Response of low land rice to nitrogen fertilization under different irrigation regimes. The objective of this study was to evaluate response of irrigated rice to nitrogen fertilization under different irrigation regimes. Repository: BDPA Publication year: 2014
Fertilizers with coated urea in upland rice production and nitrogen apparent recovery. Author(s): CARVALHO, M. da C. S.; NASCENTE, A. S.; TEIXEIRA, P. C. Urea is the most used N fertilizer for upland rice, however, a great percentage of N loss can occur with the use of this fertilizer. The use of products that provide reduction of N loss for urea ferti... ... Repository: BDPA Publication year: 2016
Gas exchange in Massai grass fertilized with nitrogen and grazed by sheep. Author(s): POMPEU, R. C. F. F.; BEZERRA, M. A. The knowledge of gas exchanges in forage plants is essential for a better understanding of the process of forage biomass production in pasture. This study evaluated the gas exchange in massai grass fe... ... Repository: BDPA Publication year: 2020
Nitrogen sources on agronomic traits in carioca common bean lines developed under mineral nitrogen fertilization. Despite the importance of symbiotic nitrogen fixation (SNF) as a nitrogen source for leguminous plants, there are few reports of common bean breeding programs aiming at efficiency in SNF. This study a... ... Repository: BDPA Publication year: 2024
Tillering dynamics in massai grass fertilized with nitrogen and grazed by sheep. To evaluate the tillering dynamics of massai grass under rotational sheep stocking and fertilized with nitrogen (control - 0; 400; 800 and 1200 kg ha-1 year-1), this study was carried out, in a comple... ...

Pod positioning and grain yield of common bean as affected by sowing density, nitrogen fertilization and fertilization depth. The positioning of pods in common bean directly affects grain losses in mechanized harvesting. However, only few studies have assessed facttors that can affect pods positioning. The objective of this... ... Repository: BDPA Publication year: 2023
Nitrogen fertilization in off-season corn crop in different Brazilian Cerrado environments. RESUMO: The objective of this work was to assess the grain yield and the economic response of off-season corn (Zea mays) crop subjected to different combinations of starter and topdressing nitrogen fe... ...

Nitrogen fertilization affects yield and fruit quality in pear. Repository: BDPA Publication year: 2019
Zinc loading in urea-formaldehyde nanocomposites increases nitrogen and zinc micronutrient fertilization efficiencies in poor sand substrate. Agricultural output needs significant increases to feed the growing population. Fertilizers are essential for plant production systems, with nitrogen (N) being the most limiting nutrient for plant gro... ... Repository: BDPA Publication year: 2022
Nitrogen sufficiency index for estimating nitrogen fertilizer requirement of irrigated rice. The proper nitrogen management is required to achieve high irrigated rice yield. This study aimed to determine the rice response to nitrogen topdressing doses and calibrate the chlorophyll meter readi... ... Repository: BDPA Publication year: 2019
