1. Straw management effects on sugarcane growth, nutrient cycling and water use in the Brazilian semiarid region
ABSTRACT It was evaluated how straw management modifies the development, growth, nutrient cycling and crop water productivity of sugarcane in the semiarid region of Brazil. The experiment was carried out using two plots with 5 ha each, being one without straw on the soil surface and one with 26 Mg·ha-1 covering the soil. Sugarcane growth and development and

2. The effects of magnesium deficiency on sugar partitioning do not restrict the root growth in Eucalyptus young plants
Resumo Os sintomas da deficiência de magnésio (Mg) têm sido bem documentados em plantas cultivadas. A relação entre a deficiência de Mg, como um importante fator de estresse abiótico, e a partição do açúcares, pode restringir o crescimento das raízes e limitar o sucesso do plantio no campo. Apesar disso, os efeitos fisiológicos primários da bai

3. Partitioning and Modeling of Biomass in Caatinga Legume Seedlings in Different Water Conditions
ABSTRACT The accumulation of dry biomass, its partitioning and the adjustment of equations were assessed for the initial growth of Piptadenia stipulacea (Benth) Ducke and Anadenanthera colubrina (Vell.) Brenan under water availability variation. The experiment was conducted in pots arranged in a completely randomized design with three replicates. Water condi

4. Water relations of chives in function of salinity and circulation frequency of nutrient solutions
RESUMO O cultivo hidropônico com o uso de águas salobras, constitui-se em uma alternativa para a produção agrícola, especialmente no cultivo de hortaliças. Sendo assim, desenvolveu-se o presente trabalho com o objetivo de avaliar o consumo, eficiência e o teor de água, bem como a partição de massa seca de plantas de cebolinha (Allium schoenoprasum)

5. Phosphorus requirement and partitioning in oat cultivars
RESUMO: A adubação de reposição varia com a demanda e a partição de nutrientes, mas isso é pouco conhecido em relação as cultivares de aveia. O estudo objetivou avaliar se a demanda e a partição de fósforo (P) diferem entre cultivares de aveia-branca. As cultivares ‘UPFA ‘Ouro’, ‘UPFPS Farroupilha’, ‘IPR Afrodite’, ‘URS 21’, �

6. Root growth and carbohydrate partitioning in cotton subjected to shading in the initial phase
RESUMO: O cultivo do algodoeiro no Brasil está concentrado no período chuvoso, e no momento do estabelecimento da lavoura frequentemente há períodos prolongados de baixa radiação solar. O objetivo deste trabalho foi avaliar o desenvolvimento radicular de cultivares de algodoeiro submetidos ao sombreamento na fase inicial da cultura. O experimento foi

7. Maize dry matter production and macronutrient extraction model as a new approach for fertilizer rate estimation
ABSTRACT Decision support for nutrient application remains an enigma if based on soil nutrient analysis. If the crop could be used as an auxiliary indicator, the plant nutrient status during different growth stages could complement the soil test, improving the fertilizer recommendation. Nutrient absorption and partitioning in the plant are here studied and d

8. Plant growth analysis and seed vigor expression: effects of soil waterlogging during rye plant development
This study aimed to evaluate the growth, assimilate partitioning and seed vigor expression of rye seeds subjected to waterlogging during development. The experimental design was completely randomized with six replications and three treatments. The treatments involved different waterlogging periods: a) no waterlogging; b) single waterlogging of three days; an

9. Protein metabolism, feed energy partitioning, behavior patterns and plasma cortisol in Nellore steers with high and low residual feed intake
The objective was to evaluate protein turnover, nitrogen balance, feed energy partitioning, behavior patterns and plasma cortisol in Nellore (B. indicus) cattle with high and low residual feed intake (RFI = actual minus expected dry matter intake). Seventy-two Nellore steers (16 to 21 months-old, 334±19 kg initial body weight) were fed a feedlot diet for 70

10. Physiological response of oil palm interspecific hybrids (Elaeis oleifera H.B.K. Cortes versus Elaeis guineensis Jacq.) to water deficit
Water supply is the main yield-limiting abiotic factor of oil palm in Colombia. To determine the effect of water deficit on the physiology of oil palm and to assess the tolerance degree to this condition, interspecific Elaeis oleifera versus Elaeis guineensis 'U1273', 'U1859', 'U1914', and 'U1937' hybrids were planted for 60 days in soil with different water

11. Tillering and biomass partitioning of Mombasa grass under nitrogen fertilization during regrowth
Biomass partitioning in forages is highly variable during plant development and with the rate of nutrient supply. This study was carried out with the objective to evaluate the tillering pattern and biomass partitioning of Mombasa grass (Megathyrsus maximus cv. Mombaça) subjected to rates of nitrogen (N) during regrowth. The treatments consisted of three wee

12. Effect of irrigation water salinity and cutting age on the components of biomass of Echinochloa pyramidalis
The objective was to evaluate the effect of salinity of irrigation water and different cutting ages on the biomass components of Echinochloa pyramidalis. Seedlings were planted in plastic pots (volume of 8 L) with sandy-textured Quartzarenic Neosol, under greenhouse conditions. The design was completely randomized in split plots with salinity levels (0.75, 2
