Performance of tanzania grass grow in nutrient solutio with suppression of macronutrients

Abstract

The effects of nutritional disorder depends on the plant nutrient and the crop species. The experiment was carried out to evaluate the effect of nutrients on the nutrition and plant growth of Panicum maximum cv. Tanzania, grown in nutrient solution. Plants of
Tanzania grass were grown in pots containing nutrient solution corresponding to seven treatments, one complete and the others with individual absence of N, P, K, Ca, Mg and S, arranged in a randomized  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 the levels of macronutrients were determined. The removal of nutrients in Tanzania grass resulted in a decrease both of
dry matter production, with emphasis on nitrogen, and nutrient uptake, producing typical visual symptoms for each nutrient. Macronutrient levels in the shoots of grass 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
