“…In the diameter of the head of lettuce, a quadratic trend was observed for the cultivar Crisp Lucy Brown cultivated under shading mesh (RP) and in the absence of shading mesh (RA) and Crisp Vanda in shading mesh, with the estimated doses of fertilizer 8.63; 9.03 and 7.98% provided the largest head diameters 41.33, 46.19 and 57.88 cm, respectively. According to Farias et al (2017), the use of organic fertilizers is fundamental to improve the development of lettuce, since the addition of organic compounds increased the growth and production of lettuce cv. Babá de Verão.…”

The objective of the present work was to evaluate the effect of the organo-mineral foliar fertilization and the environment in the lettuce crop. The work was carried out in a soil classified as Quartzipsamments, with loam texture and low initial availability of nutrients. The experimental design used was randomized blocks with a factorial arrangement 2 x 2 x 5, corresponding to two cultivars of lettuce (Crisp Vanda and Crisp Lucy Brown), two environments (with and without shading mesh at 35%) and five concentrations of Ferti Garden liquid fertilizer multipurpose via foliar, (0; 5; 10; 15 and 20% of the product in the solution), with 4 repetitions, containing 20 plants. Soil preparation was done manually and fertilized with 30 m 3 hectare-1 of bovine manure, dead cover was also used. The foliar fertilizer was applied three times, at intervals of seven days, through a constant pressure sprayer, from 12 days after transplanting the seedlings. At 33 days after the transplant the plants were harvested and evaluated in the variables of head diameter, number of leaves, fresh matter and productivity. The cultivar Crisp Lucy Brown proved to be more demanding in terms of luminosity and mineral nutrition in relation to the cultivar Crisp Vanda. Therefore, the highest development and productivity of the Crisp Lucy Brown cultivar is obtained without shading mesh, with fertilization before sowing of 30 kg ha-1 of fowl bed and fertilization with 9.1% of the foliar fertilizer. While for the cultivar Crisp Vanda the highest productivity is obtained with shading mesh, and only with fertilization before sowing.

Farias et al (2017), afirmam que o uso de adubo orgânico é fundamental para o bom desenvolvimento da alface. Além disso, o uso de adubação de origem animal implementa uma filosofia de aproveitamento dos recursos renováveis locais, promovendo sustentabilidade ecológica (TREADWELL et al, 2007).…”

The objective of this research was to characterize the production of lettuce under different layers of water and levels of bovine manure. The experiment was carried out at UFAL, Campus de Arapiraca. The design was completely randomized, arranged in a 5 x 6 factorial, with three replications.The treatments consisted of five water depths (L): 50, 75, 100, 125 and 150% of the crop evapotranspiration (ETc) and six levels of bovine fertilization: 0 (control), 50, 75, 100, 125 , and 150% of the recommendation. The localized drip irrigation system was used. At 30 days after transplanting, the harvest was performed. The data were tabulated and submitted to analysis of variance by the F test (p <0.05) by the software R. The water depth factor influenced the chlorophyll index a. There was interaction between the factors for water productivity. The efficiency in the use of organic compost was influenced by the addition of fertilizer.

“…Studying the interaction of soil cover with organomineral fertilization is a necessity because, in vegetable cultivation, techniques of using organic fertilizers have been favored by the producers (Farias et al, 2017), mainly for inhibiting the weeds infestation, which can cause significant losses in yield when not controlled. In addition, it can minimize soil problems due to erosion, making it more productive and providing greater production and quality of vegetables (Souza et al, 2016).…”

Bell pepper crop is among the ten most important vegetables in Brazil. Using organic fertilizers as an alternative to mineral fertilizers is an integral part of the search for safe food from organic production systems. The objective of the present study was to evaluate the quality of red bell pepper fruits, grown under soil cover and organic and or mineral fertilization. Treatments consisted of three soil cover types [no cover; covered with carnaúba straw (Copernicia prunifera) and covered with weeding] and fertilizers [100% organic (OF) and 0% mineral (MF); 100% OF and 50% MF; 50% OF and 50% MF; 50% of OF and 100% of MF and 0% of OF and 100% of MF], the design used was randomized blocks with a split plot arrangement of 3 x 5 and 4 replicates. Analyzed variables were color, firmness, pH, soluble solids (SS), titratable acidity (TA), ratio (SS/TA), vitamin C, carotenoids, total flavonoids and phenols. For bell pepper fruits, soil cover with carnaúba straw provided better carotenoid content. Organomineral fertilization increased carotenoids and phenols accumulation and the treatment with only organic fertilization resulted in lower contents of these bioactive compounds.
