1. Nitrogen fertilization split in green corn under rainfed system
ABSTRACT The objective of this work was evaluating the nitrogen fertilization splitting on the performance of green corn, grown in rainfed system. The experiment was carried out in Forquilha, Ceará state. Two varieties of corn (Sweet and Gorutuba) were used in the experiment, grown in five types of nitrogen fertilization in the crop cycle (one; three; six;

2. Inoculation with Azospirillum combined with nitrogen fertilization in sorghum intercropped with Urochloa in off-season
ABSTRACT The objective of this work was to evaluate the management of nitrogen fertilization in grains of sorghum inoculated or not with Azospirillum brasilense in single crop or intercropped with Urochloa brizantha (cv. Paiaguás) in the off-season. The experimental design was a completely randomized block design with four replications, in a 2 x 2 x 3 facto

3. Influence of irrigation frequency and nitrogen concentration on Tifway 419 bermudagrass in Brazil
ABSTRACT Tifway 419 Bermudagrass is widely used on athletic fields, requiring irrigation and fertilization for its maintenance; however, little information is available for Bermudagrass management in tropical countries, as Brazil. Thus, this study aimed to evaluate the effect of irrigation frequency and nitrogen (N) fertilization on the development of Tifway

4. Digital imaging of coffee leaves under different nitrogen concentrations applied to soil
ABSTRACT Brazil is the largest Coffea arabica L. producer and exporter in the world market. In view of the need for nitrogen fertilization, the objective of this work was to evaluate the use of digital images of coffee leaves as a function of nitrogen concentration and cultivars, as well as to evaluate the most adequate sampling of this technique to predict

6. SALINE WATER AND NITROGEN FERTILIZATION ON LEAF COMPOSITION AND YIELD OF CORN
RESUMO A ausência de drenagem associada a elevada evapotranspiração e precipitações irregulares contribuem para o acúmulo de sais no solo reduzindo a absorção de nutrientes e a produtividade. O manejo nutricional é importante para que a cultura expresse seu máximo potencial produtivo, sendo o nitrogênio o macronutriente mais requerido pela cultura

7. BIOMASS, GAS EXCHANGE AND PRODUCTION OF CHERRY TOMATO CULTIVATED UNDER SALINE WATER AND NITROGEN FERTILIZATION
RESUMO O cultivo de tomate cereja no semiárido do Nordeste brasileiro é limitado pela escassez hídrica, por isso é comum o uso de fontes de águas com elevadas concentrações de sais nessa região, que causam efeito deletério nas plantas, podendo ser amenizado por meio de estratégias de manejo, destacando-se a adubação com nitrogênio.

8. Topdressing nitrogen fertilization associated with trinexapac-ethyl on industrial quality of oat grains
ABSTRACT Nitrogen fertilization, besides increasing productivity, can favor the production of well-formed, large, and heavy grains, which are traits valued by the oat processing industry. However, high nitrogen (N) doses may lead to plant lodging, which could be solved by using growth retardant. This study aimed to evaluate the industrial quality of white oa

9. Nitrogen top-dressing fertilization of maize cultivated in single and twin-row systems
ABSTRACT The aim of this study was to evaluate the effects of cropping systems (single and twin-rows) and N fertilizer rates in the second top-dressing on the agronomic performance and relative economic returns of maize. The experiment was conducted in a randomized block design, with subplots and three repetitions. The plots were composed of two cropping sys

10. MORPHOGENIC AND STRUCTURAL CHARACTERISTICS OF MARANDU GRASS AFFECTED BY FERTIGATION WITH TREATED SEWAGE EFFLUENT AND CUTTING HEIGHT
ABSTRACT The response of biomass flow components of forage from the interaction between fertigation with wastewater and cutting height during the year is little known. The objective of this work was to verify the responses of morphogenic and structural characteristics of Urochloa brizantha as a function of fertigation application strategies with sewage treat

11. Preharvest nitrogen application affects quality and antioxidant status of two tomato cultivars
ABSTRACT Intensive horticultural crop production usually involves challenges from excessive application of fertilizer, mainly nitrogen (N). The effect of N fertilizer on the fruit quality and antioxidant status of two cherry tomato cultivars (Caballero and Victoria) under greenhouse conditions was performed. Nitrogen treatments were applied ranging from cond

12. PRODUCTIVITY OF IRRIGATED JAMBU UNDER SOIL-WATER STRESSES AND NITROGEN DOSES
ABSTRACT Jambu (Acmella oleracea (L.) R.K.) is a short-cycle leafy vegetable from the Amazon region, which needs an adequate availability of water and nutrients, mainly nitrogen, to obtain a rapid mass increase. This research aimed to study the effect of different soil-water stresses and nitrogen doses on jambu cultivation in the state of Pará. The experime
