Abstract(s)
A fava para indústria desempenha uma importante função agronómica e ambiental nos sistemas de
produção do Vale do Tejo. Em 2019 procedeu-se à monitorização do desenvolvimento e
crescimento da variedade de faveira Histal cuja produção se destina à indústria para congelação.
Observaram-se e registaram-se as fases de desenvolvimento, a população potencial e produtiva, o
peso verde e o peso seco da planta. Foram avaliados os componentes de rendimento e a
quantidade de macronutrientes extraídos e restituídos ao solo. A população produtiva foi de 8,7
plantas/m2
, o que representou uma emergência de 90% da população potencial. O número médio
de ramificações por planta foi de 5,3. Em média cada planta produziu 18 vagens comerciais (60%
do número total) que originaram 75,5 grãos/planta. As condições meteorológicas adversas, ao longo
do ciclo cultural, tiveram um impacto negativo na fase de floração e vingamento das vagens,
condicionando a produtividade.
The faba bean for industry plays an important agronomic and environmental function in the production systems of the Tagus Valley. In 2019, the development and growth of the Histal faba bean variety was monitored. The phenological growth stages, the potential and productive population, the fresh weight and the dry weight of the plant were observed and recorded. The yield components, amount of macronutrients extracted and returned to the soil were evaluated. The productive population was 8,7 plants/m2 , which represented an emergency of 90% of the potential Rev UI_IPSantarém. 2020; 8(3): 34-48. 36 population. The average number of branches per plant was 5,3. On average, each plant produced 18 commercial pods (60% of the total number) that originated 75,5 grains/plant. Adverse meteorological conditions, throughout the cultural cycle, had a negative impact on the flowering and development of the pods, affecting the yield.
