RENDIMENTO DE TOMATEIRO INDUSTRIAL CULTIVADO COM UREIA TRATADA COM NANOCELULOSE

Abstract

The increase in the world population, leads to a greater demand for food, thus, it is stipulated that the number of world inhabitants will reach around 9 billion in 2050. In this way, the use of organomineral such as nanofibrillated cellulose came to improve production in the same space-time and reduce the exaggerated use of mineral fertilizers and meet the demand for food with the increase in population. The objective of the research was to evaluate the efficiency of the use of treated nanocellulose in the productivity of industrial tomato (Sollanum lycopersicon). The planting was carried out at Instituto Federal Goiano – Campus Morrinhos (Latitude 17º48'50.4" S; Longitude 49º12'16.5'' W; Altitude: 902 m) in a randomized block design with six treatments and five replications. were composed of 0.0, 60, 90, 120 and 150 kg ha-1 of N added through urea treated with nanofibrillated cellulose and an additional treatment of 120 kg ha-1 with conventional urea fertilization. nanocellulose was carried out at the beginning of planting in the subsurface layer, and the conventional urea was carried out in the superficial layer at the base of the plant. At 126th day after planting, total fruit yield (TFP), green fruit yield were evaluated. (PFV), ripe (PFM) and rotten (PFP), all in t ha-1.No significant statistical differences (p>0.05) were observed for the proposed treatments, for any of the evaluated parameters, except for green fruits, in which ran statistical differences at 5% of p probability between treatments.
