Deficiencies of the macronutrients and boron. The presente work was carried out in order to study: a - The effect of the omission and presence of the macronutrients and boron on the growth of the plants - variety Asgrow 40; b - deficiency symptoms of macronutrients and boron in the same variety; c - the effects of the deficiencies of each macronutrient and boron on the dry matter production and on the chemical composition of the plant-variety Asgrow 40. I - Deficiencies of the macronutrients Young peas plants (Pisum sativum, L.), variety Asgrow 40 were grown in pots containing pure quartz. Several times a day they were irrigated by percolation with nutrient solution. The treatments were: complete solution and deficient solution, in which each one of the macronutrient was omitted as well boron. Soon as the malnutrition symptoms apperared, the plants were harvested and divided into: roots, stalks, inferior and superior leaves, flowers, husk containing the seeds. The dry matter was analysed chemically. Conclusions: 1 - Symptoms of malnutrition were observed for N, P, K, Ca and B; 2 - The omission of the macronutrients and boron affected the dry matter production, excepted for magnesium and or sulphur; 3 - The nutrient content in the dry matter, expressed in porcentages (%) and or parts per million (ppm) in deficient leaves and healthy leaves were:Downloads
