Substrate for cupuaçu plantlets and the influence of cow urine as biofertilizer
Abstract The use of organic waste as components of substrate to produce fruit plantlets provides alternative materials, easily available and low cost. The aim of this work was to evaluate the effect of substrate and biofertilization with cow urine on the growth of cupuaçu plants (Theobroma grandifl...

| description | Abstract The use of organic waste as components of substrate to produce fruit plantlets provides alternative materials, easily available and low cost. The aim of this work was to evaluate the effect of substrate and biofertilization with cow urine on the growth of cupuaçu plants (Theobroma grandiflorum) in an organic production system. A factorial experiment was conducted in a completely randomized design with 12 replications including four types of substrates (base mixture; base mixture + coconut fiber; base mixture + cocoa shell and base mixture + sand) with or without biofertilizer application totalizing 96 experimental units. Substrate and biofertilizer influenced the gas exchange and growth of T. grandiflorum plants. The interaction between these two factors significantly affected the dry matter, relative growth rate, net photosynthetic rate, and content of P, K and Mn in the leaves. Each factor, substrate and of cow urine application, independently, influenced the chlorophyll index, the leaf area, diameter, and height of the cupuaçu plants and the contents of N, Ca, Mg, Zn, Fe and Cu in the leaves. The base mixture substrate (composed by soil and organic compost) and fertilization with 1% of cow urine can be indicated to T. grandiflorum plantlets organic production. |
