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. Author(s): FERREIRA, E. P. de B.; MELO, L. C.; SOUZA, T. L. P. O. de; FARIA, L. C. de; PEREIRA, H. S. 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
Pod positioning and grain yield of common bean as affected by sowing density, nitrogen fertilization and fertilization depth. Author(s): SILVA, J. G. da; FERREIRA, E. P. de B.; NASCENTE, A. S.; SARMENTO, P. H. L. 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
Tillering dynamics in massai grass fertilized with nitrogen and grazed by sheep. Author(s): POMPEU, R. C. F. F. 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... ...

Nitrogen fertilization affects yield and fruit quality in pear. Author(s): NAVA, G. Repository: BDPA Publication year: 2019
Nitrogen sufficiency index for estimating nitrogen fertilizer requirement of irrigated rice. Author(s): SANTOS, A. B. dos; SILVA, M. A. S. da; SILVEIRA, P. M. da; STONE, L. F. 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
Productivity and gas exchanges of the common bean subjected to inoculation and nitrogen fertilization. Author(s): FERREIRA, E. P. de B. Beans are one of the main foods consumed in Brazil. It is considered an essential ingredient in the basic diet of Brazilians. As a management practice, aiming to supply N and increase crop productivit... ... Repository: BDPA Publication year: 2021
Could biochar and green manure be a substitute for synthetic nitrogen fertilization to guarantee rice grain yield and decrease greenhouse gas emissions? Author(s): SILVA, M. A. S. da; SANTOS, A. B. dos; MADARI, B. E.; CARVALHO, M. T. de M. The objective of this study was to find a feasible alternative to the use of nitrogen fertilizers for smallholders and commercial farming in tropical flooded rice systems. Repository: BDPA Publication year: 2018
Role of slow-release nanocomposites fertilizers on nitrogen and phosphate availability in soil. Author(s): FOSCHINI, M. M.; OLIVEIRA, C. R. de Repository: BDPA Publication year: 2017
Ammonia volatilization, dry matter yield and nitrogen levels of Italian ryegrass fertilized with urea and zeolite. Author(s): BERNARDI, A. C. de C.; OLIVEIRA, P. P. A. The nitrogen loss by ammonia volatilization is one of the main factors for low efficiency of N-urea applied on the soil surface. The reduction of losses by volatilization can be obtained with the addi... ... Repository: BDPA Publication year: 2010
