Efectos del carbón mineral en la morfofisiología de plántulas de cacao tipo nacional Theobroma cacao L.

Abstract

The use of charcoal has historically been a widely used nutritional source due to its goodness, nowadays there are many uses for this mineral compound not destined for incineration due to its chemical and physical properties. Studies are being carried out todetermine its use in agriculture, with benefits attributed to improve the physical, chemical, and biological structure of soils. For this study, a factorial experiment was used with a completely randomized design (since all possible combinations of treatments are studied) completely randomized (the distribution of treatments is completely randomized in the experimental units throughout the experiment), since two study factors were manipulated simultaneously under homogeneous conditions of the environment and the experimental material. The study factors were: Charcoal dose (0-10-15-20grams/kg soil), bag size (26 x 16 and 20 x 12 cm). The use of charcoal had an influence directly proportional to the dosage on morphological and physiological variables, in 80% of the roots in seedlings originated from seeds with a 1/3 cut, changes from axonomorphic to fasciculate structure were observed. The use of charcoal improves the physical properties of the soil, improves the root area which leads to a greater leaf area, making the use of this mineral in agriculture convenient.
