Resumo
Características fisiológicas da semente e de grãos podem determinar a qualidade das mesmas e a qualidade pode estar relacionada com o manejo da cultura, tais como a disponibilidade de água, nutrientes, controle de pragas e doenças. Dentre os nutrientes, o nitrogênio é um dos fatores importantes na produtividade e o zinco está envolvido em processos bioquímicos que são essenciais para o crescimento e desenvolvimento da planta. O cultivo da ervilha nos cerrados vem ganhando espaço e tem sido uma boa opção para o plantio na entressafra, sob regime de irrigação. O experimento foi conduzido na FEP/FE/UNESP - Campus de Ilha Solteira e o delineamento experimental adotado foi de blocos casualizados em esquema fatorial 4 x 4 (doses de nitrogênio x doses de zinco), com três repetições. O trabalho objetivou avaliar o efeito do N e Zn no conteúdo de proteínas, aminoácidos, açúcar livre, amido e polissacarídeos solúveis em água (WSP) nos grãos e sementes de ervilha, cultivar Utrillo, cultivadas em solo de cerrado. Os resultados obtidos permitem verificar que há interação entre a adubação nitrogenada e zinco no conteúdo das reservas dos grãos e de sementes, sendo que o teor de açúcar livre nos grãos verdes apresenta incremento linear com o aumento da dose de N entre 60 e 240 kg ha -1 . A análise dos dados mostra ainda que, o teor de clorofila nos grãos verdes aumenta com as doses crescentes de Zn e N. Verifica-se também, que não houve efeito do Zn e do N na produção.
The physiological characteristics of the seed and grains can be determine the quality of the same ones and, the quality can be related with the handling of the culture, such as the available of water, nutrients, control of curses and disease. The nitrogen is one important nutrient and it is a very important factor on the productivity and the zinc is involved in biochemical processes that are essential for the growth and development of the plant. The cultivation of the pea in the cerrado is enhanced and it has been a good option for the planting in the time between harvests, under irrigation management. This experiment was realized in FEP/FE/UNESP - Campus de Ilha Solteira and the experimental design used was the random blocks in the factorial design 4 x 4 (dose of nitrogen x dose of zinc), with three repetitions. The work aimed at to evaluate effect of N and Zn in the protein content, amino acid, free sugar, starch and soluble polysaccharides in water (WSP) in the grains and pea seeds, to cultivate Utrillo, cultivated in cerrado soil. The obtained results allow to verify that there is interaction between the nitrogen fertilization and zinc in the content of the reservations of the grains and of seeds, and the content of free sugar in the green grains presents linear increment with the increase of the dose of N between 60 and 240 kg/ha. The analysis of the date display although, the chlorophyll content, in the green grain, increases with the growing doses of Zn and N. Also verifies, that there was not effect of Zn and of N in the production.
