The use of phytonanoparticles in agriculture could decrease the use of fertilizers and therefore decrease soil contamination, due to their size being better assimilated in plants. It is important to mention that the nanofertilizer is slow-releasing and improves plant physiological properties and various nutritional parameters. The influence of soil and foliar applications of phytonanoparticles of ZnO with the Moringa oleifera extract under three concentrations (25, 50, and 100 ppm) was evaluated on the cherry tomato crop (Solanum lycopersicum L.). Synthesis of the phytonanoparticles was analyzed with ultraviolet-visible spectroscopy (UV-Vis) and infrared transmission spectroscopy with Fourier transform (FT-IR), as well as the analysis with the dynamic light scattering (DLS) technique. The morphometric parameters were evaluated before and after the application of the nanoparticles. The minerals’ content of fruits was done 95 days after planting. Results showed that soil application was better at a concentration of 25 ppm of phytonanoparticles since it allowed the greatest number of flowers and fruits on the plant; however, it was demonstrated that when performing a foliar application, the fruit showed the highest concentrations for the elements Mg, Ca, and Na at concentrations of 511, 4589, and 223 mg kg−1, respectively.

The purpose of this study was to investigate the effect of deficit irrigation applications on the chemical compounds and mineral contents of tomatoes. In the study, a tomato (Solanum lycopersicum L) hybrid "Nehir F1" was grown in a greenhouse that had a natural light, heating and ventilation system and was covered with polycarbonate material. The tomatoes were irrigated every three days by applying 60% (T1), 80% (T2), 100% (T3) and 120% (T4) of the evaporation value after reading and determining it from the reduced evaporation pan. The tomatoes were harvested at the red-ripe maturity stage and analyses were performed. As a result of the study a total of 60 compounds were determined in the tomato samples by using Gas chromatography/Mass Spectrometer system. The most abundant compounds in terms of both amount and variety in the tomatoes were identified as ketones, sugars and fatty acid esters. Furthermore, the mineral content of the tomatoes changed according to the irrigation application. K, Mg, P, Ca and Fe were accumulated in the all tomatoes samples.

Objective: To evaluate the effect of fertigation and granular fertilizer to the soil interacting with foliar application of analogue brassinosteroids in Solanum lycopersicum L. Design/Methodology/Approach: The treatments were Fertigation (F), Fertigation plus brassinosteroids (F + BR), Granular fertilization (FG) and Granular fertilization + brassinosteroids (FG + BRs). A completely randomized design with four replicates was used, where one plant from each treatment represented the experimental unit. Plants (45 days-old) were sprayed with 2 mg L-1 of Brassinosteroid CIDEF-4 and subsequent applications were made every 28 d. Plant height and stem diameter were measured 92 d after transplantation, while the yield was obtained by weighing completely red fruits. An analysis of variance was performed using the GLM procedure and the Tukey means comparison test (p?0.05) with the SAS 9.3 program. Results: Fertigation induced greater plant growth and reproduction of the tomato compared to the granular fertilizer with, or without foliar application of the analogue brassinosteroid. Treatments with granulated fertilizers decreased plant height by 10.36% and 10.45% compared to fertigation. Tomato yield with granulated fertilization, with or without Br, corresponded to 76.6% and 75.80% of what was achieved with Fertigation + Br. Study limitations/Implications: The absence of a stressful environment did not favor the application of the analogue brassinosteroid. Findings/conclusions: Fertigation induces greater growth and yield of tomato under field conditions; and environmental temperature homogeneity did not favor morphological nor physiological expression of the analogue brassinosteroid.

Research on the antioxidant lycopene of tomato fruit (Solanum lycopersicum L.) blended in frying fat from catfish (Clarias sp) oil has been done. The purpose of this research is to determine the antioxidant activity of tomato lycopene before and after being grounded into frying fat and determine the quality of frying fat after being grounded with tomato lycopene. The antioxidant activity of tomato lycopene is determined by the DPPH (2,2-diphenyl-1-picrylhydrazyl) method. Analysis of frying fat quality includes determination of pH, determination of FFA (free fatty acid) levels, determination of total fat content, measurement of water content, peroxide number and organoleptic observation. Antioxidant activity of tomato lycopen was very high, namely with inhibition value of 89.79%; 90.34%; 91.49% and 92.10%. Frying fat analysis showed high antioxidant activity of lycopene tomatoes with 50.67% inhibition; 51.63%; 51.39% and 51.23%. The results of the analysis of the quality of frying fat are nearly same with SNI quality standards, except for peroxide numbers. Keywords: tomato, lycopene, antioxidants, frying fat, catfish, DPPH

Objetivo: Evaluar el desarrollo de plántula de tomate indeterminado bajo condiciones protegidas, aplicando  tres enraizadores  y un testigo para aumentar la producción del cultivo en la región. Diseño/metodología/aproximación: se utilizó bajo un diseño experimental en bloques completamente al azar, el cual consistió de cuatro tratamientos correspondiendo a cada uno de los bloques, donde cada bloque pertenecía a cuatro charolas de unicel de 200 cavidades con sustrato de BM2, con cuatro repeticiones cada uno, teniendo 15 unidades experimentales por tratamiento, sumando un total de 60 unidades experimentales, teniendo un total de 240 plántulas de tomate por todo el experimento. Resultados: Como resultado se obtuvo que el enraizador de Phyto Root  tuvo un gran efecto en cuanto al desarrollo de altura, grosor de tallo, numero de hojas, biomasa aérea y peso del cepellón, parámetros importantes que debe tener una plántula para su desarrollo y crecimiento al momento de trasplante a campo. Limitaciones del estudio/implicaciones: El manejo agronómico desde la siembra en charolas, es necesario que sea uniforme en todos los tratamientos y las repeticiones para tener mejores resultados en cuanto el efecto de los enraizadores. Hallazgos/conclusiones: Para obtener plántulas de buena calidad en el momento de trasplante a campo se le recomienda a la empresa y a los productores de plántulas utilizar el tratamiento de Phyto Root, ya que fue la que mejor respuesta tuvo.
