious roots) and nodule formation at the stem base were observed in waterlogged plants after day 20 of waterlogging. The average DM weight of individual nodules on the region of the stem between the soil surface and water surface of waterlogged plants was similar to that of individual taproot nodules in the controls. Waterlogged plants had slightly greater plant DM weight than the controls after 40 days of treatment. The total nitrogenase activity (TNA) of nodules and nodule DM weight were higher in waterlogged plants than in the controls. Waterlogged American jointvetch had roots with nodules both around the soil surface and in the area between the soil surface and water surface after 20 days of waterlogging, and they maintained high nitrogenase activity and net assimilation rate that resulted in an increased growth rate.

“…Thus, crops specifically grown for green manuring generally include legume species, which can supply relevant amounts of N, a major portion of which is Ndfa. A further 10-20% of N is contained in roots (Cazzato et al 2003b;Choi et al 2008;Khan et al 2002). A further 10-20% of N is contained in roots (Cazzato et al 2003b;Choi et al 2008;Khan et al 2002).…”

The book series Advances in Olericulture provides a state-of-the-art account of research in olericulture, the applied life science of production and utilization of vegetable crops. The series focuses on various aspects of vegetable science and technology covering primarily but not exclusively species where the vegetative organ is the economically important component. The series of books spans current topics from sustainable fertilization to organic production; from open field cultivation to advanced soilless growing techniques; from vegetable seed and seedling physiology to vegetable quality and safety; from environmental stresses to phyllosphere communities interaction with vegetables; from postharvest biology and technology to minimally processing of vegetables. The series is designed to present the most advanced scientific information available linking basic and applied research for serving olericulturists, research workers, teachers and advanced students.More information about this series at
