Nitrogen redistribution to sorghum grains as affected by plant competition
(Springer, 1993-10-01)
An experiment was conducted to study nitrogen absorption and translocation in grain sorghum plants during their reproductive growth. Sorghum was grown in four row spacings: 50 and 70 cm in single rows, 80 and 120 cm in ...
Nitrogen fertilisation efficiency and wheat grain yield affected by nitrogen doses and sources associated with Azospirillum brasilense
(2019-10-03)
The nitrogen fertilisation management should focus on increasing fertilisation efficiency in favour of a more sustainable and productive agriculture. Thus, this study aimed to evaluate the effect of inoculation with ...
MORPHOGENESIS, STRUCTURAL CHARACTERISTICS AND FORAGE ACCUMULATION OF Megathyrsus maximus BRS ZURI SUBJECTED TO NITROGEN FERTILIZATION
(Inst Zootecnia, 2020-01-01)
Nitrogen fertilization permits to increase the carrying capacity of pastures; however, the use of high doses can have negative effects on the growth of forage grasses. Therefore, the aim of this study was to evaluate the ...
Effects of hand weeding strip and nitrogen fertilizer on corn plants
(2005-01-20)
The objective of the present research was to evaluate effects of different strip weed control associated with nitrogen fertilizer on corn applied after planting. The experiment was set and conducted in Botucatu, São Paulo ...

Nitrogen budget in a soil-plant system after brachiaria grass desiccation
(Taylor & Francis Ltd, 2014-04-01)
Brachiaria spp. have been grown in a variety of cropping systems and are often terminated with herbicides, which may cause nitrogen (N) loss from the soil-plant system. In this study ammonia (NH3-N) loss by shoots and N ...
Effect of nitrogen supply on growth and photosynthesis of sunflower plants grown in the greenhouse
(Elsevier B.V., 2004-05-01)
The effects of nitrogen availability on growth and photosynthesis were followed in plants of sunflower (Helianthus annuus L., var. CATISSOL-01) grown in the greenhouse under natural photoperiod. The sunflower plants were ...

Avaliação de cultivares de trigo para eficiência de uso do nitrogênio e seus componentes
(Universidade Tecnológica Federal do ParanáPato BrancoBrasilDepartamento Acadêmico de Ciências AgráriasAgronomiaUTFPR, 2014-06-10)
Accumulation and redistribution of N in the plant is an important factor for yield and grain quality. The identification of genotypes with high potential for nitrogen use efficiency (NUE) is of extreme importance in breeding ...
