“…These significant results for these variables were also observed by Véras et al (2014) when studied the use of cow urine at 1% and 5% as biofertilizer in Tamarindus indica. The H and D values observed in cupuaçu plantlets are even higher (115% and 150%, respectively) than those found by Nascimento et al (2017) when using biofertilizers produced with cow manure and organic material on cupuaçu, after seedling emergence, with one application per week for 72 days.…”

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.

Objective: The aim of this study was to evaluate the behavior of cupuaçu tree (Theobroma grandiflorum) seedlings as a function of agro-industrial waste. Method: The influence of agro-industrial waste on the development of cupuaçuzeiro seedlings was evaluated. Treatments included different proportions of organic waste (açaí ash, dendê compost and cattle manure) in proportions of 5%, 10%, 15% and 20% in relation to 3 kg of soil. Finally, morphological and physiological variables were determined. Result and Conclusion: The experimental data was analyzed using analysis of variance. Significant means were then compared using the Tukey test, with a significance level of 5%. From the results obtained, it was observed that one of the agro-industrial residues has the potential to act as an alternative substrate in the production of Theobroma grandiflorum seedlings. Researchimplications: The Theobroma grandiflorum species stands out as being extremely important, since its products and by-products are widely accepted in domestic and foreign markets, as well as contributing to Agroforestry Systems. In addition, there is a need to study alternative substrates, especially those generated on a large scale, considering the need to promote proper disposal with sustainable use. Originality/value: In the current scenario, with regard to the destination and final disposal of solid waste, there is a need to look for sustainable alternatives aimed at reusing this waste, especially in agriculture.
