Crescimento, fotossintese e eficiencia do uso de nitrogenio em milho, feijao e mandioca submetidos a dois niveis de N no solo

Autor: Porto, M.C.M. El-Sharkawy, Mabrouk A. Cock, James H. Hernández, A. del P. Cadena, G. de

Growth and N uptake in pot-grown maize, beans, and cassava were evaluated under 2 levels of soil N at CIAT-Palmira (Colombia). The lower amount of the element reduced its uptake by the 3 species, resulting in lower tissue concn., especially in the leaves. Under low N, DM accumulation was also red...

Nitrogen mineralization and crop uptake from surface-applied leaves of green manure species on a tropical volcanic-ash soil

Autor: Cobo Borrero, Juan G. Barrios, E. Kass, DCL Thomas, Richard J.

Leaves of nine green manure (GM) species were surface applied to a tropical volcanic-ash soil at a rate of 100 kg N ha 1 in order to evaluate their N-fertilizer value in a glasshouse experiment. GM treatments were compared to urea at two rates, 50 kg N ha 1 (FN50) and 100 kg N ha 1 (FN100), and t...

Effect of successive cuttings on uptake and partitioning of 15N among plant parts of Leucaena leucocephala

Autor: Sanginga, N. Zapata, F. Danso, S.K.A. Bowen, G.D.

We studied the effect of three successive cuttings on N uptake and fixation and N distribution in Leucaena leucocephala. Two isolines, uninoculated or inoculated with three different Rhizobium strains, were grown for 36 weeks and cut every 12 weeks. The soil was labelled with 50 ppm KNO 3 enriche...

Mulching effect of plant residues with chemically contrasting compositions on maize growth and nutrient accumulation

Autor: Tian, G. Kang, B. Brussaard, Lijbert

Effects of application of prunings of three woody species (Acioa barteri, Gliricidia sepium and Leucaena leucocephala), maize (Zea mays L.) stover and rice (Oryza sativa L.) straw as mulch on maize were studied on an Alfisol in southern Nigeria in 1990 and 1991. Maize dry matter and grain yield w...

Differences in root distribution, nutrient acquisition and nutrient utilization by tropical forage species grown in degraded hillside soil conditions

Autor: Gómez Carabali, A Rao, Idupulapati M. Ricaurte, Jaumer

Low nutrient availability, especially phosphorus (P) and nitrogen (N) supply is the major limitation to forage production in acid infertile soils of the tropics. A ﬁeld study was conducted at the farm ‘La Es- peranza’ located in Mondomo, Department of Cauca, in the coffee growing zone of Colombia...

Effects of constant and fluctuating soil temperature on growth, development and nutrient uptake of maize seedlings

Autor: Lal, R.

The effect of constant and fluctuating soil temperature and two soil moisture regimes on the growth, development, transpiration and nutrient uptake by maize seedlings was studied in a greenhouse investigation. The constant root temperatures were maintained at 30, 34, 35, 36, 37, and 38°C for both...
