Durum Wheat Kernel

Moreira, José; Rodrigo, Sara; Pinheiro, Nuno; Costa, Ana Rita P.; Costa, Armindo; Dôres, José; Patanita, Manuel; Maçãs, Benvindo; Leitão, Roberta

Thirteen genotypes of durum wheat were grown in two different environments in Portugal. Grain and ash mineral profile, as well as protein content, test weight, and grain ash content were evaluated. Genotype, environment, and their interaction explains the variation in the quality traits, with the environment having the highest influence. Mineral profile analysis was performed by the μ-EDXRF system: macroelement...

The sustainable intensification of forage production in Mediterranean climates requires technological solutions that optimize the use of agricultural inputs. This study aimed to evaluate the performance of proximal optical sensors in recommending and monitoring variable rate nitrogen fertilization in winter forage crops cultivated under Mediterranean conditions. A handheld multispectral active sensor (HMA), a m...

The current Common Agriculture Policy (CAP) foresees a reduction of 50% in the use of herbicides by 2030. This study investigates the potential of integrating remote sensing with a low-cost RGB sensor and variable-rate technology (VRT) to optimize herbicide application in a ryegrass (Lolium multiflorum Lam.) fodder crop. The trial was conducted on three 7.5-hectare plots, comparing a variable-rate application (...


Remote Monitoring of Crop Nitrogen Nutrition to Adjust Crop Models: A Review

Silva, Luís; Conceição, Luís Alcino; Lidon, Fernando Cebola; Maçãs, Benvindo

Nitrogen use efficiency (NUE) is a central issue to address regarding the nitrogen (N) uptake by crops, and can be improved by applying the correct dose of fertilizers at specific points in the fields according to the plants status. The N nutrition index (NNI) was developed to diagnose plant N status. However, its determination requires destructive, time-consuming measurements of plant N content (PNC) and plant...


Otimização da aplicação de fertilização azotada em trigos melhoradores

Costa, Maria Natividade; Rosa, Elizabete; Martins, P.; Espada, Rita; Boteta, Luis; Costa, Ana Rita; Pinheiro, Nuno; Gomes, Conceição; Bagulho, Ana Sofia

O projeto FERTITRIGO - Otimizaçao da fertilização azotada em trigos melhoradores - foi desenvolvido na sequência de outros e tendo como base o conhecimento de que os principais fatores que influenciam a produção e a qualidade do grão de trigo são os genéticos (variedade), as condições climáticas e a as técnicas culturais, com destaque para a fertilização azotada.
