Efeito da omissão de macronutrientes em sisal

Abstract: ( 1 ) Apresentado no XVIII Congresso Brasileiro de Ciência do Solo, realizado em Salvador (BA), em 1981. Recebido para publicação a 27 de abril de 1981. ( 2 ) Com bolsa de suplementacão do CNDCT-CNPq. RESUMOPlantas de sisal (Agave sisalana Perr.) foram cultivadas em casa de vegetação, em vasos contendo areia lavada e irrigados com solução nutritiva completa e com soluções nutritivas com a omissão de cada macronutriente.

“…In the total dry matter the treatment more limiting was the omission of calcium, following by boron and nitrogen. The decreasing order of the nutrients in function of the reduction of total matter was: Ca > B > N > K > Mn > P > Fe > Mg > Zn > Cu > S. with rough aspect to the touch, very similar to the result obtained by Salgado, Azzini, Feitosa, and Hiroce (1982) in other cultives of fibers, the sisal. With the intensification of the deficiency there was premature fall of the leaves, very characteristic symptoms of the deficiency of this nutritious one, because it affects the chloroplast directly according to Cobra Netto, Accorsi, and Malavolta (1971).…”

“…Another relevant fact is to be this nutrient to be extremely necessary for the appropriate operation of the meristem, besides being indispensable to the mitosis, process of cell reproduction (Reis, 2011). The observed results were very similar to the obtained by Salgado et al (1982) in sisal and Viégas et al (2014) in curauá.…”
