Estudos sobre a nutrição mineral do feijão macassar (Vigna sinensis (L) Endl.). V: chave para a identificação de deficiências mineraisResumo
É apresentada uma chave para identificação visual das deficiências de macro e de micronutrientes em Vigna sinensis.
Abstract
Symptoms of deficiency of macro and micronutrients were induced in Vigna sinensis by growing two cultivars in nutrient solution under the necessary treatments. Results there of were used to prepare a key which could be used in the visual diagnosis of mineral deficiencies. As a rule, the information obtained is in agreement with result found in the literature for other legumes. It is noteworthy, however, that symptoms of Mo and Zn first showed up in older leaves.
