Abstract

The effects of nutritional disorder depend on the plant nutrient and crop species. The experiment aimed to evaluate the effect of macronutrients on nutrition and  growth of Panicum maximum cv. Tanzania, grown in nutrient solution. Plants of Tanzania guinea
grass were grown in pots containing nutrient solution corresponding to seven treatments, with the complete solution and with absence of nutrients N, P, K, Ca, Mg and S, arranged in a randomized block design with three replications. After describing the symptoms of the nutrients not applied, the plants were harvested 45 days after transplantation and divided into roots and shoots, and then the macronutrients levels were determined. The suppression of macronutrients in Tanzania guinea grass resulted in lower dry matter production, with emphasis on nitrogen, and lower nutrient uptake, causing typical visible symptoms according to each nutrient. Macronutrient levels in the plant shoot in nutrient solution and omitting the nutrients were, respectively: N = 23.6 to 11.4, P = 1.7 to 0.3, K = 15.2 to 2.0 , Ca = 3.8 to 0.7, Mg = 3.0 to 0.3 S = 1.0 to 0.6 g kg-1.
